摘要

The gear i.e. double crank gear, has two coaxially arranged crank arm elements (12, 14) connected by an eccentrically arranged hollow stroke tap (16). A shaft is driven by the crank arm elements, where driving torque of a reciprocating piston engine is introducable in a power train by the shaft. The shaft is arranged eccentrically and parallel to a rotational axis (20) of the arm elements. The arm elements are provided with external teeth (26, 28). A bearing (22) e.g. connecting rod bearing and roller bearing, is carried by the tap.
