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 (30) is discharged at one gear stage (18), is drawn off by means of the filter unit, and then can be fed to the other gear stage (16).
Lubricating device for gear trains (10), especially for wind power stations, with at least two gear stages (16, 18) which are mounted next to one another and which are dynamically connected to one another, and a lubricant circuit (20) to which at least one filter unit (26) is connected, characterized in that on one gear stage (18) the lubricant which is circulating in the lubricant circuit (20) is drawn off, cleaned by the filter unit (26), and can then be supplied to the respective other gear stage (16).
The lubrication device as claimed in 1, wherein at least one gear stage (16) with the lubricant supply (38) is a planet gear and at least the other stage (18) with the lubricant removal (40) is a spur gear.
The lubrication device as claimed in 1, wherein the lubricant removal (40) consists of a suction device and the lubricant supply (38) consists of an injection device, and wherein in the gear housing (10) for the respective gear stage (16, 18) the indicated devices (38, 40) mounted diagonally opposite one another extend through the upper and lower area of the housing (10).
