Description
Technical Field
The utility model relates to a bearing nylon holder.
Background
Needle bearing indicates that the roller is long and thin columniform bearing, and this bearing still is provided with the holder that is used for separating, guiding a plurality of rollers except including a plurality of rollers, the common adoption metal of material of holder or nylon material constitute, the holder is including support body and a plurality of axial roof beam, the support body be the annular, a plurality of axial roof beam axial equipartition on the support body, be formed with the rectangular form pocket hole that supplies the roller holding between the adjacent axial roof beam, the inner wall in pocket hole is the arc surface, is convenient for laminate with the roller.
However, in the cage of the prior art, because the inner wall of the pocket can be attached to the peripheral wall of the roller, grease can not enter between the inner wall of the pocket and the roller easily, so that the bearing is not lubricated enough during operation and is easy to damage, and the clearance is generated between the pocket and the roller by increasing the size of the pocket, so that the play amount of the roller is increased, and the stability of the bearing is affected.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a bearing nylon holder, it is favorable to the lubrication between roller and the pocket hole, and stability is strong.
In order to realize the above object, the utility model provides a needle bearing nylon retainer, including the axial roof beam, be formed with the pocket hole between the adjacent axial roof beam, the axial roof beam on be provided with a plurality of planar butt faces that are, a plurality of butt faces link to each other to be set up and arrange along roller circumference, be the butt cooperation between a plurality of butt faces and the roller, and be formed with the oil storage clearance between adjacent butt face and the roller, the pocket hole constitute by opposite butt face between the adjacent axial roof beam.
The technical scheme has the advantages that: through being the avoiding of arc surface by two original with the pocket hole and improving into by the pocket hole by between the adjacent axial roof beam in opposite directions a plurality of be the plane butt face and constitute, on the one hand, the contact of roller and pocket hole inner wall, become the line contact that a plurality of butt faces constitute by original face contact, can reduce the area of contact between roller and the holder, on the other hand, do not influence the pocket hole size, on the basis of the volume of scurrying between pocket hole and the roller, by forming the oil storage space between adjacent butt face and the roller, lubrication between roller and the pocket hole inner wall is ensured.
The utility model discloses can further set up to: the three abutting surfaces are respectively a first abutting surface positioned at two radial sides and a second abutting surface positioned between the two first abutting surfaces, the two first abutting surfaces are symmetrically arranged at two radial sides of the second abutting surface, and the radial length of the second abutting surface is greater than that of the first abutting surfaces.
Through further arrangement, three abutting surfaces are arranged, so that the lubricating effect and the stability are ensured, and meanwhile, the processing difficulty and the contact area between the roller and the pocket are reduced; and two first butt joint faces are symmetrically arranged at two sides of the second butt joint face, and the radial length of the second butt joint face is greater than that of the first butt joint faces, so that the stability of the bearing is further ensured.
The utility model discloses can further set up to: the radial both sides department of axial roof beam all is provided with the extension, the extension connect on first butt face, and be formed with the fore shaft between the extension of adjacent axial roof beam.
Through further setting up, the setting of extension forms the fore shaft on the one hand, forms spacingly to the roller, and on the other hand, the extension can form the effect of thickening to the first butt face that is located the radial both sides of pocket, guarantees the intensity of first butt face.
The utility model discloses can further set up to: the end part of the axial beam facing the outer diameter is provided with a notch, and one end of the axial beam facing the axle center is arranged in a solid mode.
Through further arrangement, the end part of the axial beam facing the outer diameter is provided with the notch, so that the weight of the retainer can be reduced on one hand, and on the other hand, the elasticity of the extending part close to the outer diameter can be increased by the notch, namely, the elasticity of the locking opening close to the outer diameter is enhanced, and the axial beam is convenient to disassemble and assemble.
