FIELD: transport engineering. SUBSTANCE: transmission has driving and driven pulleys, ball member-satellite arranged for relative displacement and rotation around axes and engaging through equidistantly and radially arranged projections and cavities formed by surface of rotation with generating involute. It has also control member is form of gearshift mechanism with gear rack engaging through gear wheel and axle with gearshift lever. Working surfaces of pulleys are formed by surface of rotation. Cavities are located on working surfaces of driving and driven pulleys, and projections, on surface of ball member-satellite held in space by means of spherical strips. EFFECT: simplified design, enhanced reliability, enlarged range of setting of gear rations. |
