Embedded framework oil seal structure

Abstract

The invention discloses an embedded framework oil seal structure. The structure comprises an oil seal body, an embedding part penetrates through the oil seal body, and the embedding part comprises a head part and a tail part; an inserting piece is arranged on one end face of the tail part, and a groove allowing the inserting piece to be placed in is formed in one end of the head part; a gap is reserved in the surface, in contact with the tail part, of the head part. The embedded framework oil seal structure is provided with the embedding part, a plug rod, an upper oil drainage hole and a loweroil drainage hole; an embedded mode is adopted, the inserting piece is placed into the groove, and the effect of end-to-end connection is achieved; the pressure from the shaft surface is relieved through the movement of the inserting piece in the groove, so that the oil seal body is prevented from being distorted or deformed; when the shaft surface needing to be oiled, lubricating oil flows out along the upper oil drainage hole and the lower oil discharge hole, so that the problem that oiling cannot be achieved is solved; meanwhile, the plug rod is in contact with a framework to assist the framework in keeping the structural tension, and the structure is suitable for different working conditions and brings better application prospects.

Description

technical field [0001] The invention relates to the field of oil seals, in particular to a mosaic skeleton oil seal structure. Background technique [0002] Skeleton oil seal is a typical representative of oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to let the lubricating oil leak. The skeleton is like a concrete component. The steel bars inside play a role of reinforcement and enable the oil seal to maintain its shape and tension; the existing skeleton oil seal structure has certain disadvantages in use, the rubber body of the oil seal is easily twisted or deformed by the pressure of the axial surface, and It cannot be restored after deformation, which affects the sealing and isolation effect of the oil seal. At the same time, when the oil in the oil groove needs to be passed into the sha...

[0002] Skeleton oil seal is a typical representative of oil seal. Generally speaking, the oil seal refers to the skeleton oil seal. The function of the oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the external environment, so as not to let the lubricating oil leak. The skeleton is like a concrete component. The steel bars inside play a role of reinforcement and enable the oil seal to maintain its shape and tension; the existing skeleton oil seal structure has certain disadvantages in use, the rubber body of the oil seal is easily twisted or deformed by the pressure of the axial surface, and It cannot be restored after deformation, which affects the sealing and isolation effect of the oil seal. At the same time, when the oil in the oil groove needs to be passed into the shaft surface, the lack of a connected structure and the introduction of lubricating oil bring certain disadvantages during use. influence, for this reason, we propose a mosaic skeleton oil seal structure
