Utility model content
The purpose of the utility model is to provide be equipped with sealing ring mounting groove alloy steel loop key, with solve it is above-mentioned at least
One technical problem.
The technical issues of the utility model is solved can be realized using following technical scheme:
Alloy steel loop key equipped with sealing ring mounting groove, the ring bodies for being equipped with opening including one, which is characterized in that the ring
The inner wall of shape body is equipped with an inner groovy, and the side wall of the inner groovy is equipped with multiple recess, and the recess is the two of the inner groovy
Mal-distribution on side wall, the inner groovy are embedded in inner seal ring, and the width of the inner seal ring is the indent groove width
1.1-1.2 times；
The outer wall of the ring bodies is equipped with external groove, and the slot bottom of the external groove is equipped with multiple protrusions, in the external groove
It is arranged exterior seal ring.
The utility model opens up mounting groove of the groove as sealing ring in the inner and outer wall of ring key respectively, and is arranged with close
Seal is effectively limited by the decrement of sealing ring, is avoided ring key from sliding and is reduced its vibration, and noise is reduced.If
The inner groovy set in inner wall is equipped with asymmetrically distributed recess on side wall, and the width of inner seal ring is slightly larger than the width of inner groovy
Degree, makes sealing ring combine closely with recess, to be stuck in inner groovy by the elasticity of pressure and sealing ring itself；Setting is outside
The external groove of wall can directly utilize the elasticity of sealing ring, be stuck in it in external groove, while can also play tightening ring key, anti-anti-avulsion
The protrusion of the effect fallen, external groove bottom can prevent sealing ring from rotating.
The internal diameter of the exterior seal ring is not more than the outer diameter of the ring bodies, the internal diameter of the exterior seal ring and the ring-type
The difference of the outer diameter of body is not more than 5mm.Ensure that sealing ring and ring key contacts are close enough.
The outer diameter of the inner seal ring is not less than the internal diameter of the ring bodies, the outer diameter of the inner seal ring and the ring-type
The difference of the internal diameter of body is not more than 5mm.Ensure that sealing ring and ring key contacts are close enough.
The inner seal ring and exterior seal ring are sealing rings made of rubber material, preferably made of hydrogenated nitrile-butadiene rubber
Sealing ring.Hydrogenated nitrile-butadiene rubber has splendid anticorrosive, tear-proof and incompressible deformation characteristic, and has good wear resistence
And heat resistance, the environment suitable for generator.
The inner surface of the outer surface of the exterior seal ring and the inner seal ring is equipped with densely arranged round salient point.Increase
The coefficient of friction on sealing ring surface prevents ring key from sliding.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model inner groovy and inner seal ring；
Fig. 3 is the structural schematic diagram of the utility model external groove and exterior seal ring.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, the alloy steel loop key equipped with sealing ring mounting groove, the ring bodies 1 for being equipped with opening including one,
The inner wall of ring bodies 1 is equipped with an inner groovy 2, and the side wall of inner groovy 2 is equipped with multiple recess 21, and recess 21 is in the two sides of inner groovy 2
Mal-distribution on wall, inner groovy 2 are embedded in inner seal ring 22, and the width of inner seal ring 22 is the 1.1-1.2 of 2 width of inner groovy
Times；The outer wall of ring bodies 1 is equipped with external groove 3, and the slot bottom of external groove 3 is equipped with multiple raised 31, is arranged exterior seal ring in external groove 3
32。
The utility model opens up mounting groove of the groove as sealing ring in the inner and outer wall of ring key respectively, and is arranged with close
Seal is effectively limited by the decrement of sealing ring, is avoided ring key from sliding and is reduced its vibration, and noise is reduced.If
The inner groovy 2 set in inner wall is equipped with asymmetrically distributed recess 21 on side wall, and the width of inner seal ring 22 is slightly larger than inner groovy 2
Width, so that sealing ring is combined closely with recess by the elasticity of pressure and sealing ring itself, to be stuck in inner groovy；Setting
The elasticity of sealing ring can be directly utilized in the external groove 3 of outer wall, is stuck in it in external groove 3, while tightening ring key can also be played,
The effect to fall off is prevented, the protrusion 31 of 3 bottom of external groove can prevent sealing ring from rotating.
The internal diameter of exterior seal ring 32 is not more than the outer diameter of ring bodies 1, the outer diameter of the internal diameter of exterior seal ring 32 and ring bodies 1 it
