The RV reducer is composed of a cycloidal pin wheel and a planetary support. It is widely used in industrial robots, machine tools, and medical applications due to its small size, strong impact resistance, large torque, high positioning accuracy, low vibration, and large reduction ratio. Detection equipment, satellite receiving system and other fields.
The RV reducer has good rigidity, strong impact resistance, smooth transmission, and high precision. It is suitable for medium and heavy load applications. However, the RV reducer needs to transmit a large torque, bear a large overload impact, and ensure the expected working life. In the design, a relatively complicated over-positioning structure is used, and the manufacturing process and cost control are difficult. The RV reducer has no elastically deformed force components inside, so it can withstand a certain torque. The bearing of the RV reducer is its weak link. It is easy to break through the bearing force limit and cause abnormal wear or breakage of the bearing. This problem is more prominent during high-speed operation, so the rated torque of the RV reducer decreases significantly with the input speed.
