該馬達殼廳由二個碗_殼體部件12及13所構成。此等 099116059 12 201106584 殼體部件係由鋼板製成衝壓彎曲件，且首先各具有在碗底區 域形成軸承支架Μ的碗形區段，其中，緊連軸承支架14 的區域具有圓盤形輪廓，而該輪靡包括一個圓形中央插口 15，用於轉子軸2的軸承16即固定於此插口内。轴承^ 在此係透過彈簧圈29而支承於插口底部3〇。 與轉子軸線X同軸定向的圓環形碗壁，在其遠離於構成為 軸承支架14的碗蓋之末端，與—個徑向向外延伸的圓錐形 覆蓋段17相連，而雜蓋段之徑向末端轉變為—個至少部 分與轉子軸線X同軸定向的覆蓋凸緣1Wb覆蓋凸緣在殼 體部件12《13之相對於定子5的對應位置上延伸，並覆蓋 倒圓的定子區域10之對應邊緣區域。 自覆蓋段17之周向觀察，覆蓋凸緣18上連接有連接片 19 ’ 3亥連接片在殼體部件12、13之相對於定子$的對應位 置上平面平行於定子扇平區9而延伸。此連接片輪靡呈梯 形’包括-個與覆蓋凸緣18之自由外緣齊高延伸的梯形下 ，底、及—辦行於該梯形下底且在垂直方向上（即，沿在轉 子軸線X之延伸方向）與覆蓋凸緣18之自由外緣間隔一定距 離的梯形上底。平行分佈的二個梯職邊之垂錢距，在此 大於定子疊片組沿轉子轴線乂延伸方向之厚度的—半。在此 情況下，當連接片19覆蓋住轉子上之對應扁平區9時，任 一連接片19之自由外緣與轉子5之相對外緣間的距離，均 大致等於覆蓋凸緣18之垂直延伸度。 099116059 13 201106584 對應於定子5上設有四個扁平區9 ’殼體部件12或13上 設有四個連接片19。 圖中位於上方的殼體部件Π之連接片19各具有一個徑向 向外延伸的壓製成型部20，其中，壓製成型部2〇相對於連

安裝區23及24係由分離槽25切割後朝徑向内側按壓而 形成’由此形成多個在徑向上相對於轉子軸線X有一定水平 偏移的區段，其中’透過以如此方式製成的安裝區23及24 之徑向内側區段’可將殼體部件12、13支承於定子5之對 應端面22上。 不可偏移的安裝區23具一個水平延伸的，確切而言，係 平行於對應連接片19之梯形底邊延伸的分離槽25，其中， 被該分離槽切割後被按向徑向内側的區段係卡入覆蓋段17

情況下’朝徑向内側傾斜延伸。 在所示實施例中，安裝區23之曝露區段或簧片26之、、 相 應殼體部件12、13周向的寬度，大約等於定子扁平區9 ^ 相同方向測得之寬度的三分之一。 安裝電動馬達1時，將轉子3插入帶繞組定子5後，藉由 將轉子軸2貫穿一個中央軸承支架孔27，分別於轉子3之 一個末h各安裝一個殼體部件12、13，其中，殼體部件a、 13以其覆蓋段17及覆蓋凸緣18將定子5之邊緣卡住， 精 此，將殼體部件12、13緊密地固定於定子5上。二個殼體 部件12、13之連接片19為重疊，其中，下方殼體部件13 之連接片19嵌入相應的入口 21。在此之後，殼體部件12、 13遂透過其安裝區23及24而分別支承於定子5之相應的 端面22上。 沿轉子軸線X之延伸方向，對殼體部件12及丨3施加約為 1500牛頓米之裝配力P，在此裝配力之作用下，殼體部件 12及13以適當方式進行定向，特定言之，其係使得軸承支 架孔27及用於固定軸承16的插口 15與轉子軸線χ實現精 099116059 16 201106584 確的同軸定向。此外，殼體部件12及13之定向方式另使得 插入插口 15的軸承16之軸向間距符合一規定尺寸。由此， 可對定子5之疊片組高度方面的可能容差進行補償。 藉由用可偏移的安裝區24來支承殼體部件12、13，可對 該等殼體部件進行相對於定子5的相應調整。先以上方殼體 部件12之不可偏移的安裝區23為殼體部件12提供預固定 作用，隨後，在二個殼體部件12及13已定向之情況下，可 偏移的安裝區24,特別是簣片26,利用簀片26所達到之彈 性，使得相應的殼體部件發生用於克服容差的位移及/或傾 斜，在此過程中，簧片26會或多或少進一步朝徑向内側發 生偏移。 先透過三個不可偏移的安裝區23，使殼體部件12精確地 定位於對應定子端面22所在之平面。第四個可偏移的安裝 區24則可藉由可能的變形而與規定平面相匹配。 在殼體部件12及13所設安裝的位置上，將重疊的連接片 19焊接在一起，為此，殼體部件12之連接片19在其壓製 成型部20區域内具有焊接凸起28，以便在實施電阻焊時得 以貫現針對性的電流傳輸。 至此，定子5在軸向及徑向上均被壓緊。 上述設計方案之優點在於，可對定子疊片組高度容差進行 補償，從而進一步降低零件容差要求。此外，亦可避免轉子 軸2之軸承16發生傾斜，此點會在噪聲及使用壽命方面產 099116059 17 201106584 生有利影響。 所有已揭示特徵（自身即）為發明本質所在。故本申請案之 揭示内容亦包含相關/所附優先權文件（在先申請副本)所揭 示之全部内容，該等文件所述之特徵亦一併納入本申請案之 申請專利範圍。附屬項採用可選並列措辭，對本發明針對先

Description of the Invention: [Technical Field] The present invention firstly relates to a money motor including a rotor and a stator. The beans are housed in a motor casing composed of two components, and the shell material is The members simultaneously form the bearing brackets, respectively, and are placed in axial alignment with one another, wherein the corresponding edge regions of the housing members are connected to one another only in such a way that they can be released. [Prior Art] The electric motor of the above type is known to us. In particular, the stator of the rectifying motor and the reluctance motor is housed in a split-type housing, and the section (4) of the piece also constitutes a bracket for fixing. Hemp for supporting the rotor shaft (eg 'ball bearings'). In order to fix the housing parts to the stator, the corresponding edge regions of the housing parts are connected to each other mainly by welding. SUMMARY OF THE INVENTION Improvements have been made. In view of the above prior art, the technical teaching of the present invention is to fix the housing components to accommodate the stator, for the above type; = the subject first and substantially by the object of the patent scope i The corresponding edges form a connecting piece protruding in the vertical direction, and the connecting pieces are overlapped with each other in the horizontal direction in the mounted state, so that 'in the connection>j, preferably only