 LIGHTWEIGHT/STRONG
- Magnaloy is the original lightweight, heavy duty flexible drive coupling. Solid
magnesium alloy permanent mold castings are heat treated and offer the highest
strength-to-weight ration available. Light weight magnesium construction makes the
Magnaloy Coupling 76% lighter than iron and 36% lighter than aluminum units of similar
design. The benefits include reduced loads on bearings, shafts and pumps for longer
component life, easier handling and installation and rust proof and corrosion resistant
design.PRECISION MACHINED - The Magnaloy Coupling's wide, outside diameter
is machined to ±.001 inch and the bore is machined concentric to this diameter within
.002 inch T.I.R. These close machining tolerances assure vibration-free operation and
easy, accurate alignment without need for special tools.
SIMPLE
DESIGN - Magnaloy's Radial Lug Design is logical and efficient. The most common
failure of an elastomeric insert type drive coupling is hysterisis failure of the
elastometric element. Magnaloy Coupling's drive lugs are in a true radial orientation and
applied forces are evenly distributed in the compressive direction only, eliminating the
heat generating radial component. True compressive loading reduces internal heat
generation and improves elastomer life. Magnaloy's Load-Lock Design entails a negative
tapered configuration on the drive-lugs from top to base. Under load, the insert conforms
to the tapers, inter-locking the two hubs. This Load Lock design protects bearings and
equipment by eliminating end thrust in both directions.
FLEXIBILITY
- Magnaloy Couplings offer four-way flexibility (parallel, angular, axial and torsional)
and require no lubrication. They are easily installed and properly aligned without the use
of special tools or equipment. - a straight edge and hex wrench are the only tools
required. Magnaloy's insert reduces noise and vibration and permits needed flexibility for
proper operation within alignment capabilities.
EASY
ALIGNMENT - Magnaloy's wide, precision machined outside surfaces permit a simple,
but accurate alignment procedure. Simply place a straight edge at the top and side of the
coupling and adjust the equipment to permit no more than a .005 inch feeler gauge under
the straight edge. This will indicate accurate parallel and angular alignment. The maximum
recommended misalignment is 1° and the maximum recommended parallel misalignment is .015
inch. |
