ORIENTATION-FREE PLANETARY PIN FOR LUBRICATION OF PLANETARY BEARINGS

摘要

A planet pin for use in a planetary gear system and a gear system including a planet pin are disclosed. The inventive planet pin provides a plurality of radial passages in fluid communication with an axial passage which can advantageously eliminate, or substantially reduce, the need to orient a planet pin in a planetary gear system.

主权项

1. A planetary pin for use in a planetary gear system, the planetary pin comprising:
a cylindrical body having an axial passage defined by an inner cylinder wall and a wall thickness between the inner cylinder wall and an outer cylinder wall; and a plurality of radial passages through the wall thickness configured such that axes of radially adjacent ones of the radial passages are offset by less than 180° when viewed along an axis of the axial passage,wherein the plurality of radial passages provide a corresponding plurality of fluid paths between the axial passage and the outer wall.
