Abstract

The invention belongs to the technical field of machinery, and particularly relates to a composite gear. According to the composite gear, the technical problems that the prior art is not reasonable and the like are solved. The composite gear comprises a gear body, wherein the gear body comprises a bevel gear and a circular gear; the bevel gear and the circular gear are connected into an integratedstructure; the composite gear is characterized in that a wear-resistant body is fixedly connected to the inner annular surface of a central shaft hole of the gear body; an annular oil guide groove isformed in the central shaft hole; a plurality of oil inlet holes communicating with the annular oil guide groove and are formed in the outer peripheral surface of the gear body; and the wear-resistant body is provided with a plurality of oil outlet holes communicating with the annular oil guide groove. Compared with the prior art, the composite gear has the advantages that the design is reasonable, the structure is simple, the oil inlet rate is high, the lubricating effect is good, the friction coefficient is reduced, the wear resistance is achieved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a composite gear. Background technique [0002] Gears are a common mechanical part with various structural forms, such as spur gears, helical gears, bevel gears, worms, etc., and are widely used in various fields of production and life. As we all know, the gear is an important part of the transmission device, and it needs high installation accuracy and good alignment during installation. However, common gears have problems such as inconvenient installation, easy wear, low degree of coincidence, and poor installation accuracy. [0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. For example, the Chinese patent document discloses a gear [Application No.: 200720159453.4], which includes a gear shaft and a key, and is characterized in that a plurality of spur gear pieces are mou...
