Experimental and Analytical Assessment of the Thermal Behavior of Spiral Bevel Gears


An experimental and analytical study of spiral bevel gears operating in an aerospace environment has been performed. Tests were conducted within a closed loop test stand at 537 kW (720 hp) and 14400 rpm. The effects of various operating conditions on spiral bevel gear steady state and transient temperature are presented. A three-dimensional analysis of the thermal behavior was conducted using a nonlinear finite element analysis computer code. The analysis was compared to the experimental results. The results agreed within 10 percent.
