Two-wheel planetary fluid machinery, engine, fluid motor, compressor and pump

Abstract

The invention provides a double-wheel planetary rotating fluid machinery, an engine, a fluid motor, a compressor and a pump. The double-wheel planetary rotating fluid machinery comprises: a first rotation device and a second rotation device embedded with each other; each of the two rotation devices comprises: an annular piston space which is disposed around a main shaft and has an annular cross section perpendicular to the central axis of the main shaft; a plurality of roller planetary piston wheels which are uniformly disposed in the annular piston space and can roll along the annular piston space; a fluid inlet and a fluid outlet which are disposed face to face in directions perpendicular to the first main shaft and the second main shaft, and are respectively communicated with a superposed part of the two annular piston spaces; wherein the main shafts of the first rotation device and the second rotation device are parallel to each other; the two annular piston spaces are superposed partially; the plurality of roller planetary piston wheels of the first rotation device and the second rotation device are engaged with each other and pass through the superposed part of the two annular piston spaces. With a symmetrical structure, the fluid machinery of the invention can realize forward and reverse rotation.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to a fluid machinery device, an engine, a fluid motor, a compressor and a pump of a double-wheel planetary type. Background technique [0002] The applicant of the present invention filed a patent application for a planetary fluid motor or engine, a compressor and a pump on June 10, 2010 (patent application number: 201010196950.8). In the above-mentioned patent application, the applicant proposes a planetary rotating device. like Figure 1A and 1B As shown in the figure, the planetary rotation device includes: a cylinder body with a cylindrical cavity and a main shaft supported by the cylinder body sealing end covers on both sides of the cylinder body, and the central sun gear drum is sleeved on the main shaft; The outer cylindrical surface and the inner cylindrical surface of the cylinder form an annular piston space; the annular piston space can communicate with the flui...

AI Technical Summary

Problems solved by technology

[0004] (1) Due to the existence of the isolation mechanism, the star rotation device can only rotate in one direction, thus limiting some application scenarios that require two-way rotation of fluid machinery;

[0005] (2) The opening / closing noise of the isolation mechanism is large, so the star-rotary rotating device cannot be applied to scenes with strict restrictions on noise, such as household air conditioners;

[0006] (3) When the isolation mechanism is about to open / close, there is a certain gap in the output torque, so the planetary rotating device cannot be applied to occasions where the stability of the output torque is strictly limited;

[0007] (4) When the isolation mechanism is closed, it is subjected to a certain impact of the fluid, and a considerable amount of energy is lost on the impact, resulting in a reduction in the efficiency of the planetary rotating device
