5 problems that are easy to appear during the running-in period of Shanghai reducer. Have you noticed?

Recently, some customers reported that the Shanghai reducer failed after it was used less, so they questioned the quality of our products. A subsequent investigation by our company's technical staff found that because some customers did not know the Shanghai reducer in place and ignored the running-in period of the Shanghai reducer. During the running-in period, they did not pay attention to some of the prone problems of the Shanghai reducer. After using the Shanghai reducer for a short time, one or more failures occurred.
In fact, after a Shanghai geared motor leaves the factory, there is generally a running-in period of about 200 hours (the oil must be changed after this time), which is stipulated by the technical characteristics of the Shanghai geared motor in its initial stage. The running-in period is an important part to ensure the normal operation of the Shanghai reducer, reduce the failure rate and extend its service life. The technicians of Shanghai reducer factory gave out the problems that should be noticed during the running-in period:
1. Fast wear speed
Due to factors such as processing, assembly and commissioning of the new Shanghai reducer parts, the contact area of the mating surface is small and the allowable torque is large. During the operation of the Shanghai reducer, the concave and convex parts on the surface of the parts are fitted and rubbed against each other. The metal scraps that have fallen off also serve as abrasives and continue to participate in friction, which accelerates the wear of the mating surfaces of the parts. Therefore, during the running-in period, parts and components (especially mating surfaces) are easily worn, and the wear speed is too fast. At this time, if it is overloaded, it may cause damage to components and cause early failure.
2. Poor lubrication
Because the fitting clearance of the newly assembled components is small, and due to assembly and other reasons, it is not easy for the lubricant (grease) to form a uniform oil film on the friction surface to prevent wear. As a result, the lubricating efficiency is reduced, causing early abnormal wear of the parts. In severe cases, it can cause scratches or occlusions of the friction surface of the precision fitting, resulting in failure.
3. Looseness occurs
Newly assembled components have deviations in geometry and fit dimensions. At the beginning of use, they are easily affected by alternating loads such as shocks and vibrations, as well as heat and deformation, and excessive wear. The originally tightened parts become loose.
4. Leakage occurs
Due to the looseness and vibration of the parts and the heat of the Shanghai reducer, there will be leakage in the sealing surface and pipe joints of Shanghai reducer; some casting defects are difficult to find during assembly and debugging, but due to the Vibration and shock, such defects are exposed, showing up as oil leakage (seepage). Therefore, leakage occurs occasionally during the break-in period.
5.Many operating errors
Due to insufficient understanding of the structure and performance of Shanghai reducers (especially for new operators), it is easy to cause malfunctions due to operating errors, and even cause mechanical and safety accidents.
After the above introduction, I hope that it can be helpful to the staff who lacks the basic operation knowledge of Shanghai reducer. For more information about Shanghai reducer operation, please pay attention to the official website of Shanghai Yulong Reducer Co., Ltd. rubyrad.com .
