Determining the Load on Support Rollers the Pipe Conveyor Belt

Abstract

The pipe conveyor belt design principles are considered in these pages. A method of calculation is suggested for the load on the base support rollers resulting from the bending of the initially plane belt into a cylindrical shell for the circular cross-section upon the elasticity theory with a non-uniform modulus, considering elongation and contraction variations in the elasticity modulus of the belt inserts which are positioned above and below the neutral surface at bending.

Increasing the wear resistance of highly loaded parts such as bodies of rotation by the method of vibration rolling

“…In friction of surfaces with conventional treatments (turning, grinding, polishing), sharp protrusions of microroughnesses can play the role of stress concentrators, while surfaces that are too smooth are prone to scoring and seizure, which can occur especially when lubrication is insufficient [19][20][21][22][23][24][25]34].…”

Belt Rotation in Pipe Conveyors: Failure Mode Analysis and Overlap Stability Assessment

“…Pipe belt rotation is a failure mode characterized by a variation in the belt overlap position in its longitudinal axis from the target position [28]. This may affect either the carry or return flights, for which the target is expected to maintain the overlap at the top and bottom positions.…”

Features of the manufacturing technology of a multilayer tool with an ordered texture

“…At the same time, the cross-sectional plane of the plate 3 has a transverse orientation with respect to the rolling direction. Thus, all the inserts have different deformation texture in their plane and in their cross-section, have different physical and mechanical, including damping, properties with respect to the action of the cutting force components loading the holder [1,[20][21][22][23]. Under the action of the cutting force, maximum tensile stresses occur mainly in the upper layers of the holder σt, and in the lower reference ones -compressive stresses σcomp.…”

“…Several fundamental studies [13,[20][21][22][23][24] have been devoted to the study of metal cutting auto-oscillations in order to understand the nature of chip formation processes in turning and to evaluate the importance of ensuring the stability of the technological system in machining. Due to the analysis and classification of methods and techniques for ensuring the dynamic stability of the technological system, it can be stated that, to a greater or lesser extent, all these methods allow for increasing the stability of the technological system.…”

“…The technological system is affected by an external periodic force that causes an oscillatory process with a frequency equal to the frequency of the perturbing force, or complex periodic processes due to the nonlinear properties of the system, as a consequence of which there are natural damped and forced oscillations, parametric excited oscillations, and auto-oscillations of the system. The intensity of forced oscillations is especially high under resonance modes conditions, which are inadmissible as operating modes in finishing machining on metal cutting machines [15,[21][22][23][24][25][26].…”
