In order to improve load-carrying capacity and noise behavior, gears usually have profile and lead modifications. Furthermore, in gears where a specified tooth-flank load application direction (for drive and coast flanks) is a design enhancement, or even compulsory, the asymmetric tooth profile is a further solution. Nowadays, many gears need to be hard finished. Continuous generating grinding offers a very high process efficiency, but is this process able to grind all modifications, and especially asymmetric gears? Yes, it is!
This technical paper will report about all new possibilities of modifications with the continuous generating grinding method, such as:
– deviation free topological grinding (DFT),
– generated end relief (GER),
– noise excitation optimized modification (NEO),
– and asymmetric gears.
All of these modifications are indeed well-known in the gear industry. And, tooth grinding methods are already established (namely: profile grinding of asymmetric gears) to produce them. But now, they can additionally be produced with, for certain parts, the faster—and therefore more economic—continuous generating grinding method.
