固定压轴力的带传动,其中心距随载荷的变动而变动。固定中心距的带传动,其压轴力随载荷的变动而变动。为查明其变动规律,我们在直流电封闭带传动实验台上设置了“中心距与压轴力综合调解装置”,并对小型号的V带做了这方面的实验。本文介绍该“调解装置”的结构、原理、实验方法及实验结果分析。 Fixed axial compression belt drive, the center distance varies with the load changes. Fixed center distance belt drive, the axial force changes with the load changes. In order to find out the regularity of its variation, we set up the “center mediation and axial force comprehensive mediation device” on the DC closed belt transmission experiment platform, and did experiments in this respect for small V-belts. This article describes the “mediation device” structure, principles, experimental methods and experimental results.
