surely this would be technically feasible with a mechanism similar to a bearing [1] but with teeth on the inner and outer and cogs in place of the bearings (through which the shaft would pass)? the difficulty of course would be to tune the teeth so the outer turns at the same rpm as the inner.. ..though i get the implication of design vs engineering [1] http://upload.wikimedia.org/wikipedia/commons/thumb/1/16/Bal... ) |
