ABSTRACT:
This method is for finish machining the teeth of rough machined bevel gears having longitudinally curved teeth where finish machining is undertaken subsequent to case hardening. To permit economical fabrication of such bevel gears at least in mass production, the bevel gears are ground as workpieces by a tool designed as a hypoid gear and provided with at least one abrading surface on tooth flanks of its toothing. The workpiece and the tool are brought into mesh and positively and synchronously rotarily driven in the ratio of their respective tooth numbers. Displacement of the tool axis relative to the workpiece axis as well as speeds of the tool and the workpiece are selected such that a relative sliding velocity arising between the tool and the workpiece lies within the range of conventional surface speeds for grinding. All concave tooth flanks of the workpiece or all convex tooth flanks of the workpiece or both are continuously ground in a single operation with a feed motion. The gear employed as the grinding tool exhibits curved helical bevel gear teeth. These gear teeth are provided with an abrading coating on their tooth flanks. The tool is arranged in axial displacement relative to the workpiece. In order that both the workpiece and the grinding tool can be driven synchronously at the requisite rotary speeds, both the tool and the workpiece are each connected to a respective electric motor and the two electric motors are interconnected by a so-called "electric shaft".
