Description
Известно применение в приспособлении дл изменени пропорциональности шкалы в электрических измерительных приборах спиральных пружин, приход щих в сцепление со стрелкой, закрепленных на оси одним концом, вследствие чего получаетс провисание пружины и ненадежность как в зацеплении, так и в работе.It is known to use a device for changing the proportionality of a scale in electric measuring instruments of spiral springs coming into engagement with an arrow fixed on an axis at one end, as a result of which a spring sag and unreliability are obtained both in engagement and in operation.
В предлагаемом же приспособлении этот недостаток устран етс путем противодействующей цилиндрической пружины, укрепленной под шкалой.In the proposed device, this disadvantage is eliminated by an opposing cylindrical spring, reinforced under the scale.
В этом приспособлении, схематически изображенном на чертеже, под шкалой в той части, в которой желательно получить измененные отклонени , закрепл етс цилиндрическа пружина а перпендикул рно к направлению движени стрелки. В шкале же делаетс вырез дл штифта Ь, припа нного к середине лружины а: При отклонении стрелка с задевает за штифт и тормозитс пружиной. Таким образомIn this device, shown schematically in the drawing, a cylindrical spring is fixed under the scale in the part in which it is desirable to obtain altered deviations, and perpendicular to the direction of movement of the arrow. In the scale, a cutout is made for pin b, attached to the middle of the spring a: When deflected, the arrow with touches the pin and brakes with a spring. In this way
осуществл етс изменение отклонений подвижной системы.the variation of the deviations of the mobile system is carried out.
Это приспособление, по мнению авторов , пригодйо как дл приборов с перегрузочной шкалой, так и дл изменени отклонений в любой части шкалы.This device, according to the authors, is useful both for instruments with a reloading scale, and for changing deviations in any part of the scale.
Предмет патента.The subject of the patent.
Приспособление дл изменени пропорциональности шкалы в электрических измерительных приборах посредством создани дополнительного, противодействующего движению стрелки момента в случае предельного отклонени последней, OTAH4aroigeecfl тем, что пружина, задерживающа движение стрелки, выполнена в виде закрепленной с обоих концов спирали , расположенной, с обратной стороны шкалы, перпендикул рно к движению стрелки, и тормоз щей движение последней посредством выступа Ь, помещенного в средней части пружины.A device for changing the proportionality of the scale in electrical measuring instruments by creating an additional moment opposing the movement of the arrow in the event of maximum deviation of the latter, OTAH4aroigeecfl by the fact that the spring that delays the movement of the arrow is made in the form of a perpendicular fixed from both ends of the helix It is directed towards the movement of the arrow, and the movement of the latter is slowed down by means of a protrusion b placed in the middle part of the spring.
