Abstract
The utility model discloses a high-accuracy transmission shaft for a tractor. The high-accuracy transmission shaft comprises a shaft body and is characterized in that convex teeth arranged along the axial direction are distributed on the peripheral surface of the shaft body; a key-groove structure is formed between the adjacent convex teeth. Compared with the prior art, the high-accuracy transmission shaft disclosed by the utility model has the advantages that since the convex teeth and the key grooves are formed on the peripheral surface of a common transmission shaft, the transmission shaft can be matched with a shaft sleeve by the structure with the convex teeth and the key grooves in installation, so that fast positioning and installation of the shaft are realized, the positioning of the transmission shaft in assembly is more accurate and firmer, circumferential rotation of the transmission shaft after installation can be prevented, and further more reliable transferring of the transmission shaft is ensured and the operation is easier.
Description
Technical field
The utility model relates to transmission shaft, particularly a kind of highi degree of accuracy transmission shaft for tractor.
Background technique
Common tractor transmission shaft is all polished rod structure, transmission shaft directly inserts in axle sleeve, in order to prevent that axle from rotating, transmission shaft is the multidiameter shaft structure of multi-section type, and the barrier structure of dependence ladder surface is realized the axially locating of transmission shaft, still, this transmission shaft structure cannot accurately be located when mounted, after being assembled on bearing, easily occur to slide and skew, cause while installing and need multiple bearing to find accurately, reduce efficiency of assembling.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of highi degree of accuracy transmission shaft for tractor simple in structure and convenient for assembly for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of highi degree of accuracy transmission shaft for tractor, include axle body, it is characterized in that: on the outer circumferential face of described axle body, be distributed with the double wedge arranging vertically, between adjacent described double wedge, form keyway arrangements.
As preferably, described axle body includes the multidiameter shaft at main shaft and moulding and these main shaft two ends, and described double wedge is arranged at respectively on the end and described main shaft of described multidiameter shaft.
As further preferred, described double wedge is along the uniform setting of outer circumferential face of described axle body.
As preferably, between described double wedge and described axle body, be formed in one.
Compared with prior art, the utility model has the advantage of: on common transmission shaft outer circumferential face, form double wedge and keyway, make transmission shaft when mounted, can coordinate with axle sleeve by double wedge keyway arrangements, realize the quick location and installation of axle, make transmission shaft location when assembling more accurately firmly, prevent that transmission shaft from circumferential rotation occurring after installation, thereby the transmission of assurance transmission shaft is reliability more, handles lighter.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's transmission shaft side view.
Fig. 2 is that the A-A shown in Fig. 1 is to sectional view.
Fig. 3 is that the B-B shown in Fig. 1 is to sectional view.
Fig. 4 is that the C-C shown in Fig. 1 is to sectional view.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1 to 4, the transmission shaft of the present embodiment is a kind of highi degree of accuracy transmission shaft for tractor, this transmission shaft includes axle body 1, axle body 1 includes the multidiameter shaft 12 at main shaft 11 and moulding and these main shaft two ends, axle body 1 is distributed with the double wedge 2 arranging vertically on the outer circumferential face of main shaft 11, on the outer circumferential face of the multidiameter shaft end of main shaft both sides, also there is the double wedge 2 arranging vertically, between adjacent double wedge 2, form keyway arrangements.Wherein, the double wedge 2 on axle body 1, along the uniform setting of outer circumferential face of axle body 1, in order to facilitate processing and assembling, is formed in one between double wedge 2 and axle body 1.
The transmission shaft of the present embodiment is when assembling, can realize and the coordinating of axle sleeve by the double wedge on axle body and keyway arrangements, thereby carry out circumferentially locating fast, prevent the rotation of axle, registration soundness while improving assembling, guarantees the transfer reliability of transmission shaft and handles portability.
