Study on Internal Face Gear [PDF]

open access: yes, 1969
One of the principal design problems in the internal face gears is to calculate the face width of the internal face gears. The maximum outside diameter of the internal face gear is limited by the point where the top land of the tooth narrows to a knife ...

Study on Involute Face Gear [PDF]

open access: yes, 1970
One of the principal design problems in the face gears is to calculate the face width of the face gears. The maximum outside diameter of the face gear is limited by the point where the top land of the tooth narrows to a knife-edge, and the minimum inside

A Numerical Gear Rolling Test Method for Face-Hobbed Hypoid Gears

open access: yesApplied Sciences, 2023
A numerical gear rolling test (NGRT) method for actual tooth surfaces was proposed. The non-uniform rational B-spline (NURBS) fitting method was adapted to reconstruct the actual tooth surface, and the instant meshing point as well as the transmission error of two meshing gears were solved. The instant contact ellipse boundary of each meshing point can
