Trajectory and loading method of load - bearing knowledge

Bearing a rotation, inner ring and outer ring raceway surface, with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so in the case of remove the bearing, please keep close attention and observation on the surface of the raceway. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check if the bearing with accidents such as whether the load and the installation error of kingdoms, the cause of bearing damage and be investigated for clues. Figure 6 - 1 shows deep groove ball bearings under the condition of different load production. ( 一) Is inner ring rotates can bear radial load quantity of normal orbit. ( c) *( h) Shown in the operation of the trajectory of the bearing has a bad effect, mostly shorter service life. The operation of the roller bearing trajectory ( Figure 6 ~ 2) Also, ( 1) Inside is rotation is to the cylindrical roller bearing used correctly and the outer orbit when the radial load. ( j) Is the inner ring and outer ring relative tilt, the deflection of shaft orbit, orbit, raceway surface on its longitudinal shade, on the load coil outlet has a tilted orbit, double row tapered roller bearing inner ring spinning. ( K) Said only bear radial load of outer trajectory. When L said only by the axial load of the track. Inner ring and outer ring tilted relative big bear radial load, only its trajectory deviation in two columns of rail surface 180. The location ( m) 。 7. Bearing damage and countermeasure of rolling bearing, if there is no error and can be used correctly, the bearing life before, but with a long period of time, in this case, the damage status to divest. On the other hand, there are early damage by accident, and yield to the early damage of use, as the reasons of early damage, not enough to use and the consideration on the lubrication and, in turn, and foreign invasion, the error of the bearing assembly and axis deflection of big, not enough research on shaft and bearing box and so on, can say, these reasons the situation more overlap each other. So, want to use machine to fully understand the bearing, conditions of use, of the outer bearing structure, on the basis of if we can find out before and after the accident situation, again according to the damage of the bearing and a variety of reasons, can prevent the similar accidents from happening again. 7. 1 - 7. 18 shows examples of bearing damage and the reasons and countermeasures, as concluded that the cause of bearing damage data, please use them. In addition, when analyzing damage, please review schedule 'injury list'.
