It is often used；
2, by the setting of groove, can play makes the surface of grafting block there are gap, increases the elasticity of grafting block itself,
Be conducive to needle roller during being installed on needle roller window, grafting block is squeezed and deformed by needle roller, so that needle roller be allow to install
It is stronger while guaranteeing the not damaged effect of the structure of grafting block.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the plastic cage ontology of the utility model.
In figure, 1, cylindric retainer ontology；2, needle roller window；3, oil storage tank；4, notch；5, grafting block；6, groove.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: a kind of auto pump bearing plastic cage, referring to Fig.1, including cylindric retainer ontology 1, circle
Several needle roller windows 2 are offered on the side wall of tubular retainer ontology 1, needle roller window 2 is arranged in rectangle, between needle roller window 2 waits
Away from being located on the side wall of cylindric retainer ontology 1, and it is located at the upper half of the side wall, the side of cylindric retainer ontology 1
Oil storage tank 3 is provided on wall on the end face of 2 one end of needle roller window, oil storage tank 3 and cylindric retainer ontology 1 are integrally formed
And be located on the end face, the opening of oil storage tank 3 is arranged backwards to cylindric retainer ontology 1, and the opening of oil storage tank 3 is in opening
Shape setting.Offering 5 notches 4 on the lateral wall of oil storage tank 3, notch 4 is in U-shape setting, and equidistant point respectively of 5 notches 4
It is distributed on the lateral wall of oil storage tank 3.The setting of notch 4 can make the side wall of oil storage tank 3 there are several gaps, these gaps can be with
So that retainer is made retainer when loading needle roller, being caught in bearing, there are certain deformation spaces, to increase the bullet of retainer
Property, make retainer avoid mechanism impaired during the installation process, needle roller firmly installs, and is not susceptible to play, guarantees the normal of bearing
It uses.
Wherein, the quantity setting of notch 4 excessively be easy to cause the gap on 3 outer wall of oil storage tank between adjacent gap 4 too small,
Fragile structure so as to cause 3 side wall of oil storage tank is not firm, and the setting of 4 quantity of notch is very few to be easy to cause phase on 3 outer wall of oil storage tank
Gap between adjacent notch 4 is excessive, increases the protection that effect is unobvious, to retainer structure for the elasticity of 3 side wall of oil storage tank
Ineffective, 5 notches 4 are set as optimal installation number, can either guarantee to play the elasticity for increasing retainer, and can be with
Guarantee the firm of 3 side wall of oil storage tank.
Referring to Fig.1,3 lateral wall of oil storage tank with a thickness of 0.15mm, the excessively thin easy reduction side wall strength of sidewall thickness causes
The side wall of oil storage tank 3 during using, installing of retainer ontology 1 is extruded damage, and sidewall thickness then will affect side later
The elasticity of wall itself, the side wall of 0.15mm thickness can either guarantee that the elasticity of side wall itself can guarantee the intensity of side wall construction again.
Referring to Fig.1, several grafting blocks 5 are fixedly connected on the side wall of cylindric retainer ontology 1, grafting block 5 distinguishes position
It is arranged on side wall between adjacent needle roller window 2 and along the bottom surface direction perpendicular to oil storage tank 3, the cross section of grafting block 5 is in
Isosceles trapezoid setting.Grafting block 5 can make retainer more firmly grafting within the bearing, while grafting block 5 is located at adjacent needle roller
The contact area for being conducive to increase needle roller window 2 and needle roller between window 2, allows needle roller is stronger to be fastened on needle roller window
In 2.Grafting block 5 be set as isosceles trapezoid be conducive to grafting block 5 and bearing clamping it is stronger, prevent bearing during operating
The case where retainer rotates, misplaces.
Referring to Fig.1, grafting block 5 opens up fluted 6 backwards to the side wall of cylindric retainer ontology 1, and groove 6 is along grafting block 5
Length direction setting and being penetrated through with notch 4 connect, the inner wall of groove 6 is in arc-shaped setting.Groove 6 can make grafting block 5
There are gaps on surface, increase the elasticity of grafting block 5 itself, are conducive to needle roller during being installed on needle roller window 2, grafting block
5 are squeezed and deformed by needle roller, to allow that needle roller installs stronger while guarantee that the structure of grafting block 5 is not damaged.Wherein,
The inner wall of arc-shaped can make grafting block 5, and groove 6 can be with uniform stressed, so that grafting block 5 be avoided to exist in the process of being squeezed
It is broken during being extruded.
Referring to Fig.1, the side wall of needle roller window 2 is arranged in arc-shaped, and the bottom center of needle roller window 2 is lower than inside and outside it
Side.The side wall of arc-shaped can reduce the frictional force between the surface and needle roller of needle roller window 2, and the smoothness for being conducive to needle roller turns
It is dynamic, guarantee the efficient stable operation of bearing.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
