[0002] A gear reducer uses gear transmissions at all levels to achieve the purpose of speed reduction. The reducer is composed of gear pairs at all levels. For example, using a small gear to drive a large gear can achieve a certain speed reduction purpose. And the gear reducer needs to be regularly lubricated with lubricating oil to lubricate the internal gears, which can reduce the wear of the gears and increase the service life of the gears;
