Radial loading device of multifunctional bearing testing machine

Abstract

The invention discloses a radial loading device of a multifunctional bearing testing machine. The radial loading device comprises a bottom plate, a guide rail, a radial loading base, an axial guide base, a loading cylinder installation base, an installation base location pin, an installation base connection bolt, an installation base T-shaped locking bolt, an axial loading cylinder, a front guideseat, a coupler, a pressure sensor, a rotation stop pin, a force applying shaft, a bearing test installation tool, a tool connection bolt, a sensor installation assembling body and a front guide basefixed T-shaped bolt. The present invention relates to a combined type rolling bearing life test machine, concretely a radial loading device of a multifunctional bearing testing machine cooperative with the axial loading tool and an inclined loading tool to complete applying of three different loads for the test bearing, and the radial loading device of the multifunctional bearing testing machine can apply radial loads in two modes of pulling or pressing for the test bearing, and is convenient and rapid in loading, simple to operate, convenient to maintain and convenient to dismount and mount.

Description

technical field [0001] The invention belongs to the field of bearing testing machines, and relates to a composite rolling bearing life testing machine, in particular to a radial loading device for the composite equipment. Background technique [0002] Rolling bearings are one of the most widely used mechanical parts, and they are also one of the most easily damaged components in mechanical equipment, especially rolling bearings under high-speed and heavy-load conditions. Fatigue, cracks, erosion, indentation and other faults, which will cause the bearing to break, glue, burn, etc., and then cause the abnormality of the entire equipment. [0003] Therefore, the life test before leaving the factory for rolling bearings can not only improve the production process of the bearings, but also guide the timely replacement of the bearings used on the equipment. At present, there are few bearing testing equipment for bearing life testing that can satisfy axial loading, overturning lo...

AI Technical Summary

Problems solved by technology

At present, there are few bearing testing equipment for bearing life testing that can not only satisfy axial loading, overturning loading and radial loading, but also withstand high-speed and heavy-load conditions.
