MECHANISM FOR CONVERTING ROTATION INTO RECIPROCATION AND VICE VERSA Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: additional gear sector 14 is mounted inside housing 1. Both of the sectors have 60-100° arcs. The intermediate link is constructed as crank 4 with two cylindric shields 8 and 9 at the respective ends and web 10 interposed between them. Shaft 3 has eccentrically positioned opening 7 radius of the eccentricity of which is equal to the radius of crank 4 and radius of the separating circumference of the gear sector of the crank respectively. The gear sector of crank 4 is made on the web and serves for alternative interaction with the gear sectors of the housing. When shaft 3 is in rotation crank 4 rotates in opening 7 of the shaft resulting in motion converting. EFFECT: enhanced efficiency. 4 dwg
