In the middle of prior art, the frame of bearing tester is provided with turning axle, the swiveling wheel that axle center is test bearing mounting hole is rotatably connected in mount pad, mounting hole setting corresponding with turning axle free end, groove is provided with in the middle of swiveling wheel, groove is hung with wire rope, through the guide hole being located at mount pad middle lower portion, the wire rope lower end being located at the guide hole in the middle of slide plate is hung with pulling force sensor, the slide plate two ends of sliding in frame are connected with the sliding bar be fixed in frame, mount pad is placed on slide plate, the wire rope that pulling force sensor lower end connects is wrapped in pressuring shaft after being rotatably connected on the angle sheave guiding in frame, the pressuring shaft end be connected with gantry rotation is provided with pressurized handgrip.During testing machine work, test bearing is arranged in mounting hole, moving mount pad and slide plate together makes turning axle free end insert in bearing, and starter motor makes turning axle rotate, then shakes pressurized handgrip and carry out grinding test to test bearing increase load to test bearing by wire rope.Swiveling wheel is under the lower pulling force effect of wire rope, friction force between swiveling wheel and bearing, between mount pad increases and is directed at swiveling wheel and can not rotates, the test bearing be located in mounting hole also can not rotate because friction force increases, the pressure born due to test bearing top is maximum, causes the grinding great efforts between the top of test bearing and turning axle.Can not regularly convert owing to test bearing bearing the large grinding part of pressure, the dynamics that other position of test bearing is ground is less than normal comparatively speaking, the degree of grind at each position on test bearing will be caused like this to occur inconsistent phenomenon, directly affects bearing test effect.
Summary of the invention
The technical matters that the present invention solves is to provide and a kind ofly can makes the bearing tester that on test bearing, each position degree of grind is consistent.
Technical scheme of the present invention is the bearing tester completed like this, include mount pad, pulling force sensor, frame, slide plate, slide bar, wire rope, angle sheave, pressure axis, the swiveling wheel that axle center is test bearing mounting hole is rotatably connected in mount pad, putting above has the slide plate two ends of mount pad to be connected with the sliding bar be connected in frame, mount pad middle lower portion, guide hole is equipped with in the middle of slide plate, the wire rope being fixed on pulling force sensor lower end is wrapped in the pressuring shaft that is rotatably connected in frame after being rotatably connected on the angle sheave guiding in frame, groove is provided with in the middle part of swiveling wheel, also comprise U-shaped frame, motor, chain, be provided with in described groove by movable sprocket, be fixed on the loading axle on U-shaped frame and be rotatably connected to drive sprocket and passive crowngear, drive sprocket and passive crowngear are fixed together, chain through guide hole links together by drive sprocket with by movable sprocket, be suspended on bottom the U-shaped frame below slide plate and be fixed with motor, be connected in active crowngear on motor output shaft and passive crowngear meshes together, motor lower end is connected with pulling force sensor upper end.
Further preferred embodiment, described motor is variable-frequency motor, and variable-frequency motor is electrically connected with the frequency converter be fixed in frame.
Further preferred embodiment, described pressure axis end is provided with pressurized handgrip.
Technique effect of the present invention is, when being worked by the present invention motor can by crowngear, drive sprocket, chain, by movable sprocket driven rotary wheel rotate, swiveling wheel motoring ring test bearing rotates to the direction that turning axle is contrary, test bearing is made to follow swiveling wheel to rotate together, in spin finishing process, make to bear the continuous regular conversion in the maximum test bearing position of pressure, thus ensure that the consistance of each position degree of grind on test bearing, ensure that the test effect of test bearing.
