Abstract

Изобретение относитс к машиностроению и может быть использовано в различных устройствах дл преобразовани вращательного движени ведуще го звена в возвратно-поступательное движение ведомого н наоборот.Цель изобретени - повышение надежности путем уменьшени ударных нагрузок на элементы механизма. Положительный эффект достигаетс тем, что рейки 2 и 3 выполнены в виде обращенных навстречу друг другу меньшими основани ми клиньев с поперечным сечением в форме равнобедренной трапеции, а на наружной поверхности колеса 5 выполнены предназначенные дл взаимодействи с рейками 2 и 3 дугообразные канавки, длина которых равна половине началь - ной окружности колеса 5, а форма профил аналогична форме сечени рег- ек 2 и 3. 3 ил. « СЛThe invention relates to mechanical engineering and can be used in various devices for converting the rotational motion of the drive link into the reciprocating movement of the driven member but vice versa. The purpose of the invention is to increase reliability by reducing the impact loads on the elements of the mechanism. The positive effect is achieved by the fact that rails 2 and 3 are made in the form of wedges facing towards each other with smaller bases with an cross section in the form of an isosceles trapezium, and on the outer surface of the wheel 5 arcuate grooves designed to interact with the rails 2 and 3 are equal to half of the initial circumference of the wheel 5, and the shape of the profile is similar to the shape of the section of the regenok 2 and 3. 3 sludge.

Claims

Claim

A mechanism for converting movement, comprising two parallel mounted rails and a wheel designed to alternately interact with them, characterized in that, in order to increase reliability by reducing shock loads, the rails are made in the form of wedges facing each other with smaller bases with a cross section in the form an isosceles trapezoid, and on the outer surface of the wheel there are made arcuate grooves designed to interact with the rails, the length of which is equal to half the initial circumference wheels ^ and the shape of the profile is similar to the shape of the cross-section of the rails.
