CCR series Structure
The CSR series is a cycloidal reducer that transmits rotation and torque from the input shaft through cycloidal gears, leading to a reduction in speed and an increase in torque at the output shaft. It is a high-precision, high-rigidity reducer designed for motors.
CCR series Features
It has excellent durability as a reducer using a cycloidal tooth profile.
The even engagement of the gear plate and pins ensures good rotational contact and high efficiency.
Structurally robust, it is resistant to impacts, has higher durability compared to other reducers, and operates with low noise, making it easy to use.
By minimizing the tolerances of each component, it achieves high precision with low backlash.
Reduction ratio and rotation direction
|
When the input shaft rotates and the output shaft rotates (body fixed) |
|
|
Reduction gear ratio ( I ) |
-1/R |
|
Sense of rotation |
The rotation direction of the input shaft and the output shaft are opposite |
|
When the input shaft rotates and the body rotates |
|
|
Reduction gear ratio ( I ) |
1/R+1 |
|
Sense of rotation |
Same as the rotation direction of the input shaft |
* For example, a reducer with a gear ratio of 30:1 has a gear ratio of 30 when the output shaft rotates (with the body fixed), and a gear ratio of 31 when the body rotates.
