Description
(54) ПЬЕЗОЭЛЕКТРИЧЕСЖИЙ ДАТЧИК(54) PIEZOELECTRIC SENSOR
........ . Изобретение касаетс техники измерени параметров вращающихс деталей машин и механизмов. i Известные многокомпонентные пьезоэлек |Трнческие датчики, предназначенные дл сн тин нескольких компонент ускорени в данной точке вращающейс детали, громоздки и не приемлемы при виброакустических исоледов ни . вращающихс деталей, так как в, этом случае в соответч::твни с методикой раадепенн пространственных колебаний не обходим последовательны съем сигнала с одной точки детали пропорциональным, или продольным, или крутильным, или поперечным колебани м, Цель изобретени - обеспечение возможности поворота датчика вокруг- своей оси и его надежной фиксации. Дл этого предлагаемтзгй датчик содер ,жит накидную резьбовую цангу с внутренней Конической поверхностью и резьбой на наружной поверхности, а наружна поверхность корпуса выполнена в Вще тела вращени ко- ;ничес;сой формы, сопр гаемой с внутренней поверхностью цанги. На чертеже изображена конструкци йред лагаемого датчика. Датч1:к состоит нз чувствительного элемента 1, заключённого в корпусе 2, и резьбовой накидной цанги 3,фиксирующей |кЬр«. |пус с чувствительным элементом в (любом . |положении дл измерени нужной компоненfTbi ускорени . формула изобретений Пьезоэлектрический датчик, состо щий ;из корпуса со встроенным чувствительном элементом, ось чувствительности которого составл ет угол 90 с осью вращени корjnyca датчика, отличающийс тем, J4TO, с целью обеспечени возможности noBo-f Iporra датчика j вокруг своей оси н его надеж|ной ф :ксации, он содержит накидную резьбо-1 вую цангу с внутренней конической поверх ностью , и резьбой на наружной поверхности, |а наружна поверхность корпуса выполнена ID виде тела вращени коничесион|формь{, со пр гаемой с внутренней пов рх1 остью цанги......... The invention relates to a technique for measuring the parameters of rotating parts of machines and mechanisms. i Known multi-component piezoelectric | Tric sensors, designed to remove several components of acceleration at a given point of a rotating part, are bulky and are not acceptable with vibro-acoustic isoleds. rotating parts, since, in this case, according to the :: tedni with the technique of the predetermined spatial oscillations, we do not bypass the sequential removal of the signal from one point of the detail proportional, or longitudinal, or torsional, or transverse oscillations, its axis and its secure fixation. For this purpose, the sensor contains a threaded threaded collet with an inner conical surface and a thread on the outer surface, and the outer surface of the housing is made in all body of rotation, matched to the inner surface of the collet. The drawing shows the construction of a sensor lag sensor. Dat1: k consists of a sensor element 1, enclosed in case 2, and a threaded collet 3, fixing | kf. | Pus with a sensitive element in (any. | position for measuring the desired acceleration component Tbi. Claims: Piezoelectric sensor consisting of; a housing with an integrated sensitive element, the sensitivity axis of which makes an angle of 90 with the axis of rotation of the sensor sensor J4TO, In order to allow the noBo-f Iporra sensor j around its axis to its reliable f: xs, it contains a circular threaded -1 collet with an inner conical surface and a thread on the outer surface, and the outer surface of the body ca executed ID konichesion a rotating body | {formyl, straight from Ai to the inner dressing PX1 awn collet.
