The rolling bearing shakes the simple theory of the tester


30th September 2010 Bearing Technology 0 Comments
First. The rolling bearing shakes the basic principle The vibration of the rolling bearing is a very complicated random mechanical phenomenon. Up until now, the total bearing shakes the theory and has not set up yet, it is one of the generally acknowledged still unripe bearing basic theories that the bearing shakes the theory. Shake since a kind of quality judges the standard, according to it, can divide the grade for the bearing quality, it is a kind of quality control means in the manufacture process of the bearing to shake. In the field of bearing, the low technology of shaking the bearing ...

Improve the craft measure that one set of circles quenches quality of GCr15 steel bearing


30th September 2010 Bearing Technology 0 Comments
The common defect expands the craft when first, the intersection of bearing and suits of lap quench and cool The part of the bearing adopts the oil as quenching mediums extensively, the main reason is the third stage convection one of the oil in the course of cooling The cooling speed is very slow. It is 20~50 ℃/ s when the 10th when use in past production, machinery oil No. 20 are among 650~500 ℃. Unless begin since 300 ℃ probably convection issues of stage, keep sustaining until by room temperature,just and the horses of bearing steel body be required speeds cooleds smaller not to be ...
