Journal pin oil supply for gear system and method for assembling

摘要

An example journal pin (80) includes a generally cylindrical body (101) disposed on an axis (P) having a supply passage (126). A first chamber (148a) and a second chamber (148b) are disposed in the generally cylindrical body (101) and are in fluid communication with the supply passage (126). A recess (154) on an outer diameter (100) of the cylindrical body (101) is in fluid communication with the first chamber (148a) and the second chamber (148b). The first chamber (148a) and second chamber (148b) are each radially outward of the supply passage (126) and include an outlet (153) to the recess (154). The first chamber (148a) and second chamber (148b) each have a first section (150) radially inward of a second section (152). A cross sectional area of the second section (152) is greater than a cross sectional area of the corresponding first section (150).
