NOISE REDUCTION TEST OF WORM HELICAL GEAR PAIR IN AUTOMOBILE ELECTRIC SEAT ADJUSTER
Aiming at the noise problem of the automobile electric seat adjuster
a pair of modified worm and modified helical gear was adopted for its main transmission system to reduce the meshing impact. The mathematical model was established
and several worms and helical gears with different modifications were processed. The noise test bench was built
and the acceleration spectrum of the automobile seat adjuster under the original models and different modifications were tested. Then the whole device’s noise reduction test was conducted with the optimized combination of tooth profile modification. The analysis results show that the appropriate profile modification of the worm and helical gear can effectively reduce the acceleration spectrum peak. With 0.04 mm and 0.02 mm modification respectively for the helical gear and the worm
the acceleration peak value of seat adjuster is significantly lower than that of the original product. The difference between the 6 sets of test products maximum noise and the standard products is within 1.6 dB
and the acceleration spectrum and acceleration peak of the experimental products are significantly reduced compared to the original product
which can verify noise reduction by the tooth profile modification of worm and helical gear pair is feasible.
