Description

Technical Field

[0001] The utility model relates to the technical field of oil seals, in particular to a rubber seal used for automobile oil seals. Background Art

[0002] Oil seal is a common name for general seals. Simply put, it is a seal for lubricating oil. It is a mechanical component used to seal grease. It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. The seals used for static and dynamic seals are called oil seals. The representative form of oil seals is TC oil seals, which are double-lip oil seals with self-tightening springs and fully covered with rubber. Generally speaking, oil seals often refer to this type of rotating oil seal.

[0003] The utility model patent application document with publication number "CN209067841U" discloses a combined rotary oil seal for a gearbox, which is mainly composed of an inner oil seal, an outer oil seal and an outer frame. This technical solution has the advantages of good sealing effect and compact structure, and solves the defects of the existing rotating shaft oil seal, such as poor sealing and dustproof effect and short service life.

[0004] The gearbox combined rotary oil seal disclosed in the above document has the following defects: after the gearbox combined rotary oil seal has been used for a period of time, the retaining spring inside the rotary oil seal is easily fallen off, and the sealing lip cannot be tightened. Since the retaining spring is placed inside the rotary oil seal, the process of reinstalling the retaining spring is relatively troublesome.

[0005] It can be seen from this that the existing gearbox combined rotary oil seal does not have a structure for locking the hoop spring, and it is necessary to improve the existing shortcomings and provide a rubber seal for automotive oil seals. Utility Model Content
