spur gear

Spur gears are a type of cylindrical equipment, with shafts that are parallel and coplanar, and tooth that are directly and oriented parallel to the shafts. They’re arguably the easiest and most common type of gear – simple to manufacture and ideal for an array of applications.

One’s teeth of a spur gear have got an involute profile and mesh one tooth at a time. The involute form implies that spur gears only create radial forces (no axial forces), however the method of tooth meshing causes high stress on the gear tooth and high noise production. Due to this, spur gears are typically used for lower acceleration planetary gearbox applications, although they can be utilized at almost any speed.
