Detailed description of the invention
In order to be more fully understood that this utility model, below in conjunction with specific embodiment, this utility model is explained in detail.But, Obviously this utility model can be carried out different modification and remodeling and broader without departing from this utility model of appended claims Spirit and scope.Therefore, following example have exemplary and do not have conditional implication.
Embodiment:
A kind of rubber piston sealing ring, as shown in Figures 1 to 6, including seal and the skeleton that is connected with seal, skeleton Constituting rotary body with seal, be provided with the lip 1 of protrusion at the outer radial position of seal, lip 1 is provided with seal lip 2, seals Peripherally disposed after lip 2 have depression 3.
In the above-described embodiments, depression 3 is set to latticed.
In the above-described embodiments, the quantity of depression 3 is two rows.
In the above-described embodiments, the structure interlocked it is set between two row's depressions 3.
In the above-described embodiments, seal lip 2 is set to arc-shaped or corrugated or pointed shape or wedge shape.
In the above-described embodiments, skeleton is set to " Z " font.
In the above-described embodiments, skeleton is positioned close to the position of internal diameter of rubber piston sealing ring.
In the above-described embodiments, seal lip 2 matches with cylinder.
In the above-described embodiments, seal lip 2 and cylinder constitute the structure of interference fit.
In the above-described embodiments, the internal diameter of rubber piston sealing ring constitutes, with piston, the structure matched.
Rubber piston sealing ring of the present utility model, the lateral surface of its skeleton can be set to position supporting surface 4, its seal The bottom surface on base can be set to the static seal face 5 matched with piston, and its lip 1 can contact with cylinder inner wall.
Rubber piston sealing ring of the present utility model, belongs to rubber seal field, is particularly suitable for similar railway rolling stock brake Cylinder, the occasion that piston movement speed and reliability are required.Its seal can be set to rubber bodies, its can by rubber bodies and The rotary body that the Z-shaped skeleton being connected with rubber bodies is constituted.The sealing lip of prominent piston packing it is provided with at rubber bodies outer radial position Mouthfuls 2, seal lip 2 can be set to arc-shaped, seal lip 2 is the most peripherally disposed have that two rows interlock latticed recessed Cave 3.Z-shaped skeleton is near product internal diameter.The seal lip 2 of piston packing external diameter is formed dynamic close with cylinder inner wall 6 interference fit Envelope, piston packing internal diameter for location and fixes formation static seal with piston rod tight fit under the effect of skeleton.
Rubber piston sealing ring of the present utility model, its external diameter and the sealing of cylinder inner wall 6, play the rubber seal of sealing function Body, its lip 1 length is long, and during inflation, response speed is fast, the lip can designed flexibly with meet operating mode aerodynamic parameter requirement 1 structure.Longer long sealed lip 1, during inflation, pressurized can obtain rapidly and seal wider sealing surface, makes sealing reliable.Therefore Design lip 1 can be smaller with the cylinder wall magnitude of interference, can reduce friction during backhaul, prolongation product service life.Its sealing lip Mouthfuls 2 two rows circumferentially arranged below are interlocked netted depression 3, can avoid being affected by gravity lubricant grease and concentrate on bottom, make profit Lubricating oil fat the most circumferentially stores, and keeps the uniform lubrication to sealed lip 1.Significantly alleviate the abrasion of sealing lip.Gas Skeleton can realize the elastic conjunction of internal diameter and piston rod near piston packing internal diameter, and meets static seal requirement, prevents internal diameter from letting out Dew.Skeleton realizes the axial location of piston packing to outside, and supports the axial pressure that compressed air suffered by piston packing produces Power.Rubber bodies and Z-shaped skeleton are integral by sulfuration adhesion, and in the rubber bodies work of skeleton, relative deformation is little, reduces Impact on design lip 1, is beneficial to design satisfactory lip 1 structure faster.It is according to applying working condition, external diameter Seal lip 2 may be designed as wedge angle form, reduce friction corrugated form, increase sealed lip 1 motility wedge structure.
Although below various preferred implementations of the present utility model and feature are described, but without departing from this practicality On the premise of novel purpose and objective, those of ordinary skill in the art this utility model can be made many changes, supplement, Change and delete.The detailed description done above in association with specific embodiment of the utility model, is not to restriction of the present utility model. Every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, all still fall within this utility model skill The scope of art scheme.
