Rail lubrication application system

摘要

A lubrication applicator presses a block of solid lubricant against the flange of a locomotive wheel. An applicator nozzle loosely fits over the body of the applicator and lightly engages the block of lubricant to bridge the gap between the body and the wheel. The applicator is supported by a main bracket fixed to an unsprung portion of the locomotive truck, such as a journal box or a traction motor, and an adjustable bracket which establishes a good attitude of the applicator and is movable radially of the wheel to accommodate wheels of different diameters. A bracket attached to a journal box fits in a restricted space between the truck frame and the wheel and comprises a plate with upper and lower channels attached to opposite sides to provide strong and light structures subject to minimal inertial loading in a severe vibrational environment. To lessen the inertial forces the brackets angle upward (rather than horizontally) to position the applicator within about 45 DEG of the vertical plane of the wheel.
