モータの軽量化、特に自動車分野における軽量化要求は厳しくなってきており 、モータケースの樹脂化もさかんに検討されるようになった。 The demand for weight reduction of motors, especially in the automobile field, has become stricter, and the use of resin in the motor case has also been studied extensively.
【０００３】 以下、上述の従来のモータケースについて図３，図４を参照しながら説明する 。The above-mentioned conventional motor case will be described below with reference to FIGS. 3 and 4.
【０００４】 図３に示すように、ステータ４とケース１のスキマに接着剤５を注入しステー タ４をケース１と固定、また図４に示すようにケース１にステータ４を挿入後、 予圧バネ６を介してカバー７を固定しステータ４の動きを防止していた。As shown in FIG. 3, adhesive 5 is injected into the gap between the stator 4 and the case 1 to fix the stator 4 to the case 1, and after the stator 4 is inserted into the case 1 as shown in FIG. The cover 7 is fixed via the spring 6 to prevent the stator 4 from moving.
【０００５】[0005]
このような従来のモータケースでは、接着剤を使用する場合においてはその作 業性，量，ケースとモータ出力軸のケースに対する同軸度確保，接着剤の耐熱性 ，耐寒性に難を有しており、予圧バネ使用時においては、前記同軸度確保，予圧 バネ自体余分な材料であることが難とされていた。 In such a conventional motor case, when an adhesive is used, it has problems in workability and quantity, securing the coaxiality of the case and the motor output shaft with respect to the case, heat resistance of the adhesive, and cold resistance. However, when the preload spring is used, it is difficult to secure the coaxiality and to use the preload spring as an extra material.
【０００６】 本考案は上記課題を解決するもので、ケースの形状の工夫のみでステータの動 き止めを確実にし、ステータのケースへの挿入性を改良するモータケースを提供 するものである。The present invention solves the above-described problems, and provides a motor case that secures the movement of the stator only by devising the shape of the case and improves the insertability of the stator into the case.

本考案は上記目的を達成するために、ステータ外径の凹部に対応した凸部を樹 脂ケース内径に設け、かつ前記ケース内径に複数の微小凸部を設け、前記ケース 内径はモータ常温時ステータ内径より小とし、モータが使用される最高環境温度 とモータ運転による温度上昇を加えた温度でケースを予熱した時、ステータ外径 より大とし微小凸部内径は小となるよう設定してなるものである。 In order to achieve the above-mentioned object, the present invention provides a convex portion corresponding to the concave portion of the stator outer diameter on the inner diameter of the resin case, and a plurality of minute convex portions on the inner diameter of the case. It is smaller than the inner diameter, and when the case is preheated at the maximum environmental temperature in which the motor is used and the temperature increased by the motor operation, it is set to be larger than the outer diameter of the stator and smaller than the inner diameter of the small convex portion.

本考案は上記した構成により、モータケース内径の工夫のみによりモータの環 境温度を含めた使用状態においても何らの部品を追加使用することなくケース内 でのステータの動きを防止し、モータコイルの断線やステータの動きによる振動 ，ノイズが防止できるものである。また、ステータのケースへの挿入性も比較的 低温域のケースの予熱で簡単にできる。 With the above-mentioned configuration, the present invention prevents the movement of the stator in the case by using only the inner diameter of the motor case and prevents the movement of the stator in the case even when the motor is in use including the ambient temperature. Vibration and noise due to wire breakage and stator movement can be prevented. Also, the insertability of the stator into the case can be simplified by preheating the case in a relatively low temperature range.
【０００９】[0009]
以下、本考案の一実施例について図１，図２を参照しながら説明する。 An embodiment of the present invention will be described below with reference to FIGS.
【００１０】 図に示すように、ケース１の内径はステータ４の凹部３ａに対応する凸部３を 有し、複数の微小凸部２がケース１の内径に設けられている。前記ケース１の内 径はモータ常温時はステータ４の外径より小さく、最高使用環境温度とモータ運 転による温度上昇を加えた温度でケース１を予熱した時ステータ４の内径より大 きく、ケース１の微小凸部２の内径は小さくなるよう設定されている。As shown in the figure, the inner diameter of the case 1 has a convex portion 3 corresponding to the concave portion 3 a of the stator 4, and a plurality of minute convex portions 2 are provided on the inner diameter of the case 1. The inner diameter of the case 1 is smaller than the outer diameter of the stator 4 when the motor is at room temperature, and is larger than the inner diameter of the stator 4 when the case 1 is preheated at a temperature including the maximum operating environment temperature and the temperature rise caused by the motor operation. The inner diameter of the small convex portion 2 of No. 1 is set to be small.
【００１１】 このように本考案の実施例のモータケースによれば、最悪環境温度でのモータ 使用時においてもステータ４のケース１内でのあらゆる方向の動きは防止できる 。As described above, according to the motor case of the embodiment of the present invention, the movement of the stator 4 in all directions in the case 1 can be prevented even when the motor is used at the worst environmental temperature.
【００１２】[0012]
以上の実施例から明らかなように、本考案によれば凸部により回転方向の動き が防止でき、ケースの内径とケース内径に設けられた微小凸部の寸法設定のみに より、モータの最悪使用環境温度での運転でも接着剤や予圧バネの使用を必要と せずステータとケースの固定ができ、動きによるモータコイルの断線，振動，ノ イズ等の不具合発生を防止できる。また、樹脂ケースに過大な応力をかけること なく必要かつ十分なステータの保持力が得られる。また、ステータの挿入におい ても比較的低温領域でケースの予熱が設定でき、スムーズにステータが挿入でき る。 As is apparent from the above-described embodiments, according to the present invention, the movement in the rotation direction can be prevented by the convex portion, and only by setting the dimension of the case inner diameter and the minute convex portion provided on the case inner diameter, the worst use of the motor is possible. Even when operating at ambient temperature, the stator and case can be fixed without the need for adhesives or preload springs, and problems such as motor coil disconnection, vibration, and noise due to movement can be prevented. Further, the necessary and sufficient stator holding force can be obtained without applying excessive stress to the resin case. Also, when inserting the stator, the case can be preheated in a relatively low temperature range, and the stator can be inserted smoothly.
