Abstract

The invention allows for intermittent reciprocating movement of the rod. The drive and driven shafts 1, 2 with pulleys 3, 4 of the same diameter are interconnected by means of a cover, its flexible link 5. The rod 6 is installed in the housing 7 with the possibility of reciprocating movement. The slider 8 is connected to the flexible link and is mixed in the direction of the slider, which is rigidly connected to the rod and is made in the form of two concentrically arranged rings 9, 10, whose axis is parallel and is in the same plane with the axes of the shafts 1, 2 The yush is guided, it is a roller bearing, in which the slider 8 is a bearing roller and the rings 9 and 10 are played by the inner and outer shells of the roller bearing, respectively. 2 Il.

The invention relates to mechanical engineering and can be used in machines requiring intermittent reciprocating motion, for example in piston machines, automatic lines, muscle-driven machines, engines.

The purpose of the invention is to provide intermittent reciprocating motion of the rod.

FIG. 1 is a schematic diagram of the proposed mechanism; in fig. 2 - structural scheme of the proposed mechanism.

The mechanism for converting the rotational movement into reciprocating motion includes the driving and driven shafts 1, 2 with izhivami 3, 4 of the same diameter, covering their flexible link 5, the rod 6, installed in the housing 7, the slide 8, moving in the guide slide and the guide slide is made in the form of two concentrically arranged rings S, 10, the axis of which is parallel and located in the same plane with the axes of the shafts 1, 2.

 The mechanism works as follows. i When the drive shaft 1 rotates together (jo pulley 3 flexible link 5 leads to

The movement of the pulley 4. The slider 8, connected by c1 flexible link 5, interacts with the ring-shaped guide, rigidly

fortified with rod 6.

force, braking the translational movement of the guide and stem 6 of the rings 9, 10 over the axis of the shaft 1, i.e. in the section of the trajectory of the slide 8 from point b to point c

rod 6 is practically at rest. The force applied along the axis of the rod 6 through the outer ring 10 rigidly fastened to it acts on the slider 8, which is connected with the flexible link 5 which carries the slider 8 with itself.

Further, the mechanism works in a similar way. According to the structural scheme of the mechanism (Fig. 2), the guide is a roller bearing, in which the slider 8 is a bearing roller, and the inner and outer shells of the roller bearing play the role of the inner ring 9 and the outer ring 10. The rod 6 has a rectangular cross section and slides freely in the guides of the housing 7.
