Description

TECHNICAL FIELD

[0001] The utility model relates to bearing test technical field, concretely is a bearing test axle temperature detection device. BACKGROUND

[0002] Bearing is an important spare part in contemporary mechanical equipment. Its main function is to support mechanical rotary body, reduce its friction coefficient in the movement process, and ensure its rotation precision, the life of the rolling bearing is defined by the number of revolutions (or by the working hours under a certain speed): within this life, the bearing should have initial fatigue damage (peeling or defect) on any bearing ring or rolling body. However, whether in laboratory test or in actual use, it can be obviously seen that the actual life of the same appearance bearing under the same working condition is quite different. In addition, there are several different definitions of bearing "life".
