Background technology
Retainer, refers to and partly wrap up all or part of rolling element, and the bearing parts for moving therewith, is used to isolate
Rolling element, generally also guides rolling element and holds it in bearing.
Referring to Fig. 1 and Fig. 2, the retainer of the traditional bearing be given in figure, including retainer body 10, retainer body
10 are arranged between bearing inner race 20 and bearing outer ring 30, and some being used for is provided with the side wall of the annular of retainer body 10
The pocket hole 11 of rolling element 40 is installed, the inner face in pocket hole 11 is spherical structure, because the inner face in pocket hole 11 is spherical structure, rolling element
40 is larger with the contact surface in pocket hole 11, thus friction during bearing working between rolling element 40 and pocket hole 11 is also big, so not only
Rolling element 40 can be worn and torn greatly, the fragmentation of rolling element 40 or the stuck phenomenon of rolling element 40 easily occur, and retainer also can
Service life is caused to greatly shorten because of abrasion；Another, the retainer overall structure of traditional bearing is complex and resistance to
Mill poor-performing, larger inconvenience is brought to user.
But in view of the shortcomings of the prior art, developer is necessary to develop a kind of reasonable in design, simple structure, can reduce
Second pocket hole and the contact area of rolling element, effectively reduce the abrasion of rolling element and retainer, and anti-wear performance is good and makes
With the modified form low friction retainer of the bearing of long lifespan.
The content of the invention
To solve the problems, such as prior art, the object of the invention provides a kind of reasonable in design, simple structure, can subtract
The contact area of few second pocket hole and rolling element, effectively reduces the abrasion of rolling element and retainer, anti-wear performance it is good with
The modified form low friction retainer of the bearing of long service life.
To solve above technical problem, what the present invention was realized using following technical scheme：
A kind of modified form low friction retainer of bearing, including the entirety being arranged between bearing inner race and bearing outer ring is in
The retainer body of annular, be evenly distributed with the side wall of the annulus of the retainer body for rolling element is installed
One pocket hole and the second pocket hole, it is characterised in that the inner surface in the first pocket hole is spherical structure, the bottom surface in the second pocket hole
It is planar structure, two sides in the second pocket hole are barrel surface structure, and rolling element is crossed in the axis in the second pocket hole
The centre of sphere.
In a preferred embodiment of the invention, the first wearing layer is provided with the inner surface in the first pocket hole,
The bottom surface and side in the second pocket hole are provided with the second wearing layer.
In a preferred embodiment of the invention, the quantity in the first pocket hole is 4-8, the number in the second pocket hole
Measure is 19-23.
In a preferred embodiment of the invention, the quantity in the first pocket hole is 4, the quantity in the second pocket hole
It is 19.
Compared with prior art, the present invention is evenly distributed with the side wall of the annulus of retainer body for installing rolling
The first pocket hole and the second pocket hole of body, the inner surface in the first pocket hole is spherical structure, and the bottom surface in the second pocket hole is planar structure, the
Two sides in two pocket holes are barrel surface structure, and the axis in the second pocket hole crosses the centre of sphere of rolling element, are adopted the structure the
Face between two pocket holes and the bottom surface and side of rolling element contacts to be changed into and a little contacts, and reduces rolling element and the second pocket hole
Contact area, effectively reduces the abrasion of rolling element and retainer.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Shown in reference picture 3- Fig. 5, a kind of modified form low friction retainer of the bearing be given in figure, including it is arranged on bearing
Retainer body 100 between inner ring 200 and bearing outer ring 300, it is in annular that retainer body 100 is overall.
The first pocket hole 110 for installing rolling element 400 is evenly distributed with the side wall of the annulus of retainer body 100
With the second pocket hole 120.
The inner surface 111 in the first pocket hole 110 is spherical structure, and the bottom surface 121 in the second pocket hole 120 is planar structure, second
Two sides 122,123 in pocket hole 120 are barrel surface structure, and the axis in the second pocket hole 120 is crossed the centre of sphere of rolling element 400, adopted
The face between bottom surface 121 and side 122,123 with this kind of structure by the second pocket hole 120 with rolling element 400 contacts and is changed into
Point contact, reduces the contact area in the pocket hole 120 of rolling element 400 and second, effectively reduces rolling element and retainer
Abrasion.
The first wearing layer is provided with the inner surface 111 in the first pocket hole 110, in the bottom surface 121 and side in the second pocket hole 120
Face 122,123 is provided with the second wearing layer, and the first wearing layer is effectively combined with the second wearing layer, can effectively improve first
The anti-wear performance in the pocket hole 120 of pocket hole 110 and second, further increases the anti-wear performance of the retainer.
The quantity in the first pocket hole 110 is 4-8, and the quantity in the second pocket hole 120 is 19-23, in the present embodiment first
The quantity in pocket hole 110 is 4, and the quantity in the second pocket hole 120 is 19, and 19 the second pocket holes 120 are evenly distributed in retainer
On the side wall of body 100, and 4 the first pocket holes 110 are evenly distributed on the side wall of retainer body 100, adjacent first pocket
Angle between hole 110 is 90 °.
In sum the present invention be evenly distributed with the side wall of the annulus of retainer body for rolling element is installed the
One pocket hole and the second pocket hole, the inner surface in the first pocket hole is spherical structure, and the bottom surface in the second pocket hole is planar structure, the second pocket hole
Two sides be barrel surface structure, the axis in the second pocket hole is crossed the centre of sphere of rolling element, is adopted the structure the second pocket hole
And the face between the bottom surface and side of rolling element contacts to be changed into and a little contacts, the contact surface in rolling element and the second pocket hole is reduced
Product, effectively reduces the abrasion of rolling element and retainer.
