Field of the Invention The present invention relates to a wind power generation device that generates power by a main shaft driven generator that is rotated by a wind, and particularly relates to a yaw (YAW) rotation for a wind power generation device. The construction of the sliding bearing of the bearing. [Prior Art] A wind turbine generator is a device in which a rotor head including a wind turbine blade is rotated by a wind force, and a generator is driven to generate electric power by a speed increaser or the like. In addition, the rotor head with the wind turbine blade is connected to the speed increaser and the generator installed in the upper part of the tower. Therefore, the orientation of the rotor head is matched with the constantly changing wind direction. The slewing device of the upper turn. 10A and 10B show an example of the configuration of the prior yaw turning device. The yaw turning device 1A shown in Figs. 10A and 10B is formed by interposing a steel ball nc or the like on the inner wheel 12a of the base member (cabin platen) 11 fixed to the nacelle 3 side rotated on the tower 2, and Between the outer wheel i2b fixed to the stationary tower 2 side, in the illustrated yaw turning device 10, a rolling rolling bearing 12 is used. The instant bearing 12 serves as a rolling bearing of a slewing slewing bearing. In this case, the yaw turning device 1A includes a fixed gear 13' formed on the outer circumference of the outer ring (3) and a drive returning wheel 15 which is rotated by a biasing motor fixedly disposed on the nacelle 3 side. Further, since the driving gear 15 is coupled to the fixed gear (four), the driving gear 15 is rotated around the fixed gear 13 in response to the rotational direction of the yaw center, and the base member U and the yaw motor are moved. 14 is rotated clockwise or counterclockwise with respect to the stationary tower. 141386.doc 201102494 In addition, the symbol 16 in the figure is a brake disc, a 17-series brake mat, and an 18-series brake bracket. Further, in the conventional wind power generator, as described above The slewing bearing 'there is a sliding bearing 2 as shown in Fig. 11. The sliding bearing 20 shown in Fig. 11 is such that the sliding bearing member 23 is interposed in the base 2 on the side of the nacelle 3. The rotating member 21 of the seat member (cabin platen) u and the fixed portion 22 fixed to the stationary tower 2 side. The sliding bearing 20 in this case mainly consists of a fixing portion formed on the upper portion of the tower 2 The lower plane portion above the edge portion 22 receives the moment load generated by the wind load received by the blade, and the sliding bearing member 23 in contact with the plane portion is fixed to the nacelle side. Further, as a radial direction capable of supporting the rotary shaft Loaded spherical surface The movable bearing is disclosed in the case where the sliding material is provided on the wheel side of the rolling bearing portion. (For example, refer to Patent Document 1) [Patent Document 1] JP-A-2006-312965 (Summary of the Invention) The bearing 20 is more suitable for a slewing slewing bearing of a large-scale wind power generator than the rolling bearing 12. That is, since the slewing bearing having a large diameter is required as the size of the wind power generator increases, the rolling bearing 12 having a difficult structure is divided. In other words, the cost of the special product such as the ball bearing 12c is increased, and the ground transportation is limited. On the other hand, since the sliding bearing 20 has a separable structure, it is easy to handle the cost and the ground transportation problem. In response to the large-scale slewing bearing of the wind power generation device. 141386.doc 201102494 Compared with the sliding bearing Shenchengxing dynamic bearing 12, the prostitute m /, has the radial (radius) direction of the inner wheel side and the outer wheel side The gap is large, and 俅B makes the center of the shaft on the tower side and the nacelle side easy to be displaced in the radial direction. That is, the π-moving bearing 20 usually needs about 1 mm in the radial direction. The initial gap, and the u-piece causes the sliding bearing material 23 to wear with continuous operation, so the initial clearance is combined. The T a 1 丨 丨 运转 运转 运转 运转 运转 运转 运转 运转 运转 。 。 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此 因此The displacement of the center of the shaft caused by the shift of the shaft. The offset of the center of the shaft causes the positional relationship of the tilting motor of the nacelle to rotate, and the backlash between the driving side and the fixed side gear changes. The excessively large load is applied to the gears on the driving side and the fixed side, and the smooth operation of the yaw turning device is hindered. Moreover, in the case of the rolling bearing 12, since the gap in the radial direction can be set to 〇~negative, the problem of the gap does not occur. occur. Based on such a background, it is expected that the sliding bearing which is advantageous for the slewing bearing of the wind power generator which has been gradually enlarged in recent years is expected to reduce the gap in the radial direction and reduce the offset of the shaft center. The present invention has been made in view of the above circumstances, and an object thereof is to provide a wind power generator comprising a sliding bearing as a slewing slewing bearing which can reduce a gap in a radial direction to reduce a shift in the center of the shaft. In order to solve the aforementioned problems, the present invention employs the following means. The wind turbine generator according to claim 1 is characterized in that the nacelle provided on the tower is rotatably supported by a slanting sliding bearing, and the slidable sliding bearing is mainly provided to be disposed above the flange formed on the fixed portion. a sliding member between the supporting surface and the rotating portion, and a rotating body disposed between the biasing sliding shaft 141386.doc 201102494 and the rotating