Saint-Gobain Abrasives has introduced its new Norton Abrasive Process Solutions (APS) Program which was established to help customers determine the optimal grinding or finishing solution for the application at hand, ranging from simple to complex, off-hand or automated, and for metal fabrication, production grinding and virtually any abrasives operation.
One way to implement the growing performance requirements for transmissions is by optimizing the surface finish of the gearing. In addition to increasing the flank load capacity and the transmittable torque, this also allows for improvements in efficiency. On Oerlikon bevel gear grinding machines from Klingelnberg, fine grinding
can be implemented efficiently in bevel gear production - even in an industrial serial process.
To achieve the requested quality, most gears today are ground. The usual grinding process includes treating the gear flank but disengaging before reaching the root rounding area. If the gear is premanufactured with a tool without protuberance, then at the position where the grinding tool retracts from the flank a grinding notch in the tooth root area is produced. Such a notch may increase the bending stresses in the root area, thus reducing the strength rating.
