Technical field
The utility model relates to a kind of motor part, relates in particular to a kind of material-saving light-type electromagnetic-braking three-phase asynchronous motor front end housing.
Background technology
Electromagnetic-braking three-phase asynchronous motor is as a kind of driven by power equipment, owing to thering is the advantages such as braking is rapid, simple in structure, reliability is strong, be widely used in that various requirement stops fast and accurately in the plant equipment and transmission device of location, the construction site that is especially applied in the fields such as building industry is as the driving arrangement of hanging basket.The electromagnetic-braking three-phase asynchronous motor that is applied at present hanging basket structurally mainly comprises stator, rotor, armature spindle, front end housing, rear end cap, housing, electromagnetic brake and protective cover thereof, wherein stator, rotor are arranged in housing, front end housing, rear end cap are sealed on housing two ends by seam respectively, and front end housing is the important composition part of electromagnetic-braking three-phase asynchronous motor.Its inner face of existing front end housing is provided with the seam and the bearings cover that are connected with housing, and rotor puts in bearings by bearings, and the outer face of front end housing is the mounting plane being connected with reductor.
The major technique defect that existing front end housing exists is: lid is irony cast member, and lid is abundant, not only consume material but also gain in weight, especially the use needs that hang blue equipment in the fields such as inadaptable building.How, for the problems referred to above, existing front end housing structure is improved, under the prerequisite that ensures its bulk strength, reduced material, weight reduction becomes manufacturing firm's concerned issue.
Utility model content
Main purpose of the present utility model is for the problems referred to above, and a kind of material-saving light-type electromagnetic-braking three-phase asynchronous motor front end housing is provided.
The utility model solves the technical scheme that its technical problem adopts:
A kind of material-saving light-type electromagnetic-braking three-phase asynchronous motor front end housing, comprise circular lid, be provided with the bearings cover of support rotor axle bearing and the seam being connected with housing at described lid inner face, lid outer face is provided with the circular seam table top being connected with reductor, it is characterized in that, attenuate plane with reinforcement is set on front end housing inner face, at least one groove is set on its outer face.
Planar annular between seam on described lid inner face and bearings cover is arranged to annular attenuate plane, the ring support set reinforcement that runs through described annular attenuate plane connecting with one in described annular attenuate plane and many uniform radial reinforced ribs, the one-tenth-value thickness 1/10 of described annular attenuate plane reduces 5-6mm than described planar annular one-tenth-value thickness 1/10.
On described lid outer face, around described circular seam table top is uniform multiple arc grooves are set.
The beneficial effects of the utility model are: by the improvement to existing electromagnetic-braking three-phase asynchronous motor front end housing structure, on end face, be provided with the attenuate plane with reinforcement therein, on outer face, be provided with all arc grooves of ring, make part plate body attenuate, reduce with material, by statistics can material-saving 10-20%, reach the effect of saving material, weight reduction, be more conducive to the driving arrangement as hanging basket.
Brief description of the drawings
Fig. 1 is outer face of the present utility model structural representation;
