Description
Technical field
The utility model relates to auto parts machinery field, specifically a kind of simple and practical transmission shaft.
Background technique
Transmission shaft is the solid of rotation of a high rotating speed, few supporting, and therefore its dynamic balancing is vital.General transmission shaft all will carry out dynamic balance running before dispatching from the factory, and adjusts on balancing machine.The material of axle mainly adopts carbon steel or alloyed steel, also can adopt spheroidal graphite cast iron or alloy cast iron etc.The ability to work of axle generally depends on strength and stiffness, also depends on stability of vibration during rotating speed height.Transmission shaft structure is in the market comparatively complicated, and easily weares and teares in using process.
Model utility content
The purpose of this utility model is to provide a kind of simple and practical transmission shaft, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A simple and practical transmission shaft, comprises outer shroud, splined shaft and central shaft; Described outer shroud is fixed on one end of splined shaft, and the other end of splined shaft connects central shaft, and this one end that splined shaft connects central shaft is provided with external splines, and described external splines is involute splines, and external splines surface is provided with protective layer; Be provided with at least one-level multidiameter shaft between described outer shroud and splined shaft, and near the multidiameter shaft of splined shaft as limited ring, inside limited ring, be also provided with Sealing; Described central shaft is provided with arc-shaped slot, and arc-shaped slot is multiple altogether, and centrally the axis centre of axle is symmetrical.
As further program of the utility model: described protective layer is zinc-plated protective layer.
As the utility model further scheme: described multidiameter shaft is two-stage altogether.
As the utility model further scheme: the quantity of described arc-shaped slot is 4.
Compared with prior art, the beneficial effects of the utility model are: 1, this transmission shaft adopts outer shroud that axle is more easily installed, and the multidiameter shaft between outer shroud and splined shaft can strengthen the bulk strength of bearing greatly, and bulk strength is high, long service life; 2, the external splines of this transmission shaft is involute splines, and eliminate mill spline flank in the fabrication process, reduce manufacture difficulty, saved cost, external splines surface is provided with protective layer, and protective layer can working life of elongate member, reduces external splines wearing and tearing; 3, the central shaft notch of this transmission shaft is arc-shaped, makes transmission shaft in the concrete process used, has expanded the surface of contact between groove and key, and balanced moment suffered by it, reduces the wearing and tearing of notch, extend the working life of notch further.
Accompanying drawing explanation
Fig. 1 is the structural representation of simple and practical transmission shaft.
In figure: 1-outer shroud, 2-multidiameter shaft, 3-Sealing, 4-splined shaft, 5-external splines, 6-central shaft, 7-arc-shaped slot.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of simple and practical transmission shaft, comprises outer shroud 1, splined shaft 4 and central shaft 6; Described outer shroud 1 is fixed on one end of splined shaft 4, and the other end of splined shaft 4 connects central shaft 6, and this one end that splined shaft 4 connects central shaft 6 is provided with external splines 5, preferably, described external splines 5 is involute splines, and external splines 5 surface is provided with protective layer, preferably, described protective layer is zinc-plated protective layer, protective layer can working life of elongate member, reduces expenditure, original rectangular spline is improved to involute splines, eliminate mill spline flank in the fabrication process, reduce manufacture difficulty; At least one-level multidiameter shaft 2 is provided with between described outer shroud 1 and splined shaft 4, preferably, described multidiameter shaft 2 altogether two-stage, and near the multidiameter shaft 2 of splined shaft 4 as limited ring, also be provided with Sealing 3 inside limited ring, Sealing 3 is for strengthening sealing when splined shaft 4 connects with corresponding axle sleeve; Described central shaft 6 is provided with arc-shaped slot 7, and arc-shaped slot 7 is multiple altogether, and centrally the axis centre of axle 6 is symmetrical, preferably, the quantity of arc-shaped slot 7 is 4, and notch shape is arranged to arc-shaped, makes transmission shaft in the concrete process used, expand the surface of contact between groove and key, the moment of further equilibrium suffered by it, reduces the wearing and tearing of notch, extends the working life of notch, be provided with multiple groove, the moment of having shared required transmission extends the working life of notch further.
Described simple and practical transmission shaft adopts outer shroud that axle is more easily installed, and the multidiameter shaft between outer shroud and splined shaft can strengthen the bulk strength of bearing greatly, and bulk strength is high, long service life; The external splines of described simple and practical transmission shaft is involute splines, eliminates mill spline flank in the fabrication process, reduces manufacture difficulty, save cost, external splines surface is provided with protective layer, and protective layer can working life of elongate member, reduces external splines wearing and tearing; The central shaft notch of described simple and practical transmission shaft is arc-shaped, makes transmission shaft in the concrete process used, has expanded the surface of contact between groove and key, and balanced moment suffered by it, reduces the wearing and tearing of notch, extend the working life of notch further.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
