Assembly type split framework oil seal

Abstract

The invention discloses an assembly type split framework oil seal. The assembly type split framework oil seal comprises a sealing lip, a cap portion, a spring groove, a framework, a shoulder portion, bosses, grooves, a plug pin, a plug hole, a back portion, a waist portion and a dustproof lip which form a splitting integrative structure. The sealing lip is arranged outside the cap portion, the spring groove is arranged inside the cap portion, the dustproof lip is arranged outside the waist portion, bosses are arranged in the middle of the external periphery of the shoulder portion, each groove is arranged between two neighboring bosses, the back portion is connected in one with the shoulder portion, the bosses, the grooves, the waist portion, the dustproof lip, the cap portion, the sealing lip and the spring groove, the spring is independently arranged inside the spring groove, the shoulder portion is provided with the framework, the two ends of the split part of the shoulder portion are provided with the plug pin and the plug hole respectively. The assembly type split framework oil seal is convenient and rapid to install, the framework designed inside the shoulder portion greatly enhances the strength of the shoulder portion to guarantee the radial tight cooperation between the shoulder portion and the end cover of a splitting type device; the framework inside the shoulder portion is made of spring steel and accordingly guarantees no deformation during installation; the assembly type split framework oil seal is simple in structure, low in cost and good in adaptability, facilitates online replacement, effectively improves the working efficiency and saves time and the equipment maintenance cost.

Description

technical field [0001] The invention relates to a lubricating oil (grease) sealing device for a bearing box or a gear box used for a rotating shaft in mechanical equipment, in particular to an assembly type split skeleton oil seal. Background technique [0002] The seals of bearing boxes and gearboxes, which are usually used in the market where the shaft ends are difficult to disassemble, mainly use felt strip seals and labyrinth seals, or a combination of felt strip seals and labyrinth seals. These two sealing forms have a better sealing effect and a longer service life when the oil supply and return of the equipment are normal. However, when the oil supply and oil return system of the equipment fails or the artificial oil supply is excessive, there will be a large amount of leakage, and when starting and stopping, no matter whether the oil supply is normal or not, there will be leakage. [0003] For the above-mentioned sealing leakage situation, there is currently a lack ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the sealing problem under the failure of the existing labyrinth seal and felt strip seal, and provide a sealing lip, a crown, a spring groove, a skeleton, a shoulder, a boss, a groove, a latch, a socket, a back , waist, and dust-proof lip form a split type, and a spring is installed in the spring groove to apply a pre-tightening force to the sealing lip, which is easy to install and reliable in sealing.
