DIFFERENTIAL MECHANISM Russian patent published in 1998 - IPC

FIELD: differential mechanisms for drives of transport facilities. SUBSTANCE: differential mechanism includes two output cam members revolving relative to common axis. Each has circular surface of cam with wave-shaped profile which includes pairs of mutually inclined surfaces. Many cam pushers with end surfaces are thrown into engagement with cam surfaces of output cam members. Parts of mechanism are so located that relative counter-rotation of output cam members causes axial sliding of cam pushers. Input member of mechanism makes pushers slide and move over circle relative to output cam members. These cam members have similar number of pairs of inclined surface on them. Mechanism is provided with at least two different types of cam pushers. Number of cam pushers is multiple of number of pairs of inclines surfaces. Multiplicity is integral number more than one. EFFECT: avoidance of torque during motion at turn in one direction and compared with motion at turn in other direction. 29 cl, 18 dwg
