Abstract
The utility model relates to a totally-sealed four-row tapered roller bearing, which belongs to the technical field of bearings. A row of rollers is arranged between a single-raceway outer ring and a double-raceway inner ring, double rows of rollers are arranged between a double-raceway outer ring and the double-raceway inner ring, the rollers are arranged in a retainer, an outer ring spacer is disposed between the single-raceway outer ring and the double-raceway outer ring, a side sealing component is disposed on the outer side of the bearing, a groove is arranged in the double-raceway inner ring, and an inner sealing component is embedded in the groove. The totally-sealed four-row tapered roller bearing has the advantages that elasticity and toughness of the inner sealing rubber component are excellent, so that the inner sealing rubber component can effectively replace an inner ring spacer to realize a sealing function, and gaps due to abrasion of end surfaces can be filled in time. Sealing property of the bearing is improved due to the totally-sealed structure, sufficient lubrication of the bearing is guaranteed, friction between a rolling body in the bearing and a raceway is reduced, working temperature is lowered, fatigue of the raceway of the bearing is decreased, and rotation precision and rotation speed of the bearing are guaranteed. In addition, backlashes are adjusted by the outer ring spacer, and the advantage that the ring spacer adjusts the backlashes is kept.
Description
Technical field
The utility model relates to a kind of all-sealed four-row tapered roller bearing, belongs to technical field of bearings.
Background technique
Four-row tapered roller bearing uses under operating conditions rugged environments such as mine, metallurgy and milling train usually; Four-row tapered roller bearing is for preventing extraneous foreign matter, and such as impurity, iron scale, cooling liquid etc., it is inner to get into bearing; Therefore the sealed type tapered roller bearing has appearred; At present, most of four row O-ring taper roller bearings mainly lean on sealed at both ends, middle spacer ring sealing and the adjusting play of adopting.Under the inner ring high speed rotating, can produce relative rotation between inner ring and cone spacer, cause lasso and spacer ring end wear and the slit occurs, influenced the bearing integral sealability, so this sealing structure effect and endurance are unsatisfactory.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of the utility model is to provide a kind of all-sealed four-row tapered roller bearing, and its no cone spacer and replace the cone spacer sealing with interior caulking gum assembly is improved the sealability of bearing.Thereby at utmost prevented the entering of extraneous foreign matter and leaking of lubricant grease, kept the superiority that spacer ring is regulated play simultaneously, guaranteed the function of use of bearing and the life-span of having improved bearing.
A kind of all-sealed four-row tapered roller bearing comprises single raceway outer ring, outer ring with double raceway, two raceway inner ring, roller, retainer, outer ring spacer, interior black box, side sealing assembly; Between single raceway outer ring and the two raceway inner ring is a row roller; Between outer ring with double raceway and the two raceway inner ring biserial roller is arranged; Roller is an outer ring spacer between single raceway outer ring and the outer ring with double raceway in retainer, and there is the side sealing assembly in the outside of bearing; Fluted between two raceway inner rings, interior black box is embedded in the groove.
The advantage of the utility model: interior caulking gum assembly elasticity and toughness are fine, can effectively replace the cone spacer sealing, in time fill up the slit that end wear occurs.This all-sealed structure has improved bearing seal property, has guaranteed the bearing sufficient lubrication, has reduced the friction of inner rolling element of bearing and raceway, has reduced operating temperature, delays bearing race fatigue, has guaranteed running accuracy and bearing rotating speed.Through outer ring spacer adjustment play, kept the advantage of spacer ring adjustment play.
