  • Face hob hypoid gear tooth top-land radius by common chamfer tool
    Patent number: 8807890
    Abstract: A ring gear or pinion common outside chamfer tool and a common inside chamfer tool are disclosed. The common chamfer tools comprise a shank, a tip end and a chamfering edge. The shank is attachable to a gear cutter and has a tip end formed on the distal end thereof. The chamfering edge is positioned within the tip end and is configured to form a tooth top-land radius of multiple gear ratios. A method of designing a ring gear or pinion common outside chamfer tool and common inside chamfer tool for multiple gear ratios is also described.

  • Face hob hypoid gear tooth cutting by common blades
    Patent number: 8113750
    Abstract: A method includes selecting a first gear ratio and a second gear ratio. A first hypoid gear set defines the first gear ratio and a second hypoid gear set defines the second gear ratio. The first hypoid gear set includes a first ring gear that is formed with at least one first inside blade and at least one first outside blade coupled to a first gear cutter. The second gear set includes a second ring gear that is formed with at least one second inside blade and at least one second outside blade coupled to a second gear cutter. The method also includes identifying parameters of the first inside blade and the second inside blade, commonizing at least a portion of the respective identified parameters and forming at least one of a common inside blade and a common outside blade for forming a first modified ring gear and a second modified ring gear.

  • FACE HOB HYPOID GEAR TOOTH CUTTING BY COMMON BLADES
    Publication number: 20090097934
    Abstract: A method includes selecting a first gear ratio and a second gear ratio. A first hypoid gear set defines the first gear ratio and a second hypoid gear set defines the second gear ratio. The first hypoid gear set includes a first ring gear that is formed with at least one first inside blade and at least one first outside blade coupled to a first gear cutter. The second gear set includes a second ring gear that is formed with at least one second inside blade and at least one second outside blade coupled to a second gear cutter. The method also includes identifying parameters of the first inside blade and the second inside blade, commonizing at least a portion of the respective identified parameters and forming at least one of a common inside blade and a common outside blade for forming a first modified ring gear and a second modified ring gear.
