Embodiment approach

[0023] In order to show that according to the technical scheme of the present invention, a new product series of hydraulic parts that is obviously different from the prior art, including quantitative, variable hydraulic pumps, motors and hydraulic variable speed transmissions, is now enumerated as shown in the accompanying drawings. Seven examples are described. in:

[0024] There are three basic types of fixed displacement hydraulic pumps and motors. The first type: the rotor bearing adopts DU bearing, as shown in the attached drawing Figure 1 to Figure 19As shown, one end of the inner hole of the rotor main component 101 is provided with a transmission inner spline, and the inner part of the spline is equipped with a sealing plate 100, and the sliders 102 are fitted in the slider grooves on the outer circumference to form a rotor component, and the outer circumference of the component is eccentric Bearing sleeve 103, the front surface of two floating valve plates formed b...

Abstract

The rotary volumetric hydraulic mechanism includes block type hydraulic pump, motor and driver. The rotor block slot has profile curve of involute with pressure angle in the reference circle equal to 0 deg and geometrical parameters in modular system. Based on the specific application, the rotor bearing may be DU bearing or hydrostatic bearing. The present invention has the features of simple structure, easy manufacture, use and maintenance and low cost. The present invention has the adaptation range covering gear pump, blade pump, plunger pump and motor, and may form one new technology to develop serial products.

Description

1. Technical field: [0001] The invention relates to a rotary volumetric hydraulic device, in particular to a sliding member sequentially assembled in each groove evenly distributed on the outer periphery of the rotor. During the rotation process of the rotor, the sliding components are reciprocated and radially moved to form the volume change of the working chamber to complete the work. It includes a hydraulic pump, Hydraulic devices including hydraulic motors and hydraulic transmissions. 2. Background technology: [0002] The closest background technology with the present invention is: I propose the technical scheme in the invention patent application whose application number is 2004100715265, publication number is CN1587751A, and the title is "rotary volumetric hydraulic device and hydraulic transmission type oil extraction pumping unit". This background technical solution provides a rotor part and a stator part, which is composed of a rotor part and a stator part. The mat...
