  • Advantages and disadvantages of harmonic gear reducer and its application

    introduction:Due to the structure and working principle of harmonic gear reducer and ordinary gear reducer friends are very different,It is decided that its application is different,The following lists the advantages and disadvantages of harmonic gear reducer and its application fields。 Major advantage (1)High transmission speed ratio。Single-stage harmonic gear transmission speed ratio range is70~320,It can be achieved in some devices1000,Multistage transmission speed ratio can be reached30000above。Its not just for slowing down,Can also be used for the occasion of growth。 (2)High carrying capacity。This is because the number of teeth engaged at the same time in harmonic gear transmission is large,Double-wave gearing
