Characteristics of cycloidal pinwheel reducer: 1. High speed ratio and high efficiency single-stage transmission, G series reducer can achieve a speed ratio of 1:87, with an efficiency of more than 90%. If multi-stage transmission is adopted, the speed ratio will be even greater. 2. Compact structure and small size. Due to the use of planetary transmission principle, the input shaft and output shaft are on the same axis line, enabling R series reducers to obtain as small a size as possible. 3. Smooth operation and low noise. Cycloidal pinion engagement has a large number of teeth, large overlap coefficient, and mechanism balance principle, which limits vibration and noise to the minimum extent. 4. Reliable use and long life. As the main parts adopt high-carbon chromium steel materials and are treated by quenching (HRC58~62) to obtain high strength, and some transmission contacts adopt rolling friction, they are durable and have a long service life. 5. Reasonable design, convenient maintenance, easy disassembly and installation, fewer parts and simple lubrication make cycloidal pinwheel reducers deeply trusted by users. There are mainly two types of cycloidal reducers: XB cycloidal reducer and WB miniature cycloidal reducer.
