After a gear motor leaves the factory, it is generally stipulated that there is a running-in period of about 200 hours (over time, the oil must be changed), which is stipulated by the technical characteristics of the initial use of gear reduction machinery. The run-in period is an important link to ensure the normal operation of the gear reducer, reduce the failure rate and extend its service life.

Small planetary geared electric motor factory technicians gave the following points for attention:

1, wear speed is fast

Due to the influence of machining, assembling and debugging of the parts of the new gear reducer, the contact area of the mating surface is small, and the allowable torque is large. During the operation of the gear reducer, the convex and convex parts of the surface of the parts interact with each other, and the metal debris worn down as an abrasive continues to participate in friction, which accelerates the wear of the surface of the parts. Therefore, it is easy to cause wear of parts (especially the matching surface) during the running-in period, and the wear speed is too fast. At this time, if the overload operation, it may lead to the damage of parts, resulting in early failure.

2, the operation mistakes

Due to the insufficient understanding of the structure and performance of the gear motor (especially the new operator), it is easy to cause failure due to operational errors, and even cause mechanical accidents and safety accidents.

3, poor lubrication

Due to the small clearance of the newly assembled parts, and due to assembly and other reasons, the lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. Thus, the lubrication efficiency is reduced, resulting in early abnormal wear of the machine parts. In serious cases, it will cause scratches or bite on the friction surface of the precise fit, resulting in the occurrence of failures.

4, loose

Newly processed and assembled parts, there is a deviation of geometric shape and matching size, in the early days of use, due to impact, vibration and other alternating loads, as well as heat, deformation and other factors, coupled with rapid wear and other reasons, it is easy to loosen the original fastening parts.

5. Leakage occurs

Due to the loosening of the parts, vibration and the influence of the gear reducer by heat, the sealing surface and pipe joint of Small planetary geared electric motor will appear leakage phenomenon; Some defects, such as casting, are difficult to find during assembly and debugging, but due to the vibration and impact of the operation process, this defect is exposed, manifested as leakage (seepage) of oil. Therefore, the running-in period will occasionally appear leakage phenomenon.
