Weigh (Scale) Duty Idlers
(RECOMMENDED)
Idler misalignment amplifies the effect of belt tension and is the major
contributor of errors on Electro-Mechanical (E/M) belt weighing systems.
Idlers alignment can only be as good as the idler sets to be aligned.
Standard idlers vary from unit to unit in; troughing angle, T.I.R., idler
deflection etc.
This makes accurate alignment almost impossible. Poor roller balance can also
affect the scale performance.
To achieve the highest possible accuracy and most reliable operation one should
use Weigh (Scale) class idlers on: The Approach (before the weigh bridge)
The Retreat (after the weigh bridge) & The Weigh Bridge
Weigh (Scale) class idlers are designed to match the application and scale
model.
Each application is computer analyzed to optimize: Idler roll diameter, Roll shaft
diameter, Roll TIR, Roller dynamic balance, Idler base section, Deflections that
can be accommodated and Stiffness for very high speed applications.
These idler bases are manufactured to the stringent troughing angle tolerances
required for high precision weighing
duty.
