Problems solved by technology

[0002] At present, due to the vertical arrangement of the crankshaft of the vertical axis engine, the axial direction of the oil pump is in the vertical direction, and the driving gear and the driven gear are affected by the gravity of the gears. The oil pump structure arranged in the horizontal direction cannot meet the reliability requirements of the oil pump.

Abstract

The invention provides a vertical-shaft-arranged oil pump structure which comprises an oil pump body and a flange plate. The bottom of the oil pump body is fixedly connected with the flange plate; the oil pump body is internally provided with a driven gear, a driven shaft, a driving shaft and a driving gear; the driven shaft and the driving shaft are supported by shaft holes of the oil pump body and the flange plate; the driving gear is installed outside the driving shaft; the driven gear is installed outside the driven shaft; the driving shaft is connected to a transmissionsystem of an engine; an oil inlet and an oil outlet are formed in the two ends of the oil pump body correspondingly; and an oil inlet cavity and an oil outlet cavity are arranged on the two sides of the interior of the oil pump body correspondingly. According to the vertical-shaft-arranged oil pump structure, the driving gear and the driven gear of a gear pump are both of blade structures, axial force is generated along with rotation of the gears to balance the gravity of the driving gear and the driven gear, and reliable working of the vertical-shaft-arranged oil pump is ensured.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, and in particular relates to a structure of an oil pump arranged with a vertical axis. Background technique [0002] At present, due to the vertical arrangement of the crankshaft of the vertical axis engine, the axial direction of the oil pump is in the vertical direction, and the driving gear and the driven gear are affected by the gravity of the gears. The oil pump structure arranged in the horizontal direction cannot meet the reliability requirements of the oil pump. Contents of the invention [0003] In view of this, the present invention aims to propose a vertical shaft arrangement oil pump structure to provide a vertical shaft arrangement oil pump structure with simple structure, low cost, high reliability, and self-balancing gravity of the driving gear and the driven gear . [0004] In order to achieve the above object, the technical solution created by the present invention ...
