SKF bearing vibration analysis of the impact on the accuracy of universal joint

Bearing use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to SKF bearing installation, use, maintenance, maintenance of technical requirements, the operation of the universal joint bearing of load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. Installation condition is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state of operation and the service life of the early end internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. 1) Bearing design parameters, including the number of rolling element bearings, ring throwing, wall thickness and clearance, etc. 2) Bearing parts manufacturing error: including bearing raceway and rolling body surface roughness, grain degree and the roundness error. A large number of experimental study show that the waviness of SKF bearing vibration influence of dominant, and the influence of surface roughness and the roundness is relatively small. 3) Bearing working conditions: bearing in the process of operation, load, speed, lubrication condition the influence of the three aspects of bearing vibration is the largest. 4) Bearing installation parameters, bearing and shaft and bearing seat, and the bias of installation and other factors also affect the vibration of the bearing. 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 universal joint 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 whether SKF bearing with accidents such as whether the load and the installation error of kingdoms, and shall be investigated for bearing damage and you will become a reason for clues. If there is no error and can be used correctly, the universal joint bearing life before, but with a very long 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, etc. It can be said that these reasons the situation more overlap each other. So, want to use machine to fully understand the bearing, using conditions, SKF bearing periphery, on the basis of the structure of the if we can find out before and after the accident situation, coupled with universal joint bearing damage and a variety of reasons, can prevent the similar accidents from happening again.
