SU1528979A1 - Rotary reciprocatory motion converter - Google Patents

Abstract

The invention relates to mechanical engineering, in particular to transducers of mechanical movement. The purpose of the invention is to increase efficiency, reliability and compactness. A feature of the design and its operation is that the rotation of the output shaft 3 of the engine 2 is transmitted through a cylinder 8, rigidly mounted on the shaft 3, and the leads 9, evenly spaced rotatably around its axis around the circumference of the cylinder 8, on closed grooves 6 made on the inner cylindrical surface 5 of the pusher 4. The pusher 4 is housed in the housing 1 with rotation restriction due to the clamp 10 and has the possibility of only a linear movement within the length of the groove 11 in which the clamp 10 is located. acting on the side walls of the grooves 6, with its rotation, the pusher 4 is reported to reciprocate. Such a converter design allows for the creation of a compact, hermetic, reliable manual mechanical drive. 1 il.

The invention relates to mechanical engineering, in particular to transducers of mechanical movement.

The purpose of the invention is to increase efficiency, reliability and compactness by making the transmission link in the form of several pairs symmetrical with respect to each other: a lead is a groove.

The drawing shows a longitudinal section of the Converter.

The rotary to reciprocating motion converter consists of the housing 1, which is rigidly connected to the engine 2 housing (electric, pneumatic or any other) with the rotating output shaft 3, the pusher 4 in the form of a glass, on the inner cylindrical surface 5 of which there are closed grooves 6, each of which is located in a plane extending at an angle of less than 90 ° to the axis of the pusher 4, and fastening 7 for the drive device (not shown) is mounted on the outer end surface, the cylinder 8, pusher concentric with barrier rods 9 mounted uniformly on the circumference of the cylinder 8 to rotate about its axis. The leads 9 are placed in their respective grooves 6, and the shape of the grooves 6 in the normal section repeats the shape of the leads 9 in cross section. To prevent the pusher 4 from rotating, a latch 10 is installed on it, which is placed in the groove 11 of the housing 1. The latch 10 can be provided with a rotating element for converting sliding friction into rolling friction. Instead of the elements - the latch 10 and the groove 1 1 - other elements that do not allow rotation can be applied, for example, the splines, the slats are square or polygonal, the outer surface of the pusher 4 in cross section, etc. The cylinder 8 is fixed on the output shaft 3 of the engine 2.

The Converter operates as follows.

When rotating the cylinder 8, fixed on the output shaft 3 of the engine 2, the drivers 9 interact with the closed grooves 6 of the pusher 4, moving it in the axial direction in one direction or the other. The pusher 4 through the mount 7 acts on the drive unit. The rotation of the pusher 4 is achieved by installing the latch 10, which interacts with the groove 11 made in the housing 1. Thus, the rotational movement of the cylinder 8 is converted into the reciprocating movement of the pusher 4.
