Gears are among the most important mechanical elements in the construction of transmissions, vehicles and machinery. The requirements placed on these products in terms of power transmission or running smoothness continue to rise steadily.
Grinding is therefore one of the most important methods for meeting these high demands. For this purpose, KREBS & RIEDEL provides proven grinding tools for virtually all types of machines.
In continuous generative or profile grinding, the worm grinding wheel and workpiece rotate synchronously with one another while the workpiece is simultaneously moved past the worm grinding wheel at several traverses. The requirements on the kinematics of the machine are demanding. This method is economical for bulk production of small and medium-sized modules.
Gear shafts must meet high demands in terms of roundness and surface finish. Due to its high precision, grinding is still an economical finishing process.
Discontinuous generative or profile grinding is characterised by the fact that complete tooth spaces, or in the case of older machines just the flanks of the teeth, are ground by means of shaped wheels that are chamfered on both sides. The kinematics of the machine are less complicated; the machining method is intended for medium-sized batches, medium-sized and large modules, and varying ranges.
The grinding of spiral and bevel gears is a special process, undertaken primarily with grinding rings on grinding machines designed especially for this purposes by Klingelnberg and Gleason.
