Изобретение относитс к измерительной технике и может быть использовано дл измерени абсолютной и относительной скоростей вращени двух объектов.The invention relates to a measurement technique and can be used to measure the absolute and relative rotational speeds of two objects.

По основному авт. св. № 693258 известно устройство дл контрол синхронности вращени двух объектов, содержащее статор и ротор, выполненные в виде параболоидов вращени , внутренние поверхности которых разделены на отражающие и поа ощающие свет секторы. Статор и ротор кинематически св заны, с контролируемыми объектами. В фокусе статора расположен источник света, а в фокусе ротора - фотоприемник, который подключен к блоку определени рассогласовани скоростей вращени 1.According to the main author. St. No. 693258, a device is known for controlling the synchronism of rotation of two objects, comprising a stator and a rotor, made in the form of rotation paraboloids, the inner surfaces of which are divided into reflecting and supporting light sectors. The stator and rotor are kinematically associated with controlled objects. A light source is located at the focus of the stator, and a photodetector is located at the rotor focus, which is connected to the rotational speed difference 1.

Недостатком этого устройства вл етс то, что оно позвол ет контролировать только относительную скорость вращени и при использовании его в системах с регулируемым приводом необходимы .дополнительные датчики абсолютной скорости вращени объектов.A disadvantage of this device is that it allows you to monitor only the relative speed of rotation and, when used in systems with adjustable drive, additional sensors are needed for the absolute speed of rotation of objects.

Цель изобретени - расширение функциональных возможностей устройства за счет получени возможности измерени абсолютных скоростей вращени объектов.The purpose of the invention is to expand the functionality of the device by making it possible to measure the absolute speeds of rotation of objects.

Поставленна цель достигаетс тем, что в устройство введен амплитудный селектор и блок регистрации абсолютной скорости, а между статором и ротором установлен диск с прорез ми, суммарна площадь которых не равна суммарной площади отражающих секторов статора, причем статор выполнен в центральной части с круговой зоной полного отражени , а диаметр диска равен диаметру зоны полного отражени статора, при этом фотоприемник соединенThe goal is achieved by introducing an amplitude selector and an absolute speed detection unit into the device, and a slotted disk is installed between the stator and the rotor, the total area of which is not equal to the total area of the reflector sectors of the stator, and the stator is made in the central part with a circular area of full reflection and the diameter of the disk is equal to the diameter of the stator complete reflection zone, while the photodetector is connected

The separator disk 9 (Fig. 3) is divided into light absorbing sectors 15 and light transmitting sectors 16. The rotor (Fig. 4) divided on absorbing 17 and reflecting 18 sectors. The device works as follows. The rays from the light source 3 are reflected from the sectors 13 of the stator 2 to the rotor 4 and, reflected from the sectors 18 of the rotor 4, fall on the photodetector 5.
