PMRV（Rot-Vector） transmission is a new type of transmission developed on the basis of cycloidal pinwheel transmission. The PMRV reducer is composed of an involute cylindrical gear planetary reduction mechanism and a cycloidal pinion planetary reduction mechanism. The involute planetary gear is integrated with the crankshaft as an input to the cycloidal pinion drive section. The crankshaft drives the cycloidal wheel for eccentric motion. The crank rotates clockwise one clockwise direction and the cycloidal wheel moves one tooth counterclockwise. The core components of the PMRV reducer are the pin shell, the crank shaft and the cycloidal wheel. PreciMotion is the high-tech enterprise integrated of R & D, manufacturing and sales for engineering planetary gearbox RV Reducer with focus on the high precision transmission. PreciMotion Reducer products are manufactured with latest German technology and are featured with high precision, high rigidity, high torque, high loading and low noise. Domestically produced precision reduction gear that has excellent accuracy, rigidity, torque, and load sup capabilities. The RV Gearbox series is highly regarded for its reliability. Cycloidal drives can start with zero backlash and high torque capacity while compact in size, unlike Involute gearboxes. They are useful in situations where low speed with high torque capacity is needed. Cycloidal gearbox may be designed with significantly higher contact areas for their size than any gear-based transmission such as epicyclic gears, applying force through many of the 'teeth' at once, allowing very high torque output for the size of the drive at the cost of utilising sliding contact. img Highlights of Precision Reduction Gear PMRV High accuracy(backlash & lost motion: Less than 1 arc.min.) High rigidity High shock load resistance High torque density(High torque & Compact body) High range of reduction ratios Minimal vibration
