Produce rubber roller, 2018 - the cause of mechanical wave
11 -
18 a, bearing and pressure round the cause of the cylindricity out-of-tolerance: 1.
Single set of big difference, uneven pressure round, large difference of circumferential stress.
2.
Double circle pressure, stress release to outer.
3.
Double layer and aluminum plastic lining bearing residue in the hose between bearing iron shell.
Second, plastic bearings and acceptance check of the reasons: cause shaking big or lack of oil bearing clearance, bearing clearance after small that the lining rubber roller bearing aluminum bearing jammed, beating, rubber roller degumming of hole wall, aluminum lining rubber roller is not round, uneven surface hardness and other mechanical wave.
Three, the reason of the surface coating treatment: uneven rubber roller surface coating treatment or long sunlight, cause the rubber roller surface friction factor, rubber roller get in the car feel bad, produce mechanical wave.
Four, the reason of running: rubber roller winding deformation of fiber did not change in time, after serious winding fiber at the other end to continue or end.