in the material connection 4 area The relative fixing of the housing parts is achieved within. This design provides an easy-to-install embodiment for securing the shell members 099116059 4 201106584 to the stator. Conventional solutions use a wraparound housing receiving portion to join the housing member 'and to cover the stator in a bowl-like manner. In contrast, the present invention employs a vertically protruding connecting piece design' in each housing member. It is especially advantageous in terms of orientation of the scorpion. In this way, it is possible to join the scorpion after the scorpion is placed, and it is also possible to compensate for the manufacturing of the valley difference in a very simple manner. This applies in particular to the case where the housing parts are oriented in a plane transverse to the rotor axis. Since the connecting pieces of the corresponding edges of the respective housing parts overlap each other in the horizontal direction when the mounting state is completed, the connecting piece ' protruding in the vertical direction can be realized during the mounting process to realize the material of the material housing (4) Pre-positioning. In the case where the stator is placed in the valley, the two housing members are fixed to the two housing members in the horizontal direction (4) in the region where the connecting piece is located, and it is difficult to achieve such solidity by soldering the connection hx. The connection between the housing parts can be released by means of destruction. According to a preferred design, the relative mosquitoes of the housing parts are known by the resistance. Compared with the design of the surrounding bowl-shaped flange for the housing parts, the vertical protruding piece can be used. The goal of achieving weight reduction is the same as that of f#, which can keep the shell parts as small as possible in the m疋 area axis (including the characteristics of the patent scope, etc., which will be mainly from the scope of the application) In several aspects, the characteristics of the present invention are carried out. (9), the material characteristics may only correspond to the single feature of the patent application scope 1 or other patent application scopes, or may be significant as an independent special 099116059 201106584. According to a preferred design of the present invention, the stator has a non-circular outer flat/closed area and a flat area. The dice (4) is a reference, and the 90° is sandwiched between the adjacent flat areas in the 'twisting direction. Corner, 苴 half: = the corner area is rounded, and at least approximately - line related processing ^ half (four) and the rotor shaft through the stator = better design, the connection of the shell parts The film corresponds to the purpose of the stator' Obtaining, without or at least not fixing each other for the purpose of:: the outer side of the wall of the corresponding housing part of the back corner area is formed on the stator; =, such covering is only used for 'optionally joining the connecting pieces The connecting portion fixes the housing member tightly to (4). In addition, the 'material connecting piece corresponds to the flat portion of the stator, which facilitates the joining of the body member and the pre-tensioning, and the time-in-place". In the case of / _ corner area, the housing part mounted on the stator can be prevented from twisting, in particular before final fixing of the housing part. According to another preferred embodiment, the