Abstract
A seal structure comprises a bowl shaped seal made of a rubber, top shaped rotary folds arranged on the bowl shaped seal, wherein a small mouth end of the bowl shaped seal is sleeved and fixed on a rotation axle, a large mouth end of the bowl shaped seal is fixed on a shell; the small mouth port of the bowl shaped seal is fixed on the rotation axle by an annular anchor ear; the large mouth end of the bowl shaped seal is fixed on the shell by an annular large cushion ring and a screw; the large mouth port of the bowl shaped seal is provided with a fold umbrella. The structure is simple, the function is practical, the seal structure conquers the defects in the rotation seal technical field that: the structure is complicated, the parts process difficulty is large and the area is single and is more suitable for the dust-proof, water-proof, small-pressure small-angle rotation transmission device and the sealing effect is good. The seal structure is used for sealing an energy storage axle, a switchable brake and an indication axle of a power circuit breaker.
Description
Technical field
The utility model relates to a kind of sealing configuration.
Background technique
Motive sealing at present is the sealing between relative movement part in the machinery (or equipment), and motive sealing is divided into two types of reciprocating type motive sealing and rotary motive sealings, and rotary motive sealing has: the contact-type motive sealing that movement parts and static element directly contact; Both are the directly contactless motive sealing of contact not; The special nature that utilization is added on the seal clearance inner fluid reaches the semifluid motive sealing of sealing.The semifluid motive sealing has magnet fluid sealing.The machine and equipment that has must positive confinement, and the permission small leakage that has is so should select or design the structural type of sealing according to operational condition such as character, temperature, pressure and the relative velocity of working medium and to the requirement of sealability etc. for use.Small angle rotary seal occupies very big ratio (except wholecircle week in the rotating seal field; All the other can be the angle rotating seal); Wholecircle is socialized, and a lot of sealing means all exist drawback in the rotatable motive sealing; Defectives such as the single complex structure in sealing applications region takes up space big or the part processing degree-of-difficulty factor is big, the life-span is short, and wherein many structures all are not suitable for being applied in most angle rotary seal structures when deisgn product.
The model utility content
The utility model provides a kind of sealing configuration, and is simple in structure, is more suitable for being used for preventing dust, waterproof, small angle rotary actuator that pressure is little good sealing effect.
In order to solve the problems of the technologies described above; The utility model adopts following technological scheme: a kind of sealing configuration; Comprise the bowl type sealing that rubber is processed; The sealing of bowl type is provided with top in shape rotation fold, and the osculum end of bowl type sealing wears and is fixedly installed in the rotating shaft, and the big opening end of bowl type sealing is fixedly installed on the housing.
The osculum end of described bowl type sealing is fixedly installed in the rotating shaft through the anchor ear of annular.
The big opening end of described bowl type sealing is arranged on the housing through the big gasket ring and the screw of annular.
The big opening end of described bowl type sealing is provided with the fold umbrella.
The utility model is simple in structure, function is practical, and defective such as overcome complex structure in the rotary seal field, the part processing difficulty is big, the region is single is more suitable for being used for preventing dust, waterproof, small angle rotary actuator that pressure is little, good sealing effect.The utility model can be used for the sealing that energy storage axle, branch, combined floodgate and the indication axle of power circuit breaker etc. located.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Embodiment: like Fig. 1, shown in Figure 2; A kind of sealing configuration; Comprise the bowl type sealing 2 that rubber is processed; Bowl type sealing 2 is provided with top in shape rotation fold 7, and the osculum end of bowl type sealing 2 is fixedly installed in the rotating shaft 4 through the anchor ear 5 of annular, and the big opening end of bowl type sealing 2 is arranged on the housing 1 with screw through the big gasket ring 3 of annular.The big opening end of bowl type sealing 2 is provided with fold umbrella 6.
When mechanism was in free state, bowl type sealing 2 rotation folds were lax, and its two ends are anchored on respectively on rotating shaft 4 and the housing 1; The top rotation fold 7 of bowl type sealing 2 rotates with the axis by its texture when rotating shaft 4 rotation, and direction is launched or compression, and the bowl type fold umbrella 6 that seals 2 lower ends is compressed or stretches with the rotation of top fold simultaneously.No matter mechanism's rotating shaft is rotated to that direction small angle from free state, and the present invention is in sealing state in the time of can both being implemented in rotary course and maintenance and a certain state.By mechanical physical size, the space situations difference is selected the rubber bowl of different size for use, can more effectively save the space, accomplishes the exclusion seal effect of science.
Claims (4)
1. sealing configuration is characterized in that: comprise the bowl type sealing that rubber is processed, the sealing of bowl type is provided with top in shape rotation fold, and the osculum end of bowl type sealing wears and is fixedly installed in the rotating shaft, and the big opening end of bowl type sealing is fixedly installed on the housing.
2. sealing configuration according to claim 1 is characterized in that: the osculum end of described bowl type sealing is fixedly installed in the rotating shaft through the anchor ear of annular.
