1. Withstand abnormal radial force and shaft bending
When the assembly of the motor and the reducer is not concentric, the output shaft of the reducer will bear abnormal radial force from the input end. This radial force will act on the output shaft for a long time, forcing it to bend and deform. Moreover, as the output shaft rotates, the direction of bending and lateral force will continue to change (a 360-degree change per rotation).
2. Metal structure damage and temperature rise
The continuous radial force generated by concentricity error will increase the temperature of the output shaft, causing its metal structure to be continuously destroyed. As the error increases, this damaging process accelerates.
3. The output shaft is broken
When the radial force accumulates for a long time and exceeds the maximum radial load that the reducer output shaft can bear, it will eventually cause the output shaft to break. Since the output of the reducer is the product of the output of the drive motor and the reduction ratio, the output is greater than that of the motor, so the output shaft of the reducer is more likely to be broken when the assembly is not concentric.
4. Gear wear and precision loss
Installation deviations (such as misalignment of the shaft system and insufficient coaxiality) will cause uneven force during the transmission process. After long-term operation, it will aggravate the wear of the internal gears and induce a decrease in accuracy and torque attenuation.
5. Inducing collateral damage to the input terminal
When the output shaft is damaged due to installation deviation, the input end of the reducer will also bear radial force from the motor. If the radial force exceeds the maximum radial load, it will also cause the input end of the reducer to deform or even break.
To sum up, when installing the R series gear reducer, the assembly concentricity between the motor and the reducer must be strictly controlled to ensure that the outer flanges of the two are parallel and closely matched. This is a key prerequisite to ensure the smooth operation of the equipment and prevent the output shaft from breaking and the internal gear wear.
