Claims (1)
ポンプ吐出側に大径孔、吸入側に小径孔を有する
段付孔を穿設し、該大径孔に圧入されるスプライ
ンと該小径孔に嵌入する案内部を有する軸を該段
付孔に圧入してスクリユーポンプのロータと軸を
結合し、スプライン結合部にロータと軸を直径方
向に貫通する固定ピンを設けたことを特徴とする
スクリユーポンプのロータと軸の結合構造。 A stepped hole is drilled through the center of the light metal screw rotor and has a large diameter hole on the pump discharge side and a small diameter hole on the suction side, and the spline is press-fitted into the large diameter hole and inserted into the small diameter hole. The rotor and shaft of the screw pump are connected by press-fitting a shaft having a guide portion into the stepped hole, and a fixing pin is provided in the spline joint portion to pass through the rotor and the shaft in the diametrical direction. U-Pump rotor and shaft connection structure.
