INSTRUCTION STATEMENT α) [Technical Field of the Invention] The present invention relates to an elevator roll which has a better female integrity and can be used in a "rod transmission mechanism, particularly a ball screw transmission mechanism; especially η tired# A mechanism that can still be inspected when an abnormality occurs. "A kind of pre-existing technology before the hazard occurs. [Prior Art] The development of the elevator has been designed with a transmission mechanism, and four designs such as cable and linear motor. Among them, the screw type transmission, due to the traditional screw type transmission, has a large frictional resistance of about 30%. The elevators that are standing in the energy need to have a relatively rapid temperature rise and power consumption for nearly a decade, due to the rolling The lower, slowly, only the opinions of the ladder organization. Ball screw force and excellent mechanical transmission effect The coefficient of the traditional sliding friction screw can be reduced from the traditional sliding friction. The disadvantage of the conventional sliding friction screw bead screw is that it has a history of more than one year, and the return mainly includes the screw type. At present, the most used mechanism is that although the transmission mechanism is used for a hundred years, the mechanical efficiency of the transmission is not angular, and the speed of the movement is not really high. Therefore, the development of the bead screw is becoming more and more feasible. The main advantage of the ball lever is its rate. Because the ball screw is sliding friction, the friction resistance screw is reduced from 0. 1 to 0. 〇〇2 is increased to 95% by 30% to the full extent. Compared with the traditional one, the elevator, the hydraulic type, and the steel type are steel cables. The history of use, the spiral of dynamic friction is only high; especially the current frictional resistance will be cooked, and the price of the screw applied to the friction of the small frictional steel ball is very low, its friction, and mechanical efficiency. However, the rolling friction screw is -1271378. 5. The invention description (2) is lower, because the traditional submersible is in the inside of a rigid material. The sliding nut of the screw is very simple, only because of its simple structure. Therefore, ρΓ & σ work a f-shaped cross-section of the female thread before the failure, A,, M = ship f will not be, and is born in the sliding nut, and convenient pre-command cap = first In the case of severe wear and tear, the mechanism for screwing is more complicated, and avoiding the occurrence of pre-existing. In contrast, the ball makes the steel ball circulation component, the inner bead nut will contain at least the steel ball, and even if the female thread is not yet clear; the three components such as the body of the body are regularly inspected and found in advance, so it is difficult to see by one of the elevators. That is 4 replacement or repair. Therefore, the use of the ball screw elevator; ^ force and mechanical efficiency and other issues, but 182 / can improve the friction resistance before the occurrence of difficult to check out, so ς = = doubt ‘and the fault has many problems, need to be revised. The ball screw drive mechanism of the ladder is still [invention] The main purpose of the invention is to achieve a small swing, high mechanical efficiency and high safety: 2: electricity, friction resistance: damage to the mechanism occurs, the elevator car heart: ::The sigma of the birth of the sigma machine The second purpose of the invention is to provide _ cat two with + = 'such that in case the ball nut is damaged, the bead snail drive or repair 1 free follow-up derivative damage: easy to detect Instant replacement 1271378 V. INSTRUCTION DESCRIPTION (3) In order to achieve the screw drive mechanism of the present invention, the frictional resistance problem of the ball screw of the elevator of the present invention using the ball screw is used. , two f, to improve the sliding friction for a hundred years as a hollow piece... diameter; and (; for the ball nut) there are balls, the female spiral groove and the thread 5 θ, H in the female spiral groove and the screw shaft There is no sliding friction between the two, and the rolling of the ball, so that the female screw is held relative to the screw shaft; 2 to reduce the efficiency of the ball nut. 〃卩力 and soaring the completeness of the transmission mechanism of the elevator, this issue: cited, the invention of the ball screw transmission mechanism of the elevator of this t-ming:, 'the inner diameter is provided with the screw f, in order to make this The spiral groove of the 螺旋 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Under the normal use of sliding, r; design, so that in the elevator car temple i negative: that is, the position of the epoch and the male spiral groove contact with | Spiral:: the inspection of the transmission mechanism of the screw 'The invention is set in the yang The gap between the mechanism and the male snail will change with the use of the mechanism: the distance between the gaps will also change accordingly. Therefore, the measuring screw can be used as early dimension = "the distance between the gaps between the gaps can be detected. And the elevator and the second, when the ball nut fails and can not bear the load of the elevator, the rotation is carried by the sliding nut, and the sliding nut is to withstand the eighth page of the elevator; That is, the screw and the snail i shape, and because of the electric ί: ·, it is convenient to detect the fault shape of the ball nut. * Carrying the elevator car, and avoiding the uneasiness of use: J machine see two ij - step To understand the features and technical contents of the present invention, please refer to Fig. 6: The drawings are only preferred embodiments and descriptions of 'however' and ♦ are used, and are not intended to impose any limitation on the present invention. - 4 beads = 3, sliding nut 4, connector 5: 2 = support beam 2, upper = floor 2 2 lock in elevator: ^...relative::;:=beam 2 moves on the carriage 6 of the elevator, and the carriage 6: 5 ' is connected to the empty part, The screw is arranged on the screw shaft:; in the screw 衮 = 3 is - two 'simultaneously moving along the axial direction of the screw sleeve, and the fixed rotation 5 ' to drive the car temple 6 to move along the axial direction of the screw shaft 2 linkage Up to 7 sets on the support beam 2, used to lift the 2 linkages 5.
