Description

(5) A DEVICE FOR THE TRANSFORMATION OF A RETURN MOTION RETURN MOTION,

. . 1 The invention relates to mechanical engineering, namely, devices for converting reciprocating motion into rotary motion. A device for converting a reciprocating motion into a rotational one is known, comprising a housing, rocker mechanisms housed therein, connected by driving and driven cranks with rollers interacting with slotted cams, bellows fixed on a core. The emptying and enclosing cams of the GPG. The disadvantage of this device is its low reliability due to the uneven movement of the links, niy and large contact loads in the connections of the cams and cranks at the misalignment of the position of the connecting scenes. Closest to the invention is a device for converting a reciprocating movement into a rotary, comprising an actuator, a housing with guides, mounted therein with a possibility of a reciprocating translational motion relative to them, and a pulley interacting with a drive slider with a roller side surface mounted rotatably relative to the housing and interacting with the roller and rigid cam-connected actuator C 23. A disadvantage of the known devices It is not high accuracy displacement actuator and the inability to transmit the motion into the vacuum. . The aim of the invention is to transfer with high accuracy of movement into a vacuum. This goal is achieved by the fact that in a device for converting a reciprocating motion into a continuous rotary, comprising an actuator, a housing with guides, mounted therein with the possibility of reciprocating motion relative to them, and a slide interacting with the actuator, with a roller on its lateral surface, a groove cam with a groove on the dro side of the side surface, mounted rotatably with respect to the housing and interacting with the roller, and the actuator rigidly connected with the cam. the cam is designed as a cylinder mounted concentrically and having a zigzag-f groove; the drive is designed as an eccentric device; the device is equipped with additional rollers installed evenly around the circumference on the lateral surface of the slide and interacting with the groove wall with a sylphon rigidly connected at one end to the body and the other with a slider, elastic elements installed in the areas where the zigzag groove emerges onto the front face of the cam, and the slider is spring-loaded in the direction of the eccentric. FIG. 1 shows a device, a longitudinal section; in fig. 2, section A-A in FIG. one; in fig. The scheme of interaction of the slider of the lacque in axonometry. The device for converting the reciprocating movement into a rotary movement comprises an actuator 1, a housing 2 with guides 3, mounted therein with a possibility of reciprocating movement relative to them, and a slider 4 interacting with the actuator slider 4 with a roller 5 on its side surface on its side surface mounted rotatably with respect to the housing and interacting with roller 5, actuator 7 rigidly connected to cam 6. The rim of the cam 6 is made in the form of a cylinder, tanovlenii concentrically slider 4 and a zigzag groove 8. The actuator is designed as a cam. On the side surface of the slider evenly around the circumference, additional rollers 9 and 10 are installed, interacting with the groove wall. 8. The device also contains a bellows 11, rigidly connected at one end with the body 2, and the other with a slider 4, elastic elements 12 (one is shown) installed in the exit areas of the zigzag groove 8 on the face surface of the cam 6. The slider is spring-loaded in the direction to the actuator 1 spring 13. The device works as follows. When the actuator 1 rotates, the slider k receives a reciprocating motion. The slider rollers 5, 9, and 10 interact with the zigzag groove 8 of the cam 6. The cam 6 rotates and informs its executive link 7 rigidly connected with it. Elastic elements 12 increase the accuracy of the interaction of the rollers 5, 9 and 10 of the slide 4 with the zigzag groove 8. The proposed device has a high degree of tightness, reliability and durability, which ultimately leads to an increase in the accuracy of the motor being transferred to a vacuum. Formula of the invention A device for converting reciprocating motion neither in rotational, continuous, containing a drive, a housing with guides, mounted therein with a possibility of reciprocating motion relative to them, and a slide interacting with a drive with a roller on its side surface, a groove cam with a groove on its side surface mounted with rotation relative to the housing and interacting with the roller, and a rigidly coupled cam actuator, differing from the fact that, in order to transfer with high precision movement into vacuum, the groove cam The cylinder is mounted concentrically with a slider and having a zigzag groove, the drive is designed as an eccentric, the device is equipped with additional rollers mounted evenly around the circumference on the side surface of the slider and interacting with the wall of the groove, a bellows rigidly connected at one end to the body, and - with a slider, elastic elements installed on the part 59761586
