Abstract
A built-in spiral spring framework oil seal is a circular-ring rubber product and is provided with a circular-ring bottom ring, a circular-ring framework is arranged in the circular-ring bottom ring, the inner circumference of the bottom ring is connected with a circular-ring edge ring through a circular-ring kidney portion, a circular-ring sealing lip is arranged on the inner side of the edge ring, and a circular-ring spiral spring ring is arranged in the edge ring. The spiral spring is used as the framework to be placed in the circumferential rubber body of the edge ring, when the product is vulcanized, the periphery of the spiral spring framework can be wrapped by rubber materials, and when the seal is used, the spiral spring cannot fall off, and the spiral spring cannot be corroded and damaged by media.
Description
Technical field
The utility model relates to the spiral spring frame of a kind of oil sealing, particularly a kind of oil sealing.
Background technique
In machinery, the running shaft of some equipment is to stretch out in transmission case or work box, reveal in order to prevent lubricant oil or working solution in transmission case or work box, also in the intrusion transmission cases such as extraneous silt, dust, aqueous vapor or work box, between running shaft and transmission case, there is the oil sealing of sealing use in order to prevent.
Oil sealing is the rubber product of ring, oil sealing has the ring bottom part ring with ring skeleton, the inner circumference of bottom part ring is connected with ring cutting edge ring with the waist of ring, there is annular seal lip the inner side of cutting edge ring, there is ring spring groove in the outside of cutting edge ring, the useful straight line helical spring two ends ring helical spring ring forming that connects together in spring groove.
In prior art, helical spring ring is independent parts of composition oil sealing, and when assembling, helical spring ring is to be embedded in the ring spring groove in cutting edge ring outside.This oil sealing is because helical spring is to be embedded in the ring spring groove in cutting edge ring outside, between helical spring and rubber material, be not directly connected, when use, the helical spring being embedded in ring spring groove easily comes off in spring groove, be embedded in helical spring in ring spring groove in the time touching mordant sealing medium, easily damaged by dielectric corrosion.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and proposing a kind of helical spring quilt can not be from the built-in spiral spring frame oil sealing that comes off, can not be damaged by dielectric corrosion.
The utility model is realized with the following method.
Built-in spiral spring frame oil sealing is the rubber product of ring, built-in spiral spring frame oil sealing has ring bottom part ring, in ring bottom part ring, there is ring skeleton, the inner circumference of bottom part ring is connected with ring cutting edge ring with ring waist, there is annular seal lip the inner side of cutting edge ring, has ring helical spring ring in cutting edge ring.
Helical spring of the present utility model be as skeleton in cutting edge ring circumferential rubber body, in product when sulfuration,, sizing material can be wrapped in spiral spring frame around.When use, helical spring can not come off, can not be damaged by dielectric corrosion.
Below in conjunction with accompanying drawing, the utility model is further described.
Brief description of the drawings
Fig. 1 cuts open schematic diagram according to the master of a kind of built-in spiral spring frame oil sealing of scheme of the invention proposition of the present utility model depending on office;
Fig. 2 is that schematic diagram cuts open in the office of overlooking of Fig. 1.
Embodiment
In Fig. 1, Fig. 2, the rubber product 1 that built-in spiral spring frame oil sealing is ring, built-in spiral spring frame oil sealing has ring bottom part ring 2, in ring bottom part ring, there is ring skeleton 3, the inner circumference of bottom part ring is connected with ring cutting edge ring 5 with ring waist 4, there is annular seal lip 6 inner side of cutting edge ring, has ring helical spring ring 7 in cutting edge ring.
Claims (1)
1. a built-in spiral spring frame oil sealing, it is the rubber product of ring, built-in spiral spring frame oil sealing has ring bottom part ring, in ring bottom part ring, there is ring skeleton, the inner circumference of bottom part ring is connected with ring cutting edge ring with ring waist, there is annular seal lip the inner side of cutting edge ring, it is characterized in that: in cutting edge ring, have ring helical spring ring.
