ENERGY GENERATING DEVICE (VERSIONS) Russian patent published in 2014 - IPC H02S10/00 H02S20/00 F16M11/10 F16C17/02 

FIELD: power industry.

SUBSTANCE: invention relates to renewable energy sources, and namely to an electric energy generating device from a renewable energy source including an articulated joint having a bearing. The energy generating device for the generation of electric energy from renewable energy sources includes a base, an energy conversion device connected to the base and the articulated joint between the base and the energy conversion device, which includes a bearing element having a housing comprising a composite material having a stiff material and a friction reducing material covering the stiff material; with that, the stiff material includes a material chosen of a group consisting of aluminium and stainless steel, as well as an intermediate material located between the stiff material and the friction reducing material; with that, the intermediate material includes at least one functional thermoplastic polymer having functional groups with the following formulas: , , , -COOH and/or -COOR, where radicals R are cyclic or linear organic radicals having 1 to 20 atoms of carbon, and includes a copolymer of ethylene-tetrafluoroethylene (ETFE), perfluoroalkoxy ethylene (PFA), a copolymer of tetrafluoroethylene perfluoro/methyl vinyl ester (MFA) and their combination. As per the second version, the energy generating device additionally includes an insert; as per the third version, it includes a bearing element connected to the articulated joint, has the housing including a composite material containing a stiff material and a friction reducing material covering the stiff material; with that, the bearing element has an atmospheric wear degree of not more than approximately 0.99 microns/h during at least approximately 15000 cycles of movement of the articulated joint; as per the fourth version, the friction reducing material has almost no visible defects after the salt fog resistance test is completed during at least 150 hours in compliance with the standard corrosion test ISO 9227:2006; as per the fifth version, the composite material of the bearing element has an average friction force that is not more than approximately 300 N during at least 15000 cycles of a vibration test.

EFFECT: invention shall improve reliability and durability of a bearing element.
