Description

ff

Изобретение относитс к машиностроению , а именно к преобразовател м вращательного движени в возвратно- качательное, и может быть использовано в различных устройствах, где требуетс такое преобразование.The invention relates to mechanical engineering, namely, to converters of rotational movement into reciprocating, and can be used in various devices where such a conversion is required.

Цель изобретени - уменьшение габаритов механизма за счет более удачной компановки и нового сочлене ни звеньев механизма.The purpose of the invention is to reduce the dimensions of the mechanism due to a more successful arrangement and a new joint of the links of the mechanism.

На чертеже изображена кинематическа схема предлагаемого механизма .The drawing shows the kinematic scheme of the proposed mechanism.

Механизм содержит основание 1 с пр молинейной направл ющей 2, кри- : вощип 3, коромысло 4 и шарнирно св зывающие их между собой шатуны 5 и 6. Другие концы шатунов 5 и 6The mechanism contains a base 1 with a straight-line guide 2, a curve-: voschip 3, a yoke 4, and connecting rods 5 and 6 that pivotally connect them to each other. Other ends of the connecting rods 5 and 6

с ползуном 7, размещенным в направл ющей 2. with slider 7 placed in guide 2.

Оси вращени кривошипа 3 и коромысла 4 размещены на продольной оси направл ющей 2, а рассто ние между ними равно сумме длин кривошипа 3 и шатунов 5 и 6 без длины коромысла 4.The axis of rotation of the crank 3 and the rocker 4 is placed on the longitudinal axis of the guide 2, and the distance between them is equal to the sum of the lengths of the crank 3 and the connecting rods 5 and 6 without the length of the rocker 4.

, Механизм работает следующим об- разом.The mechanism works as follows.

Вращение кривошипа 3 через шатун 5 преобразуетс в возвратно-поступательное движение ползуна 7, которое через шатун 6, в свою очередь, преобразуетс в возвратно-качатель- ное движение коромысла 4.The rotation of the crank 3 through the connecting rod 5 is converted into a reciprocating movement of the slider 7, which through the connecting rod 6, in turn, is converted into a reciprocating swinging movement of the rocker arm 4.

Claims

CRANK-SLIDING MECHANISM, containing a base with a straight guide, a crank and a rocker arm, placed on the base so that their axis of rotation are located on the longitudinal axis of the guide, two connecting rods pivotally connected at one end to another, and the other: the first - with a crank, and the second with the rocker, and the slider pivotally connected to the first connecting rod, which is located in the guide, characterized in that, in order to reduce the dimensions, the second connecting rod is also pivotally connected to the slide, the axis of the hinges connecting the connecting rods to one and the other m, combined, and the distance between the axes of rotation of the crank and rocker arm is equal to the sum of the lengths of the crank and connecting rods minus the length of the rocker arm.
