Nowadays, more and more people use precision planetary reducer, not only because of its good performance, low energy consumption, but also cheap, the specific price of the editor will not disclose, however, the advantages of more does not mean that it will not fail, a lot of people due to the neglect of such a problem led to a reducer once damaged, the main faults?
1. Many operational errors: Due to insufficient understanding of the structure and performance of the geared motor (especially new operators), it is easy to cause failures due to operational errors, and even cause mechanical accidents and safety accidents.
2. Wear fast: due to the new precision planetary reducer parts processing, assembly and commissioning and other factors, the contact area of the mating surface is small, and the permissible torque is large. Precision planetary reducer in the operation process, the parts surface of the concave and convex part of the friction embedded in each other, grinding down the metal debris, and as an abrasive, continue to participate in the friction, more accelerated parts with the surface of the wear. Therefore, the break-in period is easy to cause parts (especially with the surface) of the wear and tear, the wear rate is too fast. At this time, if overloaded operation, it may lead to damage to the parts, resulting in early failure.
3. Loosening: new processing and assembly parts, there are geometric shape and with the size of the deviation, in the initial period of use, due to shock, vibration and other alternating loads, as well as heat, deformation and other factors, coupled with the wear and tear too fast, etc., it is easy to make the original fastening of parts and components to produce loosening.
4. Poor lubrication: Due to the newly assembled parts of the fit gap is small, and due to reasons such as assembly, lubricant (grease) is not easy to form a uniform film on the friction surface to prevent wear. Thus reducing the effectiveness of lubrication, resulting in early abnormal wear of the parts. In serious cases, it may cause scratches or occlusion on the friction surface of the precision fit, resulting in failure.
5. Leakage phenomenon: due to the loosening of parts, vibration and precision planetary reducer affected by heat, the sealing surface of the precision planetary reducer and pipe joints, etc., leakage phenomenon; part of the casting and other defects, it is difficult to find in the assembly debugging, but due to the vibration of the operating process, impact, such defects are exposed, manifested as oil leakage (seepage). Therefore, the break-in period will occasionally leakage phenomenon.
