Advantages of worm gear drive

Compared with bevel gear drive, worm gear drive has the following advantages:

(1) In the case of small outline size and structure mass, the results show that

Large transmission ratio (can be greater than 7).

(2) It can work smoothly and noiseless at any speed.

(3) It is convenient for the general layout of the car and the layout of the through multi axle drive.

(4) It can transmit large load and has long service life.

(5) Simple structure, convenient disassembly and adjustment.

However, the worm gear ring needs to be made of high-quality tin bronze, so the cost is high; in addition, the transmission efficiency is low.

Worm drive is mainly used in the production of a small number of individual heavy-duty multi axle drive vehicles and buses with high-speed engines.
