How To Deal With The Temperature Of Stainless Steel Bearing Exceeding The Range Of Use

Although stainless steel bearings can be used in high temperature environment, but the temperature under different categories and models is not the same. Therefore, stainless steel bearings will also have its temperature range. Today, Xiaobian will talk to you about how to deal with stainless steel bearings when they work beyond the normal temperature.
1. Stainless steel bearing and journal uneven fit or contact surface is too small (match clearance is too small), the specific pressure per unit area is too large, most of this happens in the new machine test run or new bearing bush; Scraping bearing bush with coloring method, make its contact surface meet the requirements, improve the specific pressure per unit area;
2. Stainless steel bearing deflection or crankshaft bending, distortion; Adjust its fit clearance properly, check crankshaft bending, distortion, according to the situation of new crankshaft or repair;
3. The quality of the bearing bush is not good, the quality of the lubricating oil is not consistent (small viscosity), or the oil circuit is blocked. The supply pressure of the gear oil pump is too low, and the supply is interrupted, resulting in the lack of oil in the bearing bush and dry friction; Check the oil pipeline and gear oil pump with the bearing bush that meets the quality requirements, use the lubricating oil that meets the quality requirements, check and adjust the oil pump to make the pressure meet the requirements;
4. Stainless steel bearings have sundries or too much lubricating oil, or lubricating oil is too dirty. Need to clean and replace the new oil, adjust the oil pressure;
5. Bearing bush has uneven excessive wear, need to replace the bearing bush;
6. When the compressor is installed, the main shaft and the motor (or diesel engine) main shaft coupling are not aligned, and the error is too large, resulting in the tilt of the two shafts. The concentricity of the two machines should be positive and levelled, and the tolerance value should conform to the value specified in the machine specification. For compressor and motor connection with rigid connection, more attention should be paid to find the right.
