To counter complexity of spiral bevel gear geometry, this paper presents a mathematical model for calculating the steady bulk temperature field of spiral bevel gears based on the thermal transferring theory. Firstly, the mesh generation of finite element of the tooth of spiral bevel gear is discussed by using the 8-nodes three-dimensional finite element. Secondly, the authors develop the functional of the steady bulk temperature field of spiral bevel gear through the agency of variation principle and a method for calculating friction heat flow on the meshing tooth surface. Thus, the solution of steady bulk temperature field can be transformed into solving linear algebraic equations. Finally, this paper gives a calculating example and discusses the effect of a lot of factors （such as thermal physical parameters, geometric parameters and working conditions, etc.） on steady bulk temperature field of spiral bevel gear. The calculation results in this paper are in agreement with steady bulk temperature field of sp
