Gear steps 1-14
The Rohloff SPEEDHUB 500/14 gear unit, consists of three in line interconnected planetary gear assemblies #1, #2 and #3. Input is delivered by the sprocket, which is screwed to the driver which connects to gear assembly #1. The planetary gear assemblies #1 and #2 are identical, except that they are laterally reversed, sharing together the planet carrier (1-2). A total of seven gears are produced by these first two assemblies. The further connection of gear assembly #3, which serves as a reduction gear, doubles the gear count to 14. The output drive is delivered from planet carrier #3 to the hub shell via 9 nylon coupling pins located in specially machined pockets.
In all texts and illustrations, parts corresponding to their affiliation with gear assemblies #1, #2 or #3, can be identified by the supplement (1), (2) or (3).
