Greaseless hanger assembly for a railcar door

摘要

A railway car door (10) includes a substantially planar door (14) and a pair of elongated support members (18) which are rotatably mounted to the door. A drive mechanism (50) is operatively associated with the railcar door for imparting rotational forces on the support members. A pair of greaseless crank (22b) and roller hanger assemblies (26) movably support the door member on a track (24). Each crank assembly includes a crank pin (96) having a shaft portion 100 with a peripheral recess (114) closely embraced by a self-lubricating sleeve (116). Each roller hanger assembly includes a housing (102) having a well or channel (106) with at least one self-lubricating annular member or washer (120) disposed at the bottom wall (122) thereof. The peripheral recess (114) of the crank pin shaft portion with sleeve (116) are closely rotatably received in bore or channel (106) with the outer terminal end face (124) of the crank pin shaft portion placed in engagement with the at least one annular member or washer (120).
