Embodiment Construction

[0055] The present invention will now be described in further detail in conjunction with the accompanying drawings and embodiments.

[0056] see figure 2 , 4 Schematic diagram of the structure of the present invention, the diagram shows that the modular internal gear pump or motor consists of a housing 16, an internal gear pair 20, an input shaft 18, a fixed bearing disc assembly 21, a floating bearing disc assembly 19, and a flange cover assembly 17 and the rear cover assembly 22, the flange cover assembly 17, the rear cover assembly 22 and the housing 16 are fixed in series by screws 23.

[0057] Please refer to Figure 5 , the housing 16 is a thick-walled cylindrical member with a substantially equal cross-section, and the center of the housing 16 is a cylindrical cavity 165 with both ends open. The lower part of the shell 16 cylinder wall (direction with figure 2 What is shown prevails, and the same below) is provided with an oil inlet 161 and two oil inlet passages 1...

Abstract

The invention discloses a modular internal gear pump or a modular motor, comprising a plurality of generalized components such as a shell, an internal gear pair, an input shaft, a fixed shaft tray component, a floating shaft tray component, a flange cover component, a rear cover component and the like, so as to form a barbell type combined structure connected in series, thus realizing modularization of functions, combination of structures and universalization of parts. The invention has the advantages of good universalization of parts, flexible and simple assembly and excellent adaptability of structures, thus achieving the beneficial effects of reducing inventory of parts, shortening the cycle of production and goods delivery and reducing operation cost of products.

Description

Technical field: [0001] The invention relates to a rotating liquid displacement machine, in particular to a modular internal meshing gear pump or motor for a hydraulic transmission system. Background technique: [0002] All hydraulic systems are inseparable from hydraulic components, and gear pumps or motors are one of the important hydraulic components. Compared with external gear pumps, internal gear pumps have the advantages of compact structure, light weight, small flow and pressure pulsation, low noise, and insensitivity to medium pollution, so they have developed rapidly in recent years. The basic structure of the internal gear pump is composed of a housing and an internal gear pair housed in the housing. The internal gear pair includes a rotor with teeth on the outer circumference (ie, an external gear) and a conjugated gear on the inner circumference. The ring gear of the gear teeth (that is, the inner ring gear), the ring gear is set in the housing and can rotate f...
