Abstract

The invention discloses an anti-backlash gear device. The anti-backlash gear device comprises a main gear, an auxiliary gear, snap springs and flay hammers, wherein a plurality of radial sliding grooves are evenly distributed in the periphery of one side of a gear disk of the main gear, the radial sliding grooves are rounded rectangles, a hub extending outwards is arranged in the middle of the main gear, and snap spring grooves are formed in the peripheral side of the hub; a plurality of deflecting sliding grooves are evenly distributed in the periphery of one side of a gear disk of the auxiliary gear, the deflecting sliding grooves are rounded rectangles and are arranged corresponding to the radial sliding grooves of the main gear in a deflecting manner, a center hole is formed in the middle of the auxiliary gear and is arranged to be matched with the hub of the main gear in a sliding manner, and the radial sliding grooves and the deflecting sliding grooves of the auxiliary gear form buckling containing cavities; the snap springs are arranged in the snap spring grooves; and the fly hammers are cylindrical and are arranged in the buckling containing cavities in a sliding matched manner. According to the anti-backlash gear device, dislocation of the main gear and the auxiliary gear is achieved through the centrifugal force of the fly hammers, the gear backlash action is eliminated, a prepositioning screw is relieved, and the gears can be assembled in a complex cavity conveniently.

Description

technical field [0001] The invention relates to the field of engine transmission, in particular to an anti-backlash gear device. Background technique [0002] Anti-backlash gear unit is a common component device for high-efficiency engines. Anti-backlash gears are usually used in engine gear transmission to reduce motion noise. The common anti-backlash gear device has the circlip energy storage main and auxiliary gear dislocation type. The positioning screw is used to ensure the alignment of the main and auxiliary gear teeth. After meshing with the mating gear, the positioning screw is removed, and the circlip is clamped to achieve the misalignment of the main and auxiliary gear teeth, eliminating meshing The role of backlash. [0003] The circlip energy storage main and auxiliary gear dislocation anti-backlash gear device needs to disassemble the pre-positioning screw, and the structure is complicated, which makes it difficult to assemble the gear in the complex cavity. ...