portion. According to such a wind power generation device, the upper support surface and the rotary support of the fixed portion are disposed in the fixed portion and the rotary portion which are fixed on the biasing sliding bearing, and the sliding sliding bearing can be reduced in (4) 'There is a eccentric body, using a cylindrical, circular wide gap. In this case, a roller of 0 column, ® shape, or the like can be used. In the invention of the first month, it is preferable that the above-mentioned turning portion is divided into a plurality of moving members in the circumferential direction, and the second moving member is configured to have a support structure over the entire circumference. In addition, the load in the axial direction of the case of the structure is as follows: as long as the sliding bearing material is adjusted to the load, u can be replaced, and even if the (4) is buckled, the damaged portion can be partially replaced. In this case, it is preferable to provide a gap adjusting mechanism for the aforementioned roller follower, thereby making it possible to relax the manufacturing tolerance of the set gap during manufacturing, and finally to localize the damage when the sliding bearing is damaged. The replacement part can also be easily adjusted for the gap. In the above-described invention, it is preferable that the above-mentioned swaying and sliding (four) bearing system has the above-mentioned flange formed on the inner circumferential side and the outer circumferential side of the fixing portion to form a zigzag shape of the upper and lower support faces, and on the (four) side and the outer periphery of the front μ fixed portion. At least the side of the side is provided with the aforementioned rotating body 'by this' to suppress the bending caused by the swaying sliding bearing caused by the moment load. According to the wind power generation device of the present invention, the sliding bearing which is advantageous for the slewing slewing bearing of the large-scale wind power generating device can reduce the offset of the shaft center by reducing the gap in the radial direction, thereby preventing unnecessary load acting. 141386.doc 201102494 The gears on the drive side and the fixed side make the yaw swivel move smoothly. Therefore, a wind power generator having a slewing type of a slewing bearing using a sliding bearing can be provided, and the rotation of the nacelle can achieve a remarkable effect of reliability and durability.

A plurality of (e.g., three) windmill rotating blades 5 are radially mounted on the rotor 4 around its axis of rotation. Thereby, the wind from the rotation axis of the rotor head 4 to the windmill red rotor blade 5 is converted into the power for rotating the rotor head 4 about the rotation axis. <First Embodiment> The wind power generator 月 具备 具备 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 丨 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋 旋Rotary device 10A. The yaw apparatus 10A is rotatably supported by the nacelle 3' provided at the upper end portion of the tower 2, so that the yaw bearing 30 which mainly receives the moment load at the plane portion is provided. The sliding bearing 3G is not shown, and the horizontal sliding bearing material (hereinafter referred to as horizontal bearing material) 33 and the rotating body 34 are placed in a nacelle fixed to the upper end of the 141386.doc 201102494 tower 2 The turning portion 31 of the base member (cabin platen) u on the 3 side is fixed to the fixing portion 32 fixed to the side of the stationary tower 2.

In this case, the center position of the shaft of the turning portion 3 1 is the center position of the turning shaft of the casing 3, and is attached so as to coincide with the center position of the shaft of the Han 2 . Further, the turning portion may be a ring member of the body or a ring member which is divided into plural in the circumferential direction. The fixing portion 32 is a flange portion formed horizontally from the cylindrical member of the unit fixed to the upper end portion of the tower 2 to the inner side of the tower 2. The fixing portion (the flange portion forms a sliding bearing because the upper and lower flat portions come into contact with the horizontal bearing member 33, so that the processing for reducing the friction coefficient has been performed. Further, the symbol 2b in the figure is the tower body. The material 33 is fixedly attached to the lower inner surface of the rotating portion 3i, that is, a plate-shaped member such as a resin formed on a flat portion (opposing surface) on the inner side below the lip-shaped cross section. In the illustrated configuration example, the horizontal bearing material is used. The circumferential direction of 33 is divided into 12 pieces having a substantially trapezoidal shape, and each of them is arranged at equal intervals in the circumferential direction. Further, the number of divisions of the horizontal bearing member 33 is not limited to Μ, and the arrangement thereof is not necessarily equidistant 'only # is relative The total load area ' of the divided horizontal bearing members 33' may be appropriately adjusted according to the axial load acting on the swaying sliding bearing 3G. For the rotator 34', for example, a cylindrical shape or the like is used. The rotating body 34 is formed by a curved surface portion such as a cylindrical side surface and a vertical surface of the inner peripheral side of the fixed portion η. The vertical direction is held in the vertical portion in the rotating portion 3i. 141386.doc 201102494 Further, the rotating body 34 is not limited to a cylindrical roller, such as a cylindrical roller or a steel ball, as long as it has a radial direction which is reduced in the sliding bearing. The function of the gap is as follows. The yaw turning device 1A having the slewing bearing 30 is provided with a fixed gear 13A formed on the outer circumferential surface of the cylindrical member 2a fixed to the tower 2 side; The drive gear 15 that is fixed to the base member u of the base member u on the nacelle 3 side is rotated.

