Compared with winter, problems such as fire and breakage are more likely to occur during high-speed operations. Conclusion In short, as long as you pay attention to the operation site and retain the leftover objects of the failed insert bearing, carefully observe and analyze, and continuously summarize and accumulate experience, you can find the method and idea to solve the problem and benefit from the analysis of the operating environment and damage traces of the failed insert bearing. Since this is only a pressure effect, the molten material does not move or transform, causing the underlying layers to disengage, eventually causing material damage or wear. In the case of a small amount of interference, the end face of the insert bearing ferrule can be pressed with a sleeve at room temperature, and the sleeve can be tapped with a hammer to press the ferrule evenly through the sleeve. In addition, different grinding wheel hardness, structure, abrasive grain size, abrasive types, as well as different coolant compositions, will have a certain impact on the roundness of grinding. Oil is roughly divided into: (oil bath dripping oil splash (circulation (spray (oil mist) Precautions when installing the insert bearing to ensure the cleanliness of the insert bearing and the installation environment The insert bearing industry has emphasized to users: watch There is not even a speck of dust in it, not to mention the insert bearing is a much more precise mechanical component.
Dust will destroy the integrity of the oil film and cause contact potential difference corrosion, which is a common factor causing wear, fatigue, and rust, and the impact is extremely bad. However, before the above stage, the wear of the insert bearing is relatively slight, and the fatigue may only occur in the depth of several microns to tens of microns under the surface layer of the rolling surface. Therefore, the insert bearing can be repaired at this time and can be obtained at a small cost. Better repair effect. It is advisable to use this method together with the voice recognition method. Due to the different working pressure ranges and starting pressures of various vacuum pumps, these requirements must be met when selecting vacuum pumps. High-frequency quenching insert bearing steel was developed, and ordinary medium-carbon steel or medium-carbon manganese and chrome steel was used to replace ordinary insert bearing steel by high-frequency thermal quenching, which not only simplified the production process, but also reduced the cost, and improved the service life. The structure of the sliding insert bearing is generally composed of a bearing bush and an insert bearing seat. If installed in large quantities, hydraulic presses can be used.
Therefore, for manufacturers, to avoid this situation, on the one hand, they should pay attention to selecting high-temperature resistant needle roller insert bearings, and on the other hand, they should also pay attention to adjust the running speed of the machine and controlling heat dissipation in time. In the manufacture of a rolling insert bearing, the process documents are generally divided into three categories: the dominant process documents, the management process documents, and the productive process documents. The actual contact stress remains stable at positions lower than the equivalent stress due to the increase in the contact area caused by the groove. When pressing in, it should be ensured that the end face of the outer ring and the end face of the shoulder of the shell, and the end face of the inner ring and the end face of the shaft shoulder are pressed tightly, and no gap is allowed. It is identified by the state of the agent. The agent is sampled and analyzed, and it is judged by the degree of turbidity, whether foreign matter or metal powder is mixed. In short, the repair period of the rolling insert bearing is when the insert bearing has been working for a long period and has been fully utilized, and it is appropriate to enter the repair before the damage occurs.
