what's the difference between it and traditional reducer?

The RV reducer, short for Rotate Vector Reducer, is a novel type of two-stage enclosed cycloid planetary drive that has evolved from traditional cycloidal drives. It is characterized by its unique and compact structure, which enables high gear ratios and torque output within a small volume. Compared to traditional reducers, the RV reducer offers several distinct advantages:

  1. Compact Design: The RV reducer is composed of a cycloidal gear and a planetary, allowing for a high transmission ratio and torque density in a compact form factor.

  2. Precision and Stability: With high precision (backlash less than one arc minute) and rigidity, the RV reducer maintains long-term accuracy and stability. Unlike some traditional reducers, its performance does not significantly degrade over time.

  3. Efficiency and Performance: The RV reducer boasts a transmission efficiency that can reach 85% to 95%, significantly higher than many traditional reducers. This means it can transmit the same torque and power in a smaller volume, or handle more load for the same size.

  4. Application Range: Due to its high-performance characteristics, the RV reducer is widely used in fields such as industrial robots, machine tools, medical testing equipment, and satellite reception systems. It is particularly favored in the joints of industrial robots where precision and stable performance are required.

  5. Design and Manufacturing: The design and manufacturing of RV reducers demand high precision and quality, especially in the processing of needle gears, needle shells, and needle pins. The materials and craftsmanship required make the production of precision RV reducers challenging.

In summary, the RV reducer stands out from traditional reducers with its compact design, high precision, and efficient performance, making it a popular choice in modern precision transmission applications.
