Изобретение относитс к области измерительной техники, а именно к бесконтактным способам измерени диаметров преимущественно крупногабаритных деталей.The invention relates to the field of measurement technology, namely to non-contact methods for measuring the diameters of mainly large-sized parts.
Известен способ бесконтактного измерени диаметров вращающихс деталей по центральному углу и хорде посто нной длины, ст гивающей данный угол 1. Он заключаетс в том, что на поверхность вращающейс детали нанос т сигнал и измер ют центральный угол, заключенный между двум считывающими головками, расположенными на заданном рассто нии одна от другой, при прохождении сигнала. По заданному рассто нию (посто нной хорде) и центральному углу определ ют длину окружности и соответственно диаметр детали.The known method of contactless measurement of the diameters of rotating parts at a central angle and a chord of constant length, tightening this angle 1. It consists of applying a signal to the surface of the rotating part and measuring the central angle between two reading heads located on a given distance from one another, with the passage of the signal. For a given distance (constant chord) and central angle, the circumference and, accordingly, the diameter of the part are determined.
Недостатком известного способа вл етс значительна погрешность измерени , обусловленна ошибкой измерени центрального угла.The disadvantage of this method is a significant measurement error due to the measurement error of the central angle.
В цел х повыщени точности измерени по предлагаемому способу определ ют врем перемещени сигнала между головками, затем по заданному рассто нию и времени-скорость движени поверхности, и длину окружности наход т, интегриру скорость в течение периода вращени детали.In order to improve the measurement accuracy of the proposed method, the time of moving the signal between the heads is determined, then, over a specified distance and time-speed of movement of the surface, and the circumference is found by integrating the speed during the period of rotation of the part.

С помощью записывающей головки 1 на поверхность измер емой вращающейс детали 2 нанос т последовательность сигналов. С помощью считывающей головки 3, расположенной па заданном рассто нии от головки 1, нанесенную последовательность сигналов считывают , и определ ют врем перемещени Using a recording head 1, a sequence of signals is applied to the surface of the rotating part 2 to be measured. Using a read head 3 located at a predetermined distance from the head 1, the applied signal sequence is read and the time of movement is determined
