The teeth on China Air Compressor helical gears are trim at an angle to the face of the gear. When two tooth on a helical gear system engage, the get in touch with starts at one end of the tooth and gradually spreads as the gears rotate, before two teeth are completely engagement.

This gradual engagement makes helical gears operate a lot more smoothly and quietly than spur gears. For this reason, helical gears are found in virtually all car transmissions.

Because of the angle of one’s teeth on helical gears, they create a thrust load on the gear when they mesh. Devices that use helical gears have bearings that can support this thrust load.

One interesting thing about helical gears is that if the angles of the apparatus teeth are correct, they can be mounted on perpendicular shafts, adjusting the rotation angle by 90 degrees.
