A cooling oil guiding device for rotating component parts. An annular oil channel extends in radial direction and cooling oil can be supplied from radially inward. The oil channel is partially open radially outwardly. A sealing area is provided in a radially outer area of the oil channel having blocking elements and outlet elements. The blocking elements are arranged radially inwardly of the outlet elements and have at least two passages in radial direction which are distributed along the circumference. Outlet channels aligned with the passages and inlets which are disposed between the outlet channels in circumferential direction are formed by the outlet elements. An annular channel is provided between the blocking elements and the outlet elements to connect the inlets with the outlet channels and passages, respectively.

Cooling oil conducting element and drivetrain comprising same

Bearing arrangement with a bearing having an outer bearing race; a machine element with a cylindrical cutout receiving and securing the outer bearing race; and a circumferentially constructed groove adjoins a first axial side of the cylindrical cutout and extends radially outward to receive a locking element for securing the outer bearing race at the first axial side of the groove; an annular locking element having an inner diameter which is larger in a mounting state than in a securing state. The locking element is partially guided in the constructed circumferential groove to secure the outer bearing race at the first axial side in the securing state; and a securing device cooperates with the locking element to secure a changed state of the locking element; and the securing device secures the locking element from an outer side of the machine element opposite the first axial side of the cylindrical cutout.

Bearing arrangement for a machine element

A cooling oil guiding device for a clutch actuatable by an axially movable piston. The piston is radially inward of the clutch, and separates a pressure space and a compensation space. The compensation space is delimited by an axially stationary compensation space cover and a seal cover coupled to the piston. The compensation space cover and the seal cover axially overlap radially outwardly and are axially movable relative to one another via a sealing element. An overflow opening connects the compensation space to an oil channel in the seal cover between the seal cover and the piston, the oil channel opens radially outward. A control edge is provided at a component part axially immovable relative to the piston, by which an oil flow exiting from the oil channel is guided through the clutch when the clutch is closed and is guided past the clutch when the clutch is open.
