The utility model purpose is to provide a kind of mounting structure of measuring the thermopair of bearing outer ring temperature, measures the bearing outer ring temperature to solve prior art, with the technical matters of thermocouple welding at its complicated operation of bearing outer ring.
For achieving the above object, according to an aspect of the present utility model, a kind of mounting structure of measuring the thermopair of bearing outer ring temperature is provided, be used for installing and measuring the thermopair of temperature, comprise installation shaft, be installed in bearing on the installation shaft and the bearing seat of solid bearing, the side of bearing seat is provided with and interts the through wires hole of thermopair, and the sidewall of bearing seat is provided with the mounting hole that communicates with through wires hole, mounting hole is through hole, the outer ring of the top contact bearing of thermopair.
Further, mounting hole is threaded hole, and a housing screw is installed in the mounting hole, and housing screw compresses the top of thermopair.
Further, the head of housing screw has groove.
Further, the distance of the center line distance between bearing outer ring of through wires hole is 2.5 ~ 3.5mm.
Further, the center line of the rolling body of the center line of mounting hole and bearing is on same straight line.
Further, mounting structure also comprises bearing gland, bearing gland contact bearing and bearing seat.
The utlity model has following beneficial effect:
The mounting structure of the thermopair of measurement bearing outer ring temperature of the present utility model adopts housing screw to compress the mode of thermopair, installs simple, convenient; After the assembling of bearing and bearing seat is finished, thermopair is installed again, can be reduced the broken string phenomenon in assembling process; Even change thermopair, also only need unclamp housing screw, the thermopair that again interts gets final product, and saves the working time; This mounting structure does not affect the mission life of bearing to the not impact of surface of bearing outer ring.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
