Description
Technical field
The utility model relates to technical field of sealing technology, specifically relates to a kind of New-type electric machine bearing chamber plug cock.
Background technique
The plug cock of oil-lubricated bearing motor needs to have good sealing and ease for operation.
Traditional plug cock roughly has two kinds:
One is rubber oil plug, and this plug cock manually-operable does not need instrument, is applicable to on-the-spot maintenance of motor.Shortcoming is easy ageing failure, and sealability is bad, and dust granule and water enter bearing chamber directly will affect bearing life.
Another kind is standard plug cock, and this plug cock is for being threaded, and inner side adds seal ring, good seal performance.Shortcoming is complex operation, needs spanner just can open, is unsuitable for on-the-spot maintenance of motor.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of New-type electric machine bearing chamber plug cock, effective waterproof and dustproof, good seal performance.
For solving the problems of the technologies described above, the utility model provides following technological scheme: a kind of New-type electric machine bearing chamber plug cock, comprise flexible sealing cock body, also comprise handle, limiting stopper, protecting cover, screw rod, fixed plate, nut, through hole is provided with in the middle part of described protecting cover, described screw rod is interspersed in through hole, screw rod is provided with limiting stopper, described limiting stopper is arranged at protecting cover top, screw rod upper end is provided with handle, screw rod is also provided with the cylindrical pliable sealing cock body coaxial with it, described flexible sealing cock body is arranged at below protecting cover, flexible sealing cock body is provided with frustoconic shape cavity in the middle part of lower end, flexible sealing cock body lower end is provided with the fixed plate with its laminating, described fixed plate bottom screw rod is provided with the nut matched with screw rod.
The scheme of further optimization, described protecting cover lower end is provided with inside turning edge.
The scheme optimized further again, described flexible sealing cock body periphery is provided with screw thread hangnail.
The scheme optimized further again, described handle is handwheel.
The scheme optimized further again, described protecting cover and fixed plate are corrosion resistant plate impact briquetting.
The scheme optimized further again, described flexible sealing cock body is fluorine rubber material.
The beneficial effect that the utility model compared with prior art has is: the utility model is by arranging protecting cover; effectively prevent external dust and water from entering in bearing chamber oil filler; the setting of limiting stopper and fixed plate; flexible sealing cock body is fixed on screw rod; ensure that the integrity of plug cock; flexible sealing cock body is played a protective role, considerably increases the working life of plug cock, handle convenient operation is set.
