Abstract
The invention provides a cross-shaft type universal coupling. The cross-shaft type universal coupling comprises a spline housing, a spline shaft, a fork and a flange fork. The fork is fixed on the left side of the spline housing and right side of the spline shaft, and the flange fork matched with the fork in a hinged manner through across shaft. The cross-shaft type universal coupling is characterized in that the flange fork comprises two half flange fork bodies which are symmetrically distributed, the half flange fork bodies wrap the cross shaft and can be detachably and fixedly connected, the bottom of a bearing hole of the flange fork and the fork is not communicated, and a limit hole arranged in the bottom of the bearing hole is in positioning fit with the cross shaft. The cross-shaft type universal coupling is reliable in structural design, the bearing and the cross shaft large in shaft diameter can be mounted in the universal coupling, strength of the SWK-type cross-shaft universal coupling can be greatly improved, the end wall of the bearing hole and the bottom of the hole can be firmly connected into a whole, and integral strength of the flange fork is greatly improved; meanwhile, capacity of the bearing is obviously increased, and service life of the universal coupling is correspondingly prolonged.
Description
Technical field
The present invention is directed apply to the joint transmission technology on the jumbo such as rolling mill, driving, particularly a kind of universal coupling with spider.
Background technique
In decades, along with the development of heavy industry industry is more and more higher, the auxiliary facility relevant for it is also more and more be subject to people's attention.But as at the very important coupling of transmission field, but do not obtain significant progress.Make a general survey of research and development and the service condition of domestic and international universal coupling with spider, be mainly divided into the patterns such as SWC, SWP and SWZ.Current in the usage requirement of coupling, this several Hooks coupling universal coupling is more and more difficult to adapt to new demand.
And the flange jaw of cardan shaft in the past and cross axle when assembling because the restriction in space, the diameter of cross axle can not be too large, and flanged yoke head bearing hole length is limited, and transmitting torque is limited.
Cardan shaft in the past uses jump ring and back-up ring fixed cross axle and bearing mostly.But this structure easily flies jump ring top when transmitting large impact moment of torsion, and cause bearing to come off, cross axle is scrapped.
Summary of the invention
In order to overcome above technical deficiency, the invention provides a kind of Novel cross shaft formula Hooks coupling universal coupling, its structure is reliable, and transmitting torque is large, the advantages such as long service life.
The invention provides a kind of universal coupling with spider, bag spline housing, the splined shaft matched with this spline housing, be separately fixed at jaw on the right of the spline housing left side and splined shaft, each via the cross axle flange jaw that coordinate hinged with described jaw respectively, described flange jaw comprises half symmetrical flange jaw, described two and half flange jaw parcel cross axles, and both are separable is fixedly connected with, not through bottom the bearing hole of described flange jaw and jaw, and bottom bearing hole with spacing hole is set, with cross axle location fit.
Annular wear cover is installed between described spline housing and splined shaft.
Described annular wear cover is provided with baffle plate with spline housing, and described baffle plate is fixed by bolt and spline housing.
Described half flange jaw is fixedly connected with by taper pin.
Described half flange jaw is fixedly connected with by positioning block.
Described cross axle is provided with the positioning hole matched with the spacing hole bottom bearing hole.
The beneficial effect of the invention is: structural design of the present invention is reliable, when not reducing flange jaw intensity, bearing and the cross axle of large-diameter can be loaded, thus the intensity of SWK type cross-axle universal shaft coupling is improved (static strength raising more than 50% more serial than SWC) greatly, this structure also makes to be linked to be firm entirety at the bottom of bearing hole end wall and hole, and flange jaw bulk strength is greatly improved.Simultaneously because bearing capacity enlarges markedly, thus also corresponding increase in working life.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the invention provides a kind of universal coupling with spider, it is SWK type cross-axle universal shaft coupling, its bag spline housing 3, the splined shaft 4 matched with this spline housing 3, be separately fixed at jaw 2(on the right of spline housing 3 left side and splined shaft 4 as shown in Figure 1, upper for left, lower to right), each via the cross axle 7 flange jaw 1 that coordinate hinged with described jaw 2 respectively, described flange jaw 1 comprises half symmetrical flange jaw 10, described two and half flange jaws 10 wrap up cross axle 7, and both are separable is fixedly connected with, not through bottom the bearing hole of described flange jaw 1 and jaw 2, and bottom bearing hole with spacing hole 11 is set, with cross axle 7 location fit, described cross axle 7 is provided with the positioning hole matched with the spacing hole 11 bottom bearing hole.
Described half flange jaw 10 is fixedly connected with by taper pin 8.Described taper pin 8 is separately fixed at the two ends up and down of half flange jaw 10, plays the effect both fixed.
Described half flange jaw 10 is fixedly connected with by positioning block 9, and described positioning block 9 is horizontally placed in the locating slot of half flange jaw 10, plays certain positioning action when merging both.
Flange jaw 1 is divided into two symmetrical two and half flange jaws 10, be fixed together with positioning block and taper pin when assembling, cross axle and bearing can make full use of space, and SWK type cross-axle universal shaft coupling transmitting torque is greatly increased again.Bearing capacity enlarges markedly simultaneously, thus also corresponding increase in working life.
Spacing hole 11 is set bottom bearing hole, under the prerequisite ensureing the integrity bottom bearing hole, less spacing hole is utilized to carry out spacing cooperation with the positioning hole of cross axle, and this structure can make to be linked to be firm entirety at the bottom of bearing hole end wall and hole, flange jaw bulk strength is greatly improved, also can avoid the mode in the past adopting jump ring and back-up ring to fix simultaneously, may cause and easily jump ring top be flown when transmitting large impact moment of torsion, cause the phenomenon that bearing comes off, to cross axle and bearing accurate positioning, structure is firm, greatly reduces the probability occurring accident.
Between described spline housing 3 and splined shaft 4, annular wear is installed and overlaps 5.Overlap 5 owing to being provided with annular wear between spline housing 3 and splined shaft 4, coupling is worn and torn reduction in transmission, and transmission stability and precision are improved, and working life is extended.
Described annular wear cover 5 is provided with baffle plate 6 with spline housing 3, described baffle plate 6 is fixed by bolt and spline housing 3, adopt the mode that baffle plate 6 activity is fixing, annular wear cover 5 is movably fixed on spline housing 3, by very easily with the mode stationary ring wear-resistant sleeve 5 changed, it is changed, extends the working life of coupling greatly, be conducive to enhancing productivity.
Embodiment should not be considered as limitation of the present invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
