Abstract

A sort of non-stage gear box, including: a driving face (29) freely rotative and supported on the main axis (21) of the gear box; the driven face (30) freely rotative and supported on the main axis (21) of the gear box; the cylinder support (31, 56) of free movement along the main axis (21) of the gear box; the twin-cylinder support (37) supported on the cylinder support (31, 56) along the cylindrical pilot line having the main axis (21) of the gear box as the center line; the twin-cylinder (39) fpormed by the first cylinder (40) and the second cylinder (41) for free rotation and supported onto said twin-cylinder supporting axis (37) to keep the first cylinder (40) against the the driving face (29) and the second cylinder (41) against the driven face (30); and the centrifugal mechanism (51) corresponding to the input rpm of the main axis (21) of the gear box for the cylinder support (31, 56) moving toward the axial line (L) of the main axis (21) of the gear box, featuring: said twin-cylinder supporting axis (37) being inserted into the bottom support hole (31 3) of the cylinder support (31, 56) by the main axis (21) of the gear box, preventing the cylinder support (31, 56) of the bearing (32) of the main axis 921) of the gearing box from falling.
