New Light- And Heavy-Duty Knitted Mesh Vibration Mounts From AAC Are Designed For Corrosive Environments
Two
new series of base-mounted stainless steel knitted mesh vibration
mounts introduced by Advanced Antivibration Components are designed
for marine, aerospace and machine shop applications where corrosive
environments could cause conventional isolation materials to fail or
operate at reduced efficiency. The stainless steel springs and
resilient knitted pads are unaffected by oil, water, ozone,
bacteria, corrosion, or temperature extremes (no efficiency change
occurs between -94°F and +347°F (-70°C to +175°C)).
The light-duty mounts, identified
as the V10Z22 Series, are designed for marine, aircraft and other
mobile applications and conform to MIL-E-5400C military
specification. The series consists of many different mounts ranging
in static load capacities, from 1.55 to 132.30 lbs. (0.7 to 60 kg),
and mounting configurations 1/4-20 to 3/8-24. The units are
constructed of stainless steel springs and resilient mesh pads which
are enclosed in an aluminum alloy housing. The dynamic
characteristics include a ratio between transverse and axial
(vertical) stiffness of approximately 1:2.5. Their natural frequency
is equal to 7 to 10 Hz vertical and 4.5 to 6 Hz transverse,
depending on load, for a displacement input of
±.030" (0.75 mm).
Transmissibility is less than or equal to 4:1. The units have a free
height of 1-27/32" (46.3 mm) with a base dimension of
2-3/8" sq (60.5 mm sq). Unit weights range from 3.53 to 4.41 oz
(100-125 g).
The heavy-duty mounts, identified
as the V10Z28 Series, are designed for machine tools, motors,
generator sets, printing presses, textile machinery and pumps. This
series consists of 6 different mounts ranging in static load
capacities from 10 to 1000 lbs. (4.55 to 453.5 kg). The natural
frequency of the units are 13-17 Hz for an amplitude of ±.012"
(±0.3 mm). The resilient material used is knitted stainless steel
mesh. Aluminum alloy coated with Alochrome 1200 is used for the
housings. Unit free height is 1.91" (48.6 mm), with a maximum
compressed height of 1.44" (36.6 mm.). Base dimensions are
3" sq (76.2 mm sq). Unit weight is 6.33 oz (180 g). |
