Abstract
The invention discloses a flange type inner ball cage fine forge piece, which is positioned firmly. The flange type inner ball cage fine forge piece comprises a cylindrical part and a cavity part, wherein the cavity part is arranged on the cylindrical part; the cylindrical part has a circular shape; the cavity part is a blind hole; and one end, at the bottom of the cavity part, of the cylindrical part is connected with a flange edge part. Compared with the common inner ball cage, the flange type inner ball cage fine forge piece has the advantages that: the flange type inner ball cage fine forge piece has a simple structure and is convenient to assemble and disassemble; the flange type inner ball cage fine forge piece is connected with the output part of a differential mechanism through bolts, so the flange type inner ball cage fine forge piece is positioned firmly and the strength and the transmission torque of products are greatly enhanced; an automobile is safer when the flange type inner ball cage fine forge piece is used on the automobile; manufacturing procedures are reduced and equipment investment generated by the manufacturing procedures is saved; and production cycle is greatly shortened.
Description
Technical field
The present invention relates to a kind of finish forge spare, relate in particular to a kind of flange-type internal spherical cage finish forge spare.
Background technique
Automobile be mounted between automobile differential and the wheel hub with the constant velocity universal joint assembly or terminal gear of gearbox and wheel hub between be used for the mechanical part of transferring power and moment of torsion.The input shaft of constant velocity universal joint assembly and output shaft compare transmitting movement to equal 1 instantaneous angular velocity, in transferring power and moment of torsion, go back the synchronous change operating angle, stretch slippage with the axially variation of size in the compensation transmission device, and above-mentioned functions is mainly realized by internal spherical cage in the constant velocity universal joint assembly and ectosphere cage.Internal spherical cage is the automotive safety parts, to very high requirement is all arranged in its intensity, precision, Safety performance and working life.As shown in Figure 1, the structure of traditional internal spherical cage comprises: cylindrical portion 1, splined section 2 and be arranged on die cavity part 3 on the cylindrical portion 1, cylindrical portion 1 be shaped as circle, die cavity part 3 is a blind hole.Traditional internal spherical cage is to utilize spline to be connected with differential mechanism, find to exist following defective in its manufacture process and using process: the spline position that is connected with differential mechanism relies on jump ring spacing, intensity, driving torque and working life are all not ideal enough, and easily produce quenching stress after the heat treatment of spline position and cause spline position longitudinal cracking, again because inside and outside spline is a Spielpassung, the long-term use can form key tooth early failue pattern, sluggish when causing transferring power, moment of torsion causes automobile steering excesssive gap even skew and the traffic safety accident takes place.
Summary of the invention
Technical problem to be solved by this invention is: a kind of firm flange-type internal spherical cage finish forge spare of locating is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: flange-type internal spherical cage finish forge spare, comprise: cylindrical portion and the die cavity part that is arranged on the cylindrical portion, cylindrical portion be shaped as circle, die cavity partly is a blind hole, is connected with the flange edge part on the end of described die cavity part bottom cylindrical portion.
In order to solve the problems of the technologies described above better, the further technological scheme that the present invention adopts is: described die cavity partly is three pin structures, evenly is provided with three bolt joints on the outside of described flange edge part.
Advantage of the present invention is: above-mentioned flange-type internal spherical cage finish forge spare is compared with common internal spherical cage, simple structure, is convenient to dismounting; Utilize bolt and differential mechanism output position to be connected, it is firm locate, and product strength and driving torque strengthen greatly, uses safelyr on automobile, has reduced manufacturing process and has saved so the equipment investment of generation, has shortened the manufacture cycle greatly.
Description of drawings
Fig. 1 is the structural representation of internal spherical cage finish forge spare traditional in the background technique of the present invention.
Fig. 2 is the structural representation of flange-type internal spherical cage finish forge spare of the present invention.
Among the figure: 1, cylindrical portion, 2, splined section, 3, the die cavity part, 4, cylindrical portion, 5, the die cavity part, 6, the flange edge part, 7, the bolt joint.
Embodiment
Describe particular content of the present invention in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 2, flange-type internal spherical cage finish forge spare comprises: cylindrical portion 4 and be arranged on die cavity part 5 on the cylindrical portion 4, cylindrical portion 4 be shaped as circle, die cavity part 5 is a blind hole, is connected with flange edge part 6 on the end of described die cavity part 5 bottom cylindrical portions 4.
As shown in Figure 2, in the present embodiment, described die cavity part 5 is three pin structures, evenly is provided with three bolt joints 7 on the outside of described flange edge part 6.In actual application, as required, the shape of flange edge part 6 also can be circular or in four～six bolt joints 7 of arranged outside of flange edge part 6; Described die cavity part 5 also can be six pearl structures.
Above-mentioned flange-type internal spherical cage finish forge spare is compared with common internal spherical cage, simple structure, is convenient to dismounting; Utilize bolt and differential mechanism output position to be connected, it is firm locate, and product strength and driving torque strengthen greatly, uses safelyr on automobile, has reduced manufacturing process and has saved so the equipment investment of generation, has shortened the manufacture cycle greatly.
The foregoing description is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the present invention's spirit and protection domain; can also make various variations and modification, so all technological schemes that are equal to also should belong to protection category of the present invention.
