Abstract: The present invention relates to a pulley for a power steering oil pump which is connected to an engine by a belt to rotate a rotor of the oil pump and is rotated. Multiple cams having an eccentric unit protruding from one side and a support plate arranged in order for each cam to be formed in a circle are included. The eccentric unit is arranged to face the outside of the support plate to be touched on a belt and the cams are rotatable on the support plate in order for the length in which the eccentric unit and the belt are touched to be variable. According to the present invention, pulsation noise can be efficiently suppressed by changing the pulsation frequency of a resonance point as an external diameter is changed.

Abstract translation: 本发明涉及一种用于动力转向油泵的滑轮，其通过带连接到发动机以使油泵的转子旋转并旋转。 包括具有从一侧突出的偏心单元和为了使每个凸轮形成为圆形而布置的支撑板的多个凸轮。 偏心单元被布置为面对支撑板的外部以便在带上被接触，并且凸轮可以在支撑板上旋转，以使偏心单元和带被触摸的长度是可变的。 根据本发明，通过改变外部直径改变谐振点的脉动频率，可以有效地抑制脉动噪声。
