Abstract:

The report presents the results of tests conducted to evaluate the performance of spiral bevel gears made from VASCO-X2 steel when they are operated without lubricating oil. Spiral bevel gears made from AISI 9310 steel and identical gears made from VASCO-X2 steel were run under load in a regenerative four-square test stand. The purpose of this testing was to evaluate the effect of material properties on the performance of main power gears in a nonlubricated loss-of-oil environment.
