Bevel gear is a small part in helical gear, and its main function is to change
movement
direction and to do power change in different angles in accordance with different
bevels and helix angles.

Features of bevel gears:
1. Correct ratio, easy to change speed
2. Small space, large transmission power
3. Easy to lubricate, small wear and tear
4. Can transmit both high and low speed


Functions of bevel gears:
1. Change the speed of transmission power
2. Change the direction of transmission power
3. Transmit power
