Precision reduction Gear RV-C series reducer

YH RV-C is a two-stage gear reducer which consists of the 1^st stage of planetary gear reducer and the 2^nd stage of cycloidal pin-wheel reducer. The first speed reduction is achieved by the meshing between the big gear of center gear and the planetary gear based on the gear reduction ratio. The planet gear is connected to the crank shaft and the rotation of crank shaft causes the eccentric rotation of the cycloid disc. This achieves the second speed reduction and thus if the crack shaft rotates 360 degrees. The cycloid disc will rotate one tooth in the opposite direction

FQA

Q: What should I provide when I choose a gearbox/speed reducer?
A: The best way is to provide the motor drawing with parameters. Our engineer will check and recommend the most suitable gearbox model for your reference.
Or you can also provide the below specification as well:
1) Type, model, and torque.
2) Ratio or output speed
3) Working condition and connection method
4) Quality and installed machine name
5) Input mode and input speed
6) Motor brand model or flange and motor shaft size
