Tooth profile analysiis of circular-cut, spiral-bevel gears [PDF]
An analysis of tooth profile changes in the transverse plane of circular-cut, spiral-bevel crown gears is presented. The analysis assumes a straight-line profile in the mid-transverse plane.

Crack Propagation in Tooth Root: A Comparison Between Pulsator Test and Running Gears
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 12, Page 5181-5194, December 2025.ABSTRACT Tooth root fatigue fracture is a critical gear failure mode in which the tooth root breaks because of the repetition of bending load. The most widely adopted procedure for evaluating root strength is through pulsator testing. However, this test method does not present gears in meshing conditions. When focusing on the limited‐life region of the

Geometry Definition and Contact Analysis of Spherical Involute Straight Bevel Gears
International Journal of Industrial Engineering and Production Research, 2012 A practical application of the spherical involute surface to the forged straight bevel gears is provided and demonstrated in this work. Conjugate (pure involute) theoretical surfaces are developed from the input design parameters.

An envelope shaping method for huge straight bevel gear [PDF]
SN Applied Sciences, 2019 An envelope shaping method of machining huge straight bevel gear is proposed in this paper. This method can achieve higher machining precision and efficiency. Firstly, the geometric characteristic of the tooth surface is analyzed. Then an envelope shaping principle is given. Based on this principle, the mathematical model of machine motion is built. In

Contact stress analysis of spiral bevel gears using nonlinear finite element static analysis [PDF]
A procedure is presented for performing three-dimensional stress analysis of spiral bevel gears in mesh using the finite element method. The procedure involves generating a finite element model by solving equations that identify tooth surface coordinates.
