Description
【０００１】[0001]
本考案は、小形回転電機のリング状マグネットをフレームに固定する装置に関 する。 The present invention relates to a device for fixing a ring magnet of a small rotating electric machine to a frame.
【０００２】[0002]
従来、中空円筒状のフレームの内周にリング状のマグネットを接着剤を使用せ ず、機械的に固定する装置として、マグネットの端面とエンドブラケットの内面 とに設けた凹部にそれぞれ係合し、軸方向に反対方向に突出する凸部を備えたリ ング状の板バネを、マグネットとエンドブラケットの間に挟むようにしたものが 開示されている（例えば、実公昭３９−３４１５号公報）。 Conventionally, as a device that mechanically fixes a ring-shaped magnet to the inner circumference of a hollow cylindrical frame without using an adhesive, it engages with recesses provided on the end surface of the magnet and the inner surface of the end bracket, respectively. It is disclosed that a ring-shaped leaf spring having a protrusion protruding in the opposite direction to the axial direction is sandwiched between a magnet and an end bracket (for example, Japanese Utility Model Publication No. 39-3415).
【０００３】[0003]
ところが、上記構成では、エンドブラケットおよびマグネットに係合用の凹部 を設ける必要があり、部品の加工に多くの時間がかかるという欠点があった。 本考案は、部品の加工やマグネットの固定作業が簡単なマグネットの固定装置 を提供することを目的とするものである。 However, in the above-mentioned configuration, there is a drawback in that it is necessary to provide recesses for engagement in the end bracket and the magnet, and it takes a lot of time to process parts. An object of the present invention is to provide a magnet fixing device that facilitates the processing of parts and the magnet fixing work.
【０００４】[0004]
本考案は、中空円筒状のフレームの内周に段付部を設け、リング状のマグネッ トの一方の端面を前記段付部に突き当てて固定するマグネットの固定装置におい て、前記フレームの内側に先端がそれぞれ鋭く尖った軸方向爪および放射状に突 出するラジアル爪を設けたリング状の板バネを装入し、前記軸方向爪を前記マグ ネットの他方の端面に突き当て、前記ラジアル爪を前記フレームの内周に食い込 ませたものである。 The present invention is a magnet fixing device in which a stepped portion is provided on the inner circumference of a hollow cylindrical frame, and one end face of a ring-shaped magnet is abutted and fixed to the stepped portion. Insert a ring-shaped leaf spring provided with axial claws with sharp tips and radial claws protruding radially, and abut the axial claws on the other end surface of the magnet. Is the one that bites into the inner circumference of the frame.
【０００５】[0005]
板バネをフレームの内周に装入する場合、ラジアル爪を内側に撓ませてフレー ム１の内周に押し込み、マグネットに突き当てると、軸方向爪はマグネットの端 面に食い込むと共に、ラジアル爪はその弾性により、フレームの内周に食い込む ので、マグネットはフレームの内周で板バネを介して軸方向および円周方向の動 きが止められる。 When loading a leaf spring on the inner circumference of the frame, bend the radial claws inward, push them into the inner circumference of the frame 1, and hit them against the magnet. Because of its elasticity, it digs into the inner circumference of the frame, so that the magnet is prevented from moving axially and circumferentially through the leaf spring at the inner circumference of the frame.
【０００６】[0006]
本考案を図に示す実施例について説明する。 図１は本考案の実施例を示す側断面図で、中空円筒状のフレーム１の内周に段 付部１１を設け、リング状のマグネット２の一方の端面２１の角部２２を段付部 １１に押し付けてフレーム１の内周にマグネット２を装入してある。マグネット ２の他方の端面２３側のフレーム１の内側には、リング状のバネ鋼からなる板バ ネ３を装入してある。板バネ３のマグネット２に対向する軸方向には先端が鋭く 尖った複数の軸方向爪４を突出させ、外周には放射状に先端が鋭く尖った複数の ラジアル爪５を設け、フレーム１の内周に装入する前はフレームの内径より大き い内径まで突出するようにしてある。 板バネ３をフレーム１の内周に装入する場合、ラジアル爪５を内側に撓ませて フレーム１の内周に押し込み、マグネット２に突き当てる。そうすると、軸方向 爪４はマグネット２の端面２３に食い込むと共に、ラジアル爪５はその弾性によ り、フレーム１の内周に食い込む。 したがって、マグネット２はフレーム１の内周で板バネ３を介して軸方向およ び円周方向の動きが止められ、固定される。 The present invention will be described with reference to the embodiments shown in the drawings. FIG. 1 is a side sectional view showing an embodiment of the present invention, in which a step portion 11 is provided on the inner circumference of a hollow cylindrical frame 1 and a corner portion 22 of one end face 21 of a ring-shaped magnet 2 is stepped portion. The magnet 2 is inserted into the inner periphery of the frame 1 by pressing it against 11. Inside the frame 1 on the side of the other end face 23 of the magnet 2, a plate-shaped panel 3 made of ring-shaped spring steel is inserted. A plurality of axial claws 4 having sharp tips in the axial direction facing the magnets 2 of the leaf spring 3 are projected, and a plurality of radial claws 5 having sharp tips in a radial shape are provided on the outer circumference, so that the inside of the frame 1 Before being inserted into the circumference, it projects to an inner diameter larger than the inner diameter of the frame. When the leaf spring 3 is inserted into the inner circumference of the frame 1, the radial claw 5 is bent inward, pushed into the inner circumference of the frame 1, and abutted against the magnet 2. Then, the axial claw 4 bites into the end surface 23 of the magnet 2, and the radial claw 5 bites into the inner periphery of the frame 1 due to its elasticity. Therefore, the magnet 2 is fixed in the inner circumference of the frame 1 by the leaf spring 3 so as to stop the movement in the axial direction and the circumferential direction.

以上述べたように、本考案によれば、板バネに設けた先端が鋭く尖った軸方向 爪およびラジアル爪によってマグネットがフレームに固定されるので、マグネッ トおよびブラケットなどに係合部を加工する必要がなく、加工作業や組立作業が 簡単になるとともに、部品点数も削減できるなどの効果がある。 As described above, according to the present invention, since the magnet is fixed to the frame by the axial claw and the radial claw provided with the sharp tip on the leaf spring, the engaging part is processed on the magnet and the bracket. There is no need, and the processing and assembly work is simplified, and the number of parts can be reduced.
