TOOTHED CHAIN TRANSMISSION

摘要

FIELD: machine building.SUBSTANCE: toothed chain transmission includes drive (1) and driven (2) sprockets and bushing-roller chain (5) enveloping them for transmission of the first power flow. Evolvent gear wheel (3) and sprocket (1) engaged with it form the second power flow. The second evolvent wheel (4) installed on one and the same axis together with the first wheel is engaged with the second sprocket (2). Drive and driven sprockets fall behind each other along their axes by the value equal to the distance between rows of the chain. Bushing-roller chain is two-row.EFFECT: invention allows increasing total transmitted power and kinematic accuracy of toothed chain transmission.2 dwg
