Novel noise-reduction type bevel gear and manufacturing method thereof

Abstract

The invention discloses a novel noise-reduction type bevel gear and a manufacturing method thereof. The novel noise-reduction type bevel gear comprises a tooth disc, tooth frames, tooth assemblies, alimiting assembly, a tooth holder, a connecting shaft and a pressurizing assembly. The multiple tooth frames are installed on the circumferential surface of the tooth disc in an annular matrix array mode, and the tooth assemblies are installed in the tooth frames. The tooth holder is arranged at the bottom of the tooth disc, the limiting assembly is arranged between the tooth disc and the tooth holder, and the connecting shaft is welded to the bottom of the tooth holder. A piston can be pushed and extruded by rotating a lead screw. After pushing and extruding, pressure liquid is pushed into rod holes through communicating holes, limiting rods can be pulled in the rod holes, pushing and lifting of the tooth disc can be achieved, it is guaranteed that the tooth disc is better attached to thesurface of another gear in the meshing process, the gap between gears is reduced, delay can be reduced, collision of the gears during meshing transmission is reduced, noise of gear meshing transmission is reduced, and a better using effect is achieved.

Description

technical field [0001] The invention relates to the field of gears, in particular to a novel noise-reducing bevel gear and a preparation method thereof. Background technique [0002] Bevel gears, also called bevel gears, are widely used in industrial transmission equipment, vehicle differentials, locomotives, ships, power plants, steel mills, railway track inspections, etc.; [0003] Existing gears are widely used in mechanical equipment, but during the use of gears, noise will be generated due to the vibration of the gear itself and the friction between the mechanical parts. Sometimes it is necessary to have certain requirements on the noise. , and the gears are not completely rigid, the surface fit of the gears is not good during the meshing process, so meshing noise will be generated during the meshing process of the gears, and the gears will generate knocking noise due to the backlash in the meshing process of the two teeth.

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of noise-reducing bevel gear and its preparation method, which solves the problem that during the meshing process, the surface fit of the gears is not good, so meshing noise will be generated during the meshing process of the gears. There is a technical problem with backlash, which causes the gears to make rattling noises
