Abstract
The present invention provides a kind of universal coupling with spider, bag spline housing, the splined shaft being engaged with the spline housing, the jaw being separately fixed on the right of the spline housing left side and splined shaft, the flange jaw for being hinged each via cross axle cooperation with the jaw respectively, it is characterised in that：The flange jaw includes half symmetrical flange jaw, described two half flange jaws wrap up cross axle, and both separate and are fixedly connected, the bearing hole bottom not insertion of the flange jaw and jaw, and bearing hole bottom is with setting spacing hole, with cross axle location fit, structure design of the present invention is reliable, in the case where not reducing flange jaw intensity, the bearing and cross axle of large-diameter can be loaded, so that the intensity of SWK type cross-axle universal shaft couplings is greatly improved, this structure also makes bearing hole end wall and bottom hole be linked to be firm entirety, greatly improve flange jaw bulk strength.Simultaneously because bearing capacity is significantly increased, also accordingly increase thereby using the life-span.
Description
Technical field
The present invention is directed applying to the joint transmission technology applying on the jumboes such as rolling mill, driving, more particularly to one
Plant universal coupling with spider.
Background technology
In decades, with the development more and more higher of heavy industry industry, for its related auxiliary facility be also increasingly by
To the attention of people.But be used as in the highly important shaft coupling of transmission field, significant progress is not obtained but.Make a general survey of the country
The research and development of outer universal coupling with spider and service condition, are broadly divided into the patterns such as SWC, SWP and SWZ.Today for connection
In the use requirement of axle device, this several Hooks coupling universal coupling is increasingly difficult in adapt to new demand.
And limitation of the flange jaw and cross axle of conventional universal drive shaft in assembling because of space, the diameter of cross axle
Can not be too big, flange jaw bearing hole length limited, transmission moment of torsion is limited.
Conventional universal drive shaft uses jump ring and back-up ring fixed cross axle and bearing mostly.But this structure is in transmission favourable opposition
Easily jump ring top is flown when hitting moment of torsion, causes bearing to come off, cross axle is scrapped.
The content of the invention
In order to overcome the technical deficiency of the above, the present invention provides a kind of Novel cross shaft formula Hooks coupling universal coupling, and its structure can
Lean on, transmission moment of torsion is big, the advantages of service life is long.
The present invention provides a kind of universal coupling with spider, bag spline housing, the splined shaft being engaged with the spline housing, divides
The jaw on the right of the spline housing left side and splined shaft is not fixed on, be hinged the method for cooperation with the jaw respectively each via cross axle
Blue jaw, the flange jaw includes half symmetrical flange jaw, and described two half flange jaws wrap up cross axle, and two
Person is separable to be fixedly connected, the bearing hole bottom not insertion of the flange jaw and jaw, and bearing hole bottom is limited with setting
Position hole, with cross axle location fit.
Annular wear set is installed between the spline housing and splined shaft.
The annular wear set is provided with baffle plate with spline housing, and the baffle plate is fixed by bolt with spline housing.
Half flange jaw is fixedly connected by taper pin.
Half flange jaw is fixedly connected by locating piece.
The cross axle is provided with the positioning hole being engaged with the spacing hole of bearing hole bottom.
The beneficial effect of invention is：Structure design of the present invention is reliable, in the case where not reducing flange jaw intensity, can be with
Load the bearing and cross axle of large-diameter, so that the intensity of SWK type cross-axle universal shaft couplings is greatly improved（Static strength ratio
SWC series improves more than 50%）, this structure also makes bearing hole end wall and bottom hole be linked to be firm entirety, makes flange jaw overall
Intensity is greatly improved.Simultaneously because bearing capacity is significantly increased, also accordingly increase thereby using the life-span.
Brief description of the drawings
Fig. 1 is the floor map of the present invention.
Fig. 2 is enlarged diagram at C in Fig. 1.
Fig. 3 is Fig. 1 A-A cross section views.
Fig. 4 is Fig. 1 B direction views.
Embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention provides a kind of universal coupling with spider, and it is SWK type crosses
Axle Hooks coupling universal coupling, its bag spline housing 3, the splined shaft 4 being engaged with the spline housing 3, is separately fixed at the left side of spline housing 3 and flower
The jaw 2 on the right of key axle 4（As shown in figure 1, upper is a left side, it is lower for the right side）, be hinged respectively with the jaw 2 each via cross axle 7
The flange jaw 1 of cooperation, the flange jaw 1 includes half symmetrical flange jaw 10, described two half flange jaws 10
Cross axle 7 is wrapped up, and both separate and are fixedly connected, the bearing hole bottom not insertion of the flange jaw 1 and jaw 2, and
Bearing hole bottom is with setting spacing hole 11, and with the location fit of cross axle 7, the cross axle 7 is provided with the limit with bearing hole bottom
The positioning hole that position hole 11 is engaged.
Half flange jaw 10 is fixedly connected by taper pin 8.The taper pin 8 is separately fixed at the upper of half flange jaw 10
Lower two ends, play a part of fixing both.
Half flange jaw 10 is fixedly connected by locating piece 9, and the locating piece 9 is horizontally placed on determining for half flange jaw 10
In the groove of position, certain positioning action is played when merging to both.
Flange jaw 1 is divided into two symmetrical two and half flange jaws 10, it is solid with locating piece and taper pin again in assembling
It is scheduled on together, cross axle and bearing can make full use of space, SWK types cross-axle universal shaft coupling is transmitted moment of torsion and greatly increase
Plus.Bearing capacity is significantly increased simultaneously, is also accordingly increased thereby using the life-span.
Spacing hole 11 is set in bearing hole bottom, on the premise of the globality of bearing hole bottom is ensured, using less
The positioning hole of spacing hole and cross axle carries out spacing cooperation, and the structure can make bearing hole end wall and bottom hole be linked to be firm
It is overall, flange jaw bulk strength is greatly improved, while be also avoided that in the past by the way of jump ring and back-up ring are fixed, may
Cause easily to fly jump ring top when transmitting large impact moment of torsion, the phenomenon for causing bearing to come off, to cross axle and bearing positioning accurate
Standard, structure is firm, substantially reduces the probability for accident occur.
Annular wear set 5 is installed between the spline housing 3 and splined shaft 4.Due to pacifying between spline housing 3 and splined shaft 4
Equipped with annular wear set 5 so that shaft coupling weares and teares reduction in transmission, transmission stability and precision are improved, service life
Extended.
The annular wear set 5 is provided with baffle plate 6 with spline housing 3, and the baffle plate 6 is fixed with spline housing 3 by bolt, adopted
With the mode that the activity of baffle plate 6 is fixed, annular wear set 5 is movably fixed on spline housing 3, easily with being fixed by way of changing
Annular wear set 5, is changed to it, greatly extends the service life of shaft coupling, is conducive to improving production efficiency.
Embodiment is not construed as limitation of the present invention, but any spiritual improvements introduced based on the present invention, all should be
Within protection scope of the present invention.
