A WORM-GEAR-TYPE SPEED REDUCTION DEVICE FOR AN ELEVATOR

摘要

An elevator including a worm-gear-type speed reduction device which comprises a worm and a worm wheel, said device further including a resilient member for receiving a thrust load on the worm whereby the misalignment of the gearing engagement between the worm and the worm wheel is converted into an axial displacement of the worm shaft and absorbed by said resilient member so that a vibration and noises of a cage caused by a fluctuation of rotation in the wheel shaft are prevented.
