ACTUATOR MECHANISM GEARHEAD Russian patent published in 2009 - IPC F16H13/08 F16H25/06 

FIELD: machine building.

SUBSTANCE: invention refers to the sphere of machine building and enables conversion of motion types. The actuator mechanism gearhead is composed of a wave generator (6), roller bodies (7) and (11), a wobble plate (13) and a crown (10) mounted onto two coaxially positioned shafts, the input one (1) and the output one (2). The roller bodies (7) and (11) are installed inside separators (8), (12) and fixed to prevent their axial and/or angular displacement. The generator (6) has a shaped butt-end groove interacting with the roller bodies (7). On the butt end surface of the crown (10) there is also a groove arranged interacting with the roller bodies (11). The roller bodies (7) and (11) interact with the wobble plate (13). The plate (13) is locked with the help of a spherical support (14) freely fit onto the shaft (2). If viewed in coaxial cross section inside the crown (10) groove there are epicycloids arc shaped channels arranged for the roller bodies (11) slideless rolling. If viewed in axial cross section the crown (10) groove shape profile is identical to that of the roller bodies (11). Numerically the roller bodies (11) do not match the arcs.

EFFECT: increase of the gearbox load capacity and performance combined with minimisation of the device weight and dimension parameters and enables the device long-term adjustable and maintainable operation under widely varying environmental conditions.
