What is a Bevel Gear?
A bevel gear is a gear which is designed to connect with a gear mounted on an axis which may be positioned at any number of angles. Classically, bevel gears are used at 90 degree angles to each other, although other types of angles may be used as well. This is by contrast with other types of gears, which must generally be used either parallel to each other, or at right angles, in some specialized cases. Bevel gears are used in a number of applications, including the differential gear of a car. As the term “bevel” would suggest, the face of a bevel gear is angled. Typically, a bevel gear is conical in shape, with the teeth running along the side of the cone, and the angle of the sides can be varied, depending on the application for the gear. The beveled design allows the gear to intermesh with another bevel gear at several different angles, depending on how it has been machined. In a straight bevel gear, the teeth are straight, running vertically along the cone. The problem with straigh
