A bearing arrangement includes a first anti-friction bearing including an Inner ring and an outer ring, a second anti-friction bearing including an inner ring and an outer ring, a first spacer element seated between the inner ring of the first anti-friction bearing and the inner ring of the second anti-friction bearing and including an oil supply channel which runs in a radial direction, and a second spacer element arranged between outer ring of the first anti-friction bearing and the outer ring of the second anti-friction bearing for adjusting a bearing prestress. The second spacer element Includes at least two curved pieces which are placed circumferentially in opposition to one another. The second spacer element extends in the radial direction such as to from a radial gap to the first spacer element and includes an oil supply channel which runs in the radial direction.

Adjustable bearing assembly, in particular for wind turbines

A transmission includes a first transmission stage, a feedthrough extending through the first transmission stage, and a first deflector designed to deflect a lubricant away from the feedthrough.

Transmission and method for operating a transmission

A planetary carrier arrangement Includes a planetary carrier, and a lubricant dispensing unit designed to dispense lubricant into the planetary carrier. The lubricant dispensing unit includes an axially elastically movable thrust ring designed to compensate an axial offset of the planetary carrier. The thrust ring has a side in facing relationship to the planetary carrier, with the side designed to include a lubricant pocket thereon.

Planetary carrier arrangement, planetary gear, drive train, wind turbine and computer program product

A planetary gear includes a central sun gear having external teeth, a ring gear having internal teeth, a planetary carrier having formed therein lubricant supply channels, and planet gears supported on the planetary carrier and having side cheeks engaging the internal teeth of the ring gear and the external teeth of the sun gear. A slide bush radially supports the planetary carrier and has radial outer and inner sliding surfaces, and an interposed shoulder surface, which bear flat upon a radial outer and inner bearing surfaces, and an interposed shoulder surface on an inner surface of the planetary carrier. An annular lubricant distribution channel is formed between the shoulder surfaces of the slide bush and the planetary carrier, with the lubricant supply channels feeding into the lubricant distribution channel on the inlet side and connected to the external lubricant supply via a lubricant supply channel formed in the slide bush.

Planetary gear

A gear train includes at least one planetary gear stage and one gear train stage. One end of a sun shaft of the planetary gear stage is concentrically surrounded by a hollow shaft of the second gear train stage. The sun shaft of the planetary gear stage is co-rotationally coupled to the hollow shaft by a denture clutch. A lubricant feed ring is arranged at a front face of the hollow shaft facing toward the sun gear of the planetary gear stage and has a cone-shaped passage opening, which has an internal diameter which decreases in the direction of the sun gear of the planetary gear stage, and concentrically surrounds the sun shaft of the planetary gear stage. At least one lubricant feed nozzle is aligned with a circumferential gap between the lubricant feed ring and the sun shaft of the planetary gear stage.
