Description

Technical Field

[0001] The utility model relates to a polishing mechanism, in particular to a hole-type worm tooth surface polishing mechanism, belonging to the technical field of worm processing. Background Art

[0002] A worm is a gear with one or more spiral teeth that meshes with a worm wheel to form a staggered axis gear pair. Its pitch surface can be a cylindrical surface, a conical surface or a torus surface. There are four types: Archimedean worm, involute worm, normal straight worm, and conical envelope cylindrical worm. Worm transmission is composed of a worm and a worm wheel.

[0003] The processing of the worm requires polishing of the worm at the end. Polishing is a process commonly used in the worm manufacturing industry to improve the roughness of the worm tooth surface. It uses a soft polishing wheel to polish the surface of hard steel or copper worms. Without changing the accuracy of the worm, the roughness of the worm tooth surface can be further improved, thereby improving the transmission efficiency of the worm and reducing the meshing noise of the worm.

[0004] A special polishing machine for hole-type worm gear tooth surfaces disclosed in the Chinese patent application disclosure specification CN215998983U adopts a polishing motor to drive a polishing wheel to perform contact polishing on the worm gear. This solution solves the problem that the roughness of the worm gear tooth surfaces varies greatly due to manual polishing and is not suitable for mass production. It can ensure that the surface roughness of the worm gear after polishing has good consistency to meet the needs of mass production. However, since the angle adjustment of the polishing motor is not convenient, it is not convenient to adjust the polishing wheel according to the contact angle with the worm gear tooth surface, which makes the contact effect between the polishing wheel and the worm gear tooth surface poor, affecting the quality of polishing. At the same time, it is not convenient to adjust when polishing worm gears of different models, resulting in poor applicability. Utility Model Content
