The utility model machine bearing seal arrangement, comprise inner ring blind flange, inner ring blind flange is fixed on bearing support right-hand member, rotating shaft is arranged on bearing support by bearing, bearing outer ring right side is resisted against on inner ring blind flange, outer shroud spacer is provided with between inner ring blind flange and rotating shaft, bearing inner race right side is resisted against on the left side of outer shroud spacer, outer shroud spacer right-hand member is provided with locking nut, inner ring blind flange is provided with inner groovy, outer shroud spacer is provided with annular boss one, annular boss one is flush-mounted in inner groovy to coordinate and forms labyrinth seal, bearing support left side is provided with annular groove, the shaft shoulder left end of rotating shaft is provided with the oily spacer of gear, keep off oily spacer and be provided with annular boss two, annular boss two is flush-mounted in annular groove to coordinate and forms labyrinth seal, keeping off oily spacer is fixed in rotating shaft, bearing support two ends labyrinth seal structure, effectively raise sealing effect and sealability.
The oily spacer of described gear and rotating shaft fixed connection place arrange seal ring, have effectively completely cut off the invasion of exogenous impurity, have well protected bearing, improve the working life of bearing.
The left side of the oily spacer of described gear will be given prominence to bearing support left side and is not less than 5mm, and when rotating shaft vertically uses, lubricant oil drops on the oily spacer left side of gear, because most of lubricant oil can throw away by the effect of centrifugal force, thus sealing effect is strengthened.
Described bearing support is provided with oil drainage hole one, oil drainage hole one is positioned at bearing support left end and communicates with annular groove bottom surface, and when lubricant oil and cutting oil flow into maze trough along the oily spacer outer wall of gear, the oil drainage hole one on bearing support flows out.
Described inner ring blind flange is provided with oil drainage hole two, and oil drainage hole two communicates with inner groovy bottom surface, and when lubricant oil and cutting oil flow into maze trough along outer shroud spacer outer wall, the oil drainage hole two on inner ring blind flange flows out.
Compared with prior art, the utility model has the advantage of:
Sealing structure is simple, it is simple and easy to assemble, cost is low; Bearing support two ends are labyrinth seal structure; keep off oily spacer and have the effect of getting rid of oil concurrently; effectively raise sealing effect and sealability, even if having a small amount of lubricant oil and cutting oil to enter into inside, labyrinth, also flow out by oil drainage hole; Bearing inner can not be entered; keep off between oily spacer and rotating shaft and be provided with seal ring, more improve sealing effect, effectively completely cut off the invasion of exogenous impurity; well protect shaft bearing, improve the working life of shaft bearing.
