VAPOR LUBRICATION OF HIGH SPEED BALL BEARINGS
Abstract
Amine dithiocarbamates prepared from amine compounds of low boiling point produced extended running times, however, the amine dithiocarbamates prepared from morpholine were ineffective as a vapor lubricant. It is considered that this effect which is significantly different for amine carbamates may be associated with lower volatility of the amine dithiocarbamates. High temperature performance tests conducted under conditions of continuous running for p- dichlorobenzene resulted in running time increases in the range of 500%. The reduced running time under cycling conditions of operation may be caused by the corrosion products formed in large quantities on the test bearing surfaces during periods of shutdown. Dichloroaniline and bromocamphor produced short running times. Experiments conducted to date show that reduced lubricant properties are shown for camphor, naphthalene, morpholine carbamate, cyclohexylamine carbamate and dicyclohexylamine carbamate when substituting oxygen, carbon dioxide, argon and helium for nitrogen carrier gas.
