Description
Technical field:
The utility model relates to technical field of bearings, more specifically to a kind of double-row angular contact bal bearing.
Background technique:
The structural type of the dust cover of existing double-row angular contact bal bearing has a variety of, and its deficiency is, the installation of a lot of dust cover is very inconvenient, has produced cumbersome simultaneously, also there is the dissatisfactory problem of sealing.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of double-row angular contact bal bearing of one-side band dust cover, and it produces easily, easy for installation, good seal performance.
Technology solution of the present utility model is as follows:
The double-row angular contact bal bearing of one-side band dust cover, comprise inner ring, outer ring, first steel ball, first retainer, second steel ball and the second retainer, first steel ball sleeve is on the first retainer, first steel ball and the first retainer are clamped between inner ring and the raceway groove of outer ring, second steel ball and the second retainer are clamped between inner ring and the raceway groove of outer ring, upper shed place between inner ring and outer ring is provided with dust cover, dust cover is bonded together by stainless steel insert and rubber seal and forms, the cross section of stainless steel insert has lower horizontal segment, the outside of lower horizontal segment is extended with ring-type trip, ring-type trip is upwards extended with vertical section, the inner side of lower horizontal segment is extended with oblique section successively, upper horizontal segment and oblique compressing tablet section, rubber seal is bonded in the bottom of rust Steel Skeleton, rubber seal forms and is no less than two lips, uppermost that lip is placed in the bottom of oblique compressing tablet section,
Lip elasticity is pressed on the outer wall of inner ring, and ring-type trip is fastened in ring-type draw-in groove, and ring-type draw-in groove is positioned on the inwall of outer ring, and the ring-type draw-in groove of outer ring is positioned at step place, outer ring, and rubber seal is pressed on the step of outer ring.
Angles are spent for described oblique section horizontal by 30 to 60.
The beneficial effects of the utility model are:
It produces easily, easy for installation, good seal performance.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged view at A place in Fig. 1.
In figure: 1, inner ring; 2, outer ring; 3, the first steel ball; 4, the first retainer; 5, the second steel ball; 6, the second retainer; 7, dust cover.
Embodiment:
Embodiment: see Fig. 1, shown in 2, the double-row angular contact bal bearing of one-side band dust cover, comprise inner ring 1, outer ring 2, first steel ball 3, first retainer 4, second steel ball 5 and the second retainer 6, first steel ball 3 is enclosed within the first retainer 4, first steel ball 3 and the first retainer 6 are clamped between inner ring 1 and the raceway groove of outer ring, second steel ball 5 and the second retainer 6 are clamped between the raceway groove of inner ring 1 and outer ring 2, upper shed place between inner ring 1 and outer ring 2 is provided with dust cover 7, dust cover 7 is bonded together by stainless steel insert 71 and rubber seal 72 and forms, the cross section of stainless steel insert 71 has lower horizontal segment 711, the outside of lower horizontal segment 711 is extended with ring-type trip 712, ring-type trip 712 is upwards extended with vertical section 713, the inner side of lower horizontal segment 71 is extended with oblique section 714 successively, upper horizontal segment 715 and oblique compressing tablet section 716, rubber seal 72 is bonded in the bottom of rust Steel Skeleton 71, rubber seal 72 forms and is no less than two lips 721, uppermost that lip 721 is placed in the bottom of oblique compressing tablet section 716,
Lip 721 elasticity is pressed on the outer wall of inner ring 1, and ring-type trip 712 is fastened in ring-type draw-in groove 2a, and ring-type draw-in groove 2a is positioned on the inwall of outer ring 2, and the ring-type draw-in groove 2a of outer ring 2 is positioned at step 2b place, outer ring, and rubber seal 72 is pressed on the step 2b of outer ring.
Angles are spent for described oblique section 714 horizontal by 30 to 60.
Working principle: the ring-type trip 712 of stainless steel insert 71 is fastened on after on ring-type draw-in groove 2a, and oblique compressing tablet section 716 just creates elastic pressure to lip 721, and this elastic pressure makes lip 721 tightly be pressed on the outer wall of inner ring 1.Stainless steel insert 71 can disposable impact briquetting, so produce than being easier to, during installation, ring-type trip 712 is fastened on ring-type draw-in groove 2a, so install very convenient, while its good seal performance, good dust-proof effect can be played.
