Nook Industries have expanded
(Worm Gear Screw Jack) product line with linear actuation that requires less
electric consumption, fewer accessories and no hazardous materials. The
ActionJac line incorporates a rugged worm gear set arrangement that uses an
alloy steel worm, which drives a high strength bronze worm gear (drive sleeve).
The worm shaft is supported on anti-friction tapered roller bearings with
external seals to prevent loss of lubrication. The expanded ActionJac line is
comprised of standard machine screw, ball screw, stainless steel, metric and
trapezoidal screw jack options. Used individually or in multiple arrangements,
Worm Gear Screw Jacks are built to specification with customized travel lengths
and load handling capacities ranging from a quarter to 100 tons.
The ActionJac is for the solar
energy market and operates in extreme weather. Typical solar applications
include solar panels and machines that manufacture solar panel materials.
Examples include solar fields with fixed position panels, solar trackers that
align solar panels to the sun and collection towers.
Machine screw jacks: A lifting shaft made of alloy steel with a minimum
tensile strength of 95,000 psi. Machine Screw Jack lifting shafts are
manufactured with a lead accuracy of approximately 0.004 inch per ft.
Ball screw jacks: The ball screw and nut reduces the required input torque to
approximately 1/3 the torque required for Machine Screw Jack.
Stainless steel screw jacks: For use in demanding environments where corrosion
resistance is needed; external components are manufactured from 300 Series
stainless steel materials, including the worm. The stainless steel lifting
threads are precision formed to Class 2-C (centralizing) thread profiles.
Metric ball screw jacks: Metric model of ball screw technology.
Trapezoidal screw jacks: Metric jacks include a lift shaft with a special
trapezoidal thread form; created to stay within ISO standards and retains the
centralizing feature of 2C acme threads.
On Memorial Day, Americans remember the sacrifices the US armed forces have made, and continue to make, in service to the country. All of us should also consider the developments in technological capabilities and equipment over the years that contribute to the success of our military operations.
In order to keep in line with safety protocols, industrial networks need to be filtered in a semantic way so that only information related to diagnostics is flowing back to the vendor and that any communications that could be used for remote machine operations are suppressed.
Advanced visualization can depict an entire plant in motion, while also detailing an individual workstation. Individual products can be rendered different for each discipline involved — marketing, engineering, or suppliers.
