1. Excessive rake angle of the gear hobbing tool: Excessive rake angle of the gear hobbing tool may result in excessive cutting force during the cutting process, leading to tooth profile errors.

2. Transmission chain error: Gear motion error, axial and radial circular runout exceeding tolerance in the transmission chain can all affect the accuracy of tooth profile.

3. Eccentric installation of workpieces and cutting tools: Eccentric installation of workpieces and cutting tools can cause instability during the cutting process, thereby affecting the accuracy of tooth profile.

4. Exceeding the runout of the workpiece and tool: Exceeding the radial circular runout of the workpiece spindle and tool spindle can affect the accuracy of the tooth profile.

Specific reasons and solutions:

Excessive rake angle of the gear hobbing tool: Adjust the rake angle of the gear hobbing tool to ensure that it does not generate excessive cutting force during the cutting process.

Transmission chain error: Check and adjust the gear motion error in the transmission chain to ensure that the axial and radial circular runout are within the tolerance range.

Eccentric installation of workpieces and tools: Reinstall the workpieces and tools to ensure their stability during the cutting process.

Excessive runout of workpiece and tool: Check and adjust the radial circular runout of the workpiece spindle and tool spindle to ensure it is within the tolerance range.
