Radially-distributed multi-shaft rotating mechanism based on symmetrical double-crank assemblies and spatial connecting rods

Abstract

The invention discloses a radially-distributed multi-shaft rotating mechanism based on symmetrical double cranks and spatial connecting rods. The mechanism comprises a guide vane assembly and a transmission mechanism; the transmission mechanism comprises a plurality of spatial connecting rods and double-crank assemblies; two adjacent spatial connecting rods are movably hinged to each other throughthe double-crank assembly; the plurality of spatial connecting rods and double-crank assemblies are distributed along the outer circumferential surface of a mounting flange so as to form a connectingrod movement assembly; the middle positions of each of the double-crank assemblies are connected with rotating shaft respectively; the rotating shafts comprise one driving rotating shaft, and the other rotating shafts are driven rotating shafts, wherein the driving rotating shaft is connected with an external driving motor; and the guide vane assembly is connected with any one of the spatial connecting rods. The radially-distributed multi-shaft rotating mechanism based on the symmetrical double cranks and spatial connecting rods of the invention has the advantages of high transmission efficiency, low manufacturing cost, high standardization degree, high performance safety and reliability, and long service life.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing and processing, and in particular relates to a radially distributed multi-axis rotating mechanism with symmetrical double crank space connecting rods. Background technique [0002] At present, centrifugal fans, compressors, pumps and other power equipment are often used in metallurgy, petrochemical, natural gas transmission, refrigeration and power industries. There are currently two ways to adjust the gas flow in the process, namely inlet adjustment and outlet adjustment. [0003] The function of inlet adjustment is to adjust the flow into the rotor of the power equipment through inlet throttling. The traditional process uses butterfly valves to adjust the inlet flow of the power equipment. This method causes a large loss of gas when it enters, resulting in greater energy consumption. The adjustable inlet guide vane will produce a certain airflow pre-swirl angle when t...

AI Technical Summary

Problems solved by technology

Since the gas medium in contact with the adjustable outlet guide vane has been compressed by the fan or compressor and has a very high temperature, the research and development of the adjustable outlet guide vane has always been a difficult problem in China. There are many types of export guide vane transmission structures abroad. , but lack of stability and reliability
