Title:
LUBRICATING DEVICE
Document Type and Number:
WIPO Patent Application WO2004070231
Kind Code:
A3
Abstract:
The invention relates to a lubricating device for gear trains (10), especially for wind power stations, comprising at least two gear stages (16,18) that are disposed next to each other and are effectively interconnected, and a lubricant circuit (20) into which at least one filter unit (26) is mounted. In order to prevent stagnant resting zones for the lubricant from being created within the gear train housing comprising the gear stages while ensuring that the entire lubricant that circulates in the gear stages is fed to the filter unit in order to be drawn off and filtered thereby within predefined periods of time, the lubricant circulating inside the lubricant circuit (20) is discharged at one gear stage (18), is drawn off by means of the filter unit, and can then be fed to the other gear stage (16).
