Long-and-short-pitch chain transmission type multi-shaft rotating mechanism

Abstract

The invention discloses a long-and-short-pitch chain transmission type multi-shaft rotating mechanism. The mechanism comprises a pressure diffusion side plate, a gas inlet / outlet is formed in the middle of the pressure diffusion side plate, a multi-shaft rotating mechanism body is arranged on the periphery of the gas inlet / outlet on the pressure diffusion side plate, the multi-shaft rotating mechanism body comprises a plurality of long chain plates and a plurality of short chain plates, every two adjacent long chain plates are movably hinged through one short chain plate, and the plurality oflong chain plates and the plurality of short chain plates form a parallelogram crank connecting rod mechanism along the outer peripheral surface of the gas inlet / outlet; and each short chain plate isconnected with a rotating shaft, each rotating shaft is provided with a guide vane, each rotating shaft comprises one driving rotating shaft and other driven rotating shafts, and the driving rotatingshafts are connected with an external driving motor. The long-and-short-pitch chain transmission type multi-shaft rotating mechanism is reliable in transmission, good in stability and long in servicelife.

Description

technical field [0001] The invention belongs to the technical field of equipment manufacturing and processing, and in particular relates to a long and short pitch chain transmission type multi-axis rotating mechanism. 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 the airflow enters the power equipment. ...

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
