Abstract
The utility model relates to a constant velocity universal joint, in particular to an external ball cage of a universal joint. The external ball cage of a universal joint comprises a bell shell, a retaining support, steel balls and a star sleeve, wherein the retaining support, the steel balls and the star sleeve are arranged in the bell shell; channels of the bell shell and the star sleeve are both eight, and eight steel balls are arranged in the retaining support matched with the bell shell and the star sleeve; the centers of the eight channels of the bell shell and the center of an internal ball surface are concentric and are equally arranged; the centers of the eight channels of the star sleeve and the center of an external ball surface are concentric and are equally arranged; and the channels of the bell shell and the star sleeve are corresponding one by one. The eight-channel and eight-steel ball arrangement sufficiently uses the space in the bell shell, and the flexible rotation of the external ball cage is not affected, so the bearing ability of the universal joint using the external ball cage is greatly improved, and meanwhile, the use life of the universal joint is also improved. The external ball cage is used to the constant velocity universal joint.
Description
Technical field
The utility model relates to constant velocity universal joint, particularly a kind of universal joint ectosphere cage.
Background technique
Constant velocity universal joint is when master and slave moving axis has angular displacement, can transmitting movement and the mechanism of torque.
The structure of constant velocity universal joint of the prior art is that outer race and star sleeve are six raceway grooves, and six groove curvature centers of outer race and six groove curvature centers of star sleeve, be positioned at the Rzeppa type retainer respectively, both sides, outer spherical surface center, and throw of eccentric all equates, but such raceway groove is provided with following deficiency: outer race and star sleeve all are six equally distributed raceway grooves on circumference, six steel ball work are promptly arranged in rzeppa universal joint, this structure does not make full use of enough inner spaces, make that the bearing stress of universal joint is lower, can not bear the moment that produces when turning to for a long time, cause reduce the working life of this kind universal joint.
The model utility content
The purpose of this utility model provides a kind of universal joint ectosphere cage, and it makes full use of its inner space, has greatly improved the bearing capacity of ectosphere cage.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of universal joint ectosphere cage, it comprises outer race and is positioned at the retainer of outer race, steel ball, star sleeve, outer race and star sleeve all are provided with eight raceway grooves, with steel ball number in the retainer that outer race, star sleeve match is eight, and the center of eight raceway grooves of described outer race and inner ball surface centres and five equilibrium are arranged; Eight raceway groove centers of star sleeve and outer spherical surface centres and five equilibrium are arranged; Outer race is corresponding one by one with the raceway groove of star sleeve.The setting of eight raceway grooves and eight steel balls has made full use of the space in the outer race and has not influenced the flexible rotation of ectosphere cage, has greatly improved the bearing capacity of the universal joint of using this kind ectosphere cage, the working life of also having improved above-mentioned universal joint simultaneously.
As of the present utility model preferred, the outer race front end is provided with axial involute splines and oblique involute splines, and axially involute splines is positioned at the front end of oblique involute splines.Axially involute splines and oblique involute splines are used for this kind universal joint ectosphere cage is fixed in the automotive wheel skeleton; The spline that two kinds of different direction are set make between ectosphere cage and the skeleton be connected more firm, transmitting torque and motion better.
As of the present utility model further preferred, the tooth pitch of described oblique involute splines is 20mm to 30mm, and the maximum diameter of outer race outer wall is 70mm to 75mm.
In sum, the utlity model has following beneficial effect:
1, the setting of eight raceway grooves and eight steel balls has made full use of the space in the outer race and has not influenced the flexible rotation of ectosphere cage, has greatly improved the bearing capacity of the universal joint of using this kind ectosphere cage, the working life of also having improved above-mentioned universal joint simultaneously;
2, the spline that two kinds of different direction are set make between ectosphere cage and the skeleton be connected more firm, transmitting torque and motion better.
