Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
the device comprises a measuring mounting seat, a power supply, a connecting stud, a bearing, a screw and an avoidance groove, wherein the measuring mounting seat is 1, the power supply is 2, the connecting stud is 3, the bearing is 4, the screw is 5, and the avoidance groove is 6.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below.
As shown in fig. 1, a bearing conduction measurement device, including measuring mount pad 1, be provided with power 2 in measuring mount pad 1 outside, the anodal and negative pole of power 2 are connected with connecting stud 3 respectively through the wiring, it has the threaded connection hole to measure mount pad 1 both sides processing, and connecting stud 3 is connected with the threaded connection hole respectively, it has annular mounting groove to measure the processing in the mount pad 1, and annular mounting groove is used for installing bearing 4, and wherein, bearing 4 adopts transition fit with annular mounting groove, makes bearing 4 closely laminate with annular mounting groove lateral wall, ensures that the bearing is electrically conductive completely in the conduction test process.
Four detachable screws 5 are arranged at the bottom of the annular mounting groove, the four screws 5 are uniformly distributed along the annular mounting groove, and after the conduction test, if the bearing 4 is too tightly matched with the annular mounting groove, the bearing 4 can be lifted out of the annular mounting groove by screwing the screws 5.
The periphery of the bottom of the annular mounting groove is provided with an inward concave avoidance groove 6, interference is prevented by the avoidance groove 6, and the bearing 4 is prevented from being mounted in place.
In the conduction test process of the bearing, a connecting stud is firstly connected into a threaded connecting hole of a measurement mounting seat, a power supply is electrified, a first voltage between the side walls of an annular mounting groove is measured, then the power supply is turned off, the bearing is mounted in the annular mounting groove, the power supply is turned on again, a second voltage between a point a of an outer ring of the bearing and a point b of an inner ring of the bearing is measured, the point a and the point b are points abutted against the side walls of the annular mounting groove, if a numerical value between the second voltage and the first voltage changes, the conduction of the bearing is indicated, and if the numerical value between the second voltage difference and the first voltage difference does not change, the non-conduction of the bearing is indicated.
The utility model is not limited to the embodiments described, but a person skilled in the art may make modifications or changes without departing from the spirit of the utility model, i.e. the scope of the disclosure, and the scope of the utility model is defined by the claims.
