Description

A kind of high speed deep groove ball bearing

Technical field

The utility model relates to a kind of deep groove ball bearing more particularly to a kind of high speed deep groove ball bearings.

Background technique

Traditional deep groove ball bearing includes outer ring, inner ring, rolling element, nylon cages and dustproof cover, and nylon cages are Crown type frame is equipped with the groove with opening in one end face of nylon cages, and the width of opening is less than the diameter of rolling element, outer ring suit On the outside of inner ring, nylon cages are arranged between outer ring and inner ring, the opening on groove that rolling element passes through nylon cages It clamps in a groove, the nylon cages two sides between outer ring and inner ring is set in dustproof cover；It is recessed due to nylon cages Easily-deformable after injection moulding for installing the opening of rolling element on slot, nylon cages are uneven when deep groove ball bearing moves Surely, failure is especially prone to wear when running at high speed, to influence its service life.

Summary of the invention

For disadvantage mentioned above, the purpose of this utility model is to provide a kind of high speed deep-groove ball axis that can be improved service life It holds.

The technology contents of the utility model are a kind of high speed deep groove ball bearing, it is characterized in that it includes outer ring, inner ring, rolling Kinetoplast, nylon cages, end cap and dustproof cover；Nylon cages include foundation ring and several roller trestles, several roller trestles One end is uniformly arranged on foundation ring, and the end face of the other end of several roller trestles is equipped with a snap-in groove；Adjacent two roller A rolling element groove is formed between trestle, the width of the opening of rolling element groove and the diameter of rolling element are equal；End cap is annular, Inside and outside end cap be equipped with it is several to corresponding recess, two corresponding recesses form a card column on end cap, card column Quantity is equal with the quantity of roller trestle；Outer ring is sleeved on the outside of inner ring, and nylon cages are arranged between outer ring and inner ring, rolling Kinetoplast is arranged in the rolling element groove of nylon cages, and the open end of the rolling element groove of nylon cages is arranged in end cap, The card column of end cap snaps onto the snap-in groove of roller trestle；The nylon cages between outer ring and inner ring are arranged in dustproof cover Two sides.

The utility model compared with prior art possessed by advantage are as follows: the rolling element of the utility model is sealed by end cap In the rolling element groove of roller trestle, so that nylon cages are steady when deep groove ball bearing moves, especially in high speed Wear-out failure is not easy when operating, to improve its service life.
