Fillet Geometry of Ground Gear Teeth
The article "Fillet Geometry of Ground Gear Teeth" appeared in the January/February 1989 issue of Gear Technology.
This article investigates fillet features consequent to tooth grinding by generating methods. Fillets resulting from tooth cutting and tooth grinding at different pressure angles and with different positions of grinding wheel are compared. Ways to improve the final fillet of the ground teeth with regard to tooth strength and noise, as well as the grinding conditions, are shown. "Undergrinding" is defined and special designs for noiseless gears are described.
