Description

Предметом изобретени   вл етс  кольцевой динамометр с проволочным датчиком.The subject of the invention is a ring dynamometer with a wire sensor.

В известных кольцевых динамометрах датчики выполнены в виде дв-ух нат нутых по диаметру кольца струн во взаимно перпендикул рных направлени х.In the known ring dynamometers, the sensors are made in the form of two-stringed strings with a diameter of a ring in mutually perpendicular directions.

Под действием силы кольцо деформируетс  и струны мен ют свой строй, т. е. частоту колебаний. Дл  измерени  частот колебаний струн требзетс  сложна  электронна  аппаратура .Under the action of a force, the ring is deformed and the strings change their mode, i.e., the oscillation frequency. Complicated electronic equipment is required to measure the vibration frequencies of strings.

В предлагаемом динамометре этот недостаток устранен. Элементы его датчика соединены по обычной мостовой схеме, в одну диагональ которой включен источник тока, а в другую указательный прибор.In the proposed dynamometer, this disadvantage is eliminated. The elements of its sensor are connected in a conventional bridge circuit, in one diagonal of which the current source is included, and in another pointing device.

На чертеже приведена принципиальна  схема динамометра.The drawing shows a schematic diagram of a dynamometer.

Датчик выполнен из тонкой изолированной проволоки в виде замкнутого витка, наклеенного на внешнюю или внутреннюю поверхность кольца / концентрично его центру. При деформации лольца от действи  на него силы Р у двух участков датчика «i и а.з кривизна увеличиваетс , а у двух других as и а.,-The sensor is made of thin insulated wire in the form of a closed loop, glued to the outer or inner surface of the ring / concentric with its center. During deformation of the lob from the effect of force P on it, the two portions of the sensor "i and a.z" increase in curvature, and in the other two as and a., -

Изменение кривизны участков датчика ведет к изменению сопротивлени  этих участков .is reduced (the deformed state of the ring is depicted in the figure by a dotted line). A change in the curvature of the sensor sections leads to a change in the resistance of these sections.

К точкам с нулевой деформацией AI и АЗ, а также Ло и Аз. подключены соответственно источник тока и гальванометр. Измер ема  сила Р определ етс  по показанию гальванометра , предварительно протарнрованного в единицах силы.To points with zero deformation AI and AZ, as well as Lo and AZ. connected, respectively, the current source and galvanometer. The measured force P is determined by the indication of a galvanometer previously stained in units of force.
