Description
Summary:碩士 === 正修科技大學 === 機電工程研究所 === 95 === This paper studied and improved a three stage planetary gear winch with double circular-arc gears. Tooth contact analysis and bending stress were studied by chinese standard double circular-arc gear. The contact stress can be reduced largely because the relative curvature of tooth of double circular-arc gear is smaller than involute gear. The winch with double circular-arc gear can sustain a larger torque than the winch with other type of gear, therefore the size of the winch can be reduced too. Tooth contact stress and bending stress were studied in this paper. Finally, we developed a new tooth profile for double circular-arc gear. This paper improved original double circular-arc gear, developed a new design and applied analysis software to this drive. The processes of design and manufacture were more simple. The advantage of the new drive was confirmed.
