Bevel gears are used to transmit motion and power between two intersecting axes, and their intersection angle may not necessarily be equal to 90 degrees. The shape of bevel gears is different from cylindrical gears, they have indexing cones, tooth tip cones, tooth root cones, and base cones. The large and small ends of these cones correspond to the indexing circle, tooth tip circle, tooth root circle, and base circle. The tooth profile of bevel gears is similar to that of cylindrical gears, except that a base cone is used instead of a base cylinder. When the generating surface S undergoes pure rolling along the base cone, any straight line OK that contacts the generatrix ON of the base cone on the generating surface will form an involute surface in space, which is the tooth profile surface of the spur bevel gear. The points on the involute NK are equidistant from the cone top O, so the involute must be on a spherical surface with the cone top O as the center and OK as the radius, that is, NK is a spherical involute.
Bevel gears and cylindrical gears are two commonly used types of gears in our machinery, which have different shapes and characteristics. I hope this video can help you better distinguish them.
