Description
Изобретение относитс к потенциометрам с сопротивлением кольцеобразной формы, по которому перемещаетс подвижный контакт, во врем перестановки отводимый с помощью электромагнита от сопротивлени .This invention relates to potentiometers with a ring-shaped resistance through which a moving contact is moved, which during removal is removed by an electromagnet from resistance.
Предлагаемый потенциометр отличаетс от известных тем, что указанный электромагнит снабжен неподвижным кольцеобразным магнитопроводом , ось которого совпадает с осью вращени подвижного контакта.The proposed potentiometer differs from the known ones in that the electromagnet is provided with a fixed ring-shaped magnetic core, whose axis coincides with the axis of rotation of the moving contact.
Такое выполнение дает возможность уменьщать габариты потенциометров с переставным контактом, управл емым электромагнитом, и устран ет необходимость применени гибких или скольз щих проводникок дл подвода тока к обмотке электромагнита.This embodiment makes it possible to reduce the dimensions of the potentiometers with a movable contact controlled by an electromagnet, and eliminates the need to use flexible or sliding conductors to supply current to the electromagnet winding.
На чертеже изображен предлагаемый потенциометр в разрезе.The drawing shows the proposed potentiometer in the section.
По кольцеобразному сопротивлению 1 потенциометра скользит подвижный контакт 2. Во врем перестановки он отводитс от сопротивлени посредством электромагнитной системы, состо щей из неподвижного кольцеобразного магнитопровода 3 с обмоткой 4 и подвижного кор 5, жестко св занного с подвижным контактом 2. Ось магнитопровода 3 расположена коаксиально оси кор и подвижного контакта.The moving contact 2 slides along the potentiometer's annular resistance 1. During the shift, it is removed from the resistance by means of an electromagnetic system consisting of a fixed ring-shaped magnetic conductor 3 with a winding 4 and a movable core 5 rigidly connected to the movable contact 2. The axis of the magnetic conductor 3 is coaxial to the axis core and moving contact.
Дл удержани подвижного контакта 2 во включенном состо нии и предотвращени трени кор 5 о магнитопровод 5 во врем вращени потенциометра корь не доходит до магнитопровода на 0,2-0,3 мм.To keep the movable contact 2 in the on state and prevent the core 5 from rubbing against the magnetic core 5 during rotation of the potentiometer, the measles do not reach the magnetic conductor by 0.2-0.3 mm.
Дл устранени люфтов при вращении подвижного контакта в качестве поводка, св зывающего его с осью 6 потенциометра, применена кольц ,ева пружина 7, один конец которой крепитс винтом к подвижной головке 8, а второй - прикреплен к втулке 9, укрепленной на оси 6.To eliminate backlash when rotating the movable contact, a ring was used as a driver connecting it with the axis 6 of the potentiometer, one spring 7, one end of which is fastened with a screw to the mobile head 8, and the second attached to the sleeve 9 fixed on axis 6.
Якорь 5 соедин етс с подвижной головкой 8 при помощи двух боковых алюминиевых стоек 10.The anchor 5 is connected to the movable head 8 by means of two side aluminum struts 10.
Предмет изобретени Subject invention
Потёйциометр с сопротивлением кольцеобразной формы, с наложеТ ным на сопротивление подвижным контактом и с расположенным в центре электромагнитом, служащим дл отвода подвижного контакта от сопротивлени в моменты его перестановки, отличающийс тем, ч го с целью уменьшени его габаритов и повышени надежности токоподвода к обмотке электромагнита, последний снабжен неподвижным кольцеобразным магнитопроводом, коаксиально которому расположена ось вращени подвижного контакта потенциометра.A ring gauge with a ring-shaped resistance, a movable contact superimposed on the resistance and an electromagnet located in the center serves to remove the movable contact from the resistance at the moments of its exchange, in order to reduce its dimensions and increase the reliability of the current lead to the electromagnet winding, the latter is equipped with a fixed ring-shaped magnetic core, coaxial to which the axis of rotation of the movable contact of the potentiometer is located.