housing part is designed as a steel plate. The curved piece and the large bottom of the bowl which constitutes the bearing bracket surround the carrying bowl edge, and the joints are freely protruded from the edge of the bowl in the vertical direction. On the connecting piece, preferably in the heart, a connecting piece on the connecting piece of the yak mother is provided with a press forming And the press forming 4 on the outer surface of the coin, in particular, interacts with the outer surface of the stator in the flat zone to form an entrance for the reverse connecting piece for the other housing part to be inserted into 099116059 6 201106584 . Correspondingly, the connecting piece of the body part of the other housing part is connected to the outer surface of the stator. The connecting piece of the connecting piece to the connecting piece overlaps with each other in the pre-ampere state or the red piece and the opposite directions. The body members ± 〜 are all radially outward along the horizontal field, such that at least part of the section of the # is offset radially outwardly for the reverse connection piece of the connecting piece connection design, _ does not occur 'According to the preferred connection from the connecting piece on the bearing bracket. The way of offset, to. The meal is held in a vertical plane. According to the preferred design, the joints of the joints on the bearing brackets have a trapezoidal shape including a pair of lower bottoms and corresponding to the connection, and The trapezoidal upper part of the trapezoid on the free end of the trapezoidal piece, t, in the private part of the 妒 接 接 接 接 接 Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ Γ The radial protruding position and the 疋S surface are spaced apart by a certain radial distance, and the reverse connection of the two housing parts covers the end between the other sides of the mouth. The end of the money feed piece and the outer surface of the stator are specifically related to the problem. For example, the solution of the first part of the patent scope is to solve the aforementioned problem. The present invention proposes a solution as follows: The fashion corresponds to the corresponding knowledge of the stator 099116059 7 201106584 _L纟 'there are three or more Annan Districts separated from each other in the circumferential direction', at least one of which is designed to be offset. According to the material scheme, the parts of the housing component constituting the bearing bracket are mounted on the corresponding surfaces of the stator in the mounting areas, wherein the mounting areas are preferably provided with local linear positioning members and / σ circumferential women's clothing. The length is from tenths to one-fiftieth of the entire circumference of the reduced cross-sectional area of the housing component.

Instead, the orientation 'the other two is:== the moved ampoule' is oriented parallel to the first-shell component and at the same time = the possible stack height tolerance of the lamination stack is compensated. Zhu Anshang is different. When the housing part is in the position, there is also a mounting area that can be =, and no displacement occurs with respect to the initial position where the force is not applied. The realization of the offset is achieved by the elasticity of the money and the corresponding force in the process, which will overcome the predetermined elasticity and the corresponding offset, so that the Anemon F is adjusted every axial direction.

