Abstract
The utility model discloses an electromotor comprising a front end cover, a rear end cover and a rotating assembly which is mounted in the end covers, wherein opening parts of the front end cover and the rear end cover are respectively provided with surrounding edges which extends outward, the periphery of each surrounding edge is provided with screw bolt holes, a sealing groove is arranged on each surrounding edge, and a sealing ring is arranged in each sealing groove. Compared with the technology of the prior art, the electromotor is characterized in that a combination face of the front end cover and the rear end cover is added through the surrounding edges, each sealing ring is embedded in the sealing groove on each surrounding edge, sealing effect of a combination part of the front end cover and the rear end cover is improved, foreign matters can be prevented from entering the electromotor, and therefore electromotor performance is stable, and long service life can be realized.
Description
Technical field
The utility model relates to a kind of motor.
Background technology
The application of motor is very extensive, is used as the active force source in the electrical equipment.Existing motor arranges sealing ring at the contact point of forward and backward end cap and rotating shaft usually, and the front and back ends cover bolt is twisted and to be closed fixingly, reaches good waterproof effect.But, when if the environment for use of motor is more abominable, as range hood motor, motor for washer etc., need stronger sealing property, the front and back ends cover bolt is twisted and is closed fixing mode and be difficult to satisfy, because no matter end cap is drawing and forming or casting, the opening that all can not guarantee end cap is absolute smooth and smooth, and is after tightening with bolt, gapped all the time, oil, water etc. very easily enter motor internal, influence motor performance.
The utility model content
The purpose of this utility model is to provide a kind of motor at above-mentioned the deficiencies in the prior art, can strengthen sealing effectiveness, and stable operating performance increases the service life.
For achieving the above object, the technical solution of the utility model is: a kind of motor, comprise front end housing, rear end cap and be installed in the interior runner assembly of end cap, described front end housing and rear end cap are respectively arranged with outward extending surrounding edge at opening part, offer bolt hole around the surrounding edge, also offer seal groove on the described surrounding edge, be placed with sealing ring in the seal groove.
As the further setting of such scheme, described seal groove and rear end cap concentric.
The beneficial effects of the utility model are: compared with prior art, surrounding edge has increased the faying face of front end housing and rear end cap, sealing ring is embedded in the seal groove on the surrounding edge, promoted the sealing effectiveness of front end housing and rear end cap junction, prevent that foreign matter from entering into motor internal, make motor performance more stable, useful life is more permanent.
