With reference to accompanying drawing, with transparent view winch of the present invention is described, and part has been disassembled for ease of explanation.Winch 10 is described as follows.
Winch 10 comprises firm banking 12 and center shaft 14 fixed thereon.Reel 16 is installed on the base 12, and its profile can be received work hawser wound thereon.With the handle shown in the imaginary line 18 among the figure reel is rotated.The no ratchet assembly of explanation winch of the present invention, reel rotate and anti-reverse braking maneuver now.
Refer again to Fig. 1, as seen power-transfer clutch 20 and following power-transfer clutch 22 on two-unidirectional roller double curved surface type, such power-transfer clutch is that the application number of submitting on February 18th, 1987 is 016,458, the name that awaits the reply patent and submit simultaneously that name is called " improved power-transfer clutch " is called to have in the continuous application of " improved power-transfer clutch " narrates and has proposed claim, and these two application cases are the combined cost application case part now.This improved clutch designs one-tenth is provided at a direction upper surface-roller-surface and is meshing with each other and freely rotates between inner ring on the other direction and outer ring.One group of power-transfer clutch like this, as shown in Figure 1 has a common rotating shaft line.
As a claim of narrating and proposing in the above-mentioned application of awaiting the reply, this power-transfer clutch has bi-curved inner ring of circular cone and outer ring, can mark the straight line bus by the every bit on it can be cylindrical or cylindrical-conical roller, its profile the and highly straight edge line of hyperbolic surface is respective angles relation, to realize blocking or the grasp rotation engagement force that is used for providing free-wheel clutch, be delivered to the outer ring from inner ring by roller.Particularly, these rollers also provide the rolling bearing between inner ring and the outer ring, to realize steadily and noiseless running.Because roller is running continuously in the winch working process, its effective area of contact constantly changes, the breakage problem that stress concentration and fatigue etc. produce so the undue wear of arbitrary part of roller can not cause.
Under this environment, last power-transfer clutch 20 is mounted on the direction of the running surface 17 rolling work hawsers of reel 16 and meshes, and also freely rotates and play rolling bearing on other direction, so just needs antifriction-bearing box.On the other hand, the engagement that provides between surface-roller-surface is provided following power-transfer clutch 22, and plays brake action in the direction opposite with the hawser coiling direction, so that maintain the hawser of winding.
Referring to accompanying drawing, visible power-transfer clutch 20 comprises inner ring 21 again, and a drive element 19 is arranged at its top, is used for assembling suitable driving handle 18 or drives the wrench (not shown).The inner ring 21 of power-transfer clutch 20 has a circular cone double curved surface surface 24, is the running surface of power-transfer clutch inner ring; Corresponding outer ring circular cone double curved surface surface 26 then is that the upper inner surface by reel 16 constitutes.The surface of last power-transfer clutch 20 by the bottom than major diameter and determining on top than minor diameter.The roller 28 of many transmission thrusts places between the running surface.With regard to upper clutch 20, facing surfaces 24 does to transmit contacting of thrust with 26 with roller 28, make the direction running of reel 16 to the rolling hawser, and Lu's an official document or note lifts 2 roller " contact of back transfer thrust " (under the braking contact situation) that provide is provided in the opposite direction, and the position of locking maintenance around the reel of upper cable is provided like this.
As mentioned above, the circular cone double curved surface surface of following power-transfer clutch 22 is positioned at the position of the same power-transfer clutch 20 position opposite.Following power-transfer clutch 22 rotates going up freely in the opposite direction with hawser rolling side, reel is rotated flexibly in that this side up, but the brake action of power-transfer clutch 22 keeps the reel position to prevent the hawser unwinding down.In fact the roller of being made by good bearing steel 28 provides rolling bearing, so just can be with roller or ball-bearing casing, thus reel is able to steadily, silent operation, does not need special antifriction-bearing box, ratchet or like fully.In addition, roller is preferably columniform and have round section, but if desired, also cylindrical-conical, its termination is preferably arc as shown in the figure.
Following power-transfer clutch 22 is with the same power-transfer clutch 20 the same structure and principles running, female cone double curved surface surface 30, outer cone double curved surface surface 34 wherein arranged and place therebetween " braking " roller 34.But in this case, visible roller and in same plane on the roller bevel relative status of power-transfer clutch 20; Like this, their pinning hand of rotation or the contact that claims surface-roller-surface are just opposite with last power-transfer clutch 20.
See the practical structures of Fig. 1 again in conjunction with Fig. 3.Firm banking 12 has an annular stepped part 13 that annulus 36 is housed on it, annulus 36 preferably adopts the self-lubricating material of graphite-filled polyamide fibre and so on, it is equivalent to plain bearing between step portion 13 and roller 34, and to not only playing supporting role around axis own but also around the roller of winch axis rotation.This in fact the annulus of self-lubricating be to trackslip with respect to the step portion 13 of outer reel and base 12, act on the surface that intrinsic downward component on the roller 34 makes roller contact and damage step portion 13 when preventing application of load with this.Graphite-filled polyamide fibre annulus preferably has many arc pits, or the spill annular groove is as shown in Figure 3 with the termination that holds each roller with make each roller keep suitable spacing.Another kind method, roller can have another kind of termination shape, and (for example flat and without arc), graphite-filled polyamide fibre annulus is made corresponding shape supporting roller 34.Graphite-filled polyamide fibre annulus 40 is positioned at the top of the roller 28 of power-transfer clutch 20, with supporting roller opposing since the inside engagement between roller and the surface 24 and 26 produce act on the component that makes progress on the roller.Equally, graphite-filled polyamide fibre annulus 42 between last power-transfer clutch 20 and following power-transfer clutch 22 as the bearing between center shaft 14 and the reel 16, roller 28 and following roller 34 are gone up in supporting simultaneously, but, since roller be arrange with opposite angle and oriented mutually opposite direction on the trend of moving, try hard to leave graphite-filled polyamide fibre annulus 42, so do not need to make pit on this annulus.
