Abstract
The utility model is a kind of ball-bearing retainer, comprises support body cylindrically, described support body offers the window for fixing ball, and window is polished by ball-type bistrique and formed.Polishing so just can be made more convenient, and the window polished is very level and smooth, the degree of depth only needing setting program just can control to polish and length.
Description
technical field:
The utility model relates to ball bearing field, particularly a kind of ball-bearing retainer.
background technique:
Retainer is in internal spherical cage or external ball cage, or in bearing, for the support body of fixing ball, traditional retainer window is the square of rule, but this structure is when grinding two sides, the length of grinding is difficult to control, and it is also more difficult to locate, the degree of depth also bad control of grinding.
And the window of existing retainer is all generally formed after carrying out rough polishing to window after punching press, the edge of window is therefore also comparatively sharp, and long-time use easily makes ball damage.
model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of ball-bearing retainer, and the length solving grinding is difficult to control, and it is also more difficult to locate, the degree of depth also bad control of grinding, the problem that long-time use easily makes ball damage.
Technology solution of the present utility model is as follows:
A kind of ball-bearing retainer, comprise support body cylindrically, described support body offers the window for fixing ball, window is near oval, the circumferencial direction of the long edge support body of window is arranged, the circular arc of 1/25 circle of to be diameter be on the long limit of the described window circle of 12 times ~ 14 times of ball diameters, the circular arc of the minor face of described window to be diameter be 1/6 circle of the circle of 2 times of ball diameters.So just make the movement of ball in window more smooth and easy.
As preferably, the center line of window is overlapping with the circumference of support body center height.
As preferably, window has 6, is evenly distributed on the circumference of support body center height in array.
As preferably, support body internal surface also forms along support body circumferencial direction the circular groove that diameter is 1/8 circle of the circle of 3 times of ball diameters.
As preferably, the edge of window is flange, the circular arc of described flange to be diameter be 1/6 circle of the circle of ball diameter.
The beneficial effects of the utility model are:
The circular arc of 1/25 circle of to be diameter be on the long limit of the window of the present utility model circle of 12 times ~ 14 times of ball diameters, the circular arc of 1/6 circle of the minor face of described window to be diameter the be circle of 2 times of ball diameters, the edge of window is flange, the circular arc of 1/6 circle of flange to be diameter the be circle of ball diameter, above-mentioned parameter is all the data drawn after staff repeatedly attempts and tests, the utility model is polished after adopting such data to carry out punching press to ball-bearing retainer, make ball can carry out the slip of side direction very smoothly in window of the present utility model, and the working life of ball improves more than 30%, the accuracy of ball location have also been obtained great lifting.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
In figure: support body 1; Window 2; Circular groove 3.
embodiment:
Embodiment 1: a kind of ball-bearing retainer as shown in Figure 1, comprise support body 1 cylindrically, window 2 is near oval, the circumferencial direction of the long edge support body of window 2 is arranged, the circular arc of 1/25 circle of to be diameter be on the long limit of described window 2 circle of 12 times of ball diameters, the circular arc of the minor face of described window 2 to be diameter be 1/8 circle of the circle of 2 times of ball diameters.
The center line of window 2 is overlapping with the circumference of support body 1 center height.
Window 2 has 6, is evenly distributed on the circumference of support body 1 center height in array.
Support body 1 internal surface also forms along support body circumferencial direction the circular groove 3 that diameter is 1/8 circle of the circle of 3 times of ball diameters.
The edge of window is flange, the circular arc of 1/6 circle of described flange to be diameter the be circle of ball diameter.
The present embodiment is polished after adopting such data to carry out punching press to ball-bearing retainer, make ball can carry out the slip of side direction very smoothly in window of the present utility model, and the working life of ball improves more than 31%, the accuracy of ball location have also been obtained great lifting.
Embodiment 2: a kind of ball-bearing retainer as shown in Figure 1, comprise support body 1 cylindrically, window 2 is near oval, the circumferencial direction of the long edge support body of window 2 is arranged, the circular arc of 1/25 circle of to be diameter be on the long limit of described window 2 circle of 13 times of ball diameters, the circular arc of the minor face of described window 2 to be diameter be 1/8 circle of the circle of 2 times of ball diameters.
The center line of window 2 is overlapping with the circumference of support body 1 center height.
Window 2 has 6, is evenly distributed on the circumference of support body 1 center height in array.
Support body 1 internal surface also forms along support body circumferencial direction the circular groove 3 that diameter is 1/8 circle of the circle of 3 times of ball diameters.
The edge of window is flange, the circular arc of 1/6 circle of described flange to be diameter the be circle of ball diameter.
The present embodiment is polished after adopting such data to carry out punching press to ball-bearing retainer, make ball can carry out the slip of side direction very smoothly in window of the present utility model, and the working life of ball improves 33%, the accuracy of ball location have also been obtained great lifting.
Embodiment 3: a kind of ball-bearing retainer as shown in Figure 1, comprise support body 1 cylindrically, window 2 is near oval, the circumferencial direction of the long edge support body of window 2 is arranged, the circular arc of 1/25 circle of to be diameter be on the long limit of described window 2 circle of 14 times of ball diameters, the circular arc of the minor face of described window 2 to be diameter be 1/8 circle of the circle of 2 times of ball diameters.
The center line of window 2 is overlapping with the circumference of support body 1 center height.
Window 2 has 6, is evenly distributed on the circumference of support body 1 center height in array.
