Traction machine reducer

The reducer is used on a geared traction machine. Installed between the traction motor shaft and the traction sheave shaft.

Types and characteristics of the reducer (box): The worm reducer consists of a worm with a drive shaft and a worm gear mounted on the housing bearing with a driven shaft. The speed ratio can be in the range of 18 to 120, and the number of teeth of the worm gear Not less than 30, its efficiency is not as good as that of a gear reducer, but its compact structure and small size.

Characteristics of the worm reducer: large transmission ratio, low noise, stable transmission, and when the worm gear is driven by the worm wheel, the reverse efficiency is low and there is a certain self-locking ability; the elevator braking torque can be increased, and the safety when the elevator is parked is increased.
