Apart from the cause for the low concentricity of the output assembly of the reducer, there will be the following conceivable explanations should the drive motor's shaft be nonbroken yet the reducer's output shaft breaks.
First of all, the incorrect decision results in inadequate reducing production. Some consumers choose the type wrongly thinking that as long as the chosen reducer's rated output torque satisfies the operating criteria, but this is not the case.
In theory, the rated output torque of the drive motor lessens by the speed ratio than the matching rated output torque supplied by the reducer product sample.
In practical uses, one should take into account the maximum operating torque of the drive motor and overload capacity.
Theoretically, the maximum working torque demanded by the user has to be less than two times the reducer's output torque.
This criterion especially has to be rigorously followed in various applications not only to safeguard the internal gear and shaft system of the reducer, but also mostly to prevent the output shaft of the reduction from being twisted and damaged. Once a problem with the equipment installation arises, the output shaft of the reducer becomes stuck by the load and the overload capacity of the drive motor will still increase the output until the force on the output bearing of the reducer exceeds its maximum output torque, so twisting the shaft. If these elements are not considered, Grooves of the torsional output shaft will be avoided in case the rated output torque of the reducer allows margin.
