Gear coupling is composed of one hub and one sleeve. The hub of gear coupling is external gear that has barrel shape and the sleeve is internal gear. External gear of barrel shape is called as pinion in this paper. In the research process of tooth contact of gear coupling, authors measured the tooth profile of pinion and found that tooth profile possibly has deviation of helix angle and pressure angle. We guess that this might be theoretical deviation caused on hob cutting, because pinion in gear coupling has barrel shape. This paper analyses theoretically the profile of gear coupling-pinion, then fits the 3-D measuring data to the theoretical profile. The results show that deviations of helix angle and pressure angle of the pinion almost correspond to the theoretical deviation of hob cutting.
