  • The paper discusses studies of a power transmission system featuring a torsionally flexible metal clutch of innovative design, transferring a high torque, which is considered a novelty given the current state of technology.
  • The experiments conducted under the studies revealed that the gear transmission vibrations had been successfully reduced, which should be attributed to the resulting reduction of the dynamic forces triggered by external factors.
  • Following tests conducted in operating conditions, the highly flexible clutches of innovative design were found to be suitable for mining conveyors operating under high loads.
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.
This research was developed under project POIR.04.01.04 00 0081/17 entitled “Develop innovative scraper conveyors with increased start up flexibility and service life”, co financed by the National Centre for Research and Development in Poland.
