Damage of the Surface Layer Gears in Grinding Process.

Abstract

The influence of the grinding process on the condition of the surface layer (SL) obtained by the treatment of the gear with grinding wheels Al2O3, CBN, GF, SG, alloy steels with different parameters of the grinding process and the type of cooling liquid – lubricant (CLL). The stress distribution at the surface layer, structural changes, secondary hardening, forgiveness SL and drastic damage–microcracs have been presented in comparative studies.
