Low-noise long-life turning internal gear pump and manufacturing method thereof

Abstract

The invention relates to the technical field of gear transmission, in particular to an internal gear pump and a manufacturing method thereof. A low-noise long-life turning internal gear pump comprises a driving shaft, an oil inlet pump body, an intermediate pump body and an oil draining pump body, wherein an oil draining port in the oil draining pump body is formed in the right side surface of the oil draining pump body; an oil distributing disc is detachably arranged on the right side surface of the oil draining pump body; four oil outlet tanks are formed in the left side surface of the oil distributing disc; an oil outlet passage is further formed inside the oil distributing disc; the four oil outlet tanks are mutually communicated and then are communicated with the oil outlet passage; one of the four oil outlet tanks is communicated with the oil draining passage, and sealing rings are arranged on the other three oil outlet tanks. Due to adoption of the technical scheme, through additional arrangement of the oil distributing disc, an oil passage has the advantage: a simple unidirectional outlet becomes arbitrary outlets in four directions.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to an internal meshing gear pump and a manufacturing method thereof. Background technique [0002] The linear conjugate internal gear pump is one of the latest technical equipment of the hydraulic system equipment. It is widely used in the industrial field because of its significant advantages such as quietness, long life, and no trapped oil. [0003] refer to figure 1 , the existing internal gear pump generally includes a pump body with an inner hole, the pump body is connected by bolts from the oil inlet pump body 1, the middle pump body 5 and the oil discharge pump body 6, and also includes a drive shaft 15, a front cover 17, and an oil seal 18 , gear 10, ring gear 4, DU bearing 11, O-ring 20, and rear cover 21. When the gear pump is working, the hydraulic oil flows in from the oil inlet on the oil inlet pump body 1, enters the oil suction chamber, and is brought into...

AI Technical Summary

Problems solved by technology

Due to the constraints of the internal structure of the gear pump, the existing internal gear pump such as figure 1 As shown in , the oil inlet and outlet are on the same plane and cannot be turned

As a result, it has brought a lot of inconvenience in the actual configuration of the gear pump equipment pipeline manufacturing, and has brought restrictions on the installation, use and promotion of the internal meshing gear pump.
