Features：
Compact & slim;
High accuracy;
Overload resistance (withstands 5 times rated torque)；
Good accel. / decel. performance；
Application Scenarios：
Mainly used in industrial robots, CNC machine tools, deflection machine, non-standard automation etc.
The first stage of CRV-E reducer is planetary gear reduction. The rotation of the input shaft is transmitted from the input gear to the planetary gear, and the speed is reduced according to the gear ratio.
The second stage is the deceleration of the cycloid pinwheel. The planetary gear is connected with the eccentric shaft. The rotation of the eccentric shaft drives the cycloid to make an eccentric movement. The eccentric shaft rotates once, and the cycloid will rotate one tooth in the opposite direction to the movement of the eccentric shaft.
Structure
Working Principle
The first stage of CRV-E reducer is planetary gear reduction. The rotation of the input shaft is transmitted from the input gear to the planetary gear, and the speed is reduced according to the gear ratio.
The second stage is the deceleration of the cycloid pinwheel. The planetary gear is connected with the eccentric shaft. The rotation of the eccentric shaft drives the cycloid to make an eccentric movement. The eccentric shaft rotates once, and the cycloid will rotate one tooth in the opposite direction to the movement of the eccentric shaft.
Input shaft speed ratio:
R=1+Z2/Z1*Z3
R: Speed ratio
Z1: Number of teeth on input gear
Z2: Number of teeth on planetary/epicyclic gear
Z3: Number of pins
