Abstract
In a double-oblique-toothed stage spur wheel drive, the first stage includes a first pinion which drives a first toothed wheel by way of an intermediate wheel. The first stage drives the second stage which includes a second pinion coupled with the first toothed wheel and a second toothed wheel meshing with said second pinion. The first pinion and the first toothed wheel each include a respective coaxial pair of gear wheel halves having oppositely-directed oblique teeth, and the intermediate wheel includes two pairs of intermediate gearwheel halves, with all of the gear wheel halves being coaxially disposed. One of said intermediate gear wheel half pairs engages with the first pinion and the other engages with the first toothed wheel.
