Some More Particular Knowledge of Bevel Gears

Bevel gears are used for transmissions between intersecting axes. Generally, the single-stage transmission ratio can be up to 6, the maximum could reach 8 or above. Corresponding transmission efficiency could be up to 0.94~0.98.

As designing, manufacturing and installing works of straight bevel gears and helical ones are more simple, added loud noises made by the 2 kinds bevel gears, they’re commonly adopted in low speed transmission units (<5m/s). The transmission power of bevel gears can reach 370Kw, and the peripheral speed can be around 5m/s. Helical bevel gears have stable transmissions but have high gear loading capacities. Therefore, bevel gears are commonly applied in the conditions of high speed and heavy load in accordance with their special characteristics. In addition, bevel gears occupy an important position in auto industry.

Applications
In vehicle manufacturing, bevel gears contain the following applications:

I. Deliver the driving force from engines to the wheels through gear boxes and main driver;

II. Alter the direction of rotational motion created by engines with longitudinal configurations so that the wheels can obtain rotational motion in accord with its driving direction;

III. Reduce the rotary speed created by engines for increasing the torque from engines and further urging the wheels to achieve sufficient pulling force.
