本考案は固定用カラー、特に、転がり軸受を軸
に固定する場合なでにおいて、小さなスペースで
使用できるようにするとともに固定用カラーによ
る固定力が十分になるようにするものである。[Detailed description of the invention] [Field of application] The present invention is a fixing collar, especially when fixing a rolling bearing to a shaft, so that it can be used in a small space and the fixing force of the fixing collar is sufficient. It is to make it happen.
駆動源と伝動回転する回転軸は、通常、転がり
軸受によつて支持されており、第５図のような使
用態様が多い。
The rotating shaft that rotates in transmission with the drive source is usually supported by a rolling bearing, and is often used in the manner shown in FIG. 5.
駆動モータＭの出力軸ＤとカツプリングＣによ
つて伝動状態に連結された回転軸Ｋが転がり軸受
Ｂによつて回転自在に支持される構成である。最
近では、装置の小型化の要求が高く、この転がり
軸受ＢとカツプリングＣとの間隔を大きくとれな
い。そこで、従来は、転がり軸受Ｂを固定するた
めに、同図に示すようにカツプリングＣと転がり
軸受Ｂとの間に転がり軸受Ｂの内輪を押すための
環状のスペーサＳと環状体１とを介装している。 In this configuration, an output shaft D of a drive motor M and a rotating shaft K, which are connected in a transmission state through a coupling C, are rotatably supported by a rolling bearing B. Recently, there is a strong demand for miniaturization of devices, and it is not possible to maintain a large distance between the rolling bearing B and the coupling C. Therefore, conventionally, in order to fix the rolling bearing B, an annular spacer S and an annular body 1 for pushing the inner ring of the rolling bearing B are interposed between the coupling C and the rolling bearing B, as shown in the figure. I am wearing it.
この環状体１は回転軸Ｋのネジ部Ｎとネジ嵌合
するようになつており、転がり軸受Ｂとの間にス
ペーサＳを挿入して環状体１を締付けると、転が

る。そして、この環状体１に具備させた固定ネジ
１１を締め込むと、環状体１はその位置に固定さ
れる。 This annular body 1 is adapted to be screwed into a threaded portion N of a rotating shaft K, and when a spacer S is inserted between the rolling bearing B and the annular body 1 is tightened, the rolling bearing B is placed in a predetermined position. is pushed in and fixed. When the fixing screw 11 provided on the annular body 1 is tightened, the annular body 1 is fixed at that position.
ところが、この従来のものでは、回転軸Ｋが正
逆回転を繰り返す場合や伝達トルクが大きい場合
等においては、環状体１の固定力が不十分で緩み
易いと言う問題がある。 However, in this conventional device, there is a problem in that the fixing force of the annular body 1 is insufficient and the annular body 1 easily loosens when the rotating shaft K repeats forward and reverse rotations or when the transmitted torque is large.
これは、回転軸Ｋのネジ部と環状体１のネジ部
との間にバツクラツシユがあるからである。 This is because there is a backlash between the threaded portion of the rotating shaft K and the threaded portion of the annular body 1.
このバツクラツシユに相当する間隙が環状体１
の雌ネジ部とネジ部Ｎとの間に生じるからであ
り、雄ネジ部と雌ネジ部との接触面積が少いから
である。 The gap corresponding to this backlash is the annular body 1.
This is because the contact area between the male threaded portion and the female threaded portion is small.
本考案は、このような、『回転軸Ｋを回転自在

ことをその技術的課題とする。
The present invention aims to reduce the contact area between the threaded part N provided on the rotating shaft K and the threaded part of the fixing collar in such a "fixing collar of a rolling bearing B etc. that rotatably supports the rotating shaft K". The technical challenge is to make it possible to make it larger.

この結果、ネジ部Ｎと環状体１の雌ネジ部との接
触面積が大きくなる。 In this fixed state, a minute gap corresponding to a backlash is created between the female threaded portion of the annular body 1 and the threaded portion N in the thread. Therefore, the tightening bolt 1 provided on this annular body 1
When bolts 3 and 13 are tightened, these bolts are inserted through the slit assembly 10, and each arcuate portion of the annular body 1 is made elastically movable in the radial direction by the slit assembly 10. The diameter of the annular body 1 is reduced. As a result, the threads of the female threaded portion of the annular body 1 bite into the threads of the threaded portion N, thereby eliminating the backlash.
As a result, the contact area between the threaded portion N and the female threaded portion of the annular body 1 increases.

定用カラーが緩みにくいものとなる。 In the final installed state, the threads of the female threaded part of the annular body 1 bite into the threads of the threaded part N, and the backlash is eliminated. Since the contact area with the fixing collar is larger, the fixing collar is less likely to loosen compared to the conventional ones mentioned above.
