CONVERSION METHOD OF BACK-AND-FORTH MOVEMENT OF STOCK TO ROTATIONAL MOVEMENT OF SHAFT, CONVERTER FOR ITS IMPLEMENTATION (VERSIONS), AND ENGINE USING SUCH CONVERTER Russian patent published in 2013 - IPC F16H23/00 F02B75/26 F02B75/32 

FIELD: machine building.

SUBSTANCE: conversion method of back-and-forth movement of stock to rotational movement of a shaft consists in the fact that stock (2) acts during the working stroke on two surfaces formed in one cylinder (1), as a result of which cylinder (1) receives rotation, and return of stock (2) to initial position is provided due to kinetic energy accumulated in a kinetic energy accumulator. Two surfaces are made in one cylinder (1) in the form of equal closed oval surfaces (A) and (B), which are parallel to each other and located at equal angle to axis of stock (2) and forming a through slot dividing the cylinder into two equal parts. Cylinder (1) is placed into cylindrical housing (6) of larger diameter, which is coaxial to it, so that external surface of internal cylinder (1) adjoins the internal surface of external cylindrical housing (6). Cylindrical housing (6) is installed in bearings (8) with possibility of rotation and rigidly attached to internal cylinder (1) by means of pins (7). As a kinetic energy accumulator, flywheel (9) rigidly fixed on cylindrical housing (6) is used. Stock (2) acts on the surfaces through pin (3) rigidly fixed on it, which slides on oval surface (A) of cylinder (1) slot during the working stroke and turns cylinder (1) relative to stock (2) so that when pin (3) reaches lower point (C) in oval surface (A), it makes cylinder (1) turn relative to stock (3) through 180°; after that, pin (3) moves to oval surface (B) of cylinder (1) slot. When stock (2) moves in reverse direction, it slides on surface (B) till it reaches upper point (D) on oval surface (B), thus making cylinder (1) turn relative to the stock through 360°; after that, stock (2) moves to oval surface (A) and the cycle is repeated. Versions of design of converters of the stock back-and-forth movement to the shaft rotational movement and the internal combustion engine using the above converters are described.

EFFECT: simpler manufacturing technology.
