Embodiment Construction

[0020] In order to make the purpose, advantages and features of the present invention clearer, an internal and external dustproof oil seal structure proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that: the drawings are all in a very simplified form and use inaccurate proportions, which are only used to facilitate and clearly illustrate the purpose of the embodiments of the present invention; secondly, the structures shown in the drawings are often actual structures part.

[0021] see figure 1 , this embodiment proposes an internal and external dustproof oil seal structure, the internal and external dustproof oil seal structure is a ring-shaped integrated structure, including: an outer skeleton, an inner skeleton, a main lip 3, a spring 4, an outer auxil...

Abstract

The invention discloses an inner and outer dustproof oil seal structure. The inner and outer dustproof oil seal structure is of an annular integrated structure, and comprises an outer framework, an inner framework, a main lip, a spring, an external auxiliary lip and an internal auxiliary lip; the internal auxiliary lip comprises a body and a first protruding portion; and the first protruding portion is obliquely raised on the body and faces the oil side. The main lip plays an oil sealing role, the external auxiliary lip plays a role in isolating external foreign matters, and the internal auxiliary lip plays a role in isolating internal foreign matters. Therefore, the problem of damage caused by contact of the main lip and impurities in the box body in the prior art is solved, and double dust prevention is realized on the oil seal structure. Meanwhile, the existing structure of the box body is kept unchanged to the maximum extent, the installation process is not changed, and the cost issaved. Furthermore, the inner and outer dustproof oil seal structure adopts a generalized design and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an internal and external dustproof oil seal structure. Background technique [0002] The oil seal is a mechanical element used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance), which isolates the parts that need to be lubricated from the output parts in the transmission parts. Do not let the lubricating oil leak. Seals for static seals and dynamic seals (general reciprocating motion) are called oil seals. Skeleton oil seal is a typical representative of oil seal, which is a double-lip (main lip, external auxiliary lip) oil seal with self-tightening spring fully covered by rubber. Used in gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles and other parts. [0003] In the automotive field, oil seals are used in a wide rang...
