Abstract

Frictional characteristics of V-ribbed belt of aramid fiber reinforced rubber are significantly affected by form grinding conditions because of much lower coefficient of friction of aramid fiber and higher one of matrix rubber. In this paper, an in-process measuring system of coefficient of friction of V-ribbed belt in form grinding process is developed based on quantitative analysis of coefficient of friction in the previous report. Furthermore, a form grinding technique of V-ribbed belt for controlled coefficient of friction is proposed by investigating coefficient of friction in spark-out grinding process of V-ribbed belt. Main conclusions obtained in this paper are as follows; (1) The in-process measuring system of coefficient of friction of V-ribbed belt which can exactly predict its wide variation in form grinding process is developed. (2) In spark-out grinding process of V-ribbed belt, generation of V-groove is finished in a while from starting of spark-out grinding, and projecting length of aramid fiber continues to decrease gradually until the end of spark-out grinding process. (3) V-ribbed belt which has the required coefficient of friction can be finished by stopping grinding of V-ribbed belt when the measuring system points at the required coefficient of friction in spark-out grinding process after finishing to generate V-groove.
