Description

Technical Field

[0001] The invention relates to the technical field of planetary reducer gear shaft processing, in particular to a gear shaft grinding processing device for planetary reducer production. Background Art

[0002] The planetary reducer is mainly composed of a sun gear, planetary gears, an inner gear ring and a planet carrier. The sun gear is located at the center. The planetary gears rotate while revolving around the sun gear. The planetary gears mesh with the inner gear ring. The power is transmitted from the input shaft to the sun gear, and the sun gear drives the planetary gears to rotate. The planetary gears then output the power through the planet carrier. This transmission method is similar to the movement of planets in the solar system, hence the name planetary reducer. In the planetary reducer, a large reduction can be achieved by reasonably designing the number of teeth of the sun gear, planetary gears and inner gear ring. In order to improve the transmission efficiency of the planetary reducer, a variety of technologies are used in the design and manufacture of gears. The first is the optimization of the gear tooth profile. The use of precise tooth profile designs such as involute tooth profiles can ensure good contact of the gears during the meshing process and reduce energy loss. In addition, in terms of gear processing accuracy, high-precision gear grinding processes are used to reduce the roughness of the gear tooth surface and improve the smoothness of the meshing. The planetary reducer gear shaft is a key component in the planetary reducer. The quality of its processing technology directly affects the performance, accuracy and service life of the planetary reducer. In the existing technical field, a single device for grinding the gear shaft of a planetary reducer can only be used for large-area grinding or fine grinding. The overall processing needs to be transferred between different devices, which consumes a lot of loading and unloading, transportation and re-clamping time. In addition, different grinding equipment has differences in processing characteristics such as grinding force and grinding speed. During the equipment conversion process, the surface of the gear shaft will be affected by different processing characteristics, which is prone to problems such as uneven surface microstructure and unreasonable residual stress distribution, thereby affecting the surface quality and service life of the gear shaft.
