Planetary gear has holes for supply of lubricant formed in at least one planet wheel axis, and at least one cheek of carrier is connected to oil retainer to create lubricating passage from which lubricant reaches bearing through holes

摘要

The planetary gear has an externally toothed, bearing mounted planet wheel (6) with the planetary wheel pivots (4) installed in a carrier system, and the bearing on its axial ends are covered by the cheeks of the carrier system an/or casing sections. Holes for the supply of lubricant are formed in at least one planet wheel axis, and at least one of the cheeks is connected to an oil retainer to create a lubricating passage (7a) from which lubricant reaches the bearing through the holes. A Nilos ring is used as the oil retainer and has an axially central hole, the diameter of which is larger than the outside diameter of the driving motor shaft.
