The high-precision cycloidal CT-CRV-P reduction gear is primarily utilized in the joints of industrial robots and represents a cycloidal pin wheel planetary reduction gear developed based on the principle of planetary engagement transmission. During transmission, this type of reduction gear is characterized by having a large number of teeth engaged, minimal backlash, and reduced vibration and inertia. It is compact, lightweight, highly rigid, and capable of withstanding overloads, ensuring smooth operation of the robot and achieving high levels of transmission and positioning accuracy.
