Cycloid gear pump industry applications extended

Because nothing like cycloid gear involute gears meshing in the center distance separability , tooth profile curve equation is complex and engaging ordinary cycloid gear pump is a multi- point contact . Gang Here, cycloid gear machining high precision , small processing errors might prevent the assembly, or uneven loads .security tie Prior to the 1980s of last century by means of design calculations and processing technical limitations , cycloid gear pump application subject to certain restrictions. With the increased level of processing technology , especially the development of numerical control technology , cycloid gear machining accuracy gradually improved , the cost becomes lower , cycloid pump renewed attention .

Its application range with gradually expanded from general industrial extended to the field of micro-mechanical hydraulic systems and bio- engineering . With more teeth difference cycloid gear pump and the emergence of modern design and manufacturing technology development , research and cycloid gear pump by domestic and foreign scholars and producers attention. Recently, there are many foreign companies producing such a gear pump . It is understood that a large number of imports from abroad, air compressors, chillers, oxygen compressors, expanders , and a large number of chemical raw material conveyors often appear on the cycloid gear pump , especially in the chemical industry for delivering high-viscosity liquids on the device .trailer seals China also has many companies began producing teeth difference cycloid pump , but all in imitation of similar products abroad , mainly in order to meet the need for equipment maintenance .
