Simply put, a speed reducer is an intermediate mechanism that connects the power source and the actuator, with the function of matching the speed and transferring the torque. According to the division of control precision, reducer can be divided into general transmission reducer and precision reducer. General drive reducer has low control accuracy and can meet the basic power transmission requirements of mechanical equipment. Precision reducer return clearance is small, high precision, long service life, more reliable and stable, used in robotics, CNC machine tools, medical equipment and other high-end fields.
There are more types of precision reducers, including harmonic reducer, RV reducer, cycloid planetary reducer, precision planetary reducer and so on. In recent years, with the rapid development of industrial robots, high-end CNC machine tools and other intelligent manufacturing and high-end equipment field, harmonic reducer and RV reducer has become a precision reducer widely used in the field of high-precision transmission.
