The purpose of this utility model realizes by the following technical solutions:
A kind of band plummer block housing roller bearing units, comprises vertical shaft bearing, outer ring, inner ring and the ball between outer ring and inner ring and retainer, on one end circumference of described inner ring, jackscrew is set, and by jackscrew, inner ring is fixed on axle; Between described inner ring, outer ring, seal ring is set, is positioned at the outside of ball and retainer, the both sides end face setting of described outer ring is used for the back-up ring of sealing, is stuck on the excircle of inner ring, with outer ring Spielpassung; Described vertical shaft bearing two side ends face is provided with seam, and a side seam setting is embedded in the blind lid in seam, and a side seam setting is embedded in the through hole lid in seam, and the through hole of described through hole lid is installed with oil sealing.
As the improvement to technique scheme, described seal ring is made up of steel sheet skeleton and the nitrile rubber being coated on steel sheet skeleton.
As the improvement to technique scheme, on described vertical shaft bearing excircle, lubricating cup is set, the oil groove around outer ring circumference is set on outer ring, in oil groove, be provided with oilhole, lubricating cup, oil groove, oilhole communicate, and communicate with the cavity between outer ring and inner ring, realize lubricating ball and retainer.
As the improvement to technique scheme, on the circumference of described outer ring, stop pin is set, outer ring is fixedly connected with vertical shaft bearing, to prevent relatively rotating of outer ring.
As the improvement to technique scheme, the endoporus left and right sides of described vertical shaft bearing arranges the axial handling groove of circular arc, and so design, is convenient to installation and removal.
As the improvement to technique scheme, described outer ring, inner ring, blind lid, through hole cap surface are zinc-plated.
The utility model has the advantage of: band plummer block housing roller bearing units of the present utility model, its inner ring is fixedly connected on axle by jackscrew; Seal ring is set between Internal and external cycle, the both ends of the surface setting of outer ring be used for sealing back-up ring, the blind lid of bearing support arranged outside and through hole lid, can prevent that muddy water and dust from entering, good sealing effect, to avoid the corrosion to ball and retainer; Outer ring is provided with oil groove, and has oilhole to communicate with inner chamber, refuels very conveniently, and it is easily simple that maintenance becomes.
