Abstract:

Results are shown of a large series of thermal calculations of a type of roller bearing very frequently used as gas turbine engine compressor rotor bearings. The calculations were performed with reference to two types of lubricant transformer oil and MK-8 oil widely used in gas turbine engines. The program was set up in such a way that the total losses incurred in driving each of the bearings were first estimated for a single value of the operating temperature and the radial load at various rpm regimes.
