Railway wheelset rolling bearing running-in machine pneumatic wheelset pressing and positioning mechanism

Abstract

The invention provides a railway wheelset rolling bearing running-in machine pneumatic wheelset pressing and positioning mechanism which comprises a clamping wheel seat, a pressing wheel mechanism andan infrared temperature measuring probe, the clamping wheel seat is of a right-angle structure, and the pressing wheel mechanism is arranged at the end of a horizontal rod of the clamping wheel seatand used for limiting the position of a wheelset; the pressing wheel mechanism comprises a hydraulic rod and a wheel clamping block, the bottom of the hydraulic rod is connected with the wheel clamping block, the middle of the bottom of the wheel clamping block is of an arc-shaped structure, and the infrared temperature measuring probe for detecting the surface temperature of the wheel set bearingis arranged on the arc-shaped surface of the bottom of the wheel clamping block. The mechanism has the advantages that the clamping wheel block in the pressing wheel mechanism presses the bearing andis positioned on a limiting seat and the bearing is limited, so that , the position of the bearing on the wheel set is stable in the rotating process of the wheel set, and when the wheel clamping block is attached to the wheel set to limit the bearing, the infrared temperature measuring probe on the wheel clamping block is attached to the surface of the bearing of the wheel set, so that temperature detection of the bearing is more accurate.

Description

technical field [0001] The invention relates to the technical field of production and maintenance of railway rail transit equipment, in particular to a pneumatic wheel set pressing and positioning mechanism of a railway wheel set rolling bearing running-in machine. Background technique [0002] The bearing running-in machine is composed of computer automatic control system, pneumatic system, wheel set tread drive, bearing positioning system and other parts, and the bearing running-in process is fully automated. Through computer control, during the running-in process of the bearing, the temperature rise change of the bearing is input to the industrial computer through the signal collected by the infrared temperature measuring probe, and then processed by the microcomputer, the temperature rise curve of the bearing running-in is displayed on the computer screen, so that the bearing is The temperature rise change during the running-in process is very intuitive and clear at a gl...

Problems solved by technology

[0003] The bearing running-in machine currently used only places the bearing of the wheel set on the limit seat, and does not limit the position of the bearing. The infrared temperature measuring probe is located on the side of the bearing. During the rotation of the wheel set, the position of the bearing is prone to vibration. On the one hand The effect of running-in is good, on the other hand, the temperature detected by the infrared temperature measuring probe is not accurate, and the use effect is not good
