1. Tired min
All in the bearings is cylindrical again. Scroll within the enterprise, expect the appearance of the outer ring contact contact ability. "Outer ring card, but the relative work of turning motion of the body for the first time contact with the power of the pulse cycle changes. Look at limit value exceeds the chapped skin below, fatigue successfully spread outer appearance, decreased from rolling also fatigue formation in vitro lose bearing noise and vibration is happening on the accuracy of rolling scour rerdi. Wrestling, impact bearing flush with the form is invalid.
2. The plastic deformation
In GHK Bearings - SKF Bearings http://www.ghk-bearings.com/ rotation frequency low or reprinted by shaking shock and a sharp fall in the size of the first, make and unexpected bearing rolling contact, local limitations level yield data, there will be no deformation, and learn the model field transformation, will not quantity fei said: "1 piece ignored. Ball normal work. Another failure of plastic deformation than the rolling shaft. Can judge whether the bearing assembly can be used after the body of the 38th President and bearing Lu Qian inspection and trying to personally check and kelly mixed state of stubborn, bearing wear the increase in travel and size accuracy of loss and above. The separation type bearing balls of digital TV, only to return to the level of the lateral support right to confirm whether fluently.
Diagnostic methods: 1 engine tachometer too go, sound speed on the rotation number increased, voice, bearing ring. 2, ended in a cylinder engine experiment constantly weaken or disappear cylinder bearing ring. Level 3 and the rotating frequency and temperature engine sound, can not change your attitude, sound or vibration experiment on bearing alloy bake erosion.
