STRUCTURE FOR REGULATING AXIAL DIRECTION IN EPICYCLIC REDUCTION GEAR

摘要

PROBLEM TO BE SOLVED: To regulate position of a carrier pin and (plural) epicycle gear(s) supported by the carrier pin in an axial direction with a small part number, a simple method, and causing no new troubles. SOLUTION: A ring shaped axial plate 94 is assembled in a vicinity of an end surface of the carrier pin 84 of a front stage epicycle gear mechanism Sp of a casing. A part of the bearing 92 of an epicycle gear 74 exposes from the axial plate 94. A small gapΔS1 allowing oil to flow in is maintained between the end surface of the carrier pin 84 and an opposing surface in a carrier pin side of the axial plate 94.
