Transmission accuracy analysis of worm gear and worm precision turntable based on multi-body theory
To improve the working precision of worm gear and worm precision rotary table,the mathematical model of error transmission of worm gear and worm precision turntable is established,which is based on the theory of multi-body system dynamics and combined with the structure and motion mechanism of the turntable.The influence of various errors on the accuracy is analyzed,and the error sensitivity analysis method of worm gear and worm precision turntable is put forward.Through the function differential method,the main error sources of the worm gear and worm precision turntable are identified.It provides a solid theoretical support for the subsequent error design and precision distribution,and promotes the industrial application of the precision turntable.