In the middle, due to the use of the swaying sliding bearing, the frictional force is increased back to the Korean and Japanese, and the rotation (4) is reduced. Therefore, the four sets of yaw horses and the drive gear 15 are arranged at equal intervals to increase the motor output. The number of the yaw motor 14 is not limited Here. ^ God Zaochuan's yaw slewing device 10 Α, can also be added to the motor (four) to increase the friction, and increase::::: force ... this, partial - two = (Figure 10B - go "to make The brakes required to stop the rotation of the nacelle 3 are "chemical: = Γ 16 and brake 塾 17, etc.", which contributes to the reduction of the plant cost. Moreover, the star circuit is not required due to the action of the brake mechanism, so it can be reduced. : Singularized β ϋ s and valves, and the yaw turning device of the wind power generator i as described above is mainly provided with a support surface and a turn 邛 3 1 disposed above the flange formed on the fixed portion 32. The sliding member 33 receives the moment load between the sliding member 33 and the rotating body 34 disposed between the fixed portion 32 of the slanting sliding bearing 30 and the rotating portion 31 to receive the load in the radial direction, so that the sliding bearing and the rolling bearing can be effectively utilized. The advantage is that the gap in the radial direction generated in the slanting sliding bearing 3 减小 is reduced. In other words, the slidable sliding bearing 3 〇 is subjected to the load in the radial direction by the rotator 34. Therefore, the inner peripheral end portion and the rotator 34 as the flange portion of the fixed portion 32 are the same as the rolling bearing. The gap between them can be set to 〇 or negative. In the case where the slidable bearing 30 is biased, since the rotator 34 receives the load in the radial direction, the gap formed between the fixed portion 32 and the rotator 34 can be reduced to none. <Second Embodiment> Next, a second embodiment will be described with reference to Figs. 3A to 6B of the wind power generator of the present invention.

Further, in the example of the configuration of the figure, the spring bearing material 30 is provided with a spring yellow pre-compression mechanism 50 in the horizontal bearing material 33 on the lower side. The bombing box 厌 address _-, the checking mechanism 50 can be used as the magazine 51 by using, for example, a screw magazine or a r 141386.doc 201102494 disc spring, etc. 'The spring constant of the spring 51 can be made according to the tightening amount of the nut 52. The adjustment has a function of changing the surface pressure of the horizontal bearing member 33 in contact with the fixing portion 32. Further, the spring preloading mechanism 5〇 may be appropriately employed as needed. However, it is preferable to provide the gap adjusting mechanism 6A with respect to the above-described roller follower 4, for example, as shown in Figs. 5A and 5B and Figs. 6A and 6B. The gap adjusting mechanism 60 is provided with a holder 61 that holds the cross-sectional shape of the roller follower 4, supports the adjusting bolt 62 of the holder 61 at one end, and is screwed to the other end side of the adjusting bolt 62. The nut 63 is formed. Further, in the configuration example shown in the figure, the nut 63 is double, but is not limited thereto. Since the gap adjusting mechanism 60 is provided, the amount of protrusion of the roller follower 4 can be adjusted by changing the screwing position of the nut 63 with respect to the adjusting bolt 62. The amount of protrusion adjusted here is such that the gap formed between the sliding surface of the roller follower 4A and the vertical surface of the inner peripheral side of the fixed portion 32 is changed. Therefore, the slewing bearing unit 31A including the gap adjusting mechanism 60 can widen the tolerance of the set gap at the time of manufacture, and can be optimally adjusted in the field after the assembly is completed. Further, the gap adjusting mechanism 60 described above can easily adjust the gap even when the partial sliding bearing unit 3A is replaced in the field when the slanting sliding bearing 3〇α is damaged. <Third Embodiment> Hereinafter, a third embodiment of the wind power generator of the present invention will be described based on Fig. 7 . Incidentally, the same portions as those of the above-described embodiment are denoted by the same reference numerals 141386.doc -12·201102494, and detailed description thereof will be omitted. In the towel of the present embodiment, a one-piece structure of %35, 36 connecting the upper and lower pairs of "sliding bearings" is used. The glyph rings 35, 36' are substantially connected by the upper portion. The ring 35 is formed in a substantially rectangular cross section disposed at the lower portion, and is integrally formed as a ring member having a "transformed