Abstract
The utility model discloses a seal structure for an air-cooled motor. The seal structure comprises a housing, and a wiring box fixedly mounted on a cooling air plate, wherein the housing is provided with an opening for being connected with a power line. The seal structure is characterized in that, the wiring box and the opening are sealed by a metal pressing ring and a rubber gasket. The seal structure is advantageous in that, the wiring box and the opening of the housing are sealed by the metal pressing ring and the rubber gasket, the length of the conventional rubber gasket is shortened, and the rubber gasket is not easy to be deformed, ensuring the seal effects; besides, the metal pressing ring and the rubber gasket are combined so as to be adaptive to cooling air plates of different thicknesses.
Description
Technical field
The utility model relates to a kind of ventilated machine, relates in particular to a kind of hermetically-sealed construction of ventilated machine.
Background technology
Ventilated machine, especially air-cooled servomotor, its cooling air channel is longer, makes the length of the cooling aerofoil on the motor account for more than 2/3 of motor case length, and terminal box is installed on the cooling aerofoil.Because the power line of motor need be connected to terminal box inside, therefore, must be in casing and the upper shed of cooling aerofoil, so that the passing of power line, but motor must carry out encapsulation process.Sealing between terminal box and the casing opening is to seal by rubber ring at present, owing to be separated with the cooling aerofoil between terminal box and the casing, therefore make that the length of rubber ring is long, during assembling, rubber ring is easy to generate distortion, and in use for some time, rubber ring also can produce distortion, influences sealing effectiveness.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hermetically-sealed construction that guarantees the ventilated machine of the sealing effectiveness between terminal box and the casing opening.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of hermetically-sealed construction of ventilated machine, comprise casing and the terminal box that is fixedly mounted on the described cooling aerofoil, described casing is provided with the opening that is used to connect power line, passes through metal trim ring and rubber seal between described terminal box and the described opening.
Described metal trim ring and described opening sealing and fixing, described rubber blanket is arranged between described metal trim ring and the described terminal box.
Be coated with fluid sealant between described metal trim ring and the described opening.
Described rubber blanket is arranged on the described opening, and described metal trim ring is arranged between described rubber blanket and the described terminal box, described metal trim ring and described terminal box sealing and fixing.
Be coated with fluid sealant between described metal trim ring and the described terminal box.
Compared with prior art, the utility model has the advantages that, shortened the length of traditional rubber ring, make rubber blanket not yielding, guaranteed sealing effectiveness owing to pass through metal trim ring and rubber seal between terminal box and the shell opening; And the combination of employing metal trim ring and rubber blanket, can adapt to different cooling air plate thickness.

Fig. 2 is a partial sectional view of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of hermetically-sealed construction of ventilated machine, comprise casing 1 and be fixedly mounted on the terminal box of cooling off on the aerofoil 23, casing 1 is provided with the opening 11 that is used to connect power line 4, opening 11 is provided with metal trim ring 5, be coated with fluid sealant between metal trim ring 5 and the opening 11, be provided with rubber blanket 6 between metal trim ring 5 and the terminal box 3.
In the foregoing description, except that structure shown in the accompanying drawing, can also be with the location swap of metal trim ring 5 and rubber blanket 6, promptly rubber blanket 6 is arranged on the opening 11, metal trim ring 5 is arranged between rubber blanket 6 and the terminal box 3, is coated with fluid sealant between metal trim ring 5 and the terminal box 3.
