Abstract
The utility model relates to a three-phase asynchronous motor with a modified double-sealed device. The three-phase asynchronous motor comprises a housing, an upper end cap and a lower end cap. A first connecting lug and a second connecting lug are made on the housing and the upper end cap respectively. A first through hole is made on the first connecting lug, and a second through hole is made on the second connecting lug. Bolts for fixing the housing and the upper end cap are disposed on the first through hole and the second through hole. The housing and the lower end cap are also fixed by bolts. The modified double-sealed device is arranged between the housing and the upper end cap and comprises a sealing ring mounting groove made on the inner wall of the housing. The sealing ring mounting groove is provided with a sealing ring which is sealed with a circular outer wall of an upper end cap connecting part. One of the first through hole and the second through hole is a screw hole. The three-phase asynchronous motor has the advantage that the housing and the end caps can be fixed through the bolts without nuts.

For reaching the technical scheme that foregoing invention purpose the utility model adopted be:
Threephase asynchronous machine with modified model double seal; Comprise shell and upper and lower end cap; Be shaped on first on said shell and the said upper end cover respectively and be connected ear and be connected ear with second, said first connects on the ear and is shaped on first through hole, and said second connects on the ear and be shaped on second through hole; Said first through hole and said second through hole are provided with the bolt that said shell and said upper end cover are fixed; Also through bolt, be provided with the modified model double seal between said shell and the said upper end cover between said shell and the said bottom end cover, said modified model double seal comprises on the inwall of shell and is shaped on the first sealing ring mounting groove; The said first sealing ring mounting groove is provided with first sealing ring, and said first sealing ring seals with the annulus outer wall of upper end cover connecting portion mutually; The annulus outer wall bottom of said upper end cover is shaped on the second sealing ring mounting groove, and the said second sealing ring mounting groove is provided with second sealing ring of cooperation, and said second sealing ring seals with the sidewall of the said second sealing ring mounting groove and the inwall of cover top portion mutually; The top of the sidewall of the said first sealing ring mounting groove is outward-dipping, and the bottom of the sidewall of the said second sealing ring mounting groove slopes inwardly; It is characterized in that said first through hole and said second one aperture are screw.
Said first through hole is a screw, and the nut of said bolt is connected the ear contact with said second.
Said second through hole is a screw, and the nut of said bolt is connected the ear contact with said first.
As further optimization, also be provided with said modified model double seal between said shell and the said bottom end cover to technique scheme.
The utility model significantly improves with respect to the prior art sealing property, and can prolong the useful life of this threephase asynchronous machine owing between shell and end cap, be provided with the modified model double seal.First through hole and second one aperture are screw, but make bolt need not nut just fixed housing and upper end cover, and be easy for installation.And the nut of screwing on is realized double fixed, strengthens fixed effect.
Further specify below in conjunction with the execution mode of accompanying drawing the utility model.
