Helical gear andBevel gearThe distinction:

First, the nature is different: 1. Bevel gear: a gear used to transmit motion and power between two intersecting shafts.

2. Helical gear: reduction transmission device.

Second, the characteristics are different: 1. The characteristics of the bevel gear: the angle of intersection of the two shafts of the bevel gear is equal to 90 (but not necessarily equal to 90).

2. Helical gear features: small size, light weight, large transmission torque, smooth starting, fine transmission ratio classification, and can be connected and selected at various installation positions according to user requirements.

Helical gears are not complete helical gears.It should be said that the helical gear is the meshing method of two helical gears, which can be distinguished in different directions in space.ordinarySpur gearAt the same time, it meshes along the tooth width, which produces shock vibration noise and unstable transmission.Helical cylindrical gear transmission is better than straight-tooth cylindrical gear transmission, and uses a compact center distance when high-speed and heavy-duty.The formation of the tooth profile of the bevel gear is similar to that of the cylindrical gear, except that the bottom post is replaced by the bottom cone.The movement of a pair of bevel gears is equivalent to the pure rolling of a pair of pitch bevel gears.
