Abstract
The utility model provides a wheel hub bearing unit with three-convexity, which is composed of an outer flange plate, an inner ring, an inner flange plate, rollers, a rubber seal ring, holding frames, a dustproof cover and a knurling bolt, and is characterized in that the rollers with convexity are mounted in the holding frames, an inner ring sleeve is fixedly mounted on the outer circle of the one end of the inner flange plate; two rows of holding frames with rollers are respectively mounted between the inner and outer flange plates with convexity; the rubber seal ring is arranged between the inner ring and the end head of a roller channel of the inner flange plate, the rubber seal ring is arranged on the other ends of the outer flange plate and the inner flange plate; the dustproof cover is mounted on the outer circle of the inner ring, the center of the outer circle of the inner flange plate is provided with a hole, the knurling bolt is mounted in the hole; the convexities of the inner ring, the inner and outer flange plates and the rollers of the wheel hub bearing unit respectively are from 0.04 to 0.7 mm, three component are matched together so that the wheel hub bearing unit has high loading capacity, is abrasion resistant, has small vibration, low temperature rise and long service in operation process.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, specifically a kind of three cam hub bearing units of processing grinding.
Background technology
At present, the automobile hub bearing of various structures all is to be made of inside and outside flange, steel ball and the spare and accessory parts thereof of being with raceway groove, and this technology is day by day ripe, and is applied in widely on the various automobiles.But, yet exist to need improved place, little as the automobile hub bearing load capacity, rub resistance is poor, vibration is big, temperature rise is high, thus the life-span is held in the use that has reduced the hub spindle unit.
Summary of the invention
The utility model purpose is at the background technology deficiency, the three convexity automobile hub bearings that a kind of load carrying ability that provides is big, frictional vibration is little, temperature rise is low.
The technical solution of the utility model is achieved in that a kind of hub-bearing unit that is provided with three convexitys, it comprises outward flange dish, inner ring, inner flange, roller, rubber seal, retainer, cover of dust and knurled nut composition, it is characterized in that: when processing outward flange dish raceway, one end of outward flange dish roller surface is processed into convexity, also is processed into convexity with a end on the raceway of the corresponding inner flange of outward flange dish roller surface; In order to make cylindrical roller increase resistance to abrasion, on the cylindrical of cylindrical roller, be processed into convexity.
With cylindrical is that the roller of convexity is packed in the retainer, interior snare is fixed on the end cylindrical of inner flange; The two row retainers that roller is housed are installed in respectively between the inside and outside flange of band convexity; Rubber seal is located between the termination of inner ring and inner flange one raceway, and the other end of outward flange dish and inner flange is provided with rubber seal; On the big cylindrical of inner ring cover of dust is installed, the cylindrical center of inner flange is provided with the hole, and knurled nut is installed in the hole.
The hub-bearing unit that is provided with three convexitys described in the utility model, to have convexity be 0.004-0.007mm in processing on an end face of inside and outside flange raceway, also is processed into the convexity of 0.004-0.007mm on the roller cylindrical.
The beneficial effects of the utility model are, inside and outside flange and roller in the hub-bearing unit are respectively equipped with convexity, and the three cooperates that not only load carrying ability is big when making the product running, and rub resistance, vibration are little, and temperature rise simultaneously is low, thereby improves product life.
