Abstract
Contact ratio (CR) and transmission error (TE) are two significant indices for gear tooth strength and dynamics. This work investigated the CR, contac t teeth (CT) and TE of a helical gear pair, composed of an involute pinion and a modified circular-arc gear. Point contact and built-in parabolic TE a re obtained due to the modification of the gear's tooth profile. Tooth cont act analysis (TCA) is applied to determine the TE as well as the CR of the proposed helical gear set under various assembly condition. The effect of g ear design parameters on the CRs and TEs are also investigated in numerical examples.
