Abstract
The utility model relates to a novel cylindrical roller bearing which comprises an outer ring, an inner ring, rollers and a holding rack, wherein the holding rack is arranged between the outer ring and the inner ring; the rollers are arranged in the holding rack; a retaining ring is arranged on the side wall of the inner ring; and a stopping groove is formed in the outer diameter of the outer ring. The novel cylindrical roller bearing has the advantages that the structure is simple, the service life is long, concentrated edge stress does not happen frequently, early fatigue is avoided, and the bearing precision is improved.
Description
Technical field
The utility model relates to a kind of novel roller bearing.
Background technique
Traditional cylindrical roller bearing rotation precision and life-span are difficult to the well-known bearing enterprise in the world to matching in excellence or beauty, and produce edge stress concentration phenomenon during bearing working at raceway two ends, and early fatigue appears in raceway two ends, reduces bearing life, has a strong impact on bearing accuracy.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of and increase the service life, reduce the novel roller bearing that stress is concentrated.
The utility model solves the technological scheme that its technical problem adopts: a kind of novel roller bearing, there is outer ring, inner ring and roller and retainer, between described outer ring and inner ring, be provided with retainer, roller is arranged in retainer, on the sidewall of inner ring, be provided with back-up ring, on the external diameter of outer ring, offer locking groove.
Further, on the inwall of retainer described in the utility model, offer oilhole.
Further, the quantity of roller described in the utility model is 12-15.
The beneficial effects of the utility model are: the utility model is simple in structure, use life long, are not prone to edge stress concentration phenomenon, can not produce early fatigue, improve the precision of bearing.
