Abstract
A rolling deep groove ball bearing includes a bearing outer ring (1), a bearing inner ring (2), a plurality of large rolling balls (3) and special-shaped rollers (4), where the large rolling balls (3) and special-shaped rollers (4) are arranged between the bearing inner ring (1) and the bearing outer ring (2), and the large rolling balls (3) and the special-shaped rollers (4) are arranged at intervals. For the rolling deep groove ball bearing, the rolling balls (3) and the bearing raceway realize the pure rolling, where high linear velocity is subjected; the bearing capacity is large; the noise is low; the reliability is high and the service life is long. The deep groove ball bearing has no gap for installing balls and is simply assembled.
Claims4
A rolling ball bearing, comprising a bearing outer ring, a bearing inner ring, a plurality of rolling balls and special-shaped rollers, the rolling balls and special-shaped rollers are arranged between the bearing inner ring and the bearing outer ring, wherein the rolling balls and special-shaped rollers are arranged at intervals;
- a groove is provided in middle of the special-shaped rollers;
- a numerical value of a total gap s between the rolling balls and the special-shaped rollers is 0.03 mm<s<e, wherein e is a groove depth of the special-shaped rollers;
- a relationship between a diameter da of the special-shaped rollers and a distance h between the inner ring and the outer ring is h-da=0.005-0.2 mm, wherein h is (D2-d2)/2, D2 is an inner diameter of the outer ring, and d2 is an outer diameter of the inner ring.
