Description
Technical field
The utility model relates to a kind of rubbercushioned sleeve bearing coupling, especially a kind of easily changeable rubbercushioned sleeve bearing coupling.
Background technique
When some only can change pin from wherein one end of coupling, elasticity of the prior art is entangled pin coupling and can not be met the demands.
Portioned product has made improvement, such as Chinese patent discloses a kind of quick changing type rubbercushioned sleeve bearing coupling, application number: 201410154128.3, the applying date: 2014-04-17, comprise right half-coupling, pin, elastic sleeve and nut, described right half-coupling is provided with the pin-and-hole worn for described pin, sliding sleeve is provided with between described pin and pin-and-hole, the external diameter of described sliding sleeve is not less than the external diameter of described elastic sleeve, the right cap of described sliding sleeve is provided with the pressing plate be connected with described right half-coupling, is spirally connected after the right-hand member of described pin stretches out described pressing plate with described nut.In the present invention, the external diameter of sliding sleeve is slightly larger than the external diameter of elastic sleeve, unclamp nuts and bolt, pressing plate, sliding sleeve, pin and elastic sleeve can be pulled down from the right of coupling together, are convenient to the replacing of elastic sleeve, do not need after replacing again to correct coaxality, enhance productivity.
This technological scheme still Problems existing is, after unclamping nut, bolt, pressing plate, sliding sleeve possibly cannot pull out with pin, and may be bonded together with elastic sleeve and be difficult to take out.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of rubbercushioned sleeve bearing coupling being easy to remove and install pin.
The technical solution of the utility model is:
A kind of easily changeable rubbercushioned sleeve bearing coupling, comprise left half-coupling, right half-coupling, elastic sleeve, pin, it is characterized in that: described left half-coupling is corresponding with right half-coupling to be arranged, left half-coupling is provided with blind hole, right half-coupling is provided with through hole, blind hole and lead to the hole site corresponding matching are arranged, its effect is that pin can only be mounted and dismounted from right half-coupling, described pin runs through through hole and inserts blind hole, described pin overlaps flexible cover outside blind hole one end and outside the described pin the other end, cover has sliding sleeve, the ratio of the length of described elastic sleeve and the length of sliding sleeve is 3:1, the external diameter of described sliding sleeve is not less than the external diameter of described elastic sleeve, described through hole hole place is provided with the pressing plate by screw and nut compressing, its effect compresses sliding sleeve, the part that described pin exposes through hole hole is connected with bolt, described sliding sleeve is provided with some micelle projections towards one end end face of blind hole, described sliding sleeve is provided with the sucker of indent towards one end end face at through hole hole, its effect produces elastic potential energy by micelle projection and elastic sleeve end face, energy automatic spring when pressing plate is dismantled time, also hold pressing plate by sucker in addition, along band, sliding sleeve is pulled out when pressing plate is dismantled time, thus the problem that when solving pressing plate dismounting, sliding sleeve can not pull out together with pin.
Further, outside described elastic sleeve, be provided with a plurality of trapezoidal grooves vertically, increase elastic deformation amount.
Further, described pressing plate is ring-type.
Further, described micelle projection is half elliptic projection, and its effect ensures enough deformation quantities and has enough intensity.
Further, described sucker is the groove of indent on sliding sleeve end face, and groove is hemispherical and groove notch is provided with flange, strengthens adsorption effect further.
The beneficial effects of the utility model are: the utility model structure is simple, elastic potential energy is produced by micelle projection and elastic sleeve end face, energy automatic spring when pressing plate is dismantled time, also hold pressing plate by sucker in addition, along band, sliding sleeve is pulled out when pressing plate is dismantled time, thus the problem that when solving pressing plate dismounting, sliding sleeve can not pull out together with pin.
