Patent number: 10060415Abstract: A system for emergency lubrication, with a lubricant pump (113) and with at least one outlet opening (125) for delivering lubricant to at least a first lubrication point (107) of a transmission (101), in particular a transmission of a wind turbine. The system includes a first cavity (203), and the lubricant pump (113) is designed to convey at least some of the lubricant into the first cavity (203). The first cavity (203) is designed to store the lubricant intermediately and to act upon the intermediately stored lubricant with positional energy. In addition, there is a lubricant-conveying connection between the first cavity (203) and the outlet opening (125).Type: GrantFiled: October 24, 2014Date of Patent: August 28, 2018Assignees: ZF Friedrichshafen AG, ZF Wind Power Antwerpen N.V.Inventors: Roger Bogaert, Michiel Van Den Donker

Patent number: 7335128Abstract: A drive assembly for a wind turbine includes a rotor hub, a supporting structure, a planetary gear transmission unit having sun, planet and ring gears and a planet carrier. The ring gear is non-rotatably secured to the supporting structure. A main bearing rotatably supports the rotor hub and planet carrier relative to the ring gear and supporting structure. The drive assembly further includes two substantially independent force transmission paths for transmission of forces reacting with forces exerted by the wind turbine rotor hub. A first of the force transmission paths acts from the rotor hub via the main bearing to the supporting structure primarily for transmission of overhang load forces and bending moment forces and a second of the force transmission paths acts from the rotor hub via the planet carrier primarily for transmission of rotational forces.Type: GrantFiled: January 30, 2006Date of Patent: February 26, 2008Assignee: Hansen Transmission International NVInventors: Peter Flamang, Marcel De Wilde, Roger Bogaert
