Abstract
The utility model discloses an oil seal of a steering device which comprises a rubber body 1, a framework 2, a nylon support ring 4 and a spring ring 3, wherein the rubber body 1 is provided with an inner ring and an outer ring; the spring ring 3 is positioned at the upper part of the outer surface of the inner ring of the rubber body 1; the framework 2 comprises a horizontal part and a vertical part which extends into the outer ring of the rubber body 1; the nylon support ring 4 is positioned in a groove at the lower part of the inner surface of the inner ring of the rubber body 1; the horizontal part of the framework 2 extends towards the groove of the inner ring of the rubber body 1; and the lower surface of the nylon support ring 4 is placed on the upper surface of the part of the framework 2. By adopting the structure, the nylon support ring cannot be flushed out no matter how great the environmental pressure is, so that the oil seal can work normally to ensure good sealing and improve safety factor.
Description
Technical field
The utility model relates to a kind of commutator oil sealing.
Background technique
Existing commutator oil sealing is made up of rubber body 1, skeleton 2, nylon support ring 4 and spring ring 3, as shown in Figure 2, rubber body 1 has inner ring and outer ring, spring ring 3 is positioned at the outer surface top of rubber body 1 inner ring, nylon support ring 4 is arranged in the internal surface lower recess of rubber body 1 inner ring, skeleton 2 is made up of horizontal part and vertical component effect, and the vertical component effect of skeleton 2 puts in the outer ring of rubber body 1, and the lower surface of nylon support ring 4 is concordant with the lower surface of skeleton 2 horizontal parts.Because work under bad environment, pressure is very high, this just requires the anti-high pressure of commutator oil sealing energy, so need the nylon support ring, supports oil sealing when the commutator oil sealing is worked, be unlikely to make the distortion of commutator oil sealing waist, cause the leakage of oil of commutator oil sealing, if but pressure is too high, and the nylon support ring is given by high pressure easily and is swept away, the commutator oil sealing will leak, and commutator is malfunctioning.
The model utility content
Technical problem to be solved in the utility model is: a kind of commutator oil sealing is provided, and the nylon support ring came off when this kind commutator oil sealing can be avoided the work of commutator oil sealing, thereby guaranteed that sealing is intact, improved safety coefficient.
Solve this technical problem, the technical solution of the utility model is: a kind of commutator oil sealing, form by rubber body, skeleton, nylon support ring and spring ring, rubber body has inner ring and outer ring, spring ring is positioned at the outer surface top of rubber body inner ring, skeleton is made up of horizontal part and vertical component effect, the vertical component effect of skeleton puts in the outer ring of rubber body, the nylon support ring is arranged in rubber body inner ring internal surface lower recess, the horizontal part of described skeleton stretches out the groove of rubber body inner ring, and the lower surface of described nylon support ring places on the upper surface of skeleton horizontal part.
The vertical component effect of described skeleton is provided with a plurality of through holes.
A kind of commutator oil sealing of the utility model adopts such structure, and no matter external pressure has muchly, can guarantee that the nylon support ring is not rushed out, and oil sealing can be worked normally, guarantees that sealing is intact, has improved safety coefficient.
Description of drawings
Below in conjunction with accompanying drawing a kind of commutator oil sealing of the utility model is done explanation in further detail;
Fig. 1 is the structural representation of a kind of commutator oil sealing of the utility model;
Fig. 2 is the structural representation of prior art commutator oil sealing;
In Fig. 1, Fig. 2,1, rubber body; 2, skeleton; 3, spring ring; 4, nylon support ring.
Embodiment
As shown in Figure 1, a kind of commutator oil sealing, by rubber body 1, skeleton 2, nylon support ring 4 and spring ring 3 are formed, rubber body 1 has inner ring and outer ring, spring ring 3 is positioned at the outer surface top of rubber body 1 inner ring, nylon support ring 4 is arranged in rubber body 1 inner ring internal surface lower recess, skeleton 2 is made up of horizontal part and vertical component effect, the vertical component effect of skeleton 2 puts in the outer ring of rubber body 1, the vertical component effect of skeleton 2 has a plurality of through holes, make rubber body 1 better with engaging of skeleton, the horizontal part of skeleton 2 extends to the groove of rubber body 1 inner ring, and the lower surface of described nylon support ring 4 places on the upper surface of skeleton 2 horizontal parts.Such structure, no matter external pressure has muchly, can guarantee that the nylon support ring of commutator oil sealing is not rushed out, and oil sealing can be worked normally, guarantees that sealing is intact, has improved safety coefficient.
