Measurement of Static Tooth Fillet Strain and Transmission Error of a Cylindrical Worm Gear

원통형 웜기어의 정적 이뿌리 변형률 및 전달오차 측정

Using a cylindrical worm gear under the actual condition of static loading, tooth fillet strains and transmission errors have been measured. The maximum strain occurs on the filet region of the center of the 1st mating tooth. Tooth fillet strain changes most sensitively according to the variations of the center distance and recess side eccentricity than the access side eccentricity. Even the no-backlash worm gear shows the transmission errors.
