Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Shown in Fig. 3,4, it is the schematic diagram of the utility model motor stator assembly structure embodiment.The motor stator assembly structure of present embodiment comprises stator 32 and casing 31, and wherein casing 31 has bore of stator, the external diameter coupling of the internal diameter of this bore of stator and stator 32, thus stator 32 can be assembled in the said stator chamber by modes such as hot jackets.For the ease of realizing accurately location (no frock) when the assembling stator 32, be provided with limiting section in the said machine casing 31, this limiting section is positioned at the first end (stator 32 is placed into bore of stator from the second end of bore of stator) of bore of stator.And this limiting section protrudes from the inwall of bore of stator.At the opposite side of limiting section (namely a side) relative with bore of stator, can assemble the miscellaneous part of motor, for example end cap etc.
Especially, to protrude from the height of bore of stator inwall be 0.3 ± 0.05mm to above-mentioned limiting section.Particularly, this limiting section protrudes from the height of bore of stator inwall can be determined according to case material, size etc., only need after casing 31 heating this limiting section can limit stator from this limiting section by getting final product.
In actual applications, above-mentioned limiting section can adopt limited step, as shown in Figure 4.At this moment, the diameter of the inwall of the casing 31 on the left of bore of stator is less than the diameter of bore of stator inwall, its diameter difference is that 0.6 ± 0.1mm(occurrence is determined by the size of casing, the coefficient of expansion of case material etc.), thereby stator 32 is resisted against on this limited step when being inserted into casing 31, need not frock and can realize accurate location.Owing to casing 31 adopts tensioning members mostly, when limiting section adopts the limited step structure, only the inwall of the casing 31 after stretching is finished need be processed bore of stator by modes such as cuttings and get final product.
In addition, above-mentioned limiting section also can adopt a salient point or a plurality of salient point (a plurality of salient points are positioned at the plane perpendicular to stator axis).Above-mentioned salient point can pass through at the one or more screws of casing 31 processing (this screw is from the through inwall of the outer wall of casing), and uses bolt realization that is screwed to this screw and makes it protrude from casing inner wall.
Above-mentioned limiting section also can be adopted as structure realizations such as bulge loop, and this bulge loop is positioned at the plane perpendicular to stator axis.
The utility model also provides a kind of motor case, and this casing comprises bore of stator and be positioned at the limiting section of the first end of bore of stator that wherein the external diameter of the internal diameter of bore of stator and stator coupling and stator are installed in the bore of stator; Limiting section protrudes from the inwall of bore of stator.
Especially, to protrude from the height of bore of stator inwall be 0.3 ± 0.05mm to above-mentioned limiting section.Particularly, this limiting section protrudes from the height of bore of stator inwall can be determined according to case material, size etc., only need after the casing heating this limiting section can limit stator from this limiting section by getting final product.
In actual applications, above-mentioned limiting section can adopt limited step.This limited step processes in the following manner: the inwall of the casing after stretching is finished processes bore of stator by modes such as cuttings, and keeps the outer casing inner wall of bore of stator.
In addition, above-mentioned limiting section also can adopt a salient point or a plurality of salient point (a plurality of salient points are positioned at the plane perpendicular to stator axis).Above-mentioned salient point can pass through at the one or more screws of casing processing (this screw is from the through inwall of the outer wall of casing), and uses bolt realization that is screwed to this screw and makes it protrude from casing inner wall.
