Abstract

The utility model discloses a central adjusting roller bear special used maintaining rack, which is a whole structure, wherein a vertical oil hole (5) is uniformly equipped on the middle cross bar position of the maintaining rack, an oil dent (7) is uniformly equipped on a inner diameter of the maintaining rack, and the oil dent (7) is equipped on the bar between two pocket holes. The utility model is suitable for the central adjusting roller bear with a fixing middle blocking which adopts a whole maintaining rack. Compared with the original structure, the maintaining rack not only can provide room for the lengthening of the roller and increase the bearing ability of the bear, but also can increase the whole strength of the maintaining rack to avoid the collision and effect failure of the maintaining rack, increase oil holes and oil dents, solves the problem that the structure bear adopts the whole maintaining rack and the brought roller end face and blocking have poor lubrication, can ensure the fully lubrication of the bear blocking and the roller end face, decrease the bear heating and prolongs the using life of the bear.

Description

Separator Using For Core-aligning Roller Bearing

Technical field

The utility model belongs to a kind of retainer, relates generally to a kind of Separator Using For Core-aligning Roller Bearing.

Background technique

Band is selfaligning roller bearing structure such as Fig. 1 of centre rib, two halves retainer fixedly, it is combined by outer ring 1, roller 2, retainer 3 and inner ring 4, because its retainer 3 is combined intensity easy damage on the weak side by the two halves retainer, bearing capacity is low, and roller and rib sliding friction are big.To heavy with radial load, bear vibration is impacted serious occasion, its load carrying capacity deficiency for bearing shaft.

Summary of the invention

The purpose of this utility model provides a kind of Separator Using For Core-aligning Roller Bearing, in order to the narrow limitation that the selfaligning roller bearing that solves the band rib uses in the abominable occasion of operating mode, prolongs the working life of bearing.

The purpose of this utility model can adopt following technological scheme to realize: it is an integral cage, and the lintel place in the middle of the retainer is evenly equipped with radial direction oil hole, is evenly equipped with oil groove in the inner radius of retainer, and oil groove is on the beam between the two pocket holes.

The utility model is applicable to the fixedly selfaligning roller bearing of centre rib of band, adopt integral cage, can strengthen the intensity of retainer, roller can suitably extend simultaneously, can improve the fixedly intensity of the retainer of the selfaligning roller bearing of centre rib of band, improve bearing load carrying capacity, be applicable to that bearing is subjected to heavy duty, stressed complexity and the abominable occasion of operating mode such as impact shock load is arranged.This retainer is compared with original structure, can provide the space for the lengthening of roller, improve bearing load carrying capacity, can improve the bulk strength of retainer again, avoid the collision of retainer to lose efficacy, increase oilhole and oil groove, the roller end face that has brought when having solved this airframe bearing employing integral cage and the insufficient lubrication problem of rib, can guarantee the sufficient lubrication of bearing edge guard and roller end face, reduce bearing heating, prolong bearing working life.

Among the figure: 1, outer ring, 2, roller, 3, retainer, 4, inner ring, 5, oilhole, 6, the pocket hole, 7, oil groove, 8, rib and roller end face contacting point, h is the degree of depth of retainer oil groove, b is a pocket depth.

Embodiment

In conjunction with the accompanying drawings, specific embodiment of the utility model is described.

Shown in Fig. 2,3,4,5, the utility model retainer adopts overall structure, and roller pocket hole 6 is taken turns to bore in the retainer two sides, makes pocket hole 6 be distributed on the middle lintel of retainer both sides, to isolate roller.The lintel place is evenly equipped with radial direction oil hole 5 in the middle of retainer, oilhole 5 is a through hole, so that lubricant oil enters in the retainer, inner radius at retainer is evenly equipped with oil groove 7, oil groove 7 is on the beam between the two pocket holes, and lubricant oil can enter in the retainer from the oilhole among Fig. 2 and Fig. 35, enters rib shown in Figure 6 and roller end face contacting point 8 from oil groove 7 again, realize the sufficient lubrication at this position, reduce bearing heating.

Claims (1)

1, a kind of Separator Using For Core-aligning Roller Bearing is characterized in that: it is an overall structure, and the lintel place is evenly equipped with radial direction oil hole (5) in the middle of the retainer, is evenly equipped with oil groove (7) in the inner radius of retainer, and oil groove (7) is on the beam between the two pocket holes.
