Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a load equalization detection device and detection method of a series combined thrust bearing, which eliminates the fact that the prior art device can only test the rotating speed, vibration noise and fatigue life test Insufficient, so that it can apply tens of kilonewtons or even higher axial load, and can test the actual load of each stage bearing in the tandem combination thrust cylindrical roller bearing in the rotating working state, thus changing the existing various types The technical limitations of bearing testing methods and test devices meet the special performance testing requirements required for the structure of tandem combined thrust cylindrical roller bearings

Abstract

The present invention belongs to bearing detection and test in mechanical engineering and is the load uniforming detection device and method for serial combined thrust bearing. There are vertical frame, oil cylinder in the lowr part, driving box in the upper part with thrust bearing on its output shaft, bearing fixing seat screwed to the output end of oil cylinder piston rod; serial combined cylindrical roller thrust bearing to be set in the bearing fixing seat and with spindle connected to the output shaft; speed varying gear mechanism inside the driving box; and electrical resistance strain gages to be adhered to the outer surface of the bearing to be measured. The present invention has the features of reasonable structure and reliable measured data and is suitable for dynamic detection of uniform load performance and fatigue life of various serial combined cylindrical roller thrust bearings.

Description

technical field [0001] The invention relates to a bearing performance detection device and a detection method thereof, in particular to a series combined thrust bearing load sharing detection device and a detection method thereof, belonging to the field of bearing detection and testing in mechanical engineering. Background technique [0002] Series combined thrust cylindrical roller bearing is a thrust bearing group with small radial size and large load capacity, which consists of several identical non-standard thrust cylindrical roller bearings and cylindrical inner spacers and outer spacers between them. Constructed in series, the inner spacer ring is located between the adjacent shaft rings of the thrust bearing group, and the outer spacer ring is located between the adjacent seat rings of the thrust bearing group. Each thrust cylindrical roller bearing should be able to share the bearing of the total shaft This is the key to the large load capacity of the thrust bearing ...
