Abstract
The utility model discloses a thrust bearing sealing ring with a circular ring shaped appearance, which comprises a rubber plate. The outside of the rubber plate is surrounded by a metal framework with a rectangular lateral surface, two slopes in opposite directions are disposed on the inside of the rubber plate, an upper slope is arranged on the top portion of the inside of the rubber plate, an included angle between the upper slope and a perpendicular line is 20 degrees, a lower slope is arranged at the bottom of the inside of the rubber plate, an included angle between the lower slope and the perpendicular line is 45 degrees, and the direction of a closed angle formed by the two slopes points to the inside of the rubber plate. The thrust bearing sealing ring has the advantages of simplestructure and convenient processing and manufacturing. By arranging the metal framework on an inner portion, the overall hardness of the sealing ring can be enhanced. Moreover, the metal framework can not be easily corroded. The circular arc structure at the bottom of the rubber plate of the sealing ring enables the sealing ring and a bearing to be hard to wear, thereby the fixing of the sealingring and the bearing is stabilized in terms of the bearing suffering comparatively large stress, and thrust can be greatly relieved. The sealing ring can not pop out, and simultaneously the bearing sealing ring can decrease the abrasion of the bearing and prolong the service life of the bearing.
Description
Technical field
The utility model relates to a kind of seal ring, particularly a kind of thrust-bearing seal ring.
Background technique
Existing thrust-bearing seal ring, discontinuity, working life is shorter.Thrust-bearing is stressed bigger, because bearing can produce a large amount of heats after running, heat can't distribute, the bearing cavity temperature is raise, pressure increases, and after the temperature and pressure of bearing cavity surpassed certain value, the gas that expands in the chamber just might eject seal ring, influence the working life of bearing, also might make the corollary equipment can't proper functioning
Summary of the invention
The purpose of this utility model is that provide for the deficiency that solves above-mentioned technology a kind of has thrust-bearing seal ring a plurality of sealing lips, hardness height, good sealing effect.
In order to achieve the above object, the thrust-bearing seal ring that the utility model is designed, profile is a ring, and it comprises offset plate, and it is the rectangular metal frame that has that the offset plate outer ring is established the side, the offset plate inboard is provided with two opposite slopes of direction, the offset plate inside top is provided with upslope, and upslope and vertical line angle are 20 °, and the bottom is provided with downslope, the angle of downslope and vertical line is 45 °, two wedge angle direction sensing offset plate inboards that the slope constitutes.Angle, offset plate bottom is circular-arc.The arc structure of seal ring offset plate bottom makes seal ring and bearing not easy to wear, and this has played the fixing of stabilized seal circle and bearing concerning stressed bigger bearing, can alleviate thrust greatly.Offset plate is mutually bonding with metal frame.
The resulting thrust-bearing seal 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, the arc structure of seal ring offset plate bottom makes seal ring and bearing not easy to wear, this has played the fixing of stabilized seal circle and bearing concerning stressed bigger bearing, can alleviate thrust greatly.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, upslope 2, metal frame 3, downslope 4, angle 5.
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 thrust-bearing seal ring of present embodiment, profile is a ring, and it comprises offset plate 1, and it is rectangular metal frame 3 that offset plate 1 outer ring is provided with the side, offset plate 1 inboard is provided with two opposite slopes of direction, offset plate 1 inside top is provided with upslope 2, and upslope 2 is 20 ° with the vertical line angle, and the bottom is provided with downslope 4, downslope 4 is 45 ° with the angle of vertical line, two wedge angle direction sensing offset plate inboards that the slope constitutes.Angle, offset plate 1 bottom 5 is circular-arc.The arc structure of seal ring offset plate bottom makes seal ring and bearing not easy to wear, and this has played the fixing of stabilized seal circle and bearing concerning stressed bigger bearing, can alleviate thrust greatly.Offset plate 1 is mutually bonding with metal frame 3, has guaranteed the soundness of offset plate and metal frame.
