Elevator Industry

The function of the elevator is to convert the electrical power at the beginning that runs the motor, to mechanical power, that is used by the system. An elevator comprises a motor and, at common worm gear reducer system. The gears has played a vital role in the development of elevator technologies. The development of sophisticated worm and helical gears is a significant achievement in the field of elevator industry.

Gears are employed in the elevators with middle and low speed for having an effective check on the revolution of motors before a supply is made to the rope sheave. Gears are considered an integral component of low speed elevators.


Worm and helical gears play a crucial role in the functioning of the elevators. Together they are called as the reduction gears. The power transmission efficiency of helical gears are higher as compared to worm gears by around 30%. But in the elevator industry preference is given to the worm gears. This is due to the difficulty in machining a helical gear. In the elevator industry unless there is proper machining of gears noises and vibrations can take place.

The elevators using helical gears are operated with a considerable reduction in energy in contrast to elevators working with worm gears.
