45# Steel Mechanical Transmission Spur Gear Cylindrical Gear

1. Spur gear is a type of cylindrical gear, often referred to as spur gear, which is mainly used in mechanical transmission. Its main feature is that the tooth line coincides with the central axis, and the tooth profile of the spur gear always remains straight with respect to the axis. Spur gears can rotate in both directions. In order to enable the gears to rotate in both directions, the tooth profiles on both sides of the gear teeth are composed of involute curved surfaces with the same shape and opposite directions.

2. The tooth surface of a spur gear is a straight line, so its tooth surface angle is zero degrees. The contact area of the tooth surface is relatively small, so the noise and axial load during transmission are also relatively large. In addition, the spur gear has a long tangential length of the tooth surface and a large force-bearing area, which can withstand greater loads, but is also more susceptible to wear.
