を組み込んだことを特徴とするギヤポンプ。 A drive pump gear, a pair of bearings that support the drive shaft of the drive pump gear, a driven pump gear that meshes with the drive pump gear, a pair of bearings that support the driven shaft of the driven pump gear, a casing that accommodates these, and front and rear parts of the casing. It consists of a rear cover that seals each opening, and a front cover that has a through hole for the drive shaft that is equipped with a shaft sealing part. A portion of the liquid to be sent is introduced into each of the bearings as a lubricating liquid from the discharge port side of the casing via a groove, and at each joint surface of the rear cover and the front cover with the casing,
In the gear pump, a reflux groove is formed to connect the introduction groove of each of the bearing holes in a flow path, and the lubricated liquid is refluxed to the suction port side of the casing through each of the reflux grooves. A gear pump, characterized in that a thrust bearing housing is provided on the front cover adjacent to the shaft seal portion and concentrically with the drive shaft, and a rolling thrust bearing is incorporated inside the thrust bearing housing.
