Abstract

The article provides a discussion on the results of the original studies of a power transmission system of a mining scraper conveyor coupled with an innovative highly flexible clutch, conducted in operating conditions. The research consisted in establishing the static characteristics of the highly flexible clutch in question, determining the torsional vibrations of the said highly flexible clutch and the vibrations of the transmission housings at a test rig, verifying if the coupling between the innovative flexible clutch and a typical scraper conveyor drive unit was correct, and testing durability of individual components of the highly flexible clutch. Following the aforementioned tests, one can distinguish three phases of its operation: initial, main, and final – all differing in terms of flexibility. Furthermore, upon increasing the flexibility of the metal clutch, a significant decline in the root mean square (RMS) values of linear vibration accelerations was observed compared to the blocked condition of the clutch.

通过使用创新型高弹性金属联轴器，减少采矿刮板输送机驱动系统的动态负载

文章讨论了在运行条件下对矿用刮板输送机的动力传输系统与创新的高弹性离合器进行耦合的原始研究结果。研究内容包括确定相关高弹性离合器的静态特性，确定所述高弹性离合器的扭转振动以及试验台架上传动箱的振动，验证创新型高弹性离合器与典型刮板输送机驱动装置之间的耦合是否正确，以及测试高弹性离合器各个部件的耐用性。经过上述测试，我们可以将离合器的运行分为三个阶段：初始阶段、主要阶段和最终阶段，所有阶段的柔性都有所不同。此外，在提高金属离合器的柔韧性后，与离合器的阻塞状态相比，线性振动加速度的均方根值明显下降。
