Изобретение относитс к машиностроению, а именно к устройствам дл преобразовани вращательного движени в возвратнопоступательное .The invention relates to mechanical engineering, in particular to devices for converting rotary motion into reciprocating.

Известно устройство дл преобразовани вращательного движени в возвратно-поступательное , содержащее кривоигап с роликом, взаимодействующий с криволинейной кулисой, щарнирно соединенный с кулисой шатун, взаимодействующий с исполнительным звеном 1.A device for converting rotary motion into reciprocating, containing a crank with a roller, interacting with a curvilinear slide, pivotally connected to the connecting rod with a link, interacting with an executive link 1, is known.

Недостатком известного устройства вл етс его мала динамическа устойчивость, привод ща к снижению точности перемещений исполнительного звена.A disadvantage of the known device is its low dynamic stability, leading to a decrease in the accuracy of movement of the actuator.

Наиболее близким к предлагаемому вл етс устройство дл преобразовани вращательного движени в возвратно-поступательное, содержащее кривоигапно-ползунный механизм, кулачковый механизм и исполнительное звено 2.Closest to the present invention is a device for converting rotary motion into reciprocating, comprising a slider-cam mechanism, a cam mechanism, and an actuator 2.

Недостатком известного устройства вл етс ограниченный диапазон спектральных характеристик линейных перемещений исполнительного звена вследствие зависимости перемешеНИИ только от геометрических и частотных параметров кривошипно-ползунного мехаьшзма.A disadvantage of the known device is the limited range of the spectral characteristics of the linear displacements of the executive link due to the dependence of the mixing head only on the geometric and frequency parameters of the crank-slider mechanism.

Цель изобретени - распшрение диапазона спектральных характеристик линейных перемещений исполнительного звена.The purpose of the invention is to spread the range of the spectral characteristics of the linear displacements of the executive link.

Указанна цель достигаетс тем, что устройство снабжено дополнительным игатуном, шарнирно св занным одним концом с исполнительным звеном, и Г-образлым коромыслом, шарнирно св занным концами с роликом и This goal is achieved in that the device is equipped with an additional igatun, which is pivotally connected at one end to the executive link, and a L-shaped rocker, pivotally connected at the ends with a roller and

10 другим концом дополнительного шатуна, а вершиной - с ползуном.10 the other end of the additional connecting rod, and the top - with a slider.

Claims

15 contains a crank-slider mechanism consisting of a crank ax 1, a connecting rod 2, a slider 3, a cam mechanism consisting of a cam 4 and a roller 5 interacting with it, an actuating element 6, an additional one; a connecting rod 7 connected by a single hinge an end with an executive link 6, an L-shaped rocker 8, pivotally connected by ends 9 and 10 with a roller 5 and the other end 3 of an additional connecting rod 7, and with an apex 11 with a slider 3. The device works as follows. Rotational movement of crank 1 is converted through rod 2, slider 3, L-shaped rocker 8 and additional rod 7 into reciprocating movement of the executive link 6. The parameters of the spectral characteristics of the linear mixing of the executive link 6 depend on the cam profile 4, as well as on the frequency Crank 1 and the geometrical characteristics of all parts of the device for converting movement. The proposed device for converting rotary motion into reciprocating has a wide range of spectral characteristics of linear displacements of the actuator, dynamic stability and reliability in operation. A device for converting rotary motion into reciprocating, comprising a slider crank mechanism, a cam mechanism and an actuator, characterized in that, in order to expand the range of the spectral characteristics of the linear displacements of the actuator, it is provided with an additional connecting rod tied with one ball. an end with an executive link, and an L-shaped rocker, pivotally connected by ends with a roller and the other end of an additional connecting rod, and the apex - with a slider.
