METHOD OF TORQUE TRANSFER AND VARIATOR TOOTH GEAR Russian patent published in 2010 - IPC F16H3/42 

FIELD: machine building.

SUBSTANCE: in disclosed tooth gear torque from driving shaft (3) to driven shaft (4) is transmitted with at least one tooth gear. Gear wheels (1, 2) of the said gear can slide along their proper shafts without relative rotation and have spiral teeth with random cross section. Depending on load applied to the driven shaft at any moment of torque transfer the meshing point travels along generatrices so, that increase of diametre and incline angle of teeth of one gear respond to decrease of diametre and incline angle of teeth of another gear.

EFFECT: expanded arsenal of technique.
