Measurement and traceability of transmission error of gear hobbing machine tool based on gear harmonic frequency.

At present, the machining accuracy, transmission error chain error measurement and optimisation design of gear hobbing machine transmission control system are facing the bottleneck of development. Based on this, this research takes the rotary device of the gear hobbing machine tool as the research object, and creatively analyses the measurement method of the transmission error of the gear hobbing machine tool. This method can obtain the variation law of the transmission error of the gear hobbing machine, and identify the transmission error type of the gear hobbing machine. The transmission error detection platform of gear hobbing machine is built, and the transmission error measurement of gear hobbing machine is completed. The research results provide a new development idea and research direction for improving the machining accuracy of gear hobbing machine tools, and effectively solve the problem of transmission error traceability of gear hobbing machine tools.
