Contact Analysis of Helical Face Gears
Volume 6: 8th International Power Transmission and Gearing Conference, 2000Abstract This paper presents an analytical method developed to design and study the tooth geometry and contact characteristics of helical face gears. The tooth geometry is first defined while simulating the meshing of the face gear with the shaper used to cut it.

Design parameters for face gears
Journal of Mechanisms, 1971Abstract A general formulation to calculate critical dimensions such as the maximum practical outside diameter and the maximum face width of face gears in their general contact condition is presented. For the case of a face gear in mesh with an involute spur pinion on an intersecting orthogonal shaft, the necessary equations to calculate these ...

Technology of Gear Shaping of Face Gear and Experimental Studies
2010 International Conference on Digital Manufacturing & Automation, 2010Face gear is the major parts of helicopter transmissions for split torque equipment. The process generation of face gear is critical factors to prevent the face gear drive to be applied. A novice method is proposed for face gear generated by use of a general shaper. Face gear design and geometry were investigated that include tooth generation, limiting

In this chapter, the ever-increasing importance of face gear drives is first underlined, and short notes on their cutting processes are provided. The generation processes and geometrical elements of a face gear pair are then defined, and the basic topics of face gear manufacturing and bearing contact are given.

Some studies on hypoid face gears
Mechanism and Machine Theory, 1973Abstract Some of the geometric characteristics of a hypoid face gear in mesh with an involute spur pinion are analysed. These geometric characteristics include (a) the maximum diameter of the hypoid gear to avoid pointing of the teeth, (b) the minimum diameter for avoiding undercutting, (c) the contact ratio, (d) the field of contact and (e) the ...

Direct flank geometry calculation for face gears
Forschung im Ingenieurwesen, 2021Face gear drives with a 90° shaft angle represent special types of angular gear units. In these gearings, a spur or helical involute cylindrical pinion meshes with a face gear. They offer the possibility for high transmission ratios in small construction spaces. An involute pinion-type cutter typically generates the face gear.

Face Gear Width Prediction Using the DOE Method
Journal of Mechanical Design, 2008This paper deals with face gear design. The goal is to propose a simple formula for predicting the width of the wheel as a function of the main design parameters. A specific software was used to achieve this goal. This numerical tool is able to simulate the geometry and the quasistatic loaded behavior of a face gear.
