[0001] This utility model belongs to the technical field of motor reduction gearboxes, specifically relating to an automatic assembly device for gaskets in a reduction gearbox. Background Technology

[0002] A reduction gearbox for an electric motor, often simply called a "gearbox" or "reducer," is a precision transmission device connecting the output shaft of the motor (or motor itself) and the working mechanism. It is used to reduce the high-speed rotation of the motor and increase the torque through gear transmission. A miniature geared motor refers to a complete drive device that integrates a miniature motor and a reduction gearbox. It is a power source with low-speed, high-torque output characteristics.
