本考案は直流マイクロモータの軸受構造に関するもので
、軸受取付寸法を小さくすることを目的とするものであ
る。[Detailed Description of the Invention] The present invention relates to a bearing structure for a DC micromotor, and its purpose is to reduce the mounting dimensions of the bearing.
最近、直流マイクロモータの薄型化が強く要望されてお
り、その要望に対し従来この種のモータにおける軸受構
造は、第１図ａに示す如く、フレーム１に設けた円筒状
軸受保持部２に軸受３を挿入後、軸受保持部２を絞めて
軸受３を直接固定する構或，あるいは第１図ｂに示す如
く軸受３を凸形に形成し、軸受３を絞めて軸受３をフレ
ーム１に直接固定する構戊が用いられている。Recently, there has been a strong demand for thinner DC micromotors, and in response to this demand, the conventional bearing structure for this type of motor was as shown in Figure 1a. After inserting the bearing 3, the bearing 3 can be fixed directly by tightening the bearing holding part 2, or alternatively, the bearing 3 can be formed into a convex shape as shown in FIG. A fixed structure is used.
しかしながら、前者の構或においては、Ａ寸法が後者の
構或ではＢ寸法が必要となり、薄型化する際の大きな障
害となっていた。However, in the former structure, the A dimension is required, whereas in the latter structure, the B dimension is required, which has been a major obstacle in reducing the thickness.
本考案は上記従来の欠点に鑑みてなされたもので、以下
本考案の一実施例を第２図〜第４図を参照して説明する
。The present invention has been devised in view of the above-mentioned drawbacks of the conventional art, and one embodiment of the present invention will be described below with reference to FIGS. 2 to 4.
図において、１１はメタル軸受で、外周面には軸方向に
複数個の突起１２が一体に設けられている。In the figure, 11 is a metal bearing, and a plurality of protrusions 12 are integrally provided on the outer peripheral surface in the axial direction.
前記突起１２は、その端部が軸受１１の軸方向端面より
若干突出するよう形威している。The protrusion 12 is shaped such that its end portion slightly protrudes from the axial end surface of the bearing 11.
又、軸受１１の軸方向端面にはリング状に形威した凹状
溝１３が形或されている。Further, a ring-shaped concave groove 13 is formed on the axial end face of the bearing 11.
１４は軸受１１が取付けられるフレームで、軸受１１の
突起１２が嵌合する切欠部１５を有する軸受１１と同形
状の開口１６が設けられている。Reference numeral 14 denotes a frame to which the bearing 11 is attached, and is provided with an opening 16 having the same shape as the bearing 11 and having a notch 15 into which the protrusion 12 of the bearing 11 fits.
以上の構威において軸受１１の固定は、フレーム１４の
開口１６に軸受１１を挿入後、軸受１１の突起１２の先
端部を上下方向から絞めることにより、第４図に示す状
態に固定される。In the above structure, the bearing 11 is fixed in the state shown in FIG. 4 by inserting the bearing 11 into the opening 16 of the frame 14 and squeezing the tip of the protrusion 12 of the bearing 11 from above and below.
なお、軸受１１には凹状溝１３が設けられているため、
突起１２の先端を絞めたとき、応力が軸受１１の内径部
に加わるのが防止される。Note that since the bearing 11 is provided with a concave groove 13,
When the tip of the protrusion 12 is squeezed, stress is prevented from being applied to the inner diameter portion of the bearing 11.
以上の説明から明らかなように本考案によれば、軸受の
回転方向の固定は突起により確実になされるとともに、
上下方向の抜けは突起を絞めることにより防止され、し
かも、軸受保持部の上下方向の寸法は突起の先端を絞め
るため、ほぼ軸受の厚さだけで済み、モータの薄型化に
大きく寄与することができる。As is clear from the above description, according to the present invention, the rotational direction of the bearing is securely fixed by the projections, and
Dislodgement in the vertical direction is prevented by constricting the protrusion, and since the vertical dimension of the bearing holding part is constricted at the tip of the protrusion, the thickness of the bearing is sufficient, which greatly contributes to making the motor thinner. can.
