MECHANISM FOR CONVERTING UNIFORM ROTARY MOTION INTO NON-UNIFORM ROTARY MOTION Russian patent published in 1994 - IPC

FIELD: conversion of uniform rotary motion into non-uniform rotary motion. SUBSTANCE: device has two movable slotted cams and two fixed cams; working surface of one of cams is outer surface and working surface of other cam is inner surface. Fitted between movable cams is disk with guides. Pins with rollers at their ends are secured in pairs in arc slide blocks mounted in fixed cams. During uniform motion of disk with guides, pins with rollers roll over working surfaces of fixed cams carrying movable cams together with them and transmitting non-uniform motion to them which is then transmitted to the output shaft. EFFECT: enhanced reliability due to uniform distribution of loads. 4 dwg
