摘要

The gearbox has a planet carrier (5) provided with engaging toothed planet gears, where each gear comprises an internal ring and an external ring. A lubrication device (6) with a pump is driven by a shaft (4) of the carrier. The pump includes a housing having two lobes, each comprising a filling opening and a discharge opening for lubricant i.e. oil. A triangular movable cam (8) is movable in the housing by forming chambers of variable volume. An eccentric portion is fixed at the shaft of the carrier and movable with clearance in a central bore of the cam.
