ABSTRACT:
A frictionally gearing apparatus. This apparatus comprises two shafts accommodated in a cylindrical casing, extending in opposite directions or in a same direction reaching out of said casing, said shafts being employed for the input and the output either fixedly or in alternation. Said shafts each has a rotary object confronting each other within said casing, said rotary objects varying in diametrical length and each forming a friction surface at their confronting portions, further a plurality of frictionally-surfaced globular members of a same size diametrically measuring next to the bigger rotary object being provided between the afore-mentioned rotary objects so as to make rotational, frictional contacts simultaneously with said rotary objects thereby enabling the increase or decrease of the input rotation through its two-step transmission to the output via said rotary objects and said globular members.