In this case, it is preferable that the ampoule area on the housing member of the =! curved piece is composed of a plurality of horizontally offset sections divided by the division. The separation groove is separated from the casing member by a section, and is pressed inwardly, so that the portion that is exposed by the separation groove is radially oriented to the adjacent casing member region. The inner offset 099116059 201106584 is moved to form a mounting area that is linearly abutted against the corresponding end face of the stator. Preferably, the separation groove is oriented horizontally and is further oriented in the direction of rotation of the housing member, particularly preferably along a circumference associated with the axis of the rotor or along a tangent to the circumference.

The stator 5 is housed in a motor housing 11 that surrounds the stator from the outside, and the motor housing is composed of two bowl-shell members 12 and 13. The 099116059 12 201106584 housing components are formed from sheet steel stamped and bent, and each have a bowl-shaped section each forming a bearing bracket 在 in the bowl bottom region, wherein the region of the bearing bracket 14 has a disc-shaped profile, The rim includes a circular central socket 15 into which the bearing 16 for the rotor shaft 2 is fixed. The bearing ^ is supported by the bottom of the socket 3 through the coil 29 in this case. An annular bowl wall oriented coaxially with the rotor axis X is connected to a radially outwardly extending conical cover section 17 at its distal end away from the bowl cover formed as a bearing bracket 14, and the path of the cover section The end flange is transformed into a cover flange 1Wb that is at least partially coaxial with the rotor axis X. The cover flange extends over the corresponding position of the housing part 12 "13 relative to the stator 5 and covers the corresponding rounded stator area 10 Edge area. Viewed from the circumferential direction of the covering section 17, a connecting piece 19 is attached to the covering flange 18, and the connecting piece extends parallel to the stator flat area 9 at a corresponding position of the housing parts 12, 13 with respect to the stator $ . The connecting piece rim has a trapezoidal shape including a trapezoidal lower portion extending from the free outer edge of the covering flange 18, a bottom, and a running on the trapezoidal lower bottom and in a vertical direction (ie, along the rotor axis) The direction in which X extends) is a trapezoidal upper base spaced a distance from the free outer edge of the flange 18. The pitch of the two stepped sides of the parallel distribution is greater than the half of the thickness of the stator laminations along the axis of the rotor axis.

The housing member 12 or 13 is provided with four connecting pieces 19. The connecting pieces 19 of the upper housing part in the figure each have a radially outwardly extending press-formed portion 20, wherein the press-formed portion 2 is radially offset from the surrounding area of the connecting piece 19 and the shell The material thickness of the body member u (especially the tab 19) is substantially uniform, and in the selected embodiment the 'material thickness is about one millimeter. Each press-formed portion 20 generally includes the free ends of the tabs and is designed as a double trapezoidal profile. At a corresponding position of the housing part 12 relative to the stator 5, the tab segments comprising the press-formed portion 20 extend in a radial distance from the respective wide faces of the stator flat regions 9, thereby on the surface of the stator A trough-shaped population 21 is formed between the inner surface of the press-formed portion 20, respectively. The other housing member 13 is also provided with a (reverse) connecting piece 19 at a corresponding position relative to the latch 5, and the connecting piece or its connecting piece end is inserted into the π, wherein the connecting pieces 19 are - Upper 'in particular in terms of trapezoidal elongation and corresponding vertical extension production, both with the shell material 12:, part 2. . In fact, each of the housing members 13 extends in "a vertical plane" which is included in the _ plane parallel to a direction along the axis X of the rotor. The solution and arrangement, two housing parts... (especially the free end of the connecting piece of the housing part 13, and the shell 099116059 201106584, the press forming part 2 of the part 12) are horizontally oriented at the mounting position The heavy section 'and the step-by-step cover the flat zone 9 of the stator 5. Further, the housing members 12, 13 are mounted on the corresponding end faces 22 of the stator 5 in the region of the cover section ’ in the mounting position, in a region where the contraction is narrowed. For this purpose, on the + ghost @ μ ^ + , the bottom side of the cover 17 is provided with mounting areas 23, 24 respectively located in the region of the webs 19. The mounting areas are formed from the material of the cover #17 via the separation