The preliminary cause of death led to a diagnosis of bearing the stator sweep chamber explosion last shooting. Xi'an maintenance reasons cause the motor stator DC sweep chamber may have: The motor bearing housing is a motor than the important role of the motor bearing sleeve is used to protect the drive shaft, for some difficult to repair, disassemble or higher value of the drive shaft, To protect the shaft from wear and tear, will be installed in the design process outside the shaft sleeve, and then install the bearing on the hub, easy installation and maintenance. Effective solution with the bearing housing, protecting the bearing mounting hole, processing and interchangeability. Too loose or too tight will lead to some serious consequences. Bearing sleeve is too loose, the bearing easily. This will result in rolling bearing wear, bearing outer ring and the end cap is not tight fit, there outer rims and bearing relative motion, which ran coat. Because of these failures, bearing position is not fixed, causing the stator and rotor friction. Local overheating of the motor, the motor can not operate normally serious. Bearing sleeve loose troubleshooting methods are: all bearing damage, broken balls or ball holder is damaged and must be replaced with new bearings; when running light sets, should be placed on a lathe knurled shaft, so that an interference fit with the reality, in combination face of the bolt with a saddle. Or in parts of the shaft and the bearing contact spray a layer of nickel, it will give the prolonged use of bearings. Bearing sleeve is installed within tight, then make the bearing sleeve by a radial direction force increases, the requirements of the rolling element bearing clearance value becomes small. Friction between the bearing and the shaft becomes larger, is not running smoothly, running fever, bearing temperature higher, resulting in a serious bearing explosive death.
