Abstract
The utility model discloses a universal sealing ring with an annular appearance, which comprises a rubber board, a rubber board outside ring is provided with a metal framework with a right-angle section, in other words, a right angle refers to the fact that two edges of the metal framework are perpendicular, intersection of the two edges can be a right angle also can be an arc shape, one right-angle edge of the metal framework is parallel to the bottom face of the sealing ring, the other right-angle edge contacts with a step end face on outer side of the rubber board, and two upwardly turned sealing lips are arranged inside the rubber board and used for enhancing sealing effect. The universal joint sealing ring has simple structure and convenient processing and fabrication. Through addition of the sealing lips and use of a most reasonable angle structure, the sealing ring has fine sealing effect, can effectively prevent invasion of dust and liquid, and also prevent leakage of grease, reduces grease consumption, simultaneously reduces wear of a universal joint, and prolongs service life of the universal joint.
Description
Technical field
The utility model relates to a kind of seal ring, especially a kind of universal joint seal ring.
Background technique
At present in the middle of the use of universal joint, in order to make spindle nose in the outer ring and ball in the middle of the operation of various work condition environments, can both keep good lubricating status, a seal ring need be set in the end of outer ring.In the technology, adopt one or two O RunddichtringO usually, but its sealing effect is often not satisfactory now.The sealing configuration of double-layer seal ring etc. has also appearred in market, and what also have establishes metal truss at the seal ring outer shroud and increase hardness, though improved some sealabilities, but still be difficult to reach simultaneously dustproof, waterproof, can stop the effect that grease leaks in the spindle nose again.
Summary of the invention
The purpose of this utility model is a kind of universal joint seal ring that uses the 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 universal joint seal ring that the utility model is designed, profile is a ring, it comprises offset plate, the offset plate outer ring is provided with the metal frame that the cross section is a right angle type, 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, right angle side of metal frame is concordant with the seal ring bottom surface, another right angle side contacts with the step end face in the offset plate outside, and the inboard of described offset plate is provided with two retrousse sealing lips, can increase sealing effect.In order to reach the most rational sealing effect, described step end face is provided with the slope.Through test of many times, preferably 55 ° and 70 ° of the angle of described two retrousse sealing lips and vertical line difference, the angle of described slope and vertical line is preferably 45 °.In order to increase fastness and sealing, can be that described offset plate is mutually bonding with metal frame.
The resulting universal joint seal ring of the utility model, simple in structure, processing and fabricating is convenient.By increasing sealing lip, and use angle with rational structure, in the use of universal joint, good sealing effect can effectively prevent the intrusion of dust, liquid, can stop leaking of grease again, reduce oil consumption, reduce the wearing and tearing of universal joint simultaneously, prolong the working life of universal joint.
Description of drawings
Fig. 1 is the utility model embodiment 1 a structural representation.
Among the figure: the angle δ of angle β, slope and the vertical line of angle α, lower lip and the vertical line of offset plate 1, metal frame 2, seal ring bottom surface 3, step end face 4, slope 5, sealing lip 6, upper lip and vertical line.
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 universal joint seal ring of present embodiment, profile is a ring, it comprises offset plate 1, offset plate 1 outer ring is provided with the metal frame 2 that the cross section is a 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, offset plate 1 is mutually bonding with metal frame 2,2 one right angle sides of metal frame are concordant with seal ring bottom surface 3, and another right angle side contacts with the step end face 4 in offset plate 1 outside, and the inboard of offset plate 1 is provided with two retrousse sealing lips 6, wherein is upper lip, following is lower lip, and the angle of upper lip and vertical line is that α is 55 °, and the angle β of lower lip and vertical line is 70 °, step end face 4 is provided with slope 5, and slope 5 is 45 ° with the angle δ of vertical line.
