Abstract
The invention discloses an automobile engine fuel injection pump belt pulley with high wear resistance. The automobile engine fuel injection pump belt pulley component comprising a body made by powder metallurgy comprises a pulley body and a pulley edge coaxial to the pulley body. Pulley teeth are arranged on the outer wall of the pulley edge and are coaxial to the central hole of the pulley body. The tooth side faces of the pulley teeth are transitioned to the teeth top faces and tooth roots through fillets. The outer walls of the pulley teeth are provided with wear resistant composite layers. The invention further discloses a manufacturing method of the automobile engine fuel injection pump belt pulley with high wear resistance. The method includes blending, mixing, pressing, sintering and finishing procedures. Material utilization rate is high, time and material cost are saved, stress concentration on the pulley teeth is reduced significantly, wear resistance of the automobile engine fuel injection pump belt pulley is improved significantly, and service life of the automobile engine fuel injection pump belt pulley is prolonged significantly.
