RV reducer is a worm gear reducer in a more common, it is composed of worm gear, worm gear, compact structure is relatively large, in some cases can also automatically lock, is currently the most widely used reducer, its small vibration, low noise, low energy consumption RV reducer usually in low speed large torque driving device, the motor internal combustion engine or other high speed running power, The less gear on the input shaft of the reducer meshes with the larger gear of the output shaft, so as to realize the reducer. Reducer is a transmission device, it through the transformation of transmission device, the motor rotation speed down to the expected amount of rotation, so as to obtain more torque.

At present, the application range of industrial robots is more and more wide, among which the most relevant is RV reducer, RV drive is a precision transmission mechanism based on cycloidal needle wheel, RV reducer includes two parts, gradually open cylindrical gear planetary reducer and cycloidal needle wheel planetary reducer, the new gear on the involute is connected to the crankshaft, and will be used as an input end, Crankshaft drive cycloidal wheel by eccentric rotation, RV reducer is mainly composed of needle tooth shell, crankshaft, cycloidal needle wheel, through the gear rotation speed, the motor rotational speed slow to the required amount of rotation, in order to obtain greater torque, the speed down, torque increase, in the core parts of the robot, the reducer is the most important. (Strong impact resistance, smooth transmission, high precision, suitable for medium and heavy load situations)
