NOISE REDUCTION TYPE ELECTRIC POWER STEERING APPARATUS CAPABLE OF REDUCING THE NOISE BY DECREASING THE INITIAL HANGING ANGLE

摘要

PURPOSE: A noise reduction type electric power steering apparatus is provided to maximize the gearing area at a point of two pitch lines to form the line contact.;CONSTITUTION: A noise reduction type electric power steering apparatus includes worms(11) coupling with each other, and a worm gear(10). An access groove is installed on the end surface of a saw blade for the worm gear for lubricating. The electric power steering apparatus transfers the output rotation of an electric motor(20) from the worms to the worm gear, and amplifies the output before applying to a shaft.;COPYRIGHT KIPO 2012
