POWER TRANSMISSION ARRANGEMENT, METHOD FOR POWER TRANSMISSION IN A GEAR SYSTEM AND USE OF POWER TRANSMISSION ARRANGEMENT

摘要

The power transmission arrangement according to the invention comprises at least a gear arrangement that has a first axle (2) rotating around its central axis, and a second axle (3, 3b) rotating around its central axis, and two or more pinion gear assemblies (13), having at least two pinion gears (15-17) with mutually different reference diameters and fitted coaxially on the same rotating support shaft (14). In addition the gear arrangement comprises internally geared ring gears (18-20) meshing with the pinion gears (15-17), and one ring gear (18, 19) at a time is arranged to be stationary locked non-rotary in relation to the housing (1 ). The pinion gears (15-17) rotate at the same speed and to the same direction with their support shafts (14) and mutually with each other, and that at least one pinion gear (15a, 17) of each pinion gear assembly (13) is arranged to mesh with the rotary internally geared ring gear (18a, 20).
