FIELD: machine building.
SUBSTANCE: tooth variator consists of case, of driving (1) and driven (2) truncated cones with teeth of variable width and similar height along length mounted on shafts, of positioned between cones complex idler including internal and external relatively travelling sleeves. The internal sleeve of the idler is integral. The external sleeve of the idler is complex and includes a bushing and teeth made in form of flexible arc-shape elements rigidly fixed on the bushing. Axle (9) of a screw mechanism of progressive motion of the idler (3) is parallel to generatrices of truncated cones.
EFFECT: simplified design and expanded process functionality of variator.
