Through further setting up, set up the retaining ring into the cross-section and be echelonment to set up the butt face of slope on the retaining ring, this the lower extreme of sealing lip that is can stretch down and do not contact with the step below the retaining ring, let the axial butt of sealing lip at the butt face afterwards, make the axial butt of sealing lip and butt face, reduce wearing and tearing on the basis of guaranteeing the sealed effect.
The present utility model may be further configured to: the retainer ring is including being located the lower step face that the butt face was kept away from roller one side department, the cross-section of skeleton is L shape setting and including the cover portion towards the radial extension of inner circle direction, clearance fit between the lower extreme of cover portion and the lower step face.
Through further setting up, set up the cover portion on the retaining ring to let the radial clearance fit that forms between cover portion its lower extreme and the lower step face, utilize the rigidity skeleton to form the shielding to the bearing inside, the great filth of effectual filtration avoids these filth to strike.
The present utility model may be further configured to: the framework comprises an axially extending mounting part, the framework is matched with the outer ring in an embedded manner through the outer diameter of the mounting part, and the sealing lip is arranged in the middle of the inner diameter of the mounting part and is matched with the covering part in a spaced manner.
Through further setting up, constitute its inlaying of dress cooperation with the outer lane through the installation department that extends by axial on the skeleton to with sealing lip sets up the middle part at installation department internal diameter, makes looks interval between sealing lip and the cover portion, provides certain space for sealing lip, avoids sealing lip and cover the condition emergence of mutual interference between the portion.
The present utility model may be further configured to: the inner ring is provided with oil holes communicated with the outside, a spacing part is arranged between the outer ring and the corresponding two rows of rollers, and the oil holes are aligned with the spacing part.
Through further setting up, set up the oil filler point on non-pivoted inner race to let the oil filler point aim at the interval portion department between two rows of rollers, lubricating oil can be quick after the injection lubricate the roller of both sides, can guarantee the smooth and easy of bearing operation.
