The high-precision cycloidal CT-CRV reducer for robots is primarily applied to the joints of industrial robots and is a type of cycloidal pinwheel planetary reducer developed based on the principle of planetary engagement transmission. When the reducer is in operation, it features a large number of engaging teeth, minimal backlash, low vibration, and low inertia. It is characterized by compactness, lightweight, high rigidity, and overload endurance, ensuring smooth operation of the robot and achieving high transmission and positioning accuracy.
