Abstract

This paper represents part II of a two-part effort which focused on the development of an experimentally verifiable mathematical model of a lever-type roll feed mechanism. The theory developed in part I is applied to the actual mechanism and the computed results are compared to the experimental ones. Reduced equations could be introduced for all four regimes since both numerical computations and experiments showed that consideration of the out-of-plane deflections could be excluded. In the experimental set-up, the motion of the mechanism is monitored by three angular encoders, which are attached to the drive shaft, the rocker-link shaft, and the feed roller shaft, respectively. Their output, which is stored in a specially designed data acquisition system, allows the correlation of the instanteneous rotations of the feed roller and the rocker shafts to that of the drive shaft. Strain gages provide in and out-of-plane bending-strain histories of the bent coupler. Experiment and theory, for different loading conditions, are correlated by way of the coupler strain, the clutch windup angle and the total feed length. Good qualitative and quantitative agreement between computed and experimental results was found.
