Simple diagnosis and precise diagnosis of rolling bearings

Keywords: simple diagnosis and precise diagnosis of rolling bearing 1 introduction bearing ( 轴承) As the main components of locomotive ( 装配单元) , especially the traction motor and axle box bearing, its function plays an important role in transportation safety ( 角色) , locomotive running online, once the fault of the bearings, will cause the clogging in the whole trains cannot run, ( dǔsè ) Transportation trunk line, especially the passenger train fails, the negative impact is bigger, once the locomotive bearing failure occurs at the same time, the locomotive repair is very difficult, so as to prevent or reduce the locomotive bearing fault occurs, transportation is very important to the security of locomotive, can in front of the bearing loading would have detected the problems of bearing, ensure that qualified bearing parts get in the car is the focus of this paper. 2 bearing ( 轴承) The failure bearing ( 轴承) Seriously damage is often not a single reason, but under the effect of several aspects comprehensive, in harsh operating conditions ( 蒂雅 阿贾 n) Under a vicious cycle, leading to a serious loss bearing, so after the accident, it is often difficult to determine is caused by what, also bring some difficulties to our relevant measures, convenient for discussion, first from several aspects to analyze the causes of bearing failure. 2. 1 bearing abnormal abrasion of 2. 1. When bearing use after a period of time, bearing inner ring, rolling element and cage, outer ring raceway produce certain defects, such as scars, caused the bearing lubrication ( lubrication) Bad, cause the bearing of fever, fever for a long period of time, can lead to: ( 1) Bearing lubrication ( lubrication) Oil ( 润滑油) The dilution. Jiaxing bearing co. , LTD. , when the centerline of shaft and bearing seat centerline not overlap and the Angle error, or because of the axial force and bending or tilt, will cause the bearing inner and outer circle of the axis deflection. At this time, should adopt a self-aligning properties of self-aligning bearings or insert ball bearings. ( 2) Accelerate the fatigue of material, hardness, 硬度) Decline. Due to these reasons, and further form vicious circle, accelerated overheating and make the bearing damage. Serious displacement of bearing inner ring, rolling body round, heating, welding together in the end. So in the online operation, such as found bearing severe fever, smoke, don't stop, and should keep running to stand ahead, because this moment overheated bearings in melting state, once the parking is unable to walk again after cooling, jam, dǔsè ) Trunk line.
