TRANSMISSION FOR TANSMISSION SYSTEMS IN DEVICES FOR METERING OF GRANULATED MATERIALS Russian patent published in 2007 - IPC F16H29/08 

Abstract RU 2292504 C2

FIELD: mechanical engineering.

SUBSTANCE: invention relates to transmissions with interrupted-action drive members whose gear ratio is changed by adjusting path of motion, arrangement of hinge joint or working length of rocking connecting member. Proposed transmission contains input crankshaft 5 and output shaft 6 of drive. Pair of coaxial free-wheeling wheels 8 is secured on drive output shaft 6. Free-wheeling wheels 8 are provided with joints 10 with movable support point means which are active ones. Opposite end of each joint is set into reciprocating oscillation relative to support point means by eccentric device. Said eccentric device is arranged on drive input crankshaft for converting reciprocating oscillation of drive input crankshaft 5 into interrupted rotation of each-wheeling wheel 8. Interrupted rotation of each free-wheeling wheel 8 sets drive output shaft 6 into rotation. Drive input crankshaft 5 has one pair of cranks with eccentric pins 11. Each joint 10 has corresponding member similar to connecting rod. Said connecting rods are connected by one end with corresponding free-wheeling wheels 8, and by end are hinge-connected with eccentric pins 11 of drive input crankshaft 5 for rotation and translational motion relative to eccentric pin 11. Each pin of support point permits adjustment within the limits of connecting rod member. Each pin of support point is connected by one end on stationary transmission for sliding in seat made in wall of housing 3. Other end of support point pin is connected with connecting rod so that pin of support point forms center of rotation, each pin of support point being connected with adjusting devices for adjusting gear ratio between drive input crankshaft and drive output shaft of transmission. Transmission is used to control transmission to corresponding metering members of metering device of granulated materials and/or powder materials and it can be used in agricultural sewing machines.

EFFECT: provision of uniform operation of free-wheeling wheels connected with drive output shaft to provide operation of transmission members independently from any elastic displacement means.
