A VIBRATING RIG TEST FOR RAILWAY BEARING GREASES

A test rig utilizing a standard reaction type vibration test machine was developed to determine the consistent stability of grease lubricants in auti-friction bearings. This program was undertaken in view of the ever increasing demands upon greases in railway service and also the lack of direct correlation among performance characteristics obtained through existing standardized bench tests, full scale rotational tests lacking vibration, and those characteristics displayed in the field. General performance of the products tested appeared to be insensitive to the parameters of vibration within the range of parameters occurring in service. A 48 hours test which subjects the test cartridge to 4 G's at 38 cps with the grease bulk temperature thermostatically controlled at 180 F emerged as the condition which yielded results duplicating field service conditions.
