Experiment Research and Analysis of Transmission Error of Gears

摘要

Through testing the errors of spur gear and helical gears,transmission error curve of non-grinding gear is drawn.The effect factors on gear transmission error are found.The transmission error effect factors of all kinds of gear high-low frequency are analyzed.It is obtained that gear kinematic error is the evaluating guideline of transmission precision.Experimental results shows that error of gear axial offset and gear frequency period have less effect on gear transmission kinematic error.While gear backlash and face width direction error have more obvious effect on kinematic error.The results provides reasonable theory basis for determining gear cutting precision.
