OIL CONVEYING AND STORAGE DEVICE AND GEARBOX HAVING SUCH AN OIL CONVEYING AND STORAGE DEVICE

摘要

An oil conveying and storage device for reducing an oil level in an oil sump of a gearbox during operation of the gearbox includes a first piston mounted for executing a forward and backward movement, an intake chamber having a volume which varies in response to the forward and backward movement of the first piston, and a work cylinder. A thermal transfer wax is received in the work cylinder, and a second piston is received in the work cylinder and connected to the first piston. The second piston is moved in a temperature-dependent manner via the thermal transfer wax such that the volume of the intake chamber is increased as the temperature rises.
