Abstract
A kind of shaped bead, including the first axle sleeve, the second axle sleeve, fixed pedestal, rounding off connects between first axle sleeve and the second axle sleeve, rounding off connects between second axle sleeve and fixed pedestal, first axle sleeve, the second axle sleeve and fixed pedestal form a sealed cylinder for being provided with centre bore, the centre bore is by a sloping step hole and internal tooth wheel bore forms always, " X " type end side tooth is provided with the interface of described fixed pedestal, and fixed pedestal is split into base portion and obtuse angle base portion at an acute angle, described obtuse angle base portion caves inward.It is more reasonable to be connected between the axle sleeve of the utility model first, the second axle sleeve, fixed pedestal, flange is safer in actual use, seal washer will not be scratched, extend service life, on the other hand while can guarantee that enough intensity, save and use material, reduce production cost, realize light-weight design.
Description
Technical field
Technical field of automobile parts is the utility model is related to, particularly belongs to a kind of shaped bead.
Background technology
Flange is the part of power transmission shaft upper process, can play a part of local vibration damping and transmission.
In the prior art, the position of bridge, power caused by engine drive drive axis, pass through power transmission shaft in the car
By on the gear of power transmission to decelerator, power transmission shaft drives flange to rotate by the end face bolt connection with flange, power transmission shaft
Through the axle sleeve of flange, bridge case is reconnected, seal washer is provided between bridge case and flange axle sleeve, bridge case is sealed
Getting up prevents the gear oil in bridge case from spilling.And the end face and the outer wall angle of flange that flange contacts with bridge case are right angle,
I.e. the end face is mutually perpendicular to flange outer circumference surface.So, when the driven axle of flange drives rotation, described end face with it is convex
The right-angle structure formed between edge outer wall is relatively sharp, can scratch seal washer, causes the gear oil in bridge case to leak.
On the other hand, because flange of end face tooth with the stability of its passing power obtains more and more extensive use, but with
The increasing of flange of end face tooth dosage, Cost Problems and weight issue just highlight, and how to ensure flange of end face tooth
Its weight is reduced on the premise of energy, reduces the cost of flange of end face tooth, turns into and improves the outlet that product competitiveness seizes market.
Utility model content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to provide a kind of shaped bead, a side
Face extends the service life of seal washer, is not in leakage, and it is more, again on the other hand to solve current flange of end face tooth materials
The problem of amount is big, cost is high.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of shaped bead, including the first axle sleeve, the second axle sleeve, fixed pedestal, first axle sleeve and the second axle sleeve it
Between circle
Slip over and cross connection, between the second axle sleeve and fixed pedestal rounding off connect, first axle sleeve, the second axle sleeve with
And fixed pedestal forms a sealed cylinder for being provided with centre bore, the centre bore is by a sloping step hole and internal gear always
Hole forms, and is provided with " X " type end side tooth on the interface of described fixed pedestal, and by fixed pedestal split base portion at an acute angle and
Obtuse angle base portion, described obtuse angle base portion cave inward.
As preferable technical scheme, spline tooth, the angle of engagement of described spline tooth are provided with the straight internal tooth wheel bore
For
37.5°。
As preferable technical scheme, the angle of the vertical direction of second axle sleeve and fixed pedestal is 104 °.
Compared to prior art, advantageous effects of the present utility model are：
1st, connected between the axle sleeve of this practicality first, the second axle sleeve, fixed pedestal more rationally, flange actual use when more
Add safety, seal washer will not be scratched, extend service life.
2nd, the obtuse angle base portion of this practical fixed pedestal caves inward, and while can guarantee that enough intensity, saves with material,
Production cost is reduced, realizes light-weight design.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 left view；
Fig. 3 is Fig. 1 right view；
Label is schematically as follows in figure：The axle sleeves of 1- first, the axle sleeves of 2- second, 3- fixed pedestals, 4- bolts hole, 5- sloping steps
Hole,
The straight internal gears of 6-, 7- end-tooths, 8- spline tooths, 9- acute angles base portion, 10- obtuse angles base portion.
Embodiment
A kind of shaped bead described in the utility model is elaborated with reference to specific embodiment：
Such as Fig. 1, a kind of shaped bead, including the first axle sleeve 1, the second axle sleeve 2, fixed pedestal 3, first axle sleeve 1 with
Between second axle sleeve 2 rounding off connect, between the second axle sleeve 2 and fixed pedestal 3 rounding off connect, second axle sleeve with
The angle of the vertical direction of fixed pedestal is 104 °, ensures that flange in actual use, will not scratch seal washer, during use
It is safer, so as to extend service life.
First axle sleeve 1, the second axle sleeve 2 and fixed pedestal 3 form a sealed cylinder for being provided with centre bore, institute
Centre bore is stated by a sloping step hole 5 and internal tooth wheel bore 6 forms always, is provided with " X " on the interface of described fixed pedestal 3
Type end side tooth 7, and fixed pedestal 3 is split into base portion 9 and obtuse angle base portion 10 at an acute angle, described obtuse angle base portion 10 caves inward,
Both enough intensity had been can guarantee that, while the change of end surface shape is saved with material, is reduced production cost, is realized lightweight and set
Meter, is easy to enterprise competitiveness.
As preferable technical scheme, spline tooth, the angle of engagement of described spline tooth are provided with the straight internal tooth wheel bore
For
37.5 °, the number of teeth 49.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvement can also be made, these improvement also should be regarded as
The scope of protection of the utility model.