portion (10) of a "shaped cross section". When the door ring structure is 36-shaped, it is incorporated by the (four) ring member 35 to hold the rotating body 34. The material 33 is connected to the upper and lower ring members 35 and 36, and is fixed to each of the opposing faces in advance. Thus, the number of parts for on-site handling and on-site assembly can be reduced by using a slewing type bearing having a ring shape in which the turning portion 31B is integrated and incorporating the horizontal bearing member 33 and the rotating body 34. Therefore, the setting of the working time at the time of installation and the gap between the sliding surface formed on the rotating body μ and the vertical surface on the inner peripheral side of the fixing portion 32 can be appropriately adjusted in a factory having sufficient equipment. <Fourth Embodiment> Hereinafter, a fourth embodiment of the wind power generator of the present invention will be described with reference to Figs. 8 and 9 . The same portions as those of the above-described embodiments are denoted by the same reference numerals, and their detailed descriptions are omitted. In the embodiment shown in Fig. 8, a slanting sliding bearing 3C is provided, which is formed as a τ-shaped cross section as a flange of the fixing portion 32A and on the inner peripheral side of the fixing portion 32A. The outer peripheral side is formed by forming an upper and lower support surface. 141386.doc -13- 201102494, that is, the fixed portion 3 2 A of the yoke form, from the upper end portion of the tower 2, specifically from the cylindrical member 2a of the unit fixed to the upper end portion of the tower body 2b, A flange portion formed horizontally on the inner side and the outer side of the tower 2. The fixing portion (the flange portion) 32 is in contact with the horizontal bearing member fixed to the turning portion 31 in the upper and lower plane portions to form a sliding bearing. Further, the sliding bearing 30 is not biased (: the rotating body 34 is used) The inner peripheral side and the outer peripheral side of the fixed portion 32 of the zi-shape are disposed in contact with the end surface of the flange portion. However, the rotor 34 may be disposed only on one of the inner peripheral end surface and the outer peripheral end surface. The configuration can reduce the gap in the radial direction. The swaying sliding bearing 3〇c thus increases the rigidity of the fixing portion 32 as a τ-shaped cross section as compared with the fixed portion 32 of the cantilever beam described above, thereby suppressing The bending of the swaying bearing structure caused by the load of the moment load, that is, the slewing slewing device of the nacelle 3 can be smoothly rotated, or the fixing portion 32A of the τ-shaped section can be miniaturized to ensure the cantilever beam The fixing portion 32 has the same degree of rigidity. Further, in the modification of the embodiment shown in Fig. 9, the position of the rotating body 34 is disposed from the inner peripheral side end surface and the outer circumference of the fixing portion 32 which is a τ-shape. The position of the side end contact changes The position is in contact with the inner circumferential surface and the outer circumferential surface of the tower 2 of the fixed support fixing portion 32. In this case, the rotor 34 is disposed inside the rotor housing portion 37 of the ring member 36 formed on the lower side. In the swaying sliding bearings 3〇c and 30C having the U-shaped fixing portion 32Α, the rotating body 34 is disposed on at least one of the inner circumferential side and the outer circumferential side so as to be in contact with the fixing portion 32A. The position in the up-and-down direction may be a position in contact with the end surface of the flange portion, or a position in contact with the wall surface 141386.doc •14· 201102494 of the tower 2. In the example of the configuration of the tower, it is within the tower 2 The rotor 34 is disposed on the circumference side and the outer circumference side, but may be disposed in only one of the configurations. Thus, according to the present invention described above, a sliding bearing that favors a slewing slewing bearing that is increasingly large is used, and is utilized. The rotor 34 defines a gap in the radial direction to constitute a gap, so that the gap in the radial direction can be reduced to reduce the offset of the shaft. Therefore, it is possible to prevent the excess load from acting on the gears of the fixed gear 21 and the drive gear 24, Skewed slewing device 1〇A Therefore, the wind power generator 具备 including the slewing device 10A that uses the sliding bearing on the slewing bearing has a smooth rotation of the nacelle 3, thereby improving reliability and durability. The present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the spirit and scope of the invention.
