The testing of roller rotational resistance is essential in improving and searching for new design solutions to reduce the energy consumption of belt transport. The publication presents three methods of testing idler rotational resistance using various laboratory test stands designed and built by the authors. According to the first method, the test consists of applying torque to the roller axis and measuring the resistance force to rotate the roller axis. According to the second method, the test consisted of speeding up the idler, measuring the free stopping time and determining the moment of resistance to rotating the idler. The third stand enables the simulation of loads recommended by the PN-M-46606: 2010 and DIN 22112 standards, as well as operational loads, while measuring the dynamic rotational resistance. The comparative tests used two rollers different in terms of bearing type, hub type and quality of craft. The research object was ø133 × 465 rollers, most commonly used in the raw materials industry. The result of the research carried out is the assessment of the possibility of reducing the energy consumption of the belt conveyor by appropriate selection of the design features of a typical idler.

“…Permissible values of idler rolling resistance are specified in relevant standards, which recommend testing idler rolling resistance under a radial load of 250 N. However, the operating loads of the idler are much higher [11][12][13]. Therefore, standard requirements The testing of idlers with radial loads up to 8 kN have been presented in publications [5,10].…”

This publication presents the results of laboratory tests of idler rolling resistance under operational loads. Operational loads are understood as radial and axial forces acting on the idler, with values corresponding to those that occur in the conditions of its operation in copper ore mines. Knowing the rolling resistance is important not only at the stage of conveyor design, selection of the drive power or calculations of the necessary belt strength, but also when improving and searching for new idler design solutions. The idlers adopted for this research were differentiated in terms of bearings and idler axial clearance. The investigations were carried out on a unique test stand designed and built by the authors. The construction of the stand enables simulating operational loads while measuring the rolling resistance. The test rig measures idler bearing losses and rolling drag, not belt indentation rolling resistance. The object of the research were ø133×465 idlers, which are most commonly used in the raw materials industry. The results show the possibility of reducing the belt conveyor energy consumption by appropriate selection of the design features of the idler bearing unit.

“…The influence of dust particles on vibration characteristics, surface temperature, and bearing life is obtained (Radivoje et al, 2016). The book by Furmanik et al (2009) presented a way to diminish dynamic load and increase bearing life by adding a cushion between the bearing and the shaft. The authors concluded that the greater the belt stiffness, the smaller the viscosity and the damping; the smaller the dynamic load and bearing vibration, the longer the bearing life span will be based on a simplified oscillatory differential equation.…”

Idlers, one of the important parts of belt conveyors, are substantial and constitute approximately one-third of the equipment cost. Therefore, idlers in conveyor systems must be optimized. This study designs a new kind of idler on the basis of theoretical calculation and coupling simulation, with the shaft, shell, and labyrinth gland of the idler as optimization variables and overall cost and life span of the idler as objective functions. According to each independent variable of the idler, this idler adopts the equal strength beam concept and maximizes the overall carrying capacity of the shaft and the bearing by using a hollow step-shaft. The idler effectively adopts the one-piece casting labyrinth gland, thereby automatically enhancing the sealing effect with a screw structure in different rotation directions. The simulation analysis shows that under certain working conditions, the stress of the new idler shaft is one-third of the stress of the traditional idler shaft, and the strain is one-half of the traditional idler shaft, and the effect is obvious. A reliability analysis of the idler system is described in this work through the establishment of a fault tree, determination of the logical relationship of each component and provides methods for further research. Finally, the idler is verified to be practical in engineering applications, with a 10% cost reduction and considerable economic benefits.
