TOROIDAL VARIABLE-SPEED DRIVE UNIT

摘要

FIELD: machine building. ^ SUBSTANCE: variable-speed drive unit comprises master and slave toroidal wheels (2, 3) and roller (6). Their generatrices are made in the form of convex and concave curved surfaces. Due to arrangement of generatrices of working surfaces in master and slave elements in accordance with a certain dependence, area of friction pairs contact is increased. ^ EFFECT: improved kinematic characteristics of variable-speed drive unit. ^ 3 dwg, 1 tbl
