Fixed-shaft type lubricating-sealing mechanism of rotary shaft

Abstract

The invention discloses a shaft-fixed lubricating and sealing mechanism for a rotating shaft, which comprises a fixed-distance shaft, an oil tank cover, a front sealing cover, a fixed cover and a rear sealing cover. The front end of the fixed-distance shaft is welded with a transmission shaft. The rear end of the shaft is welded with a drive shaft, and the outer part of the transmission shaft is provided with a front sealing cover; the rear end of the front sealing cover is connected to the front fuel tank cover through the front bolt, and the front fuel tank cover is connected to the fuel tank cover through screws. The rear end of the oil tank cover is connected to the rear oil tank cover; the diameter of the distance shaft is larger than that of the transmission shaft and the drive shaft, and the distance shaft is installed in the lubricating oil chamber, which effectively limits the position of the distance shaft to prevent the When the distance shaft rotates, it shakes back and forth, which improves the stability of its rotation. The lubricating oil in the oil guide chamber is conveniently injected into the lubricating oil chamber, which effectively lubricates the rotation of the distance shaft, reduces the wear of the distance shaft, and facilitates the maintenance of the oil tank cover. The assembly and disassembly of the shell is convenient for regular replacement of lubricating oil; the sealing effect is good, and it has a good locking effect.

Description

technical field [0001] The invention relates to the technical field of rotary shaft sealing machinery, in particular to a shaft-fixed lubricating and sealing mechanism for a rotary shaft. Background technique [0002] The sealing structure of the rotating shaft is a component that prevents foreign impurities from entering the inside of the rotating shaft during the use of the rotating shaft, and plays a good guiding role when the rotating shaft rotates. The existing rotating shaft sealing mechanism only has a certain sealing effect. It is sleeved on the rotating shaft and cannot be well limited when rotating, resulting in the sealing mechanism shaking back and forth or even sliding relative to the rotating shaft, and the stability is poor; and the existing The sealing mechanism lacks the necessary lubricating mechanism, resulting in serious wear and tear of the rotating shaft after a period of use, which affects the service life of the rotating shaft; disassembly and assembl...
