Improper Design Fit Between Bearing And Shaft

បានប្រកាសនៅ Business នៅOctober 13 2021 at 08:57 AM

The clearance of rolling bearing of ore milling plant is divided into radial clearance and axial clearance. Radial clearance is divided into original clearance, installation clearance and working clearance.

The selection of clearance shall consider the fit between bearing and shaft and bearing seat, the change of original clearance caused by working temperature and load.

The reasonable selection of bearing clearance should consider the variation of clearance caused by fit, temperature difference between inner and outer rings and load on the basis of original clearance, so as to make the working clearance close to the best state.

The rolling bearing of ore milling plant is not properly matched with the shaft or hole. When the bearing works, due to the influence of friction heating and other heat sources, the temperature of the ferrule will be higher than that of the matched parts.
