Abstract
The utility model discloses a universal-joint-pin type universal coupler which comprises two jaws and a universal joint pin. Two coaxial through holes are formed in each jaw, four radial shafts of the universal joint pin are respectively inserted four jaw through holes and matched with the four jaw through holes in a one-to-one correspondence mode, a thrust stopping device preventing the radial shaft from sliding in the radial direction is arranged on the radial end portion of each radial shaft of the universal joint pin, the thrust stopping device comprises a pressing plate and a nut provided with outer threads, the pressing plate is U-shaped, and is sleeved on the radial end portion of the radial shaft, steps are formed in the external surface of the U-shaped pressing plate, the nut is arranged on the external surface of the U-shaped pressing plate in a sleeved mode, and the internal end face of the nut abuts against the step face of the U-shaped pressing plate. The nut is arranged on the jaw in a screw mode, and therefore the thrust stopping devices can effectively prevent the universal joint pin from sliding in the radial direction or leaping during the operating process of the coupler, and therefore reliability of the coupler is greatly improved, and the service life of the coupler is further prolonged.
Description
Technical field
The utility model relates to a kind of coupling, is specifically related to a kind of universal coupling with spider.
Background technique
Coupling is two axles that connect in the different institutions, and makes it common rotation to transmit the mechanical parts of moment of torsion.Universal coupling with spider is a kind of coupling commonly used, its structure mainly comprises two jaws and a cross axle, be provided with two coaxial through holes on each jaw, four radial axles on the described cross axle respectively with the corresponding inserting one by one of four jaw through holes, thereby two jaws are linked together by cross axle, two jaws are connected with driven shaft with driving shaft respectively again, to realize the transmission of moment of torsion.But because existing universal coupling with spider, do not arrange between radial axle on it and the jaw through hole and prevent cross axle thrust device in axial sliding, therefore in the coupling running, endwisely slipping or play of cross axle easily taken place, thereby greatly reduce the linkage reliability of coupling, and shortened the working life of coupling.
Summary of the invention
At the deficiencies in the prior art, the utility model provides that a kind of reliability is higher, the universal coupling with spider of longer service life.
For achieving the above object, the utility model provides a kind of universal coupling with spider, comprise two jaws and a cross axle, be provided with two coaxial through holes on each jaw, four radial axles on the described cross axle respectively with the corresponding inserting one by one of four jaw through holes, the axial end portion of every radial axle is provided with one and prevents its thrust device in axial sliding on the described cross axle, described thrust device comprises that a pressing plate and is with externally threaded nut, the described pressing plate structure that takes the shape of the letter U, described U-shaped pressing plate is set on the axial end portion of radial axle, the outer surface of U-shaped pressing plate is provided with step, described nut sleeve is loaded on the outer surface of U-shaped pressing plate, and the step surface butt of the interior edge face of nut and U-shaped pressing plate, the exterior edge face of described jaw through hole is provided with the groove of ccontaining described nut, and the inwall of groove be provided with nut on the internal thread of outside thread bolt.
The utility model can further be set to described thrust device and also include cover plate and screw, and described cover plate press-fits on the exterior edge face of nut, and fixes by screw between described cover plate and the jaw.
The beneficial effects of the utility model are: adopt said structure, because the utility model has been set up between described cross axle and jaw through hole and has been prevented its thrust device in axial sliding, therefore in the coupling running, can prevent endwisely slipping or play of cross axle effectively, thereby improved the reliability of coupling greatly, and then also just prolonged the working life of coupling.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is part sectioned view of the present utility model.
Embodiment
As Fig. 1, provided a kind of universal coupling with spider shown in 2, comprise two jaws 1 and a cross axle 2, be provided with two coaxial through holes 11 on each jaw 1, four radial axles 21 on the described cross axle 2 respectively with the corresponding inserting one by one of four jaw through holes 11, the axial end portion of every radial axle 21 is provided with one and prevents its thrust device 3 in axial sliding on the described cross axle 2, described thrust device 3 comprises a pressing plate 31, one is with externally threaded nut 32 and a cover plate 33, and screw 34, described pressing plate 31 structure that takes the shape of the letter U, described U-shaped pressing plate 31 is set on the axial end portion of radial axle 21, the outer surface of U-shaped pressing plate 31 is provided with step, described nut 32 is set on the outer surface of U-shaped pressing plate 31, and step surface 311 butts of the interior edge face of nut 32 and U-shaped pressing plate 31, the exterior edge face of described jaw through hole 11 is provided with the groove 111 of ccontaining described nut 32, and the inwall of groove 111 be provided with nut 32 on the internal thread of outside thread bolt, described cover plate 33 press-fits on the exterior edge face of nut 32, and fixing by screw 34 between described cover plate 33 and the jaw 1.
Adopt said structure, because the utility model has been set up between described cross axle 2 and jaw through hole 11 and has been prevented its thrust device 3 in axial sliding, therefore in the coupling running, can prevent endwisely slipping or play of cross axle 2 effectively, thereby improved the reliability of coupling greatly, and then also just prolonged the working life of coupling.
