Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to an adjustable hanging tool for gear shot peening processing. Background Art

[0002] Shot peening of reducer gears is an effective surface strengthening process, and its main functions are reflected in the following aspects: 1) Improving surface hardness and wear resistance: Shot peening uses high-speed shot to hit the gear surface, causing plastic deformation of the surface material and generating residual compressive stress. This residual compressive stress can significantly increase the hardness of the gear surface and reduce the friction coefficient, thereby enhancing the wear resistance of the gear and extending its service life. 2) Improving fatigue resistance: The residual compressive stress layer formed by shot peening can effectively prevent or slow down the initiation and expansion of cracks caused by alternating loads, and significantly improve the fatigue resistance of the gear. This is especially important for reducer gears that are subjected to high stress cycles, and can significantly reduce the risk of fatigue fracture. 3) Improving the consistency of surface roughness: Shot peening helps to homogenize the micromorphology of the gear surface, improve the surface roughness, make it easier to form and maintain the lubricating oil film, thereby improving the lubrication effect and reducing friction and wear. 4) Enhance anti-bite and anti-bonding capabilities: Under heavy load or high-speed operation conditions, biting or bonding is prone to occur between gears. The gear surface after shot peening is rougher, which can form a tiny oil storage space, which is conducive to the storage and distribution of lubricating oil, thereby improving the gear's anti-bite and anti-adhesion capabilities. 5) Optimize stress distribution: Shot peening can not only form a residual compressive stress layer on the surface, but also improve the stress distribution state inside the gear to a certain extent, reducing the risk of failure caused by stress concentration.

[0003] When shot peening the gears of the reducer, the gears need to be placed in the centrifuge through a hanging fixture. The traditional hanging fixture for gear shot peening has shortcomings when used. It cannot achieve batch hanging of reducer gears while adjusting the hanging angle and position according to needs during the hanging process. Therefore, it is necessary to optimize and improve the traditional hanging fixture for gear shot peening. Utility Model Content
