After leaving the factory, planetary reducers typically come with a running-in period of around 200 hours. This running-in period is an important step in ensuring the proper operation of the reducer, reducing the incidence of failures, and extending its service life. Shanghai ZuoLi Motors reminds that the following aspects should be taken into consideration during the running-in period of planetary reducers. 1. Planetary gear reducers wear out quickly: Due to factors such as the machining, assembly, and calibration of new reducer components, the contact area between the mating surfaces is small, whereas the allowable torque is high. During operation, the planetary reducer sees the uneven surfaces of its components rubbing against each other; the metal debris resulting from this friction acts as an abrasive, further contributing to the friction and thus accelerating the wear of the surfaces in contact. Therefore, the running-in period can easily cause wear on the components (especially the mating surfaces), with a rapid wear rate. At this point, if it operates under overload conditions, it may cause damage to the components and lead to premature failure. https://www.zuolidj.com/uploads/ueditor/20200711/1-200G111140X43.jpg 2. There are many operational errors with planetary gear reducers: Due to a lack of understanding of their structure and performance (especially among new operators), such errors can lead to malfunctions, and even mechanical accidents and safety incidents. 3. Poor lubrication of the planetary reducer: Due to the small clearance between the newly assembled components, and as a result of factors such as assembly, it is difficult for the lubricating oil (grease) to form a uniform oil film on the friction surfaces in order to prevent wear. This reduces the lubrication efficiency, leading to premature abnormal wear of the components. In severe cases, it can cause scratches or interlocking on the friction surfaces that require precise fit, leading to failures. 4. Loosening of planetary reducers: Newly machined and assembled components may have deviations in their geometric shapes and fitting dimensions. In the early stages of use, due to alternating loads such as shocks and vibrations, as well as factors like heat and deformation, coupled with rapid wear, the originally tightened components can easily become loose. 5. Leakage in planetary reducers: Due to loose parts, vibration, and heat exposure, leakage can occur at the sealing surfaces of planetary reducers as well as at pipe joints. Some defects resulting from casting issues are difficult to detect during assembly and testing, but they become apparent due to vibration and impact during operation, manifesting as oil leakage. Therefore, leaks may occur occasionally during the running-in period. https://www.zuolidj.com/*nwendongtai/603.html
