11. Installation & Maintenance Instructions Eflex Coupling Hubs
1. The following instructions should be read and understood prior to
starting any assembly or maintenance work.
2. Prior to replacing any component, care should be taken to ensure
that it is clean and free from any dirt.
3. Bolts and screws should be tightened evenly, cylinder head
fashion, to 50% torque then to 100% torque in the same
sequence. Where specified it is essential that torque tightening
figures are not exceeded nor should it be allowed for them to be
below specification.
4. To ensure that where hub/shaft connections require a standard
interference fit the hubs may be heated in oil at 135° Celsius and
rapidly positioned on the shaft. It is essential that this heating
is evenly applied over the whole hub and that spot heating is
avoided.
5. Mounting Hubs
Coupling hubs are generally supplied with running or sliding
fits. Therefore axial restraint of the hub should be provided
by set screws when these fits are specified. Steel hubs are
recommended when interference fits are specified, making it
necessary to apply heat to the hubs, preferably in an oil bath or
oven to a max. temperature of 135° C. Mount each hub on their
respective shafts, normally with the face of each hub flush with
the end of its shaft and tighten set screws onto the key, when
supplied.
6. Alignment
Note: satisfactory alignment can be achieved with the use of
a straight edge and feeler gauge, although a dial indicator or
laser aligning equipment would generally improve accuracy,
independent of geometric component errors.
6.1
Gap and Angular Alignment
Set gap using a spacer bar equal in thickness to the nominal
gap specified in Table 1. With the spacer bar inserted to the
same depth, measure clearance between bar and hub face
at 90° intervals using feelers. Angular alignment should be
as close as possible, the difference between maximum and
minimum measurements should not exceed the angular
limits stated in Table 1.
6.2
Parallel Offset Alignment
Use a straight edge and feelers, or dial indicator over the
coupling outside diameter taking measurements at 90°
intervals. Align as close as possible, error must not exceed
offset limits specified in Table 1. Fit the coupling pins and
flexible elements ensuring that each capscrew has one
washer under its head and one washer on the other side
of the flexible element. Tighten all foundation bolts to
torques specified in Table 1, and repeat steps 6.1 and 6.2. if
necessary, re-align.
7. Maintenance Instructions
Periodically check alignment, check fasteners torques
and check flexible elements for wear to determine if
replacements are required. Excessive misalignment, high
ambient temperatures and / or frequent rapid reversing may
necessitate more frequent inspection.
