Analyze the accidents that are easily caused during the running-in period of the reducer

1. Poor lubrication

Since the fitting clearance of the newly assembled parts is small, and due to assembly and other reasons, the lubricating oil is not easy to form a uniform oil film on the friction surface to prevent wear.As a result, the lubrication efficiency is reduced and the early abnormal wear of the parts is caused.In severe cases, the friction surface of the precision fit will be scratched or occluded, resulting in failure;

2. Leakage occurs

Due to the loosening of parts, vibration and the influence of the heat of the reducer, leakage will occur on the sealing surface of the reducer and pipe joints; some casting defects are difficult to find during assembly and debugging, but due to the vibration during operation, Impact, this defect is exposed, manifested as oil leakage.Therefore, occasional leakage occurs during the break-in period;

3. Loose

The newly machined and assembled parts have deviations in geometric shape and matching size. In the early stage of use, due to alternating loads such as shock and vibration, as well as the influence of factors such as heat and deformation, as well as excessive wear and other reasons, it is easy to cause damage. The originally tightened parts are loose;

4. Fast wear and tear

Due to the influence of factors such as the processing, assembly and debugging of the new reducer parts, the contact area of ​​the mating surface is small, and the allowable torque is large.During the operation of the reducer, the concave and convex parts on the surface of the parts fit and rub against each other, and the metal chips that fall off, as abrasives, continue to participate in the friction, which accelerates the wear of the matching surfaces of the parts.Therefore, the content of the running-in period is likely to cause the wear of the parts, and the wear speed is too fast.At this time, if it is overloaded, it may cause damage to components and cause early failure;

5. Many operating errors

Due to insufficient understanding of the structure and performance of the reducer, it is easy to cause failures due to operational errors, and even cause mechanical accidents and safety accidents.
