DEVICE FOR INFINITELY VARIABLE CONTROL OF REDUCTION RATIO (VARIATOR) Russian patent published in 2010 - IPC F16H15/38 

FIELD: machine building.

SUBSTANCE: invention relates to rolling variator, particularly to control mechanism by roller orientation. Device of infinitely variable control of reduction ratio (variator) contains couple of rotating rolling path, installed for rotation around its common axis (218) of variator. Drive force is passed from one rolling path to the other by means of at least one roll (200), running by it. Connection between roll (200) and its carrier (214) provides roller precession relative to around axis (228) of precession, where it is defined relative to axis of precession and non-parallel to roller axis. Precession leads to changing of angle between axis (222) of roller and axis (218) of variator and corresponding to changing of reduction ratio. Carrier itself allows toothing (206), by means of which it is engaged with central tooth gear (212) and gear rim (214). Rotation of carrier (204) around axis of carrier serves to changing of axle orientation (228) of precession and accompanied by changing of reduction ratio of variator.

EFFECT: invention provides by means of control of displacement of carrier to change reduction ratio of variator.
