Testing method of internal radial clearance of bearing

Abstract

The invention provides a method for detecting a radial working clearance in a bearing. The device is provided with a test bearing and a test bearing seat matched with the outer ring of the test bearing. A plurality of grooves are formed in the inner surface, corresponding to the bearing area of the test bearing, of the test bearing seat, and strain gauges are pasted on the outer surface of the outer ring of the outer ring of the test bearing, wherein the number of the grooves and the number and positions of the strain gauges correspond to the number and positions of the rollers in the bearingarea of the test bearing, and the strain gauges are connected to a processor capable of collecting strain changes. The inner ring of the test bearing is replaced by the calibration shaft sleeve to carry out a calibration experiment. And finally, the calibration shaft sleeve is replaced by an original inner ring of the test bearing, and the calibrated test bearing and the calibrated test bearing pedestal are installed on a work site for strain distribution test; the processor collects the strain distribution condition of the outer surface of the outer ring of the test bearing, the internal loaddistribution of the test bearing can be calculated, and finally the internal radial work clearance of the bearing is obtained through derivation.

Description

technical field [0001] The invention relates to a detection method for measuring the internal radial clearance of a bearing, in particular to a detection method for the internal radial clearance of an in-position running bearing. Background technique [0002] Bearing is an important component of various construction machinery transmission systems, and its operating status directly affects the use of related construction machinery. The internal clearance of the bearing has a great influence on the running state of the bearing. For bearings subjected to radial loads, the radial clearance inside the bearing plays a very important role in bearing stiffness, load capacity, fatigue life, vibration and dynamic response, etc. It can be said that the radial clearance inside the bearing It is one of the most important operating characteristics of a bearing. Therefore, understanding the internal radial clearance of the bearing during the actual mechanical working process has a very p...
