Изобретение относитс к приборам дл воспроизведени математических кривых и может быть использовано, например, в учебном процессе ВУЗов.The invention relates to instruments for reproducing mathematical curves and can be used, for example, in the educational process of universities.

Цель изобретени - расширение диапазона воспроизводимых кривых путем обес- 5 печени воспроизведени трисектрисы Лон- шама.The purpose of the invention is to expand the range of reproducible curves by allowing the liver to reproduce the Lonsham trisection.

На чертеже представлена кинематическа схема механизма. The drawing shows the kinematic scheme of the mechanism.

Механизм содержит два звена 1, 2, соос- ю но закрепленные в шарнире О на направл ющей 3 и св занные между собой шарнирным ромбом ОСАВ, образованным звень ми 4, 5, в вершине А ромба закреплен ползун 6, установленный на направDOC и, кроме того, угол GOK в 2 раза больше угла EOG. Отсюда из треуголь- ника РОК вытекает пол рное уравнение кривой, воспроизводимой точкой F.The mechanism contains two links 1, 2, coaxially fixed in the hinge O on the guide 3 and interconnected by a hinged rhomb of the OSAV formed by links 4, 5, at the top A of the rhombus fixed a slider 6 mounted on the DOC direction and, besides In addition, the GOK angle is 2 times the EOG angle. From this, the ROK triangle leads to the polar equation of the curve reproduced by point F.
