FIELD: mechanical engineering+ADs- leverage mechanisms with flexible couplings+ADs- belt transmissions of conveyers. SUBSTANCE: proposed leverage mechanism includes crank 1, rocker arm 2 and flexible runs 7 and 8. Crank 1 and rocker arm 2 are interconnected by means of two flexible closed runs 7 and 8 through rollers 5 in such way that turn of crank 1 in clockwise direction causes transmission of motion to rocker arm 2 through flexible closed run 8 and turn of crank 1 in counter-clockwise direction causes transmission of motion to rocker arm 2 through flexible closed run 7.Rollers are made in form of elliptical bodies at ratio of axes of from 1.0 to 2.0. EFFECT: enhanced strength and reliability. 3 dwg |
