The bevel gear should generally be referred to as a bevel gear. Spur gears and helical gears are the difference in tooth profile. The spur gear tooth shape is parallel to the gear shaft, and the helical gear tooth shape is at an angle to the gear shaft. When the helical gear meshes, the degree of coincidence is better, and it is more suitable for occasions with large load and low speed. Low-speed transmissions are usually spur gears if the load is not large. The cost is lower. Gear: A gear is a mechanical component that has teeth on the rim that can continuously mesh to transmit motion and power. It is a toothed mechanical part that can mesh with each other. The diameter of the large gear is twice the diameter of the pinion.
A spiral bevel gear is a type of bevel gear.
Spiral bevel gears can be divided into: zero-degree spiral bevel gears and double-contracting teeth and spiral bevel gears, etc.
