Abstract
A lubricating device for gear trains (), especially for wind power stations, includes at least two gear stages () that are disposed next to each other and are effectively interconnected, and a lubricant circuit () into which at least one filter unit () is mounted. To prevent stagnant resting zones for the lubricant from being created within the gear train housing including the gear stages, while ensuring that the entire lubricant that circulates in the gear stages is fed to the filter unit to be drawn off and filtered within predefined periods of time, the lubricant circulating inside the lubricant circuit () is discharged at one gear stage (), is drawn off through the filter unit, and can then be fed to the other gear stage ().
