This configuration lessens wear, increases load capacity, and improves efficiency. The threaded chain consists of nut-shaped links. This paper presents the results of tests carried out on a prototype with a reduction ratio of 46. %K Speed Reducer %K Inverted Roller Screw %K Chain Drive %K Threaded Chain Drive %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=130224
