Introduction
Instructions
The Lovejoy Deltaflex coupling requires no special tools or alignment equipment for installation. Use the
components shipped to align the coupling according to the instructions. See “Safety notice” below.
Before starting installation, check the squareness of the spacer tube and end plate assembly- See Figure 1 (a)on other side. Damage may occur in shipping and handling. If necessary, square up the plate with the tube
by tapping the plate lightly with a mallet or small hammer. If balancing is required, the coupling has beenmarked with registration marks to match up the components. If more than one spacer coupling assembly hasbeen ordered, don’t mix balanced component/matched sets. NOTE: As required, spacer flanges are assem-
bled to the spacer/floating shaft section and balanced as a subassembly. Usually the hubs have not beenbalanced as part of this subassembly - no match marks will be found on the hubs. (See Figure 2 on other side).
Step 1Assemble the two spacer flanges
to the hubs - See Figure 1 (b).Three cap screws and lock wash-ers are provided for each end.Torque the cap screws according
to Chart A for the hub cap screw
torque. Place the hub/spacerflange assembly on the equipment
shafts as shown in Figure 1 (c).LEAVE THE HUB SET SCREWSLOOSE AT THIS TIME.
Step 2Using the spacer dropout to deter-mine the position of the hubs:bring the hubs together or slidethem apart until the spacer
dropout fits snugly between theflange assemblies - See Figure 1(c). If the assembly has been bal-
anced, you will find register markson the spacer flange faces and thespacer-dropout plates (See Figure 2): Be sure to line up the regis-
tered holes, 1A-1A & 1B-1B, etc.
Step 3At this point, you will be able to
determine if you have correctalignment of the shafts. If thespacer mounting bolts do not fiteasily into the holes in the flanges,
alignment will have to be correct-
ed. You may flex the spacerflanges slightly in order to get
them to line up. If there is toomuch misalignment, the spacermounting bolts will not fit easilythrough the holes in the dropout
tube and the spacer flange assem-bly. Realign until the bolts go incomfortably. After realigning theequipment, Repeat Step 2 to be
sure that the spacer-dropout fitsbetween the spacer flanges with-out compressing or stretchingthe spacer flanges.IMPORTANT: To avoid axial com-pression or expansion of theflange assemblies, Follow Step 2 very carefully. The flexlinks in theflange assembly may be flexed
slightly due to angular misalign-
ment only. Tighten the spacerflange mounting bolts according to
Chart B. TIGHTEN THE HUB SETSCREWS LAST, per Chart C.
Step 4
When the equipment is turned onthere should not be any noise
emitting from the coupling if thealignment is correct. The couplingshould run quietly.
Safety Notice: It is very impor-tant that all rotation compo-nents be guarded to protect per-sonnel from inadvertent contactwith the coupling, belt drive,
chain drives etc. The guardshould also protect againstinjury from fragments of compo-nents in the event of part failure.Refer to safety standards suchas OSHA, state codes orMPTA/ANSI B15 for details.
