Abstract
The utility model provides a motor end cover positioning structure, which comprises a stator core (1) and end covers (2). The motor end cover positioning structure is characterized in that a plurality of positioning clamp grooves (3) are arranged on the end face of the stator core (1); a plurality of mounting pins (6) corresponding to the positioning clamp grooves (3) protrude from the end covers (2); and the mounting pins (6) are embedded in the positioning clamp grooves (3). The thickness of the stator core between the end covers is reduced; the axial mounting space is short; the axial cumulative error is significantly reduced; the motor end cover positioning structure is installed conveniently, and is simple in structure, which positions motor end covers more accurately and conveniently in the radial direction; the installed position accuracy of the stator core and the end covers is significantly improved; the electromagnetic air gap of a motor is effectively ensured to be even and the structure is axially concentric; the mechanical stability problem of the running motor and the noise problem are solved.
Description
Technical field:
The utility model relates to a kind of end cap assembling and positioning structure of motor.
Background technology:
The end cap assembling and positioning structure of conventional motors is: will form stator core behind the identical stator punching closed assembly, then end cap is overlayed on the end face of stator core and utilize the nut nut body that stator core is connected with end cap.There is following shortcoming in this assembly structure: 1) because the thickness of stator core is bigger, install by nut nut body and stator core between the two end cap, the axial dimension that stator core is installed between end face in two end cap is long, and axially accumulated error is big, and assembly precision is poor; 2) radial position of stator core and two end cap realizes that by the nut nut body assembly precision is poor, influences the motor reliability of operation; 3) because assembly precision is difficult to assurance, bring mechanical stability and noise problem.4) since the stator core end face contact with end cap, need to guarantee after the japanning of stator core end face evenly, owing to the area of whole stator core end face is big, is difficult to guarantee to demonstrate,prove and coats with lacquer knurl in the assembling process, coat with lacquer the influence of slag installed surface.
Summary of the invention:
The purpose of this utility model provides a kind of end cap assembling and positioning structure of motor, and its adopts embedded cooperation the between the locating groove of end cap installation foot and stator core, and assembling is reliable easy, the assembly precision height.
The technical solution of the utility model is achieved in that
A kind of end cap assembling and positioning structure of motor comprises stator core and end cap, has several locating grooves on the stator core end face, and end cap is extended with some the installation feet corresponding with locating groove, and installation foot is embedded into the locating groove the inside.
The utility model compared with prior art has following advantage: 1) by have several locating grooves on the stator core end face, the installation foot that utilizes end cap to be extended with cooperates with locating groove, reduce the thickness of the stator core between the end cap, axially mounting distance is short, has obviously reduced axial accumulated error; 2) installation foot that utilizes end cap to be extended with cooperates with locating groove, easy for installation, simple in structure, radial location is more convenient, significantly improved the positional precision that stator core and end cap are installed, and the electromagnetism air gap that can effectively guarantee motor is even, and axis of no-feathering solves motor mechanical stability in service and noise problem to one heart; 3) area that takies of locating groove is less, and this avoiding hollow groove structure can effectively guarantee to coat with lacquer in the assembling process knurl, coat with lacquer the influence of slag to installed surface.
At technique scheme, the utility model can also be made following improvement:
Have installing hole on the bottom surface of above-mentioned described locating groove, also have through hole on the installation foot, nut passes installing hole and through hole and couples together with nut, and is simple in structure, easy to manufacture.
The end face contact matching of the bottom surface of above-mentioned described locating groove and installation foot, the bottom surface of draw-in groove and the end face of installation foot all are the planes, scribble skin of paint above, because the area of the bottom surface of draw-in groove is little, lacquer knurl, lacquer slag ratio are easier to handle the installation accuracy in the time of can effectively guaranteeing to assemble.
The madial wall of above-mentioned described locating groove is an arc surface, and the medial surface of installation foot is an arc surface, and madial wall cooperates with medial surface, so can guarantee the concentricity after end cap and stator core assemble, and assembling is simple and precision is high.
The number of above-mentioned described locating groove and installation foot is more than 2 or 2.
Above-mentioned described end cap is metal stretching and molding and has bearing chamber.
Above-mentioned described locating groove is positioned at the edge of stator core, and handling ease is easy to assembly.
