Description
【考案の詳細な説明】 本考案は回転部品取付装置に関する。[Detailed explanation of the idea] The present invention relates to a rotating component mounting device.
従来アーム又はレバーに回転アームをつけその回転アー
ム上に回転体を取付は回転アームを前記アーム又はレニ
く−に対して自由に回転ア゛ニムの支点を中心に回転で
きるようにする回転部品取付装置にあっては、取付にあ
たっては回転アームの支点となる部分にシャフトを立て
かつ抜は止め部材を使用して抜は止めし筐た回転部品の
中心にさらに別のシャフトを立てなければならなかった
ので、使用部品が多く取付がめんどうであった。Conventionally, a rotary arm is attached to an arm or a lever, and a rotary body is mounted on the rotary arm.The rotary part is attached so that the rotary arm can freely rotate around the fulcrum of the rotary arm relative to the arm or lever. When installing the device, the shaft must be erected at the fulcrum of the rotating arm, and a member must be used to prevent it from being pulled out, and another shaft must be erected at the center of the rotating component in the housing. Therefore, many parts were used and installation was troublesome.
そこで本考案の目的は上記した従来技術のシャフトを2
本使用せずに一本のシャフトにて取付は特に抜は止め部
材を必要としないようにした回転部品取付装置を提供す
ることにある。Therefore, the purpose of this invention is to replace the shaft of the prior art described above with two
The object of the present invention is to provide a rotating component mounting device that does not require a removal-preventing member and can be mounted using a single shaft without using it.
以下本考案を図面に示す実施例によシ説明しよう。The present invention will be explained below with reference to embodiments shown in the drawings.
図面はカセットテープテープレコーダのアイドラの取付
けにして、1はシャフト、2は回転体であるアイドラ、
3は回転アーム、4はアーム、5はシャーシである。The drawing shows the installation of the idler of a cassette tape recorder, where 1 is the shaft, 2 is the idler which is a rotating body,
3 is a rotating arm, 4 is an arm, and 5 is a chassis.
シャフト1を回転体2の孔2aを通し、回転アーム3の
孔3aに圧入する。The shaft 1 is passed through the hole 2a of the rotating body 2 and press-fitted into the hole 3a of the rotating arm 3.
その時回転アーム3のボス3bをアーム4の支点用の孔
4aに挿入した状態で圧入し、回転アーム3はアーム4
とシャーシ5に挾1れた状態で位置出しされ回転体2と
のスキマaと回転体2のスラストガタbをa)bとし、
回転したときにアーム3のボス3bと回転体2とが当た
らないようにする。At this time, the boss 3b of the rotary arm 3 is inserted into the fulcrum hole 4a of the arm 4 and press-fitted, and the rotary arm 3 is inserted into the fulcrum hole 4a of the arm 4.
The clearance a between the rotating body 2 and the thrust backlash b of the rotating body 2 which is positioned in a state where it is held in the chassis 5 is a) and b,
The boss 3b of the arm 3 and the rotating body 2 are prevented from coming into contact with each other when rotated.
又アセンブリ状態でアセンブリ状態が保たれるようにa
のスキ÷はアーム4の厚さよりも小さくする。Also, so that the assembly state is maintained in the assembly state, a
The gap ÷ should be smaller than the thickness of the arm 4.
またボス3bを回転体2の外径より内側に設けであるた
めに、アーム4は回転アーム3と回転体2によって挾1
へ特別抜は止めの工夫を必要としない。In addition, since the boss 3b is provided inside the outer diameter of the rotary body 2, the arm 4 can be attached to the clamp 1 by the rotary arm 3 and the rotary body 2.
There is no need for any special measures to stop the special removal.
このように本考案は回転部品の取付に釦いて、シャーシ

2と前記シャフト1のスキマbを前記回転アーム3のボ
ス3bと前記回転体2のスキマaより小さくし前記回転
アーム3のボス3bを前記回転体2の外径より内側に設
けたことにより、回転アーム3の取付に格別取付後は止
め部材を必要とせず簡単に取付ができる効果を有するも
のである。In this way, the present invention focuses on the installation of rotating parts, and includes the chassis 5, the arm 4 attached to the chassis 5, and the boss 3b inserted into the hole 4a of the arm 4 so as to be rotatable. A rotary arm 3 positioned in the thickness direction by the chassis 5, and a hole 2 facing the hole 3a of the rotary arm 3.
a rotary body 2 having a diameter of
The thickness of the arm 4 is made larger than the clearance a between the boss 3b of the rotating arm 3 and the rotating body 2, and the clearance b between the rotating body 2 and the shaft 1 is made thicker than the clearance a between the boss 3b of the rotating arm 3 and the rotating body. 2, and the boss 3b of the rotary arm 3 is provided inside the outer diameter of the rotary body 2, so that the rotary arm 3 can be easily mounted without requiring a stopper member after installation. It has the effect that it can.
このことは従来のこの種の回動回転物を取付けろ方法を
簡便にし、その経済的効果は犬なるものがあり、工業的
価値は大きなものがある。This simplifies the conventional method of mounting this type of rotary object, has significant economic effects, and has great industrial value.
