Abstract
The utility model discloses a split type differential spider structure belongs to engineering machine parts field. It is including a word axle of two cross arrangements, and a word axle includes the intermediate journal and establish the tip axle journal at middle diameter of axle both ends, and the intermediate journal diameter is greater than the diameter of tip axle journal, and is provided with the constant head tank on it, the shape of the constant head tank of two one word axles is corresponding, on the tip axle journal of intermediate journal both sides still respectively the symmetry be provided with the major axis recess. The utility model relates to a processing is simple, and application scope is wide, the low differential spider of production cost of maintenance.
Description
Technical field
The utility model relates to a kind of Engineering Machinery Components, specifically, particularly relates to a kind of split type differential spider structure.
Background technique
Traditional differential spider structure is all integrated type cross axle, and the cross axle of this solid forging has following defect: the cross axle of (1) solid forging exists forging defect, and vehicle running environment badly can cause cross axle to rupture; (2) on four axles of integrated type cross axle and the differential casing that coordinates with it for assembling the axis hole of cross axle, adding, position degree requirement in man-hour is high, and precision not easily ensures, processing cost is high; (3) when differential spider wearing and tearing need repairing time, replacing cross axle that can only be overall, adds the cost of maintenance.
Model utility content
In order to overcome above-mentioned defect, it is simple, applied widely that the purpose of this utility model is to provide a kind of processing, production, the differential spider that maintenance cost is low.
The utility model is achieved through the following technical solutions: a kind of split type differential spider structure, include two word axles arranged in a crossed manner, a described word axle comprises intermediate journal and is located at the end axle journal at medium axle diameter two ends, described intermediate journal diameter is greater than the diameter of end axle journal, and be provided with locating slot, the shape of the locating slot of described two word axles is corresponding, and the end axle journal of described intermediate journal both sides is also symmetrically arranged with major axis groove respectively.
Preferably, when the locating slot of one of them word axle snaps in the locating slot of another word axle, two 1 word axles are orthogonal and mutually coplanar.
Preferably, intermediate journal length is 1/3 of a word shaft length.
Preferably, locating slot is rectangle groove.
Preferably, locating slot is U-groove bevel.
Preferably, locating slot is positioned at the central position of described intermediate journal.
Preferably, a word shaft length is 100-300mm, and the diameter of axle of institute's intermediate journal is 20-40mm, and the diameter of axle of end axle journal is 15-35mm.
Preferably, the distance between major axis bottom portion of groove to top is 12mm-30mm.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model differential spider is split-type design, makes the processing of cross axle and differential casing, all need not ensure the required precision of position degree, decrease processing charges;
(2) in the utility model, the structure of a word axle is simply easy to processing, does not need custom mold, directly adopts cylindrical bar to process;
(3) when keeping in repair the utility model, as needs are changed cross axle, need not whole set replacement be carried out, only change the word axle damaged, decrease maintenance expenses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan view of a word axle of the present utility model;
Fig. 3 is the plan view of a word axle of the present utility model.
In figure: 1, a word axle; 2, end axle journal; 3, locating slot; 4, intermediate journal; 5, major axis groove.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, a kind of split type differential spider structure, includes the end axle journal 2 that fixing word axle 1, the word axle 1 of two criss-crossings comprises intermediate journal 4 and is located at intermediate journal 4 two ends.The diameter of intermediate journal 4 is larger than end axle journal 2 diameter, its objective is increase structural strength, and its length is 1/3 of word axle 1 length, by round-corner transition between each joint, to ensure the structural strength of a word axle 1; In the middle part of one word axle 1, central position is provided with a locating slot 3, locating slot 3 is rectangle groove or U-groove bevel, rounding bottom locating slot 3, the shape of the locating slot 3 of two word axles 1 is corresponding, when locating slot 3 position of a described word axle 1 snaps in the locating slot 3 of another word axle 1 described, two word axles 1 are orthogonal, and mutually coplanar.The both sides one word axle 1 being positioned at locating slot 3 are also respectively arranged with major axis groove 5, two major axis grooves 5 are symmetrically located at the both sides of word axle 1 long axis ray respectively, in order to coordinate with bevel gear pad rectangular opening, bevel gear pad is stoped to rotate relative to the axis of a word axle.
One word axle 1 length is 100-300mm, and the diameter of axle of intermediate journal 4 is 20-40mm, and the diameter of axle of end axle journal 2 is 15-35mm; Bottom major axis groove 5 to the distance between top be 12mm-30mm.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; those of ordinary skill in the art is to be understood that; every the technical solution of the utility model is carried out any simple modification, change and equivalent structure change, it all should be encompassed in the protection domain of technical solutions of the utility model.
