LIFTING MECHANISM Russian patent published in 2019 - IPC F41G5/14 

FIELD: machine building.

SUBSTANCE: lifting mechanism comprises a housing, an electric motor, a planetary gearbox as the first stage of the mechanism, a conical transmission as a second stage and an output stage with a luff-picking device consisting of a gear and a sector. Sector is made split, two parts of which are connected to each other by means of plate elastic elements, planetary reduction gear is made according to kinematic diagram, comprising two crown wheels, satellites are made with two-crown teeth with different number of teeth on rims of one satellite and are installed in common carrier so that each rim engages with corresponding crown wheel, wherein planetary gearbox input link is made up of sun wheel while its outlet is made up of second crown wheel. Note here that first crown wheel is fixed part of the housing. Lifting mechanism is made in single sealed housing in the form of monoblock.

EFFECT: reduced weight and dimension parameters, improved operational characteristics and safety during operation due to introduction of protection of output stage of drive.
