Application of Cylinder Helix Torsional Spring to Gapless Linear Transmission System

Abstract

A new method of achieving steel band tension by using cylinder helix torsional spring was presented in the course of studying the gapless linear transmission system.The principle of the gapless linear transmission system was briefly described in this paper.The characteristics of the cylinder helix torsional spring were researched.The change of the steel band's tension and elastic deformation,as well as the encoder's output error was analyzed because of the cylinder helix torsional spring's inflection in periodic motion.A mathematical model was established and tested.The results indicated that the cylinder helix torsional spring could better achieve the function.It is concluded that the method can meet the design requirements。
