Abstract
A power transmission system for transmitting power between sprockets mounted on rotating members. The system includes a chain comprising a plurality of transverse elements maintained in a stack by a carrier received in slots in each transverse element. Power is transmitted along the chain by contact between the principal faces of the transverse elements. The transverse elements include a plurality of load bearing elements which are configured to engage the teeth of the sprockets and to provide power transmission therewith. The chain extends along a run from a driving sprocket to a driven sprocket and moves along the run from the driving sprocket to the driven sprocket. An antibuckling guide is positioned along the run to prevent deflection of the chain perpendicular to the run.
Claims5
A power transmission system, comprising:
- a driving sprocket and a driven sprocket, said sprockets having teeth formed about their outer periphery;
- a compression chain at least partially wrapping around said sprockets along an inner surface of the chain, and extending along a run between the sprockets;
- said compression chain including a carrier extending along said chain and a plurality of transverse elements arranged along said carrier, each of said transverse elements having at least one recess formed therein, said carrier being received in recesses in said transverse elements;
- a first number of said plurality of transverse elements having a first profile and a second number of said plurality of transverse elements having a second profile;
- said transverse elements having said first profile configured and positioned to engage said teeth of said sprockets and the second number of traverse elements having said second profile being configured and positioned above the outer periphery of the said teeth;
- said compression chain extending along a run from the driving sprocket to the driven sprocket;
- said driven sprocket driven to rotate to cause the chain to move along the run from the driving sprocket toward the driven sprocket;
- an antibuckling guide positioned along the run to prevent the chain from significant deflection perpendicular to the run.
