Bearing temperature measuring probe fixing device

Abstract

The invention provides a bearing temperature measuring probe fixing device, which is used to be installed in a mounting hole of a bearing seat, the mounting hole is a stepped hole, and the bearing temperature measuring probe fixing device includes an elastic clamp for clamping the temperature measuring probe. The clamping structure, the support seat for supporting the clamping structure and the clamping structure for compressing the clamping structure; wherein the clamping structure has an installation through hole for piercing the temperature measuring probe, and the temperature measuring probe The bottom end is in contact with the outer surface of the bearing ring; the support base is fixed at the step in the installation hole, and the clamping structure is fixed on the support base; the clamping structure is pressed tightly on the clamping structure to apply clamping measurement to the clamping structure temperature probe pressure. The fixing device is installed in the mounting hole of the bearing seat, and there is no need to open holes on the equipment at the outer end of the bearing seat, so the installation is simple and convenient; the bottom end of the temperature measuring probe is always in contact with the outer surface of the bearing ring for real-time measurement The temperature of the outer surface of the bearing ring.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a fixing device for a bearing temperature measuring probe. Background technique [0002] Aviation rolling bearings are one of the core components of aviation turboshaft engines. They have the characteristics of high speed and high temperature. In order to reduce weight, most of them adopt light structures with thinner ring walls. In the bearing test and engine test, in order to ensure the safety of the test, the working temperature of the bearing needs to be strictly controlled, so the surface temperature of the stationary ring of the bearing must be monitored in real time. [0003] The measurement sensor of the surface temperature of the stationary ring of the bearing is similar to the measurement method of the solid surface temperature, but requires reliable temperature measurement and a fast temperature response speed. Based on experience, bearing temperature measurements using thermo...
