【０００１】
【産業上の利用分野】
本発明は小型モータの製造方法に関するものである。
【０００２】
【従来の技術】
以下、従来の小型モータについて図を参照しながら説明する。図２は従来の小型モータの油つぼに含油繊維材を封入する断面図を示すものである。図２において、１は小型モータのフレーム、２はフレーム１の内側に設けられた含油メタルからなる軸受、３は軸受２を押圧する押さえリング、４は押さえリング３を介して軸受２を押圧するばね、５はフレーム１の嵌合部でかしめらればね４を固定するフレームカバー、６は油つぼ、７はフレーム１に設けられ穴である。
【０００３】
このように構成された従来の小型モータの油つぼ６に含油繊維材を封入する方法について説明する。図２に示すように、軸受２の上部には、ばね４の内周側の周面をマスキングするマスキング治具８を挿入すると共に、フレーム１の穴７より油つぼ６に含油繊維材９を封入する封入ノズル１０を挿入させ、この状態で含油繊維材９を封入ノズル１０の先端より含油繊維材９を矢印１１方向に封入する。図３は従来の小型モータの油つぼに含油繊維材を封入した断面図である。図３において、１はフレーム、２は軸受、６は油つぼ、７は穴、９は油つぼ６に封入された含油繊維材である。

【０００８】
【作用】
この製造方法によって、ばねの隙間からの含油繊維材のはみ出しが防止され、軸受に含油繊維材を安定に接触させることができる。
【０００９】
【実施例】
以下、本発明の一実施例について図面を参照しながら説明する。図１は本発明の一実施例における小型モータの油つぼに含油繊維材を封入する断面図である。図１において、１２は小型モータのフレーム、１３はフレーム１２の内側に設けられた含油メタルからなる軸受、１４は軸受１３を押圧する押さえリング、１５は押さえリング１４を介して軸受１３を押圧するばね、１６はフレーム１２の嵌合部でかしめらればね１５を固定するフレームカバー、１７は油つぼ、１８はフレーム１２に設けられた穴である。
【００１０】
このように構成された本実施例の小型モータの油つぼ１７に含油繊維材を封入する方法について説明する。図１に示すように、軸受１３の上部に変形可能なシリコンパイプ等からなるマスキング治具１９を挿入すると共に、マスキング治具１９を矢印２０方向に押圧して、マスキング治具１９の外周面よりばね１５の内周壁面を押圧する。さらに、油つぼ１７に含油繊維材２１を封入する封入ノズル２２をフレーム１２に設けられた穴１８に挿
入し、封入ノズル２２の先端の側面にはノズル孔２３が矢印２４方向に封入するように設けられており、このノズル孔２３より含油繊維材２１を矢印２４方向に封入して、軸受１３の外周面に含油繊維材２１を封入する工程を有している。
【００１１】
このように小型モータの油つぼ１７に含油繊維材２１を封入した後、マスキング治具１９と封入ノズル２２とを取り外し、軸受１３の中心の貫通孔にロータを有するシャフトを挿入する。
【００１２】

FIG. 2 is a cross-sectional view of a conventional small motor in which an oil-containing fiber material is sealed in an oil pot. In FIG. 2, 1 is a frame of a small motor, 2 is a bearing made of an oil-impregnated metal provided inside the frame 1, 3 is a press ring for pressing the bearing 2, and 4 is a press for the bearing 2 via a press ring 3. A spring 5 is a frame cover that is caulked at a fitting portion of the frame 1 to fix the spring 4, 6 is an oil pot, and 7 is a hole provided in the frame 1.
[0003]
A method of enclosing an oil-containing fiber material in the oil crucible 6 of the conventional small motor configured as described above will be described. As shown in FIG. 2, a masking jig 8 for masking the inner peripheral surface of the spring 4 is inserted into the upper part of the bearing 2, and the oil-impregnated fiber material 9 is inserted into the oil crucible 6 through the hole 7 of the frame 1. The sealing nozzle 10 to be sealed is inserted, and the oil-containing fiber material 9 is sealed from the tip of the sealing nozzle 10 in the direction of the arrow 11 in this state. FIG. 3 is a cross-sectional view in which an oil-containing fiber material is sealed in an oil pot of a conventional small motor. In FIG. 3, 1 is a frame, 2 is a bearing, 6 is an oil pot, 7 is a hole, and 9 is an oil-containing fiber material sealed in the oil pot 6.
