Изобретение относитс  к способам определени  цетра т жести тел вращени  и может быть использовано дл  определени  центра т жести, напри- , мер, бойков автоматов безопасности паровых и газовых турбин.The invention relates to methods for determining the center of gravity of a body of revolution and can be used to determine the center of gravity of, for example, measures, hammer heads of safety devices of steam and gas turbines.

Известен способ определени  центра т жести тел вращени , заключающийс  в фиксировании равновесного JQ состо ни  исследуемого тела, закрепленного на нескольких опорах, и измерении давлени  на одну иэ них 1 .The known method of determining the center of gravity of the body of revolution consists in fixing the equilibrium JQ state of the body under study fixed on several supports and measuring the pressure on one of them 1.

Известен также способ определе- 15 ни  центра т жести тел вращени  путем закреплени  образца в держателе и перемещени  держател  2,There is also known a method for determining the center of gravity of a body of revolution by fixing the sample in the holder and moving the holder 2,

Данный способ  вл етс  наибол,ее близким к Изобретению по техничёс- 20 кой сущности и достигаемому результату .This method is the most close to the invention in terms of its technical essence and the achieved result.

Цель изобретени  - повышение точности измерени .The purpose of the invention is to improve the measurement accuracy.

Дл  этого используют держатель, 25 снабженный датчиками давлени , / взаимодействующими с концами образца , привод т образец во вращение относительно оси, проход щей через jigHTp держател , и c  eщaют держа- QFor this purpose, a holder, 25 fitted with pressure sensors, / interacting with the ends of the sample, is used to cause the sample to rotate about the axis passing through the jigHTp holder, and with a holding Q

тель перпендикул рно к этой оси о получени  минимальной разности сигналов с датчиков.The sensor is perpendicular to this axis to obtain the minimum difference of signals from the sensors.

На чертеже изображено устройстао , реализующее способ.The drawing shows the device that implements the method.

Во вращающийс  вал 1 вмонтирована опора в виде ста.кана 2 дл  установки исследуемого, тела 3, например , бойка автомата безопасности, и регулируемый элемент - гайка 4. На стакане 2 и гайке 4 со сторон, обращенных к исследуемому телу, расположены датчики давлени  5. Отсчет показаний производитс  по шкале 6. Стакан 2 с гайкой 4 вмонтированы во вращающийс  вал 1 перпендикул рно к е.гр продольной , оси и имеют возможность перемещатьс  вдоль нее.A support in the form of a steel pipe 2 is mounted in the rotating shaft 1 to install the test body 3, for example, a safety machine head, and an adjustable element — a nut 4. Pressure glass 5 is located on the cup 2 and the nut 4 on the sides facing the test body. The readings are counted on a scale of 6. A glass 2 with a nut 4 is mounted in a rotating shaft 1 perpendicular to the axis of the longitudinal axis, and have the ability to move along it.

Цри работе вал 1 привод т во вращение вместе с в.ситроенным в него стаканом 2. Исследуемое тело 3, расположенное в стакане 2 и зажатое гайкой 4, под воздействием центробежной силы давит на один из датчиков давлени  5, который-вьщае.т соответствующий сигнал. Оператор останавливает вал 1, перемещает стакан 2 в сторону несработавшего датчика 5 и вновь приводит во вращение вал .. When operating, shaft 1 is rotated together with cup 2 fitted into it. Investigated body 3, located in cup 2 and clamped by nut 4, under the influence of centrifugal force, presses on one of the pressure sensors 5, which is the corresponding signal . The operator stops the shaft 1, moves the glass 2 in the direction of the failed sensor 5 and again causes the shaft to rotate ..

Операции повтор ютс  до тех пор, пока будет срабатывать хот  бы один из датчиков 5. В тот момент, когда один из датчиков давлени  5 не будет срабатывать, т.е. когда центр т жести исследуемого тела совпадет с , осью вращени  вала 1, на шкале 6 будут показани  искомой координаты центра т жести , соответствующие рассто нию от дна стакана 2 до оси вращени  вала 1. .The operations are repeated until at least one of the sensors 5 is triggered. At the moment when one of the pressure sensors 5 does not work, i.e. when the center of gravity of the investigated body coincides with the axis of rotation of shaft 1, on a scale of 6 there will be readings of the desired coordinate of the center of gravity corresponding to the distance from the bottom of glass 2 to the axis of rotation of shaft 1..

Изобретение позвол ет с высокой точностью определить центр т жести тел вращени .The invention makes it possible to determine with high accuracy the center of gravity of the body of revolution.
