[0002] The motor reduction gearbox is a common mechanical transmission device used to transmit the power of the high-speed rotation of the motor through gears and reduce it to the required output speed. This device is widely used in industries, household appliances, automobiles and other fields. Gears are mechanical parts that transmit power and motion through the meshing between teeth. The basic principles of gears include gear ratios, gear tooth design, gear module, etc. The transmission ratio refers to the angular velocity ratio between the input shaft and the output shaft of the gearbox. The selection of the transmission ratio determines the output speed and torque. In general, the transmission ratio is adjusted by changing the number of teeth on the input and output gears to meet specific work requirements. Gears are usually made of metal materials, such as steel, aluminum alloy, etc., to ensure sufficient strength and wear resistance. The manufacturing process includes forging, casting, machining, etc., which affect the accuracy and durability of the gears. In high-speed motion, the gears will generate friction and heat. Therefore, the lubrication and cooling system is a key part in the design of the gear reducer, which is used to reduce friction, reduce wear, and keep the gears running within the appropriate temperature range.
