The C-axis workbench of a hobbing machine plays a crucial role in gear manufacturing, not only affecting the machining ability and flexibility of the machine tool, but also directly related to the accuracy and quality of the machined gears.
[0003] During the installation process of the existing C-axis workbench of a hobbing machine, generally, the required installation tools, such as screwdrivers, wrenches, clamps, etc., and materials for fixing and adjusting are prepared first. The driving motor is placed at a predetermined position to ensure its alignment with the main shaft. Fixtures or other positioning tools are used to ensure the stability of the motor and perform preliminary fixing. Then, the gear pair is installed between the motor and the main shaft according to the design requirements to ensure accurate gear meshing.
