Scientists about friction and the level of inplementation of the results

The article presents the main indicators of friction drives of belt conveyors: traction coefficient, operating parameters of contact surfaces, drive service life, etc. Troubles of design, improvement of manufacturing and production, which are objective with by many design, production and operating companies in many countries. According to the currently available data analysis, the need to increase the thraction factor (maximum = 40) and performance capabilities have not yet been exhausted, especially since the friction coefficient in vacuum is high and at the same time stable to rheological conditions; Based on this, the possibility of obtaining a high thraction factor ( ) using a vacuum drive independent of rheological conditions is being investigated.
