NOTE!
Adjust the wheel stands so that the axis of rotation of the vessel is on the centre line of the
drive and idler frames.
4.4 Adjusting the included angle
The included angle (α) is the angle between two lines from the centre of the rotation axis of the vessel
to the centre of each wheel on the drive or idler section. As the angle increases, so do the resulting
load on each wheel, and consequently, the load on the bearings. Also, by increasing the angle, more
torque, therefore more power is required to rotate the vessel.
The distance between the wheel stands, on both the drive unit and the idler units depends on the
diameter of the vessel. To achieve a safe and smooth operation of the roller beds the recommendation
is the keep the included angle (α) between 45° and 70°.
