Abstract
The utility model relates to a piston mud pump bearing seat, which comprises a driving shaft bearing seat and a driven shaft bearing seat. The bearing seat is arranged on the two sides of a casing on a power end of the mud pump, and is used to support the rotations of a driving shaft and a driven shaft. The driven shaft bearing seat comprises a bearing base and a bearing cap, which are fixedly connected, wherein the bearing base and the bearing cap are semi-toroidal structure, a ring-shaped lap joint port which is used to overlap with the casing of the slurry pump is arranged on the outer side of the semi-toroid of the bearing base, axial projections are arranged on the two ends of the semi-toroid of the bearing base, and axial grooves which are matched with the axial projections are arranged on the two ends of the semi-toroid of the bearing cap. The driving shaft bearing base is a ring-shaped structure, and is provided with a ring-shaped lap joint port which is used to overlap with the casing of the mud pump is arranged on the outer side of the toroid of the driving shaft bearing base. The bearing bases are individually manufactured and processed, and are welded integrally with the casing of a drill pump, which reduces cost and manufacture difficulty, saves materials and reduces cost.
