Mechanical Static/Dynamic Photoreceptor Module Belt Tension Measuring

This disclosure describes a measurement technique utilizes analytical modeling to evaluate the tension in a belt.

This concept of measuring belt tension would include penetrating the normal, freely supported belt region by a fixed displacement and measuring the resulting reactions to calculate the static and/or dynamic tension in a belt at a particular location.

Applying a displacement to a tensioned belt will require a force proportional to that displacement.

This relationship to tension is shown by:

This concept of measuring belt tension would include utilizing a solid shaft that is free to rotate along its axis.  This shaft is then mounted in housings at each end that contain either a load cell or strain measurement device to look at the reactions at each end of the roll due to the normal force applied by the belt. 

Data is then sampled in either a static or dynamic belt condition to monitor the output of the load measurement device.  Through analyzing the output using basic calibration and analytical calculations, a belt tension measurement can be approximated.  The reactions will also define tension variation in the reactions along the belt width.
