Camshaft adjusting device

A camshaft adjusting device, comprising:

• a variator, wherein the variator has an input shaft, which can be coupled to a crankshaft;
• an output shaft, which can be coupled to the camshaft;
• an adjusting shaft, which can be coupled to an actuator, wherein the variator forms an internal gear chamber, wherein the input shaft, the output shaft and the adjusting shaft are in operative connection with each other in an internal gear chamber;
• and,
• a lubricant supply unit for supplying the internal gear chamber with a lubricant;
• wherein:
• the lubricant supply unit is designed to form a lubricant sump, which is arranged radially outside of an axis of rotation, in the internal gear chamber;
• the lubricant sump covers at least one rolling bearing point;
• and,
• the lubricant supply unit has a lubricant feed line and a lubricant discharge line, wherein the lubricant discharge line comprises a lubricant overflow, wherein a radial expansion of the lubricant sump is defined radially inwards by the lubricant overflow in such a way that an outer ring of a rolling bearing is arranged in a region of the lubricant sump;
• and an inner ring is arranged outside of the lubricant sump.
