Abstract
The utility model discloses a universal joint type universal coupling which comprises two fork heads and a universal joint. Each fork head is provided with two coaxial through holes, four radial shafts on the universal joint are inserted into four fork head through holes in corresponding mode respectively, and the axial end of each radial shaft on the universal joint is provided with a pushing resisting device preventing the radial shaft from sliding axially. Each pushing resisting device comprises a pressing plate which is of a U-shaped structure, and the U-shaped pressing plate is sleeved on the axial end of each radial shaft and fixedly connected with each fork head through hole. By means of the structure, the pushing resisting devices preventing the radial shafts from sliding axially are arranged among the universal joint and the fork head through holes, in an operation process of the coupling, axial sliding or moving of the universal joint can be avoided effectively, the reliability of the coupling is greatly improved, and the service life of the coupling is 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 a pressing plate, 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, and U-shaped pressing plate and described jaw through hole are affixed.
The outer surface that the utility model can further be set to described U-shaped pressing plate is provided with step, is pressed with an annular cover on the step surface of described U-shaped pressing plate, and described annular cover is installed on the jaw by screw.
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, 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, be pressed with an annular cover 32 on the step surface 311 of described U-shaped pressing plate 31, described annular cover 32 is installed on the jaw 1 by screw 33.
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.
