Transmission has gear trains connected by crossing-axes gears - and has infinitely variable overall transmission ratio

摘要

The transmission comprises a first gear train (A'), a transmission (B) with crossing axes and a driven gear train (C'). The arrangement is such that in the transmission (B), the torque from the first train (A') is increased, and torque conversion takes place in the second train (C') so that it can supply a greater torque output. The transmission (B) is permanently connected with (A') and (C') and the overall transmission ratio is infinitely variable. The first train may consist of two pairs of gears (52-53, 55-56) in series, the gears (53, 55) being carried on an intermediate shaft (54). This shaft is connected with the central shaft (27) by a crank (58) whilst the last gear (56) of this train is coupled to a wormwheel (29) of transmission (B).
