Abstract
The utility model relates to a pulley bearing seal ring structure which is characterized in that a seal ring comprises a steel ring provided with a ringlike end surface and an outer ring, wherein rubber layers extending to the inner ring of the steel ring are pressed on the inner side surfaces of the ringlike end surface and the outer ring; and the included angle between the outer ring and the ringlike end surface is 87-88 degrees. The seal ring structure has the advantages that when in use, the outer side surface of the steel ring of the seal ring is led to face inwards to pressed between the inner ring and the outer ring of a pulley bearing, since the included angle between the outer ring and the ringlike end surface of the steel ring is 87-88 degrees, the position of the outer ring of the steel ring, close to the end surface, is higher and rightly embedded into a clamping groove in the inner wall of the outer ring of the bearing, while an elastic rubber layer is clung to the inner ring of the bearing so as to realize sealing the end surface of the bearing by the seal ring. Due to the adoption of the steel ring as a main body, the heat-resistant quality is improved, good sealing effect is ensured, without deformation easily.
Description
Technical field
The utility model relates to a kind of pulley bearings ring structure, particularly a kind ofly is difficult for that deformation, resistance to heat are good, the pulley bearings ring structure of good seal performance.
Background technique
Bearing sealed ring is installed between the end face of the inside and outside circle of bearing, is used to prevent that dust, foreign material etc. from entering in the rolling element.Traditional bearing sealed ring is that gum is made, and resistance to heat is poor, and yielding, wearing and tearing cause to come off.
The model utility content
The technical problems to be solved in the utility model provides and a kind ofly is difficult for that deformation, resistance to heat are good, the pulley bearings ring structure of good seal performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pulley bearings ring structure, it is characterized in that: described seal ring comprises that one has the steel ring of annular end face and outer ring, and the inner side surface in described annular end face and outer ring is suppressed with an elastic rubber layer that extends to steel ring inner ring place; The angle of described outer ring and annular end face is 87-88 °.
Advantage of the present utility model is: during use, with the steel ring outer side surface of seal ring inwardly, be pressed between the inside and outside circle of pulley bearings, because the outer ring of steel ring and the angle of annular end face are 87-88 °, the steel ring outer ring is higher near the end, just embed in the draw-in groove of bearing outer ring inwall, and elastic rubber layer is close to bearing inner race, realizes the sealing of seal ring bearing face.Owing to adopt steel ring as main body, improved resistance to heat, not yielding, guaranteed good sealing effect.
Description of drawings
Fig. 1 is the utility model pulley bearings ring structure schematic representation.
Fig. 2 is installed to schematic representation in the bearing for the utility model pulley bearings seal ring.
Embodiment
As shown in Figure 1, the utility model relates to a kind of pulley bearings seal ring, comprises a steel ring 1, and it has annular end face 1a and outer ring 1b, is suppressed with the rubber layer 2 that extends to steel ring inner ring place at the inner side surface of annular end face 1a and outer ring 1b.The outer ring 1b of steel ring 1 and the angle of annular end face 1a are 87-88 °, and best angle is 87.5 °.
During use, as shown in Figure 2, with steel ring 1 outer side surface of seal ring inwardly, be pressed between the inner ring 3, outer ring 4 of pulley bearings, because the outer ring 1b of steel ring and the angle of annular end face 1a are 87-88 °, steel ring outer ring 1b is higher near end face 1a place, just embeds in the draw-in groove of bearing outer ring 4 inwalls, and rubber layer 2 is close to bearing inner race 3, realizes the sealing of seal ring to bearing face.
