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 atNASA Lewis Research Center. Tests were conducted to 537kW
(720 hp) at 14 400 rpm. The effects of various operating conditions on spiral bevel gear steady state and transient
temperature are presented. Also, 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 attained in this study. The
results agreed well with each other for the cases compared and were no more than 10 percent different in magnitude.
