Description

Technical Field

[0001] The utility model relates to the technical field of bearing polishing, in particular to a roller shaft surface polishing device. Background Art

[0002] Roller shaft surface polishing is an important machining process, primarily used to improve the surface quality of the roller shaft, reduce friction, and increase service life. Polishing the roller shaft surface offers several significant benefits. The smoother polished surface reduces friction with other components and reduces energy loss. A smooth surface produces less friction noise during operation, helping to improve the noise level of the equipment. The polished surface is more wear-resistant, reducing wear caused by friction and thus extending the roller shaft's service life. A smooth surface effectively reduces material adhesion, helping to reduce corrosion and rust. Polishing the roller shaft surface not only improves its performance and durability, but also helps optimize the overall performance and aesthetics of the equipment.

[0003] When polishing the roller shaft, since the roller shaft itself is made of metal, a large number of sparks will be generated during the friction of the metal, which will cause harm to the workers. The conventional polishing method is to place the roller shaft at the output end of the polishing equipment, which will not only cause harm but also have low stability, resulting in poor polishing effect. Therefore, a roller shaft surface polishing device with automatic water supply to reduce spark generation, installation of various lengths and sizes, and full polishing of the outer surface of the roller shaft is designed to solve the above problems.