test 25, and are correspondingly formed with the housing parts η or 13 and the materials are identical. Corresponding to the number of webs 19, each housing part 12, 13 has four bays of this type 'where the housing part 12 situated above has three non-displaceable (ie fixed) The mounting area 23, and a deflectable mounting area 24, the other housing part 13 has only a deflectable mounting area 24. The mounting regions 23 and 24 are cut by the separation groove 25 and pressed radially inwardly to form 'thereby forming a plurality of sections that are horizontally offset with respect to the rotor axis X in the radial direction, wherein 'transmission is made in such a manner The radially inner sections ' of the mounting areas 23 and 24 support the housing parts 12, 13 on the corresponding end faces 22 of the stator 5. The non-removable mounting area 23 has a horizontally extending, in particular, a separating groove 25 extending parallel to the trapezoidal bottom edge of the corresponding web 19, wherein the zone is radially inwardly cut by the separating groove The segment snaps into the conical wall portion of the cover segment 17. The horizontally offset portion of the offsetable mounting area 24 also covers the conical region of segment 099116059 15 201106584, but unlike the non-offset mounting region 23, the segments are formed The angle separating groove 25 is vacated to form the reed 26. The exposed section of the non-removable mounting area 23 extends substantially parallel to the web 19 in a vertical direction, and the reed 26 of the deflectable mounting area 24 is formed from the root area on the covering section to form a About 1 inch. In the case of the production of the corner, it extends obliquely toward the inside in the radial direction. In the illustrated embodiment, the circumferential extent of the exposed section or reed 26 of the mounting zone 23 is approximately equal to the width of the width measured in the same direction as the stator flat zone 9^. One. When the electric motor 1 is installed, after the rotor 3 is inserted into the winding stator 5, a housing member 12, 13 is respectively mounted on one end of the rotor 3 by inserting the rotor shaft 2 through a central bearing bracket hole 27, wherein The housing parts a, 13 enclose the edges of the stator 5 with their covering sections 17 and covering flanges 18, in order to tightly fix the housing parts 12, 13 to the stator 5. The webs 19 of the two housing parts 12, 13 are overlapped, wherein the webs 19 of the lower housing part 13 are embedded in the respective inlets 21. Thereafter, the housing members 12, 13 are supported by respective mounting faces 23 and 24 on respective end faces 22 of the stator 5. The assembly force P of about 1500 Newton meters is applied to the housing member 12 and the crucible 3 along the direction in which the rotor axis X extends. Under the assembly force, the housing members 12 and 13 are oriented in an appropriate manner, in particular. , which makes the bearing bracket hole 27 and the socket 15 for fixing the bearing 16 and the rotor axis χ achieve the exact coaxial orientation of 099116059 16 201106584. Furthermore, the housing members 12 and 13 are oriented in such a way that the axial spacing of the bearings 16 inserted into the socket 15 conforms to a specified size. Thereby, the possible tolerances in the height of the lamination stack of the stator 5 can be compensated for. By supporting the housing parts 12, 13 with the deflectable mounting area 24, the housing parts can be adjusted accordingly with respect to the stator 5. The housing member 12 is first pre-fixed with the non-reversible mounting area 23 of the upper housing member 12, and subsequently, the offset mounting region 24, with the two housing members 12 and 13 oriented, In particular, the cymbal 26, the elasticity achieved by the cymbal 26, causes the corresponding housing component to undergo displacement and/or tilt for overcoming tolerances, during which the reed 26 will more or less further toward the path. Offset to the inside. The housing part 12 is precisely positioned in the plane of the corresponding stator end face 22 by means of three non-reversible mounting areas 23. The fourth deflectable mounting area 24 can be matched to the prescribed plane by possible deformation. In the position in which the housing parts 12 and 13 are mounted, the overlapping webs 19 are welded together, for which purpose the web 19 of the housing part 12 has soldering projections 28 in the region of its press-formed part 20 so that A targeted current transfer is achieved during the implementation of the resistance welding. At this point, the stator 5 is pressed both in the axial direction and in the radial direction. The advantage of the above design is that the stator lamination stack height tolerance can be compensated to further reduce component tolerance requirements. In addition, it is also possible to avoid the inclination of the bearing 16 of the rotor shaft 2, which will have a favorable effect on the noise and service life of 099116059 17 201106584.
