摘要:
A retainer is rotationally driven about a axis of a ball bearing, and convex areas having pockets provided therein along a ball pitch circle of the retainer and concave areas between adjacent pockets is detected by a sensor. Grease is discharged according to phases of the convex areas and concave areas in the rotationally driven retainer from a dispenser having grease discharge ports arranged to face an annular space.

A wind turbine generator includes a rotatable assembly comprising a first fixed part (200), a second, rotatable part (300) and a third part. The third part comprises a bearing system (420) for rotation between the first and second parts that includes inner and outer rings (430, 440) and a bearing element (450) arranged therebetween. A seal (600) is part of or attached to the second part for sealing a lubricant chamber (500) formed between the first part and the second part. At least one outlet (550) is formed in the second part for the lubricant to come out of the lubricant chamber.

The invention relates to a guide carriage for use with a guide rail extending in a longitudinal direction, wherein the guide carriage comprises a carrier body which can be movably guided in the longitudinal direction via at least one continuously revolving row of rolling bodies on the guide rail, wherein the carrier body has at least one end face which points in the longitudinal direction and on which a deflection assembly comprising a curved deflection channel for the rolling bodies is installed, wherein the deflection assembly (60) has at least one lubricating channel (70) for delivering lubricant, which has a U-shaped cross-section and which is covered by the end face of the carrier body, wherein the lubricating channel (70) is laterally delimited by a flexible sealing extension, which bears in a sealing manner against the end face of the carrier body. According to the invention, the deflection assembly (80) has at least one bypass channel (80a - 80c) in the form of a depression, said channel being covered by the end face of the carrier body, wherein the depression has a side edge which is interrupted by at least one first and at least one second opening (87; 88), wherein the first opening (87) is disposed adjacent to the sealing extension such that lubricant, which leaks past the sealing extension (71), arrives in the bypass channel (80a - 80c), wherein the second opening (88) is disposed on the outside surface of the guide carriage.
