<p>A speed reducer with frictional wheels for machines having a high rotation speed, of the kind which has a double planetary gear train. Said speed reducer uses, between a primary rotor (2) and the output shaft (3) of a driven rotor, the mechanical carry-over effects of rotary friction obtained by the rolling of frictional wheels which are strongly applied against each other. The applied forces are generated by the centrifugal force resulting from the orbital rotation of mass planet wheels (5) having mass (M), and spread from wheel to wheel up to the primary rotor (2) via outer planet wheels (6) provided with wheels (62) on the rim of which they rest. Said outer planet wheels (6) are arranged to roll on circular tracks (10) while resting on their supporting hubs (61). The rotary motion is harnessed by the side flanges (31) of a planet wheel support housing (30) and transmitted to the output shaft (3) which is integral with said housing.</p> |