Further referring to accompanying drawing, flange 44 is positioned at the bottom of winch, and is fixed on screw thread 46 on the corresponding screw thread of reel bottom.Clamp ring 48 be positioned at flange 44 above, having self-lubricating graphite to fill polyamide fibre disk 50 and 52 respectively between graphic locking lasso 48 and the flange 44 and between clamp ring 48 and the reel 16.On reel 16, the most handy holding screw as shown in Figure 3 is screwed into by the aperture in the clamp ring 48 54 flange 44 by suitable fastener locking.Equally, clamp ring 48 usefulness are pressed into set pin 56 and are fixed on the base 12.Whole device tightens together with jam nut 58, jam nut is screwed in reel 16 tops between the last drive part of inner ring 21 of reel and last power-transfer clutch 20, so just can to comprise top inner ring 21, graphite-filled polyamide fibre annulus 40, go up roller 28, graphite-filled polyamide fibre annulus 42, roller 34, graphite-filled polyamide fibre annulus 36 and chassis 12 optionally apply the downward thrust of giving in advance down.
The assembly method of lower member is described now.Referring to Fig. 1 and Fig. 3, have on the base 12 one radially circular hole 60 reach in the hole 62, hole 62 is enough to hold pin 56 in the demolition process.Upright opening 64 is upward through base with hole 60 direction that meets at right angles, and with the winch parallel axes.Flange 44 same porose 66 is with 64 combinations of the hole on the base 12, and remains a straight line in assembling, also will further specify below this point.Clamp ring 48 have one radially circular hole 68 in order to holding the pin 56 that is fixed with pressure in the hole 60 that is pressed into base 12, to keep as shown in the figure the tram of clamp ring 48 with respect to base 12.Flange 44 also has a tapped bore 72, matches with the corresponding tapped bore 74 of reel 16 bottoms and holds as shown in Figure 3 holding screw 76.
From base shown in Figure 1 12, flange 44 is loaded on the axle 14, and the hole 64 on the bases 12 is aimed in its hole 66, and temporarily with pin or for example the instrument of screwdriver and so on fix.Then a graphite-filled polyamide ring 50 is positioned on the flange 44, again clamp ring 48 is positioned on the graphite-filled polyamide ring 50.Pin 56 is press-fit in the opening 60 of the opening 68 of clamp ring 48 and base 12, keeps the relative position of these two parts, then, places graphite-filled polyamide ring 52 on the clamp ring 48 and makes reel 16 location.Screw thread 78 is meshed with corresponding screw thread 46 on the flange 44, by selling or other ccasual instruments insert as shown in the figure holes 64 of aiming at hole 66, flange 44 can be remained on counterrotating position with respect to base 12.Will be understood that when reel 16 rotates, the screw thread 78 on the reel will further screw with the corresponding screw thread of flange 44, flange will be lifted to the appropriate location, thereby make flange 44 remain on a fixed position.When reel is last when screwing with flange 44, reel forwards to and approaches to make obviously those enough tight positions of alignings, hole 72 and 74 most.After this,, thereby make screw thread 76 further turn to such position, even flange 44 remains on fixing and locked position with respect to reel 16 with the tool insert hole 54 of for example screwdriver and so on.At this moment, just no longer needed, therefore can take out thereby temporarily flange is fixed in the pin or the instrument that make hole 64 and 66 remain in alignment on the base 12.Very clear, can find that the weight of reel is supported fifty-fifty by roller 34 and clamp ring 48.
Finish after the above-mentioned steps, graphite-filled polyamide ring 42 is set on the axle 14, then, it is temporarily fixing that the inner hyperboloid clamping ring 21 that will have a roller 28 is coated the lubricating oil of suitable weight, and graphite-filled polyamide ring 40 is installed at an upper portion thereof.After inner ring 21 insertions, with the screw thread and screw thread 80 engagements of jam nut 58.With with above-mentioned opposite step, winch can be dismantled.Should be noted that by selling 56 to push away inwardly, withdraw from hole 62 at last, pin 56 can be taken out, thereby they are dismantled up to its disengaging hole 68 and 66.
Can see, the winch described in Fig. 1 and Fig. 3 can with one for example the instrument of standard winch handle 18 and so on rotate, handle 18 has the drive end 19 of respective shapes opening of inner ring 21 central authorities of an insertion upper clutch 20.Such drive end can be square or hexagon or any desirable shape.Winch can be selected first predetermined direction rotation corresponding to the transmission direction of upper end power-transfer clutch 20, thereby rotatablely moving of handle 18 passed to the inner ring 21 of upper clutch 20 by drive end 19, and will rotatablely move by inner hyperboloid conical surface 24, outer hyperboloid conical surface 26 and the roller between them 28 thus and be delivered to reel 16.Along with hawser on the outer running surface 17 of reel, the position of rotation that reel reaches is thus kept by the plugging effect of bottom power-transfer clutch 22, and the operative orientation of bottom power-transfer clutch 22 or braking direction are opposite with the operative orientation of upper clutch 20.Like this, along with handle rotates a few as required continuously, first direction is a coiling direction, and when the hawser position on the running surface 17 that is wound on reel 16 kept, handle was freely on the opposite sense of operative orientation.According to present embodiment, emitting of hawser must rely on manual finishing, and freely do not rotate because this embodiment does not have have among the embodiment shown in the Figure 4 and 5 and that will be described hereinafter the sort of reverse.
