A kind of bearing roller plastic deformation experiment device and using method thereof

Abstract

The invention provides a bearing roller plastic deformation experiment device and a using method thereof. The device comprises a roller base and a bottom plate; a left side guide supporting mechanismand a right side guide supporting mechanism are fixed to the left side and the right side of the bottom plate; the left and right side guide mechanisms are guide rail-slider mechanisms; the sliders ofthe left and right side guide mechanisms are fixed to the left end and the right end of a lifting cross beam; the upper side of the lifting cross beam is connected to one end of a pressure sensor; the upper end of the pressure sensor is connected with a lifting drive mechanism; the lifting cross beam is in hinged joint with a pressure plate; the pressure plate is in rotatable connection with a contact plate; a positioning mechanism of the contact plate is arranged; the contact plate is cross-shaped; one side of the cross is provided with a protruding plate extending out downward; the protruding plate is in clearance fit with a calibration notch in the roller base; another side of the cross-shaped contact plate is used for loading and pressing a roller. With an electric push rod and the pressure sensor, automation of pressure adjustment and pressure loading processes is realized.

Description

technical field [0001] The invention relates to a bearing roller experimental device and a using method thereof, in particular to a bearing roller plastic deformation testing device and a using method thereof. Background technique [0002] The current bearing test machine usually fixes the bearing on the test bench and rotates it after loading. Since the bearing is an assembly component, the processing error and assembly error of the component will affect the deformation of the entire bearing roller, so it cannot be objectively reflected. The actual deformation of the roller after being loaded, even if there are some devices that conduct deformation experiments on the roller alone, it needs to add test rollers, which cannot reflect the deformation of a single roller well. [0003] During the operation of the roller bearing, the roller rotates on its own and revolves along the inner ring of the bearing. In some occasions, when the thrust bearing is used on equipment with low ...
