[0002] Gears refer to mechanical components with gears on the rim that continuously mesh to transmit motion and power. Thin-walled gears are ring gears with thinner walls than their own size and disc gears with smaller wheel widths. When processing thin-walled gears, the clamping fixture of the lathe is generally a three-jaw chuck, which fixes the thin-walled workpiece on the three-jaw chuck and then processes the workpiece with a tool.
