Abstract
The utility model discloses a coal mine motor rotating shaft dynamic sealing structure which comprises a motor outer cover, a waterproof sealing pad, an O type sealing ring, a sealing end cover, a static sealing waterproof ring, a dynamic sealing waterproof ring, a sealing airflow chamber, a dynamic sealing dustproof ring and a bearing. The sealing end cover is fixed on the motor outer cover. The waterproof sealing pad is arranged on the lower end of the motor outer cover. The O type sealing ring is arranged on the upper end of the sealing end cover. A motor rotating shaft is sheathed with a rotating waterproof sealing ring. The rotating waterproof ring is provided with a cylindrical face lip and an end face lip. Concave-convex stripes are designed at the bottom, thus airflow is produced when the shaft rotates. According to the utility model, the unilateral interference amount of cylindrical face sealing and end face sealing is less than 1.5mm; the bearing is not easily burned; the interference amount is small; wear of the sealing structure is reduced; and the service life of the whole sealing structure is improved.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction of motor, particularly a kind of rotating shaft movable sealing structure that is applicable to the big motor in colliery.
Background technology
The big machine shaft movable sealing in existing colliery IP66 structure is outside framework oil seal.The monolateral interference of outside framework oil seal and machine shaft is greater than 1.5mm, and has spring to hold tightly, and friction temperature is too high greater than 100 ° of bearing chamber temperature rises, and big in addition motor shaft hardness is low easy to wear, causes the protection life-span short.
Summary of the invention
Goal of the invention of the present utility model is the deficiency for customer service above-mentioned background technology, and a kind of outstanding long service life that has is provided, and is difficult for burning the hermetically-sealed construction of motor bearings.
The technical solution of the utility model is: a kind of mining motor rotating shaft movable sealing structure, comprise the motor enclosing cover, waterproof sealing gasket, the O RunddichtringO, end cover, the static seal waterproof ring, the dynamic seal water proof ring, sealing airflow chamber, the movable sealing dust ring, bearing, it is characterized in that described end cover is fixed on motor and covers outward, described waterproof sealing gasket is arranged at the lower end of motor enclosing cover, described O RunddichtringO is arranged at the upper end of end cover, on machine shaft, also be with the rotation waterproof seal ring, this rotation waterproof ring is provided with cylinder lip and end face lip, bottom design has the concave-convex type striated, makes it produce air-flow when revolving spool.
Described end cover has formed cylinder sealing and end face seal with the rotation waterproof seal ring that rotates with machine shaft, and cylinder seals the monolateral magnitude of interference less than 1.5mm, and the end face seal magnitude of interference is less than 1.5mm, and friction temperature is less than 50 degrees centigrade.
The beneficial effects of the utility model are: end cover of the present invention is fixed on motor and covers outward, rotating waterproof seal ring is enclosed on the machine shaft, rotate with axle, form sealing, rotate the existing cylinder lip of waterproof seal ring, the end face lip is arranged again, simultaneously make the concave-convex type striated, make it when revolving spool, produce air-flow in the bottom.The standstill seal end cap has formed cylinder sealing and end face seal with the rotation waterproof seal ring that rotates with machine shaft, creatively mechanical seal and lip seal molten be one; Cylinder seal the monolateral magnitude of interference less than the 1.5mm end face seal magnitude of interference less than 1.5mm, friction temperature guarantees that less than 50 degrees centigrade the bearing chamber temperature rise is normal, machine shaft is never wornout, it is permanent that degree of protection can keep.
