The split feature facilitates installing or removing the conveyer, while the adjustment permits an easy and accurate alignment.

Bending and Torsional Moments

Method of Calculating Moments for Shafts.

Figures 1 and 2 are given below as the most typical arrangements of wheels and bearings for which it is usually desired to figure exact shaft sizes.

Figure 1 covers cases of ordinary Belt, Rope, Chain and Gear Drives, also Single Strand Elevators and Conveyors.

Figure 2 covers cases of Double Strand Elevators and Conveyors in connection with Belt, Rope, Chain or Gear Drives.

Letter Values on Figures 1 and 2.

A, C, D, E, F, and G equal dimensions in inches.

H and H, equal respectively total driving or horse power pull* in lbs. on pitch radii E and G.

J and J equal respectively dead weight (including parts hanging on same) of Wheel 1 and Wheel or Wheels 2.

Use the larger shaft size obtained from Wheel 1 or 2.

Shaft Sizes From Moments.

The size of a shaft is determined from the largest pair of Bending and Torsional Moments to be obtained either from between the bearings of the shaft, or at the projecting ends beyond the bearings.

Use of the Tables.

After calculating and then selecting the largest pair of Bending and Torsional Moments by the methods as noted on preceding page, the shaft size is to be found at the intersection of those Moment values in the Tables.
