Description
Friction disk d is keyed to shaft 1, rotates about fixed axis A and is in contact with wheel 2 which is rigidly attached to shaft 4. Wheel 2 rotates about fixed axis C-C and can slide along this axis with shaft 4. Friction disk e is keyed to shaft 3, rotates about fixed axis B and is in contact with wheel 2. The transmission ratio from shaft 1 to shaft 3 is i₁₃=ω₁/ω₃=n₁/n₃=b/a where ω₁, ω₃, n₁ and n₃ are the angular velocities and speeds (in rpm) of shafts 1 and 3, and a and b are variable distances from axes A and B to the points of contact between wheel 2 and disks d and e (at the central plane of wheel 2). $3461$CF,IV$
