Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gear machining and particularly relates to a grinding device for planetary reducer gear machining. BACKGROUND

[0002] The planetary reducer is widely applied to engineering machinery, automatic production lines, precision instruments and many other key devices due to high transmission efficiency, strong load capacity and accurate transmission ratio. As a core transmission component of the planetary reducer, the gear directly affects the overall performance and service life of the reducer. Therefore, in the machining process of the planetary reducer gear, the grinding as the final precision machining process is crucial to the performance of the device and the advancement of the machining process.

[0003] According to the search, in the published patent (CN216028534U A high-precision gear grinding device), when the device is used to machine gears of different sizes, the movable rod can be moved upward along the second sliding bar. The movable rod moves upward while driving the fixed block to move upward and extruding the spring. With the movement of the fixed block, the fixed block gradually separates from the fixed groove on the telescopic plate, so that the telescopic plate and the fixed disc are in a loose state. At this time, the telescopic plate can be pulled outwards by the circular arc plate. When the circular arc plate moves to the appropriate position, the movable rod is loosened. Under the action of the spring, the movable rod drives the fixed block to return to the original position. The fixed block reenters a new fixed groove and re-fixes the telescopic plate and the fixed disc. Another telescopic plate and circular arc plate are moved in the same way. In this way, the length of the telescopic plate can be changed indirectly to change the diameter of the fixed disc. Thus, the device can fix gears of different sizes, improving the practicality of the device. Although the device can fix gears of different sizes, the device needs to be manually adjusted by the staff during fixing, which makes the gear feeding and taking efficiency low, thereby affecting the gear machining efficiency. Moreover, the device does not have a cooling structure. During the gear grinding process, the grinding wheel and the gear surface will generate intense friction, thereby generating a large amount of heat. If the device does not have a cooling structure, the local temperature of the gear will be too high. High temperature will change the performance of the gear material, thereby affecting the wear resistance and service life of the gear. Therefore, we propose a new grinding device for planetary reducer gear machining. SUMMARY
