FIELD: mechanical engineering, namely, stepless mechanical transmissions, possible use in drives of various mechanisms and machines for stepless adjustment of speed of rotation of working organs from zero to given value.
SUBSTANCE: driving element of stepless transmission is made in form of resilient coil, capable of changing step by means of control mechanism. Resilient coil is represented by a split collar 6, positioned between barrel of driving shaft and external cylindrical bushing of control mechanism. Stepless transmission also contains adder of movements, made in form of toothed transmission, driven link of which is held on driven shaft 16, and driving links are kinematically connected through sleeves and driven element, made in form of at least two spring-loaded pushers 19,20, with split collar 6.
EFFECT: expanded functional capabilities of stepless transmission, ensures smooth change of speed and possible setting of zero speed, and also ensured continuous movement of driven element.
