Abstract
The utility model discloses a nylon retainer bearing, which comprises an inner ring, an outer ring, a dust cover and a plurality of steel balls. The axial length of the inner ring is longer than that of the outer ring. Grooves are arranged on the outer surface of one end of the inner ring and the inner surface of the outer ring. The steel balls are clamped in grooves between the inner ring and the outer ring, and nylon retainers are installed on one sides of the steel balls. Clamping grooves are respectively arranged on two sides of the grooves of the outer ring. The outer edge of the dust cover is provided with hemming which turns outwards. The dust cover is clamped in a clamping groove on the inner surface of the outer ring. The nylon retainer bearing can avoid abrasion of the steel balls, thereby effectively prolonging service life.
Description
Technical field
The utility model relates to a kind of nylon cages bearing.
Background technique
The life-span of rolling bearing is with the revolution hour number of the work under certain rotating speed (or with) definition: this life-span with interior bearing, preliminary fatigue damage (peel off or damaged) should take place on its any race ring or rolling element.Yet no matter in laboratory test or in actual use, all can significantly see, the identical bearing of the outward appearance under same operating conditions, differ widely actual life.The bearing " life-span " that also has several different definition in addition; One of them promptly so-called " operating life "; It representes that be not to be by due to the fatigue usually, but to be caused by reasons such as wearing and tearing, burn into bad seals by wearing and tearing, damage accessible actual life to a certain bearing damaging before.There is the influence that receives supporting frame working life of bearing in the existing technology.
The model utility content
The utility model provides a kind of nylon material retainer, can avoid steel ball wearing and tearing, effectively prolonged working life.
The utility model technical solution problem provides following scheme:
A kind of nylon cages bearing comprises inner ring, outer ring, dust cover and several steel balls, and the axial length of said inner ring is longer than the axial length of outer ring; The one end outer surface of said inner ring and the internal surface of outer ring are provided with groove; Said steel ball is fastened in the groove between the inside and outside circle, and said steel ball one side is equipped with nylon cages, and the groove both sides of said outer ring are established draw-in groove respectively; The outward edge of said dust cover is provided with the crimping of outward flanging, and said dust cover is fastened in the draw-in groove of inner surface.
The surface of said outer ring is provided with groove, and the ground roll extrusion of said groove has decorative pattern.
The utility model adopts the retainer of nylon material, and the retainer of nylon material can effectively prevent the friction of steel ball between Internal and external cycle, improved between the bearing enclose by hot temperature.
