Calibration structure and detection method of bearing internal load distribution

Abstract

The invention provides a bearing internal load distribution detection structure, a calibration structure and a detection method. The detection structure comprises 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; strain gauges are pasted on the outer surface of the outer ring of the outer ring of the test bearing, 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 bearing area 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 bythe 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 then the calibrated test bearing and the bearing seat for testing are installed on a working site for a strain distribution test; the processor collects the strain distribution condition of the outer surface of the outer ringof the test bearing, so the internal load distribution of the test bearing is calculated.

Description

technical field [0001] The invention relates to a structure and a method for testing the internal load distribution of a bearing, in particular to a structure and a method for testing the internal load distribution of an in-position 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 load distribution inside the bearing has a great influence on the running state of the bearing. The load distribution 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 load distribution inside the bearing is one of the most important operating characteristics of the bearing. Therefore, understanding the internal load distribution of the bearing during the actual mechanical work has a very positive effect on detecting the ope...
