Abstract
The utility model discloses an inner ball cage fine forge piece with the uniform wall thickness. The inner ball cage fine forge piece comprises a tubular part, a spline part and a die cavity part, wherein the die cavity part is arranged at the tubular part, the tubular part, the spline part and the die cavity part are respectively formed through forging, the spline part is arranged at one end of the tubular part, and the outer wall shape of the tubular part is in a circular arc shape matched with the shape of the inner wall of the die cavity part. The wall thickness of the tubular part of the inner ball cage fine forge piece is uniform, the heat treatment deformation quantity is uniform, and the matching precision of the inner ball cage fine forge piece and a three-pin-shaft assembly is ensured.
Description
Technical field
The utility model relates to a kind of universal joint finish forge spare, relates in particular to a kind of internal spherical cage finish forge spare.
Background technique
Automobile is that automobile is realized the mechanical part that the break-in of power and moment of torsion is transmitted with the constant velocity universal joint assembly, and this function 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.Existing internal spherical cage is processed by foundry goods; Tubular partly is generally circle, and die cavity part inwall is a circular arc, like this; The wall thickness of internal spherical cage tubular part will be inconsistent; Amount of deformation is inconsistent when heat-treating, and can influence the precise measure of internal spherical cage die cavity part, thereby reduces the quality of fit of the three bearing pin assemblies that are mated.
The model utility content
The purpose of the utility model is to provide a kind of cylindrical portion wall thickness internal spherical cage finish forge spare more uniformly.
The utility model solves the technological scheme that its technical problem adopted: a kind of internal spherical cage finish forge spare; It is characterized in that: comprise tubular part, splined section and the die cavity part that in the tubular part, forms, said tubular part, splined section and die cavity partly are to forge and form; Splined section is arranged on an end of tubular part; The outer wall of said tubular part is shaped as the suitable circular arc of inner wall shape with the die cavity part.
The beneficial effect of the utility model is: formed by casting with general internal spherical cage and compare, the utility model forms for forging, and the cylindrical portion wall ratio is more even; Make its heat treatment deformation amount consistent; Guarantee the quality of fit of itself and three bearing pin assemblies, simultaneously, also alleviated the overall weight of part; Save material, reduced the power consumption of automobile.
Description of drawings
Fig. 1 is the internal spherical cage finish forge spare structural representation of the utility model.
Be labeled as among the figure: 1, tubular part, 2, splined section, 3, the die cavity part.
Embodiment
Describe the particular content of the utility model in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, internal spherical cage finish forge spare comprises: tubular part 1, splined section 2 and the die cavity part 3 that in tubular part 1, forms, and tubular part 1, splined section 2 and die cavity part 3 are to forge and form; Splined section 2 is arranged on an end of tubular part 1; The outer wall of tubular part 1 is shaped as and the suitable circular arc of the inner wall shape of die cavity part 3.
Above-mentioned internal spherical cage finish forge spare is compared with general internal spherical cage finish forge spare, and the cylindrical portion wall ratio is more even, makes its heat treatment deformation amount consistent; Guarantee the quality of fit of itself and three bearing pin assemblies, simultaneously, also alleviated the overall weight of part; Save material, reduced the power consumption of automobile.
