BASICS OF XenoROL INSTALLATION
GENERAL
XenoROL® bed sections stacked on pallets for shipping
(7) intermediate beds per side.
Straight bed sections may be installed using any of
the support methods previously described (see
SUPPORTING ARRANGEMENTS). As each bed is
installed in the system, level it lengthwise and
across the bed width on a roller. The supports
should also be checked for vertical. A shorter level
may be required to check the upright without the
level overlapping the lower boot.
If it becomes necessary to shorten a bed frame, cut
the end bed where a coupler is not needed, if
possible. If the drive must be continued, it is best to
disassemble the line-shaft assembly and re-keyway
the line-shaft's cut end. If only a small amount of
conveyor is driven by the cut bed, the coupler
sprocket may be field welded or pinned to the cut
end of the shaft.
When joining bed frames it is important to align the
rollers and line-shaft. Care must be taken to make
sure the rollers are level (carrying surfaces) from
bed to bed.
All bed frames should be checked for squareness.
To check, measure diagonally from corner to corner.
Measure the opposite corners in the same manner.
If the bed is square, the two measurements will be
the same within 1/16".
FRAME ALIGNMENT
Conveyor frames must always be installed in a
straight line from end to end as described in
GENERAL PROCEDURES. After a number of
sections have been installed to the chalk line and
leveled, check the alignment of each line-shaft
assembly. As the conveyor sections are bolted
together, the coupler sprockets may require
adjusting. The edge of the 1" diameter line-shaft
must be 2" from the frame channel to start.
COUPLER ALIGNMENT
Check the alignment of each pair of coupler
sprockets. Parallel alignment can be checked with a
straight edge placed on the two sprockets at the root
of the teeth. Alignment should be checked in at
least two places, at 90 degree intervals. The
straight edge must appear level to the coupler hubs
or line-shaft. This will put parallel alignment within
the specified .005" limit.
If the coupler sprockets do not align vertically, adjust
either or both of the following:
1. Loosen the crossmember mounting bolts of two
crossmembers in each bed and adjust the height
of the crossmember within the limits of the
mounting holes.
2. Insert shims between the bearing housing and
the bearing hanger of the crossmember.
Tip : Loosen one coupler sprocket and slide it
against the other. Adjust the line-shaft for zero gap
between sprocket faces and exact mating of teeth.
Then move loose sprocket back 9/32" and tighten
set screws to 13 ft.lbs.
