Modal Analysis of Aeronautic Spiral Bevel Gear in the Temperature Field

The temperature of the bevel gear tooth surface will increase greatly because its special structure. Modal is characteristic reaction In order to design and manufacture higher quality aerial gears, it necessary study modal gears under action field. Firstly, a field calculation model established according heat transfer theory. Then, based on traditional linear theory, analysis influence was considering rotational speed stiffness. Based model, driven certain aviation carried out. It can be seen from results that has great stiffness, positive negative effects are related direction centrifugal force. Secondly, inhomogeneity distribution also affects natural frequency then When work together, pitch shape changes most, so consider as an influencing factor in gears.
