On a New Measuring Method of Belt Tension and the Application

Study on the Belt Grinding (1st Report)

Abstract

In this paper, the new method is investigated to measure the tension acting upon the belt by means of detecting the electric signals from a strain gauge pasted on the inside of belt. As the strain gauge comes into contact with contact wheel, the information transmitted from the strain gauge gives possibility to analyze many grinding phenomena such as over cut, grinding performance, etc. The values of belt tension (Pδ), which are measured with this method, are used for calculation of over cut as an example and the results of this calculation are compared with the experimental values.
The main results are as follows.
(1) The smaller the initial tension is, the larger the over cut becomes in the grinding condition of same rubber hardness. In the case of same initial tension, the over cut increases as the rubber hardness decreases.
(2) The over cut increases with the increasing of contact wheel velocity. Moreover, using the variety of belt tension (Pδ), it may be possible to analyze the grinding abilities for the serrated contact wheels.
