Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As depicted in figs. 1 and 2, the present invention is a kind of bearing pressure load test equipment, including a support, in support
A bearing fixed seat is fixedly arranged in the middle of, the fixed axis of the bearing fixed seat are parallel with the stage surface of support, in institute
State and a torsion tester is fixed with bearing fixed seat, an axle is fixed with the torsion input shaft of the torsion tester
Hold inside casing binding clasp；
The both sides of corresponding shaft bearing fixed seat are symmetrically arranged with track bar mechanism on objective table；
The track bar mechanism includes a threaded block for being fixed on stage surface and one is slidably connected with stage surface
Pushing block, be connected through a screw thread a push rod on the threaded block, the pushing block includes one and is rotatablely connected with push rod
Distance rod and one and the drive block of distance rod elastic connection, pass through a diastole ring spring bullet between the distance rod and drive block
Property connection, be provided with the drive block one cylinder slide cavity, it is described slip cavity bottom be provided with one
The sliding eye being slidably connected with distance rod outer wall, limited block of the diameter more than sliding eye is additionally provided with thrust boom end,
Drive block promotes pushing block to be moved in stage surface；
Two motor cabinets are also symmetrically arranged with the top of the support, the motor cabinet includes a guide rails, described
The axis of guide rails is vertical with stage surface, and a motor fixed block is slidably connected in the guide rails, described
Motor is perpendicularly fixed on motor fixed block, passes through two between the axial both sides of the motor fixed block and the both ends of guide rails
Individual spring connection；
A driving wheel is provided with the output shaft of the motor, a traction wheel is rotatably connected on the pushing block, is led
Running wheel is double layers table shape structure, including a test wrapper and a drive pulley, is passed through between the drive pulley and driving wheel
Belt transmission connects, and the rubbing surface that test ring surface is provided with rubber mass is used to contact with bearing case surface.
In use, bearing is fixed on torsion tester by bearing bearing inside casing binding clasp, while start motor, lead
Running wheel rotates under the driving of driving wheel, then promotes the traction wheel of the left and right sides respectively by push rod so that traction wheel
On test wrapper contacted with bearing housing surface, while motor moves down under the pulling of belt wheel, so as to prevent belt wheel tension
It is excessive and occur it is damaged so that bearing housing relatively rotates under a fixed load between bearing inside casing, with load
The change of lotus is big, and the contact force between roller and bearing housing, inside casing becomes big, if bearing arrangement existing defects, then bearing is just
It can be failed because load force is excessive, now if the transmission efficiency of bearing is gradually deteriorated, then the local moment of torsion of housing
Bearing inside casing will be passed to by roller, so as to be shown on torque sensor.
