Abstract
The utility model discloses a novel high-speed outer sealing ring. The novel high-speed outer sealing ring comprises a framework and a sealing rubber body, wherein the framework is arranged in the sealing rubber body; a shaft hole is formed in the sealing rubber body; n (n is more than 1) ring grooves are formed in the outer edge of the sealing rubber body; an oil separation lip body is arranged on the inner edge of the sealing rubber body; and the ring grooves are in a corrugated structure. The novel high-speed outer sealing ring is simple in structure, low in manufacturing cost, good in sealing performance and convenient to mount, is favorable for popularization and application.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of new structure high speed outer seal ring.
Background technique
The seal ring of selling on the market now, the overall structure of seal ring are annular, when mounted, elastic space is little, inconvenience is installed, and the sealing effect of seal ring is not fine, the axle system that seal ring seals easily enters dust, and this has a strong impact on sealing and the working life of power seal ring.In order to overcome the existing shortcoming of above-mentioned seal ring structure, artificers are making great efforts to improve innovation, so that better product to be provided to society.
Summary of the invention
The present invention has overcome the existing installation inconvenience of above-mentioned seal ring, and sealing effect is bad, and axle system easily enters dust, the shortcomings such as working life is short provide a kind of simple in structure, and are easy for installation, prevent that dust from entering axle system, retainer shaft system cleaning, the new structure high speed outer seal ring of long service life.
Foregoing of the present invention is mainly as follows by following scheme: a kind of new structure high speed outer seal ring, comprise skeleton and caulking gum body, skeleton is arranged in the caulking gum body, be provided with axis hole on the caulking gum body, be provided with annular groove on the outward edge of caulking gum body, be provided with a minute oily lip body on the inward flange of caulking gum body;
As preferably, the annular groove that arranges on the outward edge of the caulking gum body of new structure high speed outer seal ring is n (n＞1);
As preferably, be wave structure between the annular groove that arranges on the outward edge of the caulking gum body of new structure high speed outer seal ring and the annular groove.
By above narration: the present invention has advantage: 1, the setting of annular groove on the new structure high speed outer seal ring outward edge, annular groove is n (n＞1), be wave structure between annular groove and the annular groove, strengthened the pressurized elastic space of seal ring, sealing contact surface is long-pending to be increased, and is convenient to the installation of seal ring; 2, the setting of annular groove, the lubricant oil of axle system enters annular groove on the seal ring, and lubricant oil viscosity has strengthened the resistance of the movement of seal ring, and then has strengthened the sealability of seal ring; 3, the setting that divides oily lip body can make the oil that passes the seal ring axis hole be coated in uniformly the surface of axle, improves the overall operation stationarity of axle system; 4, the setting that divides oily lip body has prevented that effectively extraneous dust from entering axle system, keeps clean axle; 5, the utility model is simple in structure, and is cheap for manufacturing cost, and good seal performance is easy for installation, is conducive to apply.

Embodiment
Below in conjunction with embodiment, and in conjunction with schematic diagram, technical solution of the present invention is further described in detail.
As shown in Figure 1, a kind of new structure high speed outer seal ring comprises skeleton 1 and caulking gum body 2.Caulking gum body 2 is formed bodies of seal ring.Skeleton 1 is arranged in the caulking gum body 2, and skeleton 1 is the support of seal ring, prevents seal ring in the situation that pressurized is out of shape, and improves the working life of seal ring.Be provided with axis hole 3 on the caulking gum body 2.The setting of axis hole 3, the axle of being convenient to required sealing passes, and seal ring is limited on the axle.Be provided with annular groove 4 on the outward edge of caulking gum body 2.The annular groove 4 that arranges on the outward edge of caulking gum body 2 is wave structure for n (n＞1) between annular groove and the annular groove.Annular groove 4 is the setting of n (n＞1), and the setting that is wave structure between annular groove and the annular groove, has strengthened the pressurized elastic space of seal ring, and sealing contact surface is long-pending to be increased, and is convenient to the installation of seal ring.The setting of annular groove 4, the lubricant oil of axle system enters annular groove on the seal ring, and lubricant oil viscosity has strengthened the resistance of the movement of seal ring, and then has strengthened the sealability of seal ring.Be provided with a minute oily lip body 5 on the inward flange of caulking gum body 2.The setting that divides oily lip body 5 can make the oil that passes the seal ring axis hole be coated in uniformly the surface of axle, improves the overall operation stationarity of axle system.The setting that divides oily lip body 5 has prevented that effectively extraneous dust from entering axle system, keeps clean axle.
The utility model is simple in structure, and is cheap for manufacturing cost, and good seal performance is easy for installation, is conducive to apply.
