Internal Generating Gear Grinding is a hard finishing process developed by the NIDEC MACHINE TOOL CORPORATION in Japan. It is a grinding process like generating gear grinding but for the internal teeth of a ring gear.
Today, industry is mostly using crossed helical gears with steel worm and plastic wheel. The behavior of plastic in gears has been studied in scientific work.
Cylindrical involute gears are measured on a broad variety of coordinate measuring machines. The quality inspection includes the measurement of profiles, helices and pitch points on the spur or helical gear flanks.
This study presents some guidelines to decrease the non-demanded excitations from the bearings and therefore to optimize the NVH characteristics of a gear reducer.
