Description
Technical field
The utility model relates to auto parts machinery field, the durable transmission shaft that specifically a kind of structure simple seal is good.
Background technique
Transmission shaft is the vitals of transferring power in automotive transmission, its effect be together with gearbox, ransaxle by the transmission of power of motor to wheel, make automobile produce driving force.Transmission shaft structure is in the market more complicated, and difficulty of processing is large, and is in use easily subject to the erosion of sand and dust, affects the working life of transmission shaft.
Model utility content
The purpose of this utility model is the durable transmission shaft providing a kind of structure simple seal good, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
The durable transmission shaft that a kind of structure simple seal is good, comprise outer shroud, splined shaft and sleeve, described outer shroud is fixed on one end of splined shaft, the other end of splined shaft is provided with external splines, described external splines is involute splines, the internal spline matched with external splines is provided with in sleeve, external splines is engaged in internal spline, at least one-level multidiameter shaft is provided with between outer shroud and splined shaft, and away from the outermost multidiameter shaft of outer shroud as limited ring, limit splined shaft and insert the degree of depth in sleeve, sleeve is also provided with Sealing at the connecting end of itself and splined shaft; Described sleeve is provided with step-like fixed cover away from one end of splined shaft, is set with end cap in fixed cover, is provided with urethane rubber oil sealing between end cap and fixed cover, and fixed cover end stretches out and is formed with connecting base.
As further program of the utility model: described multidiameter shaft is two-stage altogether.
As the utility model further scheme: be provided with twice urethane rubber oil sealing between described end cap and fixed cover.
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, this transmission shaft external splines and internal spline all adopt involute splines, eliminate mill spline flank in the fabrication process, reduce manufacture difficulty, saved cost; 3, this transmission shaft sleeve is provided with Sealing at the connecting end of itself and splined shaft, enhance the sealing between splined shaft and sleeve, twice urethane rubber oil sealing is provided with in addition between end cap and fixed cover, the sealing of further enhancing splined shaft and sleeve, make extension shaft not by the erosion of extraneous sand and dust, not only dust-proof but also antirust, therefore in splined shaft with cover, disposable lubricating grease is smeared when assembling, just usage requirement can be met completely, do not need to fill fitting lubrication, decrease maintenance content time and expense.
Accompanying drawing explanation
Fig. 1 is the structural representation of the durable transmission shaft that structure simple seal is good.
In figure: 1-outer shroud, 2-multidiameter shaft, 3-splined shaft, 4-external splines, 5-Sealing, 6-sleeve, 7-fixed cover, 8-connecting base, 9-end cap.
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, the durable transmission shaft that a kind of structure simple seal is good, comprises outer shroud 1, splined shaft 3 and sleeve 6, described outer shroud 1 is fixed on one end of splined shaft 3, the other end of splined shaft 3 is provided with external splines 4, preferably, described external splines 4 is involute splines, the internal spline matched with external splines 4 is provided with in sleeve 6, external splines 4 is engaged in internal spline, at least one-level multidiameter shaft 2 is provided with between outer shroud 1 and splined shaft 3, preferably, described multidiameter shaft 2 is two-stage altogether, and away from the outermost multidiameter shaft 2 of outer shroud 1 as limited ring, restriction splined shaft 3 inserts the degree of depth in sleeve 6, sleeve 6 is also provided with Sealing 5 at the connecting end of itself and splined shaft 3, Sealing 5 strengthens the sealing between splined shaft 3 and sleeve 6, described sleeve 6 is provided with step-like fixed cover 7 away from one end of splined shaft 3, end cap 9 is set with in fixed cover 7, urethane rubber oil sealing is provided with between end cap 9 and fixed cover 7, preferably, be provided with twice urethane rubber oil sealing between described end cap 9 and fixed cover 7, fixed cover 7 end stretches out and is formed with connecting base 8.
The durable transmission shaft that described structure simple seal is good adopts outer shroud 1 that axle is more easily installed, multidiameter shaft 2 between outer shroud 1 and splined shaft 3 can strengthen the bulk strength of bearing greatly, increase the service life, external splines 4 and internal spline all adopt involute splines in addition, eliminate mill spline flank in the fabrication process, reduce manufacture difficulty, save cost.Sleeve 6 is also provided with Sealing 5 at the connecting end of itself and splined shaft 3, enhance the sealing between splined shaft 3 and sleeve 6, twice urethane rubber oil sealing is provided with in addition between end cap 9 and fixed cover 7, the sealing of further enhancing splined shaft 3 and sleeve 6, make extension shaft not by the erosion of extraneous sand and dust, not only dust-proof but also antirust.Therefore in splined shaft with cover, disposable smearing lubricating grease when assembling, just can meet usage requirement completely, do not need to fill fitting lubrication, decrease and maintain content time and expense.
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.
