Effect of Grease Lubrication on the Nonrepetitive Runout (NRRO) in Ball Bearing

Blog Article

Nonrepetitive runout (NRRO) is mainly caused by the diameter differences of balls contained in a bearing and the form errors of the raceway and balls.This paper deals with the effect of grease lubrication on NRRO.The results can be eagles laptop case summarized as follows.(1) NRRO in the case of grease lubrication was larger than that in the case of oil lubrication.(2) The rotational frequency andre 3000 new blue sun zip of cage increased with the increment of unbalance or rotational speed.

In the rotational accuracy on the level of one nanometer, it was clarified that the lubricant was a very important factor in a ball bearing.
