The reducer is a mechanical device that is generally used for two purposes. Its main purpose is to multiply the torque generated by the input power to increase the available work. They also reduce the speed of the input power to achieve the desired output speed. Here we bring you the reducer repair and failure analysis, let’s get to know it together.
Reducer maintenance and failure analysis
Despite careful design and strict selection analysis, the reducer is still prone to wear and failure. In order to extend its service life as much as possible, proper maintenance procedures should be established. The more important factor is the daily oil change. Under load, oil and grease molecules decompose under the extreme pressure of meshing gear teeth. The shearing action of gear cutting oil and the high temperature in the box can also cause oil damage. When oil and grease lose their lubricating properties, the decelerator wears out quickly.
Although a certain number of failures can be attributed to material or process problems, when the reducer fails prematurely, it is usually due to operating conditions or application dynamics. When an overload causes a failure, it is usually because the original design standards have changed, the appropriate service factor has not been applied, the oil has not been changed, or there is a significant shock load. When a bearing fails, it is usually caused by excessive overhanging load, shaft misalignment or overheating. When the seal fails, it is most likely because there is something between the seal and the shaft, or because they are painted, dried, and become brittle.
