Abstract
The utility model discloses a non -maintaining type cross axle universal joint has a body and four bearing cup, the axle body has four axle head portions that are the cross and distribute, and four bearing cup one -to -one covers are established in four axle head portions, be equipped with nylon coating on the periphery of axle head portion and/or person bearing cup's the interior circumference wall, the terminal surface of axle head portion is equipped with the nylon pad with bearing cup's inner bottom interfacial. This novel non -maintaining type cross axle universal joint adopts to scribble on the periphery of axle body and/or person bearing cup's interior circumference wall and establishes nylon coating, and the structure is extremely succinct, and the equipment is simple compact, with the help of nylon coating from lubrication action, can guarantee that the bearing of cross axle can keep having the greasy property for a long time, lubricated effect is good, increase of service life, the user need not regularly to carry on the loaded down with trivial details maintenance operation of maintenance moreover, but greatly reduced manufacturing cost. And originally traditional structure is compared to novel cross axle universal joint, still can strengthen the structural strength of cross axle universal joint.
Description
Technical field
The utility model relates to Hooke's joint assembly, specifically refers to a kind of non-maintaining type Hooke's joint.
Background technique
Cross shaft rigid universal joint is widely used nonconstant velocity universal joint on automobile, and it is mainly made up of a cross axis body, four needle bearing bowls, two universal-joint forks, and the hole on two universal-joint forks is enclosed within the two relative diameters of axle of cross axle respectively.When this rotates when driving shaft, driven shaft both can rotate thereupon, can swing in any direction again around spider center.
Tradition Hooke's joint structure, between its shaft end and needle bearing bowl, structure is comparatively complicated, there is larger space between the two, so easily causes connection loosing and affect overall construction intensity.And current cross axle structure, regularly play lubricant oil carries out maintaining to needs, due to friction and the not good problem of lubrication, easily the needle bearing bowl of universal joint assembly and cross axle and even universal-joint fork are caused damage, affect the performance of whole universal joint, also reduction of service life, regularly must carry out maintaining or replacing in this client.
Model utility content
The purpose of this utility model is to provide a kind of simple for structure compact and have the non-maintaining type Hooke's joint of the excellent non-maintaining function of selflubricating, greatly improves usability and the life-span of cross axle.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of non-maintaining type Hooke's joint, has axle body and four cups; Axle body has four shaft ends in cross distribution, and four cup one_to_one corresponding are set on four shaft ends; The circumferential surface of shaft end and/or the inner peripheral wall of cup are provided with nylon coating, are provided with nylon pad between the end face of shaft end and the inner bottom surface of cup.
The inner bottom surface of described cup is arranged with embedding groove, and nylon pad is embedded on embedding groove.
Described shaft end has circumferential surface, end face, and a transition connects the arc surface of this circumferential surface and end face; Cup correspondence has inner peripheral wall, bottom surface, and a transition connects the arc surface of this inner peripheral wall and bottom surface.
Also seal ring is provided with between the rim of a bowl of described cup and shaft end.
Described cup is also provided with the protecting cover that the two halves that arranged by phase make-up are formed.
Described axle body adopts carbon structure steel to be made.
After adopting such scheme, this novel maintenance-free type Hooke's joint, abandoning tradition adopts needle-type labyrinth, but employing is coated with nylon coating on the circumferential surface of axle body and/or the inner peripheral wall of cup, nylon pad is provided with between the end face of shaft end and the inner bottom surface of cup, structure is extremely succinct, assemble simply compact, by the self-lubricating function that nylon coating and nylon pad play separately, can ensure that the bearing of cross axle can keep having greasy property for a long time, lubrication effect is good, be not subject to friction damage, increase the service life, and user is without the need to regularly carrying out loaded down with trivial details maintaining operation, greatly can reduce cost of production.And this Novel cross-shaped shaft universal joint compares conventional construction, the diameter of axle of the shaft end of axle body can increase slightly relatively, also can strengthen the structural strength of Hooke's joint in this.
Accompanying drawing explanation
Fig. 1 is the structural representation of this novel maintenance-free type cross axle.
Label declaration
Axle body 1 shaft end 11
Circumferential surface 111 cup 2
Embedding groove 21 circumferential surface 22
Nylon coating 3 nylon pad 4
Seal ring 5.
Embodiment
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to a kind of non-maintaining type Hooke's joint, as shown in Figure 1, has axle body 1 and four cups 2.Axle body 1 preferably adopts carbon structure steel to be made, and four shaft ends, 11, four cup 2 one_to_one corresponding that this axle body 1 has in cross distribution are set on four shaft ends 11.
This novel main innovate point is, is provided with nylon coating 3, is provided with nylon pad 4 between the end face of shaft end 11 and the inner bottom surface of cup 2 in the circumferential surface of shaft end 11 and/or the inner peripheral wall of cup 2.Provide in preferred embodiment, nylon coating 3 paintings are located on the circumferential surface of shaft end 11; In addition, when nylon coating 3 be coated with simultaneously be located on the circumferential surface of shaft end 11 and the inner peripheral wall of cup 2 time, the thickness of the nylon coating on its circumferential surface of shaft end 11 is preferably greater than the thickness of the nylon coating on its inner peripheral wall of cup 2, guaranteeing under stabilized structure prerequisite in this, the selflubricating maintenance effect that nylon plays can promoted.Further, the better set-up mode of the one of nylon pad 4 is the inner bottom surface of cup 2 is arranged with embedding groove 21, nylon pad 4 is embedded on embedding groove 21, guarantees that nylon pad 4 is arranged and structure stability in using, to give full play to its self-lubricating effect with this.
Preferably, shaft end 11 has circumferential surface, end face, and a transition connects the arc surface 111 of this circumferential surface and end face, and in like manner, cup 2 correspondence has inner peripheral wall, bottom surface, and a transition connects the arc surface 22 of this inner peripheral wall and bottom surface.The arc surface structure that this transition connects, cuts the rubbing action between doff end 11 and cup 2 first, second also can be formed with space between inside and outside circle cambered surface, can be used as shoe cream room or as dirt receiving cavity.
Preferably, seal ring 5 is also provided with between the rim of a bowl of cup 2 and shaft end 11.Specifically, the afterbody of shaft end 11 is formed with the oblique section toward the necking down of direction, termination, and the inner side of seal ring 5 is formed with the suitable oblique ring of oblique section with this, in this by the phase interworking of oblique section with oblique ring, makes seal ring 5 have excellence firmly sealing protection performance again.
Preferably, cup 2 is also provided with protecting cover that the two halves that arranged by phase make-up form (not shown in the figures anticipate out), with this, protective action is carried out to its mainly exposed cup 2 part of cross axle structure.
The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
