[0002] Gears are mechanical parts with teeth that can mesh with each other. They are widely used in mechanical transmission and the entire mechanical field. The basic function of gears is to transmit power and motion, and to change the speed and direction. When processing gears, it is necessary to grind the embryonic disc initially. However, the existing gear grinding device can only grind one gear separately, and after grinding the gear, the polished gear needs to be removed, and then the unpolished gear needs to be installed. The grinding component cannot work when disassembling and installing the gear, which prolongs the gear processing time and reduces the gear processing rate. In addition, only one side of the gear can be polished, which is inefficient.
