Abstract

The invention discloses a shaft sleeve and a box-type oil sea. The shaft sleeve comprises a straight pipe, a ring-shaped frame and a first rubber body, wherein a shoulder part is arranged on the outersurface of the straight pipe; the ring-shaped frame is mounted on the outer side of the straight pipe in a sleeving manner; the end surface of the ring-shaped frame is propped against the shoulder part; the first rubber body comprises a first rubber part, a second rubber part and a third rubber part; the first rubber part fits the inner surface of the straight pipe; the second rubber part fits the ring-shaped frame and gets close to one side of the shoulder part; and the third rubber part fits the outer surface of the straight pipe, and is connected with the first rubber part and the second rubber part. According to the shaft sleeve and the box-type oil seal, the shaft sleeve strength can be improved, the deformation can be reduced, and the sealing effect can be ensured.

Description

technical field [0001] The invention relates to an oil seal structure, in particular to a shaft sleeve and box type oil seal. Background technique [0002] Agricultural machinery is equipment dedicated to agricultural production. Due to the wide variety of geographical environments, the work of agricultural machinery is very complex and harsh, and it is prone to shock loads, such as accidental impacts, contact with stones, etc. [0003] In order to protect the bearings of agricultural machinery, cartridge oil seals have been designed. [0004] Structurally, the cartridge oil seal has a shaft sleeve, a first ring and a second ring oppositely arranged. [0005] Wherein, the first ring and the second ring are rotatably fitted on the shaft sleeve, the first ring and the second ring are fixed, and a lubricating chamber is formed between the first ring and the second ring. [0006] At the same time, the shaft sleeve is formed by sheet metal stamping, and has a pipe body and a r...
