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.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
