Abstract
The utility model provides a bearing with a retaining frame with an oil-sealing function. The bearing comprises an inner ring, an outer ring, a rolling ball, the retaining frame and an upper oil seal, wherein the rolling ball and the retaining frame are clamped between the outer ring and the inner ring, the upper oil seal is arranged between the outer ring and the inner ring, the retaining frame is provided with an extension part coming out of the lower surface of the outer ring, an annular lapping edge opposite to the outer ring and an annular bulge opposite to the inner ring are formed on the extension part, a seal ring slot is formed in the inner ring and a rubber seal ring is placed in the seal ring slot; the annular lapping edge is close to and pressed on the lower surface of the outer ring and the annular bulge is pressed on the rubber seal ring. The retaining frame has the oil-sealing function and can seal bearing lubricating grease between the inner ring and the outer ring of the bearing.
Description
Technical field:
The utility model relates to technical field of bearings, has the bearing of oil sealing function more specifically to a kind of retainer.
Background technique:
The retainer of existing bearing is placed between the outer ring and inner ring of bearing, does not have the function of oil sealing.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of bearing of retainer tool oil sealing function is provided, and its retainer has the function of oil sealing, the bearing lubrication grease between energy stuffing box bearing inner ring and outer ring.
Technology solution of the present utility model is as follows:
The bearing of retainer tool oil sealing function, comprise inner ring, outer ring, ball, retainer and upper oil sealing, ball and retainer are clamped between outer ring and inner ring, between outer ring and inner ring, be provided with oil sealing, retainer has the extension part that exposes outer ring lower surface, on extension part, form facing to the ring-type scrap (bridge) of outer ring with facing to the annular projection of inner ring, form seal groove on inner ring, rubber seal is placed in sealing ring recess;
Ring-type scrap (bridge) is close on the lower surface that is pressed against outer ring, and annular projection is pressed against in rubber seal.
The lower surface of described inner ring is lower than the lower surface of outer ring, and the height of inner ring is greater than the height of outer ring.
The beneficial effects of the utility model are:
Its retainer has the function of oil sealing, the bearing lubrication grease between energy stuffing box bearing inner ring and outer ring.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
In figure: 1, inner ring; 1a, seal groove; 2, outer ring; 3, ball; 4, retainer; 41, extension part; 41a, ring-type scrap (bridge); 41b, annular projection; 5, upper oil sealing; 6, rubber seal.
Embodiment:
Embodiment: as shown in Figure 1, the bearing of retainer tool oil sealing function, comprise inner ring 1, outer ring 2, ball 3, retainer 4 and upper oil sealing 5, ball 3 and retainer 4 are clamped between outer ring 2 and inner ring 1, between outer ring 2 and inner ring 1, be provided with oil sealing 5, retainer 4 has the extension part 41 that exposes outer ring 2 lower surfaces, on extension part 41, form facing to the ring-type scrap (bridge) 41a of outer ring 2 with facing to the annular projection 41b of inner ring 1, on inner ring 1, form seal groove 1a, rubber seal 6 is placed in sealing ring recess 1a;
Ring-type scrap (bridge) 41a is close on the lower surface that is pressed against outer ring 2, and annular projection 41b is pressed against in rubber seal 6.
The lower surface of described inner ring 1 is lower than the lower surface of outer ring 2, and the height of inner ring 1 is greater than the height of outer ring 2.
Working principle: in prior art, retainer does not generally have the function of oil sealing, the utility model adopts retainer 4 to have the extension part 41 that exposes outer ring 2 lower surfaces, on extension part 41, form facing to the ring-type scrap (bridge) 41a of outer ring 2 with facing to the annular projection 41b of inner ring 1, on inner ring 1, form seal groove 1a, rubber seal 6 is placed in sealing ring recess 1a; Ring-type scrap (bridge) 41a is close on the lower surface that is pressed against outer ring 2, and annular projection 41b is pressed against in rubber seal 6.Rubber seal 6, ring-type scrap (bridge) 41a and annular projection 41b are the equal of just that the lower oil sealing of bearing is the same like this, so the utility model retainer has the function of oil sealing, can stuffing box bearing inner ring and outer ring between bearing lubrication grease.
