This paper describes the method to calculate the load distribution and the tooth root stress of the Gleason type spiral bevel gear. The tooth form of spiral bevel gear was determined according to the gear generating principle of the spiral bevel gear. The tooth deflection and the tooth root stress due to a concentrated load at the arbitrary position on the tooth-working flank were calculated by the three-dimensional finite element method. On the basis of the calculation results, the approximate formulas for the tooth deflection influence function and the bending moment influence function on the bevel gear tooth were derived. Next, with the approximate formulas the load distribution on the tooth-working flank and the tooth root stress were calculated. Furthermore, the calculated tooth root stresses were compared with measured values, and the validity of the present calculation method was examined.
