1. Precision:
RV reducers offer higher stiffness and rotational precision, making them suitable for heavy-load applications such as the base, arm, and shoulder of robots.
Harmonic reducers are known for their extremely high precision, with errors typically within 1 arcminute, significantly improving the positioning and control accuracy of robots.
2. Torque and Stiffness:
RV reducers provide higher torque and stiffness, enabling them to handle heavier loads and ensure stability during operation.
Harmonic reducers, with their flexible gear transmission, can output large torques, increasing the acceleration and speed of robots, enhancing their dynamic response capabilities.
3. Volume and Weight:
While RV reducers may be heavier compared to harmonic reducers, they offer a short transmission chain, compact size, high power-to-weight ratio, and ease of control, making them suitable for articulated robots.
Harmonic reducers achieve high torque output in a smaller space and lighter weight, ideal for serial-type robotic arms and humanoid robots.
4. Other Characteristics:
Harmonic reducers are also known for their low noise, small backlash, and energy efficiency, further enhancing the motion control and stability of robots.
