WAVE PLUNGER REDUCTION GEAR Russian patent published in 2010 - IPC F16H1/00 F16H35/10 

FIELD: engineering industry.

SUBSTANCE: wave plunger reduction gear includes movable rigid gear wheel (13), wheel interacting with it, wave generator (2) with cylinders (3) and radial channels (6) uniformly distributed in a circumferential direction, which connect each cylinder to central hole (7). Distributor (8) made in the form of shaft with working medium supply and discharge cavities (9) is installed in central hole (7). Wheel is made in the form of ring-separator (15), in the slots of which there located are radially movable prismatic plungers (14). In symmetric slots of plungers there installed is non-extendable flexible element (16). On shaft of distributor there eccentrically installed and offset in two diametrically opposite directions relative to wave generator axis are discs (22) interacting with plungers. The straight line along which discs (22) are offset, coincides with symmetry axis of distributor supply cavity. When discharging working medium from high pressure main line, plungers (14) come into contact with discs (22) and remain fixed in radial direction, thus maintaining engagement with movable wheel (13) and gear clutches (1). As a result, movable wheel (13) is reliably fixed against rotation.

EFFECT: improving operating reliability of reduction gear.
