Abstract
The utility model discloses an installation structure of an end cover of a motor. The installation structure comprises a front end cover (1) and a rear end cover (2); an upper flange (11) and a lower flange (21) are respectively arranged at a joint of the front end cover (1) and the rear end cover (2); a plurality of salient points (3) are protruded on the bottom of the upper flange (11) or the bottom of the lower flange (21); a plurality of grooves (4) are opened on the other flange; and the salient points (3) are embedded into the grooves (4). The installation structure has advantages of simple structure, convenient installation, high concentricity of bearing chambers of the front end cover and the rear end cover, high precision of assembling, and low noise and vibration; besides, normal service life of the motor can also be improved.
Description
Technical field:
The utility model relates to a kind of electric motor end cap mounting structure.
Background technology:
Traditional electric motor end cap mounting structure; Stator core and front end housing or rear end cap adopt interference fit; Fastening through screw after another end cap and the stator core employing matched in clearance, this structure front end lid and rear end cap upper bearing (metal) chamber cannot say for sure to demonstrate,prove concentricity problems such as noise vibration to occur; Increase the loss of electric machine, shorten motor normal useful life.
Summary of the invention:
The purpose of the utility model provides a kind of electric motor end cap mounting structure, and it is simple in structure, and is easy for installation, and end cap bearing chamber concentricity is high, and assembly precision is high, reduces noise vibration, improves motor useful life.
The purpose of the utility model is achieved through following technical proposals.
A kind of electric motor end cap mounting structure; Comprise front end housing and rear end cap, front end housing is respectively arranged with the upper overturning and following flange that is used to be connected with rear end cap at joint, perhaps protrude some salient points on the flange bottom surface down at upper overturning; Offer some grooves on another flange, salient point embeds in the groove.
Above-mentioned described some salient points are 3, evenly circumferentially are distributed on upper overturning or the following flange, and some grooves are 3, and are corresponding with the salient point position, evenly circumferentially are distributed in down on flange or the upper overturning.
Above-mentioned described front end housing upper overturning outer ledge stretches out some installation feet; Installation foot is provided with installing hole; Flange extends mounting panel under the rear end cap, and mounting panel offers some installing holes down, and screw passes down installing hole and last installing hole couples together installation foot and mounting panel.
Above-mentioned described mounting panel is provided with some through holes that motor is installed external equipment that are used for.
Above-mentioned described rear end cap, following flange and mounting panel are the one cast aluminium formings.
Above-mentioned described front end housing is the iron-clad end cap.
The utility model compared with prior art has following effect: 1) the utility model is offered some grooves through perhaps protruding some salient points on the flange bottom surface down at upper overturning on another flange; Salient point embeds in the groove; Increase detent mechanism, guarantee the concentricity of front end housing and rear end cap upper bearing (metal) chamber, improve assembly precision; Reduce noise vibration, increase motor useful life; 2) some salient points are 3, evenly circumferentially are distributed on upper overturning or the following flange, and some grooves are 3, and are corresponding with the salient point position, evenly circumferentially are distributed in down on flange or the upper overturning, and stressed even, Stability Analysis of Structures is fastening; 3) rear end cap, following flange and mounting panel are the one cast aluminium formings, and front end housing is the iron-clad end cap, and is simple in structure, is suitable for to produce in batches.
