(54) КУЛАЧКОВЫЙ МЕХАНИЗМ(54) CAM MECHANISM

II

TlsoGpeieHHe относитс к машиностроению, а именно к кулачковым механизмам.TlsoGpeieHHe relates to mechanical engineering, namely, cam mechanisms.

Известен кулачковый механизм, содержащий корпус, установленный в нем ведущий вал с кулачком, взаимодействующий с кулачком одним концом рычаг, другой конец которого шарнирно св зан с промежуточным звеном, взаимодействующим с ведомым звеном 1.A cam mechanism is known, comprising a housing, a drive shaft with a cam mounted therein, a lever interacting with the cam at one end, the other end of which is pivotally connected to an intermediate link cooperating with the driven link 1.

Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс кулачковый механизм, содержаадай корпус, установленные в нем ведущий вал с кулачком, взаимодействующий с кулачком одним концом рычаг, другой конец которого шарнирно св зан с корпусом, промежуточное и ведомое звень ,установленные с возможностью вращени относительно корпуса,и два ролика.The closest in technical essence and the achieved result to the invention is a cam mechanism, comprising a housing, a drive shaft with a cam mounted therein, a lever interacting with the cam at one end, the other end of which is hinged to the housing; rotation relative to the housing, and two rollers.

Недостатком известных механизмов вл етс невозможность регулировани параметров движени ведомого звена.A disadvantage of the known mechanisms is the impossibility of adjusting the motion parameters of the slave link.

Целью изобретени вл етс обеспечение возможности регулировани параметров движени ведомого звена.The aim of the invention is to provide the possibility of adjusting the motion parameters of the slave link.

Указанна цель достигаетс тем, что в кор пусе параллельно ос м вращени промежуточного и ведомого звеньев выполнены две направл ющие, механизм снабжен двум т гами , установленными в направл ющих с возможностью перемещени вдоль них, жестко св занной с ведомым звеном платформой,имеющей профилированную поверхность и двум дополнительными роликами,св занными с одной из т г и взаимодействующими с рычагом и промежуточным This goal is achieved by the fact that in the case parallel to the axis of rotation of the intermediate and slave links there are two guides, the mechanism is equipped with two ways installed in the guides with the ability to move along them, rigidly connected with the driven link platform having a shaped surface and two additional rollers connected to one of the tg and interacting with the lever and the intermediate

Claims

The cam mechanism comprises a housing 1, a drive shaft 2 installed therein with a cam 3, a lever 4 cooperating with the cam 3 at one end, the other end of which is pivotally connected to the housing 1, an intermediate 5 and a driven 6 link that are rotatably mounted relative to the housing 1 , two rollers 7 and 8. In case 1, two guides 9 and 10 are made parallel to the axis of rotation of the intermediate 5 and slave 6i links. The mechanism also contains two links 11 and} 2, mounted in the guides 9 and 10 with the possibility of moving along them tightly bound to the ve The wash link 6 of the platform 13, having a profiled surface 14, two additional rollers IS and 16, associated with the first th 11 and interacting with the lever 4 and intermediate link S and the profiled surface 14, and the axes of rotation of the drive shaft 2 and the lever 4 are parallel between themselves and perpendicular to the plane passing through the axes of rotation of the intermediate 5 and the slave links 6. The mechanism is forcefully closed by an elastic element 17. The cam mechanism operates as follows. When the movement of the drive shaft 2 is communicated, the cam 3 communicates to the lever 4 an oscillatory motion, which through Additional rollers 15 and 16, intermediate link 5, main rollers 7 and 8, platform 13 with profiled surface 14 is transmitted to slave link 6. The amplitude of the variable component of oscillation is regulated by moving the rod 11 in the guides 9, and the average value of the oscillations is adjusted by moving the rod 12 in the directions 10. Thus, the device allows the adjustment of both the average value and the amplitude rows of the variable component of oscillations of the driven member 6, which allows to extend the range of the spectral characteristics of the displacement actuators. The cam mechanism can be used in hydraulic follow-up systems when analyzing mechanical disturbances acting on devices. Claim mechanism, comprising a housing, a drive shaft mounted therein with a cam, a lever interacting with a cam at one end, the other end of which is pivotally connected to the housing, an intermediate and a driven member mounted rotatably relative to the housing, and two rollers, characterized in that, in order to enable the control of the motion parameters of the slave link, in the housing two guides are parallel to the rotational axis of the intermediate and slave links, the mechanism is equipped with two connecting rods mounted in guides movably along them rigidly associated with the platform driven member having a profiled surface, and two further rollers coupled with one of the rods; and interacting with the lever and the intermediate link, the two main rollers are connected with the other thrust and interact with the intermediate link and the profiled surface, and the axes of rotation of the drive shaft and the lever are parallel to each other and perpendicular to the plane passing through the axes of rotation of the intermediate and driven links.
