Abstract
The utility model discloses a seal ring for a conical ball bearing. The seal ring is in the shape of a circular ring, and comprises a rubber plate; a metallic framework with a right-angled section is looped in the rubber plate; part of one edge of the metallic framework extends into the rubber plate; pressure block rubber is separated from the rubber plate; an inner seal lip is arranged on the inner side of the rubber plate, comprises an upper turnover lip and a lower turnover lip, and has a transverse splayed section; the upper turnover lip and the pressure block rubber form a first arc chute; the lower turnover lip and the rubber plate form a second arc chute; and a protruded rib is arranged on the outer side of the rubber plate. The seal ring for the bearing has the advantages of simple structure and convenient processing and manufacture, improves the integral hardness of the seal ring, effectively prevents dust and liquid from invasion, can prevent grease from leakage, reduces the oil consumption, has no possibility of the bouncing-off of the seal ring, at the same time, reduces the abrasion of the bearing, and prolongs the service life of the bearing.
Description
Technical field
The utility model relates to a kind of seal ring, especially a kind of circular cone ball bearing seal ring.
Background technique
Existing circular cone ball bearing seal ring, all adopt and be installed in the seal groove of bearing outer ring both ends of the surface, and the sealing lip structure of seal ring is comparatively simple with the rubber seal of skeleton, through after the motion of bearing a period of time, sealing effect will variation, and various liquid, dust just can enter in the bearing, the phenomenon of grease futures occurs, grease in the bearing clings dust in air, make it in operation process, increase abrasive forces, weaken flexibility, thereby reduced the working life of bearing.
Summary of the invention
The purpose of this utility model is a kind of circular cone ball bearing seal ring that uses the interior sealing lip increase sealing effect of special construction that provides for the deficiency that solves above-mentioned technology.
In order to achieve the above object, the circular cone ball bearing seal ring that the utility model is designed, profile is a ring, it comprises offset plate, be equipped with the metal frame that the cross section is a right angle type in the offset plate, described right angle type is meant that two limits of metal frame are vertical, and intersection, two limits can be the right angle, also can be circular-arc, a limit part of metal frame stretches in the offset plate, and isolates a briquetting glue on offset plate, and it is flexible to increase fastness that metal frame stretches into the part of offset plate, the inboard of described offset plate is provided with interior sealing lip, should in sealing lip comprise turn over lip and under turn over lip, its sectional shape is horizontal Eight characters shape, turns over lip on described and briquetting glue forms the first arc groove, turn over lip and offset plate under described and form the second arc groove, the described offset plate outside is provided with prominent muscle.Be " downwards " direction wherein towards seal ring bottom surface direction, opposite direction be " on " direction, sealing lip can increase sealing effect, described briquetting glue and horizontal line angulation are preferably 15 °.Turning over lip and horizontal line angulation on described is 35 °, turns over lip under described and the horizontal line angulation is preferably 30 °.Described prominent muscle top is provided with the slope.Described slope and horizontal line angulation are preferably 80 °.Described offset plate can be mutually bonding with metal frame.
The resulting bearing sealed ring of the utility model, simple in structure, processing and fabricating is convenient.Establish metal frame by inside, can improve the integral hardness of seal ring, and metal frame is difficult for being corroded, and by the interior sealing lip of horizontal Eight characters shape and specific angular setting, can make the seal ring good sealing effect, effectively prevent the intrusion of dust, liquid, can stop leaking of grease again, reduce oil consumption, the phenomenon that seal ring ejects can not occur, reduce the wearing and tearing of bearing simultaneously, prolong the working life of bearing.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Among the figure: offset plate 1, metal frame 2, briquetting glue 3, on turn over lip 41, down turn over lip 42, the first arc groove 5, the second arc groove 6, prominent muscle 7, seal ring bottom surface 8, briquetting glue and horizontal line angulation α, on turn over lip and horizontal line angulation β, turn over lip and horizontal line angulation δ, slope and horizontal line angulation γ down.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, the described circular cone ball bearing of present embodiment seal ring, profile is a ring, it comprises offset plate 1, being equipped with the cross section in the offset plate 1 is the metal frame 2 of right angle type, described right angle type is meant that two limits of metal frame 2 are vertical, and intersection, two limits is circular-arc, and a limit part of metal frame 2 stretches in the offset plate 1, and isolates a briquetting glue 3 on offset plate, the inboard of offset plate 1 is provided with interior sealing lip, should in sealing lip comprise and turn over lip 41 and turn over lip 42 down that its sectional shape is horizontal Eight characters shape, on turn over lip 41 and the briquetting glue 3 formation first arc groove 5, under turn over lip 42 and form the second arc groove 6 with offset plate, offset plate 1 outside is provided with prominent muscle 7.Be " downwards " direction wherein towards seal ring bottom surface 8 directions, opposite direction be " on " direction, sealing lip can increase sealing effect, briquetting glue 3 is 15 ° with horizontal line angulation α, on to turn over lip 41 be 35 ° with horizontal line angulation β, under to turn over lip 42 be 30 ° with horizontal line angulation δ, described prominent muscle 7 tops are provided with the slope, described slope and horizontal line angulation γ are 80 °.
