In figure: 1. hydraulic jack, 2. on bracer, 3. screw thread protection cap, 4. handrail, 5. gusset, the most lower bracer, 7.
Motor side half is to wheel, and 8. pin, 9. nut, 10. spring shim, 11. resilient sleeve, 12. pump sides half are to wheel.
Detailed description of the invention
A kind of coupling pin provision for disengagement proposed the present invention with embodiment below in conjunction with the accompanying drawings is carried out further
Introduce:
A kind of coupling pin provision for disengagement, is used for dismantling elastic dowel pin shaft coupling, and this shaft coupling includes that motor side half is right
Wheel 7, pump side are partly to wheel 12, and pump side half is provided with through hole to wheel 12, and motor side half is to taking turns 7 taper holes being provided with 1:10, and pin 8 is worn
Cross the pump side half through hole to taking turns on 12 and the motor side half taper hole to taking turns on 7, through motor side half, one end of wheel 7 is screwed with nut
9, nut 9 and motor side half are provided with spring shim 10 to taking turns between 7 contact surfaces；Pin 8 at pump side half to taken turns in 12 through holes
End is peripherally equipped with resilient sleeve 11, it is characterised in that: described coupling pin provision for disengagement includes hydraulic jack 1, above props up bracer
2, screw thread protection cap 3, handrail 4, gusset 5 and lower bracer 6 are wherein, above prop up bracer 2 and lower bracer 6 is connected by gusset 5,
Gusset 5 is provided with two handrails 4, is provided with hydraulic jack 1, is provided with screw thread on the downside of hydraulic jack 1 on the downside of described upper bracer 2
Protective cap 3.
Described lower bracer 6 is provided with through hole, and the diameter of this through hole is more than the pump side half through-hole diameter to wheel 12.
Described screw thread protection cap 3 endoporus is machined with the screw thread identical with pin 8, and is machined with escape.
