Gear couplings are widely used as connecting elements that can allow axis displacements caused between two axes. The recent demands to gear couplings are as follow, they are the increase in load capacity, the increase in allowable shaft angle and the reduction in vibration and noise. In order to satisfy these demands, authors have proposed a method of new tooth contact analysis. In this paper,' the test gear couplings with the various profiles are used. The internal gears were manufactured by the CNC gear form grinding machine. The external gears were finished by the form grinding and the hobbing. The tooth contact tests were conducted under the axis displacements. The tooth contact patterns and sound levels were measured. As the results, the influence of tooth contact on the noise of the gear couplings almost was not found.
