Abstract
The utility model relates to a spline pair for a cross axle type universal coupling. The utility model comprises a spline shaft (5) and a spline housing (2). The inside wall of the spline housing (2) is provided with a recess (7), or a centring shaft sleeve (3) is arranged at the back of the recess (7). The middle part is a splined hole and namely is an internal spline (6), and the other end is tightly fixed by a holding screw (4) after a centring shaft sleeve (3) is placed. An interspace of an oil injecting hole and the recess (7) totally can store lubricating oil, and a welding position (9) is welded with a fork head (1). In this way, the utility model can quite conveniently produce a large specification of exceptional length extension shaft coupling.
Description
The utility model belongs to the coupling field, refers in particular to the universal coupling with spider spline pair.
As everyone knows, universal coupling with spider (hereinafter to be referred as coupling) engages with spline pair and compensates its axial stretching now, spline pair is made of splined shaft and spline housing, splined shaft is external splines, it is internal spline that the spline housing inwall has splined hole, and internal spline not only plays the function of transmitting torque but also plays centering.On general, to the requirement of spline pair be: (in the formula: L is that splined shaft centering length is bonding length, and D is the diameter of spline pair in L/D=1.5～2.5; Get 2.5 times at present abroad, the standard-required of China is 2 times).This is to consider that long axle will lean on long spline pair to engage and guarantee its stability and reliability.But for the coupling of big specification, MANUFACTURER will guarantee L/D=1.5～2.5, just seems powerless, because the splined shaft bonding length is oversize, involute inner spline especially can be described as and can't process internal spline.Because the increase of difficulty of processing, the cost of coupling of making big specification is very big.Yet along with expanding economy, the demand of the coupling of big specification is increasing.The coupling that the big specification of high quality and low cost is provided is that people ask.
The purpose of this utility model is to overcome the defective that exists in the above-mentioned prior art, and a kind of spline pair of ten shaft type Hooks coupling universal couplings is provided, and just can quite easily make the coupling of big specification with the spline pair of this structure.
For achieving the above object, the solution that the utility model is taked is: a kind of universal coupling with spider spline pair, comprise splined shaft and spline housing, a tool withdrawal groove is arranged in the spline housing inwall or behind tool withdrawal groove, place a centration axis cover, middle for splined hole be that internal spline, the other end are placed a centration axis cover again.
In the utility model, centering relies on the centering axle sleeve, and internal spline only plays the function of transmitting torque, that is to say that internal spline is born centering function and transmitting torque functional separation separately in the prior art.Therefore, under the situation of stable required splined shaft centering length L=(1.5～2.5) D that guarantees coupling, the length L 1[that can shorten internal spline fully considers that from intensity L1=(0.6～1) D gets final product], facilitate like this and produced, manufacture cost descends widely.Because utilize the centering of centering axle sleeve, the centering axle sleeve can improve coaxial precision; Owing to the not responsible centering of internal spline, its machining accuracy also can reduce again; And all can store lubricant oil at the gap and the tool withdrawal groove place that strengthen, reduce contact, increase lubricated, thereby the power of reducing friction makes spline pair capable of expansion and contraction, has improved working life.Utilize the spline pair of this kind structure, can satisfy any requirement of user, promptly can L/D 〉=2.5, can make the flexible coupling of overlength with comparalive ease.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Fig. 1 is present embodiment structural representation in coupling.
Fig. 2 is the spline pair structural representation in the prior art coupling.
As shown in Figure 1, a kind of universal coupling with spider spline pair, comprise splined shaft (5) and spline housing (2), a tool withdrawal groove (7), middle for splined hole is internal spline (6), the other end is placed Cock screw (4) tightening of a centration axis cover (3) back is again arranged in the inwall of spline housing (2); Also can place a centration axis cover (3) in tool withdrawal groove (7) back, their effect is the identical centering function that promptly has; It is lubricated to carry out oil storage by the gap of oil hole (8) between tool withdrawal groove (7) and internal spline (6) and splined shaft (5).On centering axle sleeve (3) internal circle, have oil storage tank.Increase lubricated face, reduced the wearing and tearing of spline pair, improved working life.Present embodiment is by weld (9) and jaw (1) welding.In another case, spline housing (2) can be an integral body with jaw (1).
Fig. 1 and Fig. 2 are done a contrast, can be clearer: both met L/D=1.5～2.5, and guaranteed centering function to the beneficial effect that the utility model produces; Under the prerequisite that guarantees the transmitting torque function, reduce the difficulty [L1=(0.6～1) D] of processing internal spline (6) again widely; Become a reality thereby make to users provide the flexible coupling of big specification overlength of high quality and low cost.
Claims (3)
1, a kind of universal coupling with spider spline pair, comprise splined shaft (5) and spline housing (2), it is characterized in that: a tool withdrawal groove (7) is arranged in the inwall of spline housing (2) or place a centration axis cover (3), centre for splined hole is internal spline (6), the other end is placed a centration axis cover (3) again in tool withdrawal groove (7) back.
2, a kind of universal coupling with spider spline pair according to claim 1 is characterized in that: it is lubricated to carry out oil storage by the gap of oil hole (8) between tool withdrawal groove (7) and internal spline (6) and splined shaft (5).
3, a kind of universal coupling with spider spline pair according to claim 1 is characterized in that: have oil storage tank on centering axle sleeve (3) internal circle.
