ECCENTRIC CONNECTING ROD Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention relates to transmissions converting motion by means of cranks and eccentrics. Connecting rod has disk-eccentric with round hole by means of which it is fitted on cylindrical shaft and is rigidly secured on shaft. Disk-eccentric is coupled with link of connecting rod by means of rolling devices. Link of connecting rod is coupled with operating link installed for reciprocation. Center of hole of disk-eccentric is displaced from center of disk through crank radius value. Radius of disk-eccentric is greater than sum radii of crank and shaft. Rollers are arranged on surface of outer diameter of disk-eccentric and are enclosed by holders, ring housing and load-bearing walls forming connecting rod link. These walls have narrowed ends with holes. Common axle of hinge joint of connecting rod link and operating link is fitted in these holes. Disk-eccentric and cylindrical shaft are made for rotation around one common axis passing through center of eccentricity hole of disk-eccentric and along axis of cylindrical shaft. EFFECT: reduced cost of eccentric connecting rod, improved operating characteristics. 9 dwg
