Description

A rear axle drive bevel gear

technical field

The utility model relates to the technical field of gears, in particular to a rear axle driving bevel gear.

Background technique

Bevel gears are used to transmit motion and power between two intersecting shafts. In general machinery, the angle of intersection between the two shafts of bevel gears is equal to 90° (but may not be equal to 90°). Similar to cylindrical gears, bevel gears have index cones, tip cones, root cones and base cones. The cone has a big end and a small end, and the circles corresponding to the big end are called the index circle (its radius is r), the addendum circle, the tooth root circle and the base circle, respectively. The movement of a pair of bevel gears is equivalent to the pure rolling of a pair of pitch cones. The formation of the tooth profile of bevel gears is similar to that of cylindrical gears. The difference is that the base cylinder is replaced by the base cone. As shown in the figure on the right, the occurrence surface S is tangent to the base conic generatrix. When the generating surface S does pure rolling along the base cone, any straight line OK on the generating surface contacting the generatrix ON of the base cone will form an involute curved surface in space. This surface is the tooth profile surface of the spur bevel gear. The trajectory of each point on the straight line OK is an involute (the involute at the vertex O is a point). Each point on the involute NK is 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.

The existing bevel gear is usually set as an integral structure. When a certain rack is damaged, the bevel gear needs to be replaced as a whole, resulting in a lot of waste, and the connection between the traditional bevel gear and the transmission shaft of the automobile is complicated, and the connection process is relatively It is troublesome, wastes a lot of installation time, and makes the work less efficient.

In view of this, we propose a rear axle drive bevel gear.
