GEAR UNIT LUBRICATION

摘要

A gear unit comprising a planet gear rotatable about a sun gear and supported by a planet carrier, said planet carrier comprising an annular formation for flow of lubricant and which is substantially concentric with the major axis about which the planet carrier is rotatable, and the gear unit comprising a housing having at least one lubricant supply position provided at a position radically aligned with said annular formation of the planet carrier as considered relative to said major axis about which the planet carrier rotates, and the planet carrier comprising flow paths for flow of lubricant from said annular formation to a planet gear bearing. The invention also discloses a method of lubricating a gear unit.
