Abstract

A lubrication system for a pitch bearing of a wind turbine includes a lubricant for lubricating contact surfaces between an outer race, an inner race, and a plurality of rolling elements of the pitch bearing. Further, the lubrication system includes a lubricant inlet formed into a first side of the inner race and an inlet seal for sealing the lubricant inlet so as to prevent the lubricant from leaking from the lubricant inlet. Moreover, the lubrication system includes a lubricant outlet formed into an opposing, second side of the inner race and a lubricant collection container arranged adjacent to and in fluid communication with the lubricant outlet and mounted to the inner race. Thus, during operation of the wind turbine, at least one of a slope of the pitch bearing, gravity, and a centrifugal effect cause the lubricant to flow throughout the pitch bearing to lubricate the contact surfaces without exiting a closed volume defined by the inlet seal(s) and the lubricant collection container(s).
