Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in figure 1, simultaneously combining Fig. 4, a kind of experimental rig of no inner-ring bearing, described experimental rig includes experiment
Axle 1, axle sleeve 2, back-up ring 3, test bearing seat 4, test bearing 5 and end cap 6；The inner ring raceway of test bearing 5 inlays interior using axle
Circle mode is operated, and bearing outer ring coordinates with test bearing seat 4；Radial load is applied to load bearings by loading piston,
Connect on effect and test bearing；Described experiment axle 1 is multi-diameter shaft, and its one end is connected as drive end with motor；It is described
The other end of experiment axle 1 is equipped with the axle sleeve 2 with its interference fit, and the external diameter of the axle sleeve 2 is the internal diameter phase with test bearing 5
Kiss is matched somebody with somebody；The structure of axle sleeve is as shown in figure 3, the experiment axle 1 is supported in the endoporus of test bearing 5 by axle sleeve 2, and conduct is tried
Test the inner ring of bearing.
As shown in Fig. 2 the experiment axle includes cylindrical section I 7, cylindrical section II 8, cylindrical section III 9 and the circle for setting gradually
Cone section 10；Described cylindrical section I 7 and the interference fit of axle sleeve 2；The cylindrical section II 8 it is straight
Diameter of the footpath more than cylindrical section I 7；The diameter with diameter greater than cylindrical section II 8 of the cylindrical section III 9；Described circle
Cone section 10 coordinates with described motor.
When the utility model is processed：The experiment shaft material of mounting sleeve non-first selects 40Cr modifier treatment, processing dimension
ForMm, heat treatment hardness HRC58-62;Then axle sleeve processing is carried out, axle sleeve is used and bearing outer ring identical steel alloy
9310VARAMS6265 materials, internal diameter size isMm, outside dimension isMm,；Experiment axle and axle sleeve are carried out
It is processed after cooperation, wants super grinding when axle sleeve is engaged rear axle housing external cylindrical surface with experiment axle, it is ensured that its precision, external cylindrical surface
For interior raceway must not damage；It is connected with motor after bearing is assembled, completes the debugging of this experimental rig.
Bearing tester main body is single shaft architecture, the groundwork such as the installation stress form of bearing and lubrication form structure
Condition is basically identical with this test bearing actual condition.
Splash lubrication is using simulation splash lubrication mode.Spilled oil end cap is initially entered after lubricating oil is heated, by spilled oil end
Lid enters disc, and lubricating oil is thrown away and be simulated splash lubrication to bearing by disc with bearing rotary.
