Planetary reducers offer advantages such as a compact structure, small return gap, high precision, long service life, and a high rated output torque. However, they are slightly more expensive. Gear reducers feature small size and high torque transmission. Designed and manufactured on the basis of a modular assembly system, they offer a wide range of motor combinations, mounting options, and structural schemes. The transmission ratios are finely graded to meet various operating conditions, achieving mechanical and electrical integration. Gear reducers have high transmission efficiency, low energy consumption, and superior performance.
