This invention relates to a gear measuring device that measures the outer diameter of each journal and corrects the measured value.
（ｂ）従来技術と問題点 最初に、従来のギヤ測定装置の構成図を第２図に示す。(b) Conventional technology and problems First, a configuration diagram of a conventional gear measuring device is shown in FIG.
第２図の１はギヤ、２と３はセンタ、４はマスタギヤ、

5 is a drive motor, 6 is a gear head, 7 is a gear unit,
8 is a proximity switch, 9A is a detector, 9B is an amplifier, 9C
is an arithmetic unit.
被測定物のギヤ１は両端をセンタ２とセンタ３で保持さ
れ、基準のマスタギヤ４とかみ合わせて回転させられる
。回転速度は、駆動モータ５と減速用のギヤヘッド６で
１歯あたり約０．１〜０．２秒程度にする。A gear 1, which is an object to be measured, is held at both ends by centers 2 and 3, and is rotated while meshing with a reference master gear 4. The rotational speed of the drive motor 5 and the gear head 6 for deceleration is set to about 0.1 to 0.2 seconds per tooth.
マスターギヤ４が回転するとギヤ１とかみ合い、歯車ユ
ニット７がかみ合い状況に応して変動する。When the master gear 4 rotates, it meshes with the gear 1, and the gear unit 7 changes depending on the meshing situation.
これを検出器９Ａで検出し、増幅器９Ｂ、演算器９Ｃを
通してそれぞれ中心間距離、歯振れ、打痕の測定値が得
られる。This is detected by the detector 9A, and the measured values of the distance between centers, tooth runout, and dents are obtained through the amplifier 9B and the arithmetic unit 9C.
近接スイッチ８は演算をするときの一歯あたりのタイミ
ングを得るためのものである。The proximity switch 8 is used to obtain the timing per tooth when performing calculations.

・(3) The problem with Figures 2 and 3 is that the measured values are based on the center hole, so the accuracy of the center hole is poor, and the center hole is not accurate.
If dirt or dust adheres to 3, it will cause a measurement error.
また、ギヤ１は組み立てられ、ジャーナル軸基準で回転
させられるため、仮のセンタ穴基準では実用的でないし
、精度の高い測定とはいえないということである。Furthermore, since the gear 1 is assembled and rotated with reference to the journal axis, using a temporary center hole reference is not practical and cannot be said to be a highly accurate measurement.
（Ｃ）発明の目的
この発明は、測定値をセンタ基準から、ジャーナル基準
にして従来技術の問題を解決するとともに、ジャーナル
外径が変化しても外径を補正し、ジャーナル軸基準の中
心間距離、歯振れ、打痕を測定することを目的とする。(C) Purpose of the Invention This invention solves the problems of the prior art by changing the measured value from the center reference to the journal reference, and also corrects the outer diameter even if the outer diameter of the journal changes, and the distance between the centers of the journal axis reference. The purpose is to measure distance, tooth runout, and dents.
