Abstract
The utility model discloses a mounting structure for a motor end cap and a stator iron core, comprising an end cap (1) and a stator iron core (2), wherein the middle of the stator iron core (2) is provided with a through hole (21) for mounting a rotor assembly, outside the through hole (21) and on the stator iron core (2) there is provided a plurality of positioning holes (22), the bottom surface (11) of the end cap (1) extends to form a plurality of positioning bosses (12), the positioning bosses (12) are embedded into the positioning holes (22), and the bottom surface (11) of the end cap clings to the end face of the stator iron core (2). Through changing the cooperation structure of the end cap and the stator iron core, the mounting structure resolves the problem that the end cap and the stator iron core are bad in coaxiality because of being not in the same plane, thereby ensuring the motor to normally work.
Description
Technical field:
The utility model relates to the mounting structure of a kind of electric motor end cap and stator core, belongs to two utmost point motor with cup rotor fields.
Background technology:
Traditional 82 structures, two utmost point motor with cup rotor, end cap is directly installed on the stator core, and the bottom surface of end cap is not directly to contact with the end face of stator core; Generally be employed in the end cap bottom surface a plurality of boss are set, contact with the end face of stator core through boss, this structure must make boss be positioned at same horizontal plane; Difficulty of processing is bigger, causes easily between end cap and stator core to have the space, and concentricity is relatively poor; The stator and rotor air gap is uneven when causing the electrical power operation, and the severe patient stator and rotor are wiped mutually, cause degradation; Even stuck phenomenon can appear, there is potential safety hazard.
Summary of the invention:
The purpose of the utility model provides the mounting structure of a kind of electric motor end cap and stator core; Through changing the fit structure of end cap and stator core; Solve because the concentricity difference problem that end cap and stator core do not cause at grade assurance motor operate as normal.
The purpose of the utility model is to be achieved through following technical scheme.
The mounting structure of a kind of electric motor end cap and stator core; Comprise end cap and stator core; Offer the through hole that rotor assembly is installed in the middle of the stator core, on the through hole outside, stator core, some location holes are set, some positioning boss are extended in the bottom surface of end cap; Positioning boss embeds in the location hole, and the end cap bottom surface is adjacent to the stator core end face.
The bottom surface outer ledge of above-mentioned described end cap extends baffle plate downwards, and baffle plate covers on the lateral surface of stator core.
Offer installing hole in the middle of the above-mentioned described positioning boss, installing hole extends to the end cap end face.
The centre of above-mentioned described end cap is provided with bearing chamber.
Above-mentionedly describedly on through hole both sides, stator core, be provided with line embedding groove, stator winding is wound in the line embedding groove.
The quantity of above-mentioned described some location holes is 2, is symmetrically distributed in the both sides of stator core.
The quantity of above-mentioned described some positioning boss is 2, is symmetrically distributed on the end cap.
Above-mentioned described end cap and positioning boss are the integrally casting moulding.
The utility model beneficial effect compared with prior art is: 1) the utility model comprises end cap and stator core; Offer the through hole that rotor assembly is installed in the middle of the stator core, on the through hole outside, stator core, some location holes are set, some positioning boss are extended in the bottom surface of end cap; Positioning boss embeds in the location hole; The end cap bottom surface is adjacent to the stator core end face, solves because the concentricity difference problem that end cap and stator core do not cause at grade assurance motor operate as normal; 2) the bottom surface outer ledge of end cap extends baffle plate downwards, and baffle plate covers on the lateral surface of stator core, reasonable in design, and baffle plate plays position-limiting action; 3) end cap and positioning boss are the integrally casting moulding, and be simple in structure, reduces technology difficulty.
