Features :
1.) Impellers are
machined from cast iron to an exact profile and are permanently
fastened to steel shafts. They are dynamically balanced for smooth
operation in any installed position. This feature provides extra
strength and rigidity to handle continuous maximum loads without
fatigue or deflection.
2.) Head plates,
machined from cast iron, are ground on the interior surface to
precise operating tolerances. Bearing fits are machined into head
plates to assure exact bearing positioning. This feature provides
accurate, fixed-dimension clearances through all blower operating
temperature ranges.
3.) Impeller case,
machined from cast iron, are heavily ribbed to prevent distortion
and reduce noise transfer. Inlet and discharge ports are integral
features of the cylinder. Oversized dowel pins maintain proper
internal alignment, assure quieter, trouble-free operation.
4.) Anti-friction bearings are used exclusively. Smaller sizes are
fitted with single-row ball bearings and cylindrical roller
bearings, while larger sizes have double-row ball bearings and
spherical roller bearings. This optimum bearing selection provides
longer blower life and added overhung load capacity.
5.) Timing gears, precision machined from alloy steel forgings, are
permanently pinned to shafts. This feature assures non-slip timing
even under the most strenuous loading conditions.
6.) Timing gears and gear end bearings are lubricated utilizing an
abundant oil reservoir. A graphite, oil-tight housing encloses the
timing gears. The drive end bearings are grease lubricated through
external fittings. Lip-type seals prevent oil and grease from
entering the impeller chamber. This feature provides superior gear
and bearing lubrication at all operating conditions with minimal
maintenance.
7.) The Legend's flex-mount design allows for either vertical or
horizontal installation. The feet are precisely machined and match
the footprints of many competitive units. Drive shaft is extended
for v-belt drive or direct connection. Allows adaptability and ease
of installation of Legend blowers to all blower applications. |
