The good spline of heart stability, including spline outer barrel and the splined shaft through spline outer barrel, outer end of splined shaft are provided with several
Rectangular block is connected with inclined-plane between rectangular block, and spline outer barrel inner face offers several grooves, and spline outer barrel outer end face surrounds
There are ball, one end of seat between being covered on ball, seat to be connected with outer ring, the other end of seat is connected with flange outer ring.
As a kind of optimal technical scheme of the utility model, the angle of the tangent plane of cambered surface between inclined-plane and rectangular block
It between 5 ° to 30 °, is easily worked, and effectively reduce processing cost, and convenient for corresponding with transmission direction, turns to increase
The cooperation depth in dynamic direction, accordingly reduces the cooperation depth in nonrotational direction.
As a kind of optimal technical scheme of the utility model, corresponding engaging between groove and rectangular block, and groove and square
Shape block contact surface is coated with steel membrane, realizes this good technology of the centering stability of the utility model, and the coating of steel membrane is real
The wearability of existing rotating surface, extends the utility model service life.
As a kind of optimal technical scheme of the utility model, spline outer barrel both ends periphery is both provided with ball, and ball
Between connected by retainer, convenient for the utility model and external device (ED) collective effect, and the firm of the utility model can be kept
Property.
As a kind of optimal technical scheme of the utility model, the contact site attachment between flange outer ring and spline outer barrel
There is gasket, realizes the stability connection of the utility model.
The advantageous effect that the utility model is reached is：The utility model is a kind of spline that centering stability is good, is passed through
Close between the rectangular block of setting and groove engages, and can realize high centering stability, and traditional spline is compared, this practicality
Slot bottom between novel flower rectangular block is that plane enables to spend by the way that the slot bottom on splined shaft is changed to plane by cambered surface
The slot bottom of key axis is easily worked, and effectively reduces processing cost, is arranged on spline outer barrel inner face furthermore it is possible to effectively reduce
Groove stress (contact area is bigger, and stress is with regard to smaller), can increase the service life of the utility model, reduce failure.
