DESIGN OF ROTARY DEVICE AND CORRESPONDING ROTARY DEVICE, AND LOGGING MACHINE Russian patent published in 2020 - IPC B66C3/00 

FIELD: timber Industry.

SUBSTANCE: invention relates to rotary device for logging machine. Rotary device comprises first inner housing part (12) comprising first channels (26) arranged in first inner housing part (12), for directing working medium through first inner housing part, second outer housing part (14), located at least partially around first inner housing part (12) with possibility of rotation, comprising connections (28) fixed on second outer housing part (14), second channels (30) for directing working medium from first channel (26) to connections (28), comprising two ends (16.1 and 16.2) of axial channel (16) for guiding electric conductors (56) through first inner housing part (12), support means (20), intended to enable rotation of second outer housing part (14) relative to first inner housing part (12) and vice versa, and suspension means (90) for suspending structure (10) of rotary device (1) on boom (2). Structure (10) includes fasteners (22) for coaxial attachment of rotary device (24) on structure (10) for transfer of torque. In structure (10) there is axial channel (16) containing electrical conductors (56), passing from suspension means (90) through structure (10), and rotary device (24) attached thereto.

EFFECT: possibility of passage of working medium flow and electric conductors through rotary device.
