Description
Technical field
This utility model relates to a kind of oscillating bearing no-load starting moment test fixture.
Background technology
Oscillating bearing needs to test its staring torque, is installed in experimental machine by oscillating bearing by fixture during test. But oscillating bearing can be applied load radially by the fixture of prior art, affects experimental precision.
Utility model content
The purpose of this utility model is in that to overcome above shortcomings in prior art, and provides the oscillating bearing no-load starting moment test fixture that a kind of reasonable in design, precision are high.
The technical scheme in the invention for solving the above technical problem is: a kind of oscillating bearing no-load starting moment test fixture, it is characterised in that: include left handed twist seat, left outside circle jacking block, support bar, inner ring jacking block, right outer ring jacking block, gripper shoe, right torsion seat and right axis; The lateral surface of left handed twist seat is fixed with left clamping bar; Left outside circle jacking block is fixed on left handed twist seat; The end of left outside circle jacking block has the left end face of annular; Support bar one end and left handed twist seat are fixed, and the other end and gripper shoe are fixed; Right torsion seat is threadeded fixing with gripper shoe; The end of right torsion seat has the right end face of annular, left end face and right end face and is oppositely arranged; Inner ring jacking block is two pieces, is threaded in right axis; The outer end of right axis is fixed with right clamping bar.
The left clamping bar of this utility model, left handed twist seat, left outside circle jacking block, inner ring jacking block, right outer ring jacking block, gripper shoe, right torsion seat, right axis, right clamping bar are coaxially disposed.
This utility model is provided with screens ledge structure in the contact position of left handed twist seat and left outside circle jacking block.
The cross section of the left clamping bar of this utility model is just hexahedro shape.
The cross section of the right clamping bar of this utility model is square.
This utility model compared with prior art, has the following advantages and effect: reasonable in design, by axial clamping force fixing joint bearing, oscillating bearing will not be applied load radially, without influence on experimental precision.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following example are that this utility model is not limited to following example to explanation of the present utility model.
Referring to Fig. 1, this utility model embodiment includes left handed twist seat 1, left outside circle jacking block 2, support bar 3, inner ring jacking block 4, right outer ring jacking block 5, gripper shoe 6, right torsion seat 7 and right axis 8.
The lateral surface of left handed twist seat 1 is fixed with left clamping bar 9. The cross section of left clamping bar 9 is just hexahedro shape.
Left outside circle jacking block 2 bolt 10 is fixed on left handed twist seat 1.
The contact position of left handed twist seat 1 and left outside circle jacking block 2 is provided with screens ledge structure 11, it is ensured that concentricity.
The end of left outside circle jacking block 2 has the left end face 12 of annular.
Support bar 3 one end is fixed with left handed twist seat 1, and the other end is fixed with gripper shoe 6, left handed twist seat 1 and gripper shoe 6 is fixed together.
Right torsion seat 7 is threadeded fixing with gripper shoe 6, so directly can assemble with hands, does not need instrument can realize installing sample.
The end of right torsion seat 7 has the right end face 13 of annular, and left end face 12 and right end face 13 are oppositely arranged.
Inner ring jacking block 4 is two pieces, is threaded in right axis 8.
The outer end of right axis 8 is fixed with right clamping bar 14. The cross section of right clamping bar 14 is square.
Left clamping bar 9, left handed twist seat 1, left outside circle jacking block 2, inner ring jacking block 4, right outer ring jacking block 5, gripper shoe 6, right torsion seat 7, right axis 8, right clamping bar 14 are coaxially disposed, it is ensured that concentricity.
During test, being enclosed within right axis 8 by the inner ring of oscillating bearing 15, and between two pieces of inner ring jacking blocks 4, two pieces of inner ring jacking blocks 4 screw relatively, the inner ring of oscillating bearing 15 is withstood fixing by two pieces of inner ring jacking blocks 4, and at this moment clamping force is axial. Then will be equipped with the right axis 8 of oscillating bearing 15 and put on left outside circle jacking block 2, by right torsion seat 7 precession gripper shoe 6. The outer ring of oscillating bearing 15 is between left end face 12 and right end face 13, and the outer ring of oscillating bearing 15 is withstood fixing by left end face 12 and right end face 13, and at this moment clamping force is axial. Then this utility model is put in experimental machine, the rotating disk of left clamping bar 9 and test machine is fixed, the fixing seat of right clamping bar 14 and test machine is fixed, the left clamping bar 9 of driven by rotary disc of test machine rotates, and right clamping bar 14 is fixing, the inner ring of such oscillating bearing 15 is fixed and outer ring rotating, thus tests the staring torque of oscillating bearing 15.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of its parts and components, be named title etc. can be different, and the above content described in this specification is only to this utility model structure example explanation.
