Abstract
The invention discloses a sealing structure for a drive shaft. The sealing structure comprises a shell and the drive shaft mounted on the shell. A through hole allowing the drive shaft to penetrate is formed in the shell. A bearing is arranged between the drive shaft and the shell. The side, located outside the shell, of the through hole is fixedly provided with a bearing end cover. The outer side of the drive shaft is sleeved with the bearing end cover. The bearing end cover and the shell are detachably fixed through a bolt. The side, facing the interior of the shell, of the bearing end cover is provided with an annular protruding extending portion in a protruding extending manner. The tail end of the protruding extending portion abuts against the rim of the outer side of the bearing. A step portion is formed on the side, facing the drive shaft, of the bearing end cover in a recessed manner. The drive shaft is further sleeved with a baffle ring. The periphery of the baffle ring is provided with an annular sealing portion extending outwards in a protruding manner. The sealing portion is located on the step portion of the bearing end cover in a matched manner. In a machine tool transmission, rotation between the drive shaft and a transmission body is more stable, the service life is long, and besides the airtightness is good.
Description
Technical field

Being provided with bearing between described housing, described through hole is positioned at the side of described hull outside and is fixed with bearing (ball) cover,
Described bearing (ball) cover is sheathed on the outside of described drive shaft, passes through between described bearing (ball) cover and described housing
Bolt is detachably fixed, and described bearing (ball) cover protrudes out protruding out of annular towards the side of described enclosure interior
Portion, the end of this convex extension part is held in the outer ledge of described bearing, and described bearing (ball) cover drives towards described
The recessed stage portion that is formed in the side of moving axis, described drive shaft is also arranged with baffle ring, described baffle ring
Surrounding outward has the sealing of annular, the cooperation of this sealing to be positioned in the stage portion of described bearing (ball) cover.
Preferably, in above-mentioned driving axle sealing structure, described sealing contacts with described stage portion
Face is jagged matsurface.
Preferably, in above-mentioned driving axle sealing structure, described bearing is taper roll bearing.
Preferably, in above-mentioned driving axle sealing structure, described bearing is near the one of described enclosure interior
End is fixed with elastic baffle ring, and described elastic baffle ring is arranged in described through hole.
Preferably, in above-mentioned driving axle sealing structure, one end that described baffle ring deviates from described housing is solid
Surely nut, described nut sleeve is had to be located in described drive shaft.
Compared with prior art, it is an advantage of the current invention that: in the lathe gearbox of the present invention, drive shaft
And the rotation between casing is more stable, high life, and good airproof performance.
