Abstract

PURPOSE:To prevent torque from not being transmitted, by providing a pushing body having a configuration memory effect. CONSTITUTION:When a pushing body 7l is heated by a burner or the like, the pushing body 7l is inclined to restore its original configuration. On the other hand, since a third roller 7j is brought in contact with an outer ring 7d, a pressing force is produced between the third roller 7j and the outer ring 7d, and a pressing force is also produced between a second roller 7e and a first roller 7c so that the torque can be transmitted. If the rolling surfaces of the rollers 7j, 7e, 7c, etc. are abraded, since a force is present at all times in the pushing body 7l such that it is inclined to restore its original configuration, the pressing force would not decrease.

Transmission of the torque of this reducer (7) is achieved by friction due to the pressure contact force between the 10th-ra (7CH + 20th-ra (]e) and the outer ring (7d) under the intervention of friction-enhancing oil. Normally, the pressure contact force is applied by an "interference fit" such as cooling the input shaft (6a), but a cooling device is required to cool the input shaft (6a) when assembling the reducer (force). Further, it requires waiting time for cooling, and the assembly work is troublesome.

In addition, if this reducer is operated for a long time, the transfer surfaces of the first roller (7 (!)), the 20th roller (7e), and the outer ring (7d) will wear out. This invention aims to improve the above-mentioned problems, and is made of a material with shape memory effect. By providing a suppressor that presses the 20th roller toward the 10th roller, it is possible to prevent the inability to transmit torque due to a reduction in the pressing force between the rollers, and to expect smooth power transmission over a long period of time. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 5 to 9.

As shown in FIG. 7, the suppressor (71) initially
The outer circumference of 0-ra (7j) is aligned with the inner circumference line (7
da). Next, as shown in FIG. 8 during assembly, if the suppressor (71) is deformed, a gap will be created between the outer ring (7d) and the 30th ring (7j), allowing easy assembly. The suppressor in the state shown in Figure 8 (
'71) is heated with a burner or the like, the pressing body (71) tries to return to its initial shape. However, the 30th-La (7
Since the outer ring (7d) comes into contact with the suppressor (71), the shape of the suppressor (71) does not return completely as shown in FIG. Therefore, a pressure contact force is generated between the 30th ring (7j) and the outer ring (1d), and the 20th ring (7e) and the 10th ring (7C
) is also applied, making it possible to transmit torque. Also, outer ring (7d) I each roller (', + ) + (T
Even if the transfer surfaces such as le) and ('lc) are worn, a force that tries to return to the initial shape is always acting on the suppressor (71), so the pressure contact force decreases in accordance with the amount of wear. This does not occur, and stable torque transmission is possible.

As explained above, in this invention, the 10th roller is connected to the input shaft to which the hoisting motor of the elevator is connected, and the 20th roller is connected to the output shaft to which the drive sheave is connected, and these rollers are connected to each other. At the same time, the 20th-ra is always connected to the 10th-
This allows the suppressor to be deformed during assembly, eliminating the need for a cooling device and simplifying assembly work. Also,
Since a pressing force is generated after assembly, it is possible to prevent the inability to transmit torque due to a decrease in the pressing force between the rows 2, and to continue smooth power transmission for a long period of time.
