MOTION CONTROL: The model AZ1040 drive from Amacoil Inc. is the most recent extension to the Amacoil-Uhing line of timing belt drives used for smooth linear motion in positioning and indexing applications. The drive features a one-piece aluminum profile extrusion which serves as the belt housing. T-slots and receiver grooves for the load carriage guide bars are incorporated into the profile design. The one-piece construction permits longer, sag-free stroke lengths without necessitating scaling up to a larger size drive. In cross-section, the profile reveals a dynamic crisscross structural pattern which further increases sag resistance and overall durability.
Belt pulleys are built-in to the AZ1040 end caps. T-slots are also designed into the end caps which provide more options for mounting and integration with other assembly components. The load carriage measures 188 mm x 160 mm (7.4 inches x 6.3 inches) and has pre-drilled and tapped payload mounting holes, and also T-slots running parallel to the line of travel. Maximum travel speed is up to 5.0 meters/second (16.4 ft/sec) depending on the weight of the payload which will also affect required drive torque and acceleration capability. The drive has a repeatability of +/- 0.2 mm (0.008 inches) over travel spans of up to 2,000 mm (6.5 ft).
Amacoil-Uhing AZ1040 timing belts are made of a heavy-duty synthetic rubber with a built-in steel cord strengthener. Multiple profile sections may be joined to accommodate long travel requirements. Five different AZ models are offered all of which are distributed in the USA by Amacoil, Inc.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
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.
