In gear hobbing, there are many factors that affect gear hobbing errors. In addition to external factors such as temperature, vibration, and deformation of the installation foundation, there are mainly the following aspects:

1. Geometric shape error of gear hobbing cutter 2. Geometric shape error of gear hobbing cutter and workpiece clamping 3. In gear hobbing machining, errors caused by vibration, thermal deformation, and force deformation of the entire process system of the machine tool, tool, and fixture workpiece 4. Geometric accuracy error of the machine tool 5. Transmission chain accuracy error of the machine tool, et

In summary, there are many reasons that can affect the errors in gear hobbing, and the situation is also complex. The main task of gear hobbing operators is to identify the main factors that affect gear hobbing errors. Through analysis and research, they can correctly identify the corresponding methods to eliminate their errors in order to produce more qualified products.

The main reason for the variation in the length of the common normal line is due to errors in the tool holder system, such as worm gear eccentricity, spindle eccentricity, etc. The manufacturing errors of the tool itself and the unstable installation of eccentric or inclined radial feed mechanisms are caused by the swing of the workbench, which makes the tool unstable

Solution: Repair and restore the accuracy of the tool holder system. Check and repair the radial feed mechanism. Adjust the workbench and let the tool check the installation of the tool
