1. Wear fast
Due to the influence of the processing, assembly and debugging of the new gear reducer parts, the contact area of the mating surface is smaller, and the allowable torque is larger. In the process of operation, the concave and convex parts of the surface of the parts are inlaid with each other, and the metal debris, as abrasives, continue to participate in the friction, which accelerates the wear of the matching surface of the parts.
2. Many mistakes in operation
Due to the lack of understanding of the structure and performance of the reduction motor (especially the new operator), it is easy to cause failure due to operational errors, and even mechanical accidents.
3. Poor lubrication
Due to the small fit clearance of newly assembled gear reducer parts, and due to assembly and other reasons, lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. So as to reduce the lubrication efficiency and cause the early abnormal wear of parts. If it is serious, it will cause scratch or bite on the friction surface of precision fit, leading to failure.
4. Loosening occurs
In the initial stage of use, due to the impact, vibration and other alternating loads, as well as the influence of heating, deformation and other factors, coupled with the rapid wear and other reasons, it is easy to make the original fastening parts loose.
