Abstract
The present invention is a kind of ball-bearing retainer, including support body cylindrically, described support body offers the window for fixing ball, and window is formed by the polishing of ball-type bistrique.Polishing thus can be made more convenient, and the window polished is the most smooth, only needs setting program just can control the degree of depth and the length of polishing.
Description
Technical field:
The present invention relates to ball bearing field, particularly to a kind of ball-bearing retainer.
Background technology:
Retainer is in internal spherical cage or external ball cage, or in bearing, for fixing the support body of ball, traditional retainer window is the square of rule, but this structure is two sides of grinding when, the length of grinding is difficult to control, and it is the most difficult to position, the most bad control of the degree of depth of grinding.
And formed after window being polished roughly after the window typically all punching press of existing retainer, the edge of window is the sharpest, and long-time use easily makes ball damage.
Summary of the invention:
The purpose of the present invention is aiming at the deficiency of prior art, and provides a kind of ball-bearing retainer, and the length solving grinding is difficult to control, and it is the most difficult to position, the most bad control of the degree of depth of grinding, and long-time use easily makes the problem that ball damages.
The technology solution of the present invention is as follows:
A kind of ball-bearing retainer, including support body cylindrically, described support body offers the window for fixing ball, after window is by punch press punching press, then is formed by the polishing of ball-type bistrique.The operation that thus can make the molding of window is the most reasonable, and window edge polishing is more convenient, and the window polished is the most smooth, and Superfinishing machine setting program only need to just can control the radian to window polishing and length.
As preferably, window is near oval, the circumferencial direction of the long edge support body of window is arranged, and the long limit of described window is the circular arc of 1/25 circle of the circle of a diameter of 12 times～14 times ball diameters, and the minor face of described window is the circular arc of 1/6 circle of the circle of a diameter of 2 times of ball diameters.Thus make ball movement in window more smoothly.
As preferably, the centrage of window is overlapping with the circumference of support body centre-height.
As preferably, window has 6, is evenly distributed in array on the circumference of support body centre-height.
As preferably, support body inner surface also forms the circular groove of 1/8 circle of the circle of a diameter of 3 times of ball diameters along support body circumferencial direction.
As preferably, the edge of window is flange, and described flange is the circular arc of 1/6 circle of the circle of a diameter of ball diameter.
The beneficial effects of the present invention is:
1, the window of the present invention is formed by the polishing of ball-type bistrique, makes polishing more convenient, and the window polished is the most smooth, only needs setting program just can control the degree of depth and the length of polishing；
2, the long limit of the window of the present invention is the circular arc of 1/25 circle of the circle of a diameter of 12 times～14 times ball diameters, the minor face of described window is the circular arc of 1/6 circle of the circle of a diameter of 2 times of ball diameters, the edge of window is flange, flange is the circular arc of 1/6 circle of the circle of a diameter of ball diameter, above-mentioned parameter is all the data drawn after staff repeatedly attempts and tests, the present invention uses such data to polish after ball-bearing retainer carries out punching press, make ball can carry out lateral slip in the window of the present invention the most smoothly, and improve more than 30% the service life of ball, the accuracy of ball location have also been obtained lifting greatly.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention；
In figure: support body 1；Window 2；Circular groove 3.
Detailed description of the invention:
Embodiment 1: a kind of ball-bearing retainer as shown in Figure 1, including support body 1 cylindrically, described support body 1 offers the window 2 for fixing ball, after window 2 is by punch press punching press, then is formed by the polishing of ball-type bistrique.
Window 2 is near oval, and the circumferencial direction of the long edge support body of window 2 is arranged, and the long limit of described window 2 is the circular arc of 1/25 circle of the circle of a diameter of 12 times of ball diameters, and the minor face of described window 2 is the circular arc of 1/8 circle of the circle of a diameter of 2 times of ball diameters.
The centrage of window 2 is overlapping with the circumference of support body 1 centre-height.
Window 2 has 6, is evenly distributed in array on the circumference of support body 1 centre-height.
Support body 1 inner surface also forms the circular groove 3 of 1/8 circle of the circle of a diameter of 3 times of ball diameters along support body circumferencial direction.
The edge of window is flange, and described flange is the circular arc of 1/6 circle of the circle of a diameter of ball diameter.
The present embodiment uses such data to polish after ball-bearing retainer carries out punching press, make ball can carry out lateral slip in the window of the present invention the most smoothly, and improve more than 31% the service life of ball, the accuracy of ball location have also been obtained lifting greatly.
Embodiment 2: a kind of ball-bearing retainer as shown in Figure 1, including support body 1 cylindrically, described support body 1 offers the window 2 for fixing ball, after window 2 is by punch press punching press, then is formed by the polishing of ball-type bistrique.
Window 2 is near oval, and the circumferencial direction of the long edge support body of window 2 is arranged, and the long limit of described window 2 is the circular arc of 1/25 circle of the circle of a diameter of 13 times of ball diameters, and the minor face of described window 2 is the circular arc of 1/8 circle of the circle of a diameter of 2 times of ball diameters.
The centrage of window 2 is overlapping with the circumference of support body 1 centre-height.
Window 2 has 6, is evenly distributed in array on the circumference of support body 1 centre-height.
