Cycloid Vertical Reducer Working Mechanism
The Cycloid Vertical Reducer uses a cycloidal motion principle to achieve speed reduction through smooth, balanced torque transmission:
Input Shaft Rotation – The motor drives an eccentric bearing, which initiates controlled cycloidal motion.
Cycloidal Disc Engagement – The hardened cycloidal discs oscillate and mesh with stationary pins in the housing.
Power Output Generation – The oscillating motion is transferred to the output shaft through high-strength needle rollers, generating low-speed, high-torque rotational output.
This innovative design ensures minimal vibration, uniform torque distribution, and ultra-low backlash, making it ideal for high-precision vertical applications.
