Product Specification

Genius Robotics Zhenkang provides a full range of precision cycloid RV gear reducers, which are commonly used in robot positioners, CNC machining centers, and so on.

Principle of RV Gear Reduction of Precision Cycloid Pinwheel

Cylindrical needle rollers are installed in the inner ring of the housing. The eccentric movement of the RV gear causes the needle to mesh and disengage from the cycloidal RV gear teeth, resulting in multiple sets of RV gear teeth meshing with the needle at the same time to improve the load capacity. Since the number of RV gears is one less than that of needle rollers, when the eccentric shaft rotates once, if the case is fixed, the RV gear and the input shaft will rotate by an angle of one tooth in the same direction.

The output end can be a shaft or a case. If the housing is fixed, the drive shaft is output, and the output is in the same direction. If the drive shaft is fixed and the housing is the output, the output direction is exactly the opposite. By replacing the fixed and output parts, different transmission ratios can be obtained.

Difficulties of precision cycloidal pinwheel RV gear reducer

The core difficulty in the manufacture of precision cycloidal pinwheel RV gears lies in the close coordination of various processes, including: tooth surface heat treatment, machining accuracy, part symmetry, group technology, assembly accuracy, etc. The result of the total distribution of these process assembly tolerances is Product wear and life.

The speed reduction of the reducer is realized by the simple principle that the speed is inversely proportional to the number of teeth and the transmission between the large and small gears. But to achieve a large transmission ratio, if we use cylindrical gears that we usually see, the volume of the entire gearbox will be very large. If it is to be as small as possible, what should we do?

What is the function of the RV Gear reducer?

Under normal circumstances, the reducer is installed at the front end of the motor, and the rated speed of common servo motors is 2000 rpm, which is what we often call 2000 rpm. Normally, few devices require such a high speed, especially when the robot is in motion, each joint arm is driven by a belt or screw driven by a reducer.

The reducer is mainly used to reduce the speed and increase the torque. Increasing torque is what we often call torque.

The torque change is based on the product of the reduction ratios of the front and rear gears. For example, if someone tells you that the reduction ratio is 4X5, then it will decelerate by 20 times.

Reducers in other fields are also based on the same principle, which is nothing more than deceleration by gear difference. As for what type of gears are used for the form, the types are different.
