Pneumatics Provide Tight Position Control  by Andrew McCarty, Parker Hannifin CorporationSpinal cord injury (SCI) has potentially devastating consequences. As of June 2006, over 253,000 people in the U.S. had structural or functional issues related to spinal cord injuries. Evaluation of spinal implant devices requires testing systems that can replicate the complex motions and loads human joints commonly undergo. Continually improving equipment that can perform tests of strength, range-of-motion, and endurance contributes to breakthroughs in the treatment of SCI patients. The Datum Spinal Joint Endurance Testing Machine - recently designed and built by Datum Industrial Design, Inc., North Bergen, New Jersey - evaluates evaluates how spinal joints will function in human bodies. ...More >> The Best Balanced Planetary Ratio from a Torque Density Point of View By Dr. Gerhard G. Antony / Neugart USA LP  What ratio is the optimal for a certain application depends on the motor and application parameters such as required torque, rpm and, inertial match. For easier computation it is preferred that the planetary gearbox ratio is an exact integer ( 3, 4, 6 ..... ). Since we are so used to the decimal system, one frequently is tempted to use 10:1 even though this has no practical advantaged for the computer / servo / motion controller. Actually, as we will see, 10:1 or higher ratios are the weakest; using the least "balanced" size gears and hence has the lowest torque rating.

Sizing Pneumatic Cylinders and ISO valves By Chris Landis, Valve/Vacuum Product Manager, Parker Hannifin Corporation Look at flow coefficient, cylinder bore, and rod speed to best match pneumatic actuators and valves. In recent years, much discussion has centered on Cv ratings (also known as capacity coefficients or flow factors) and whether or not American, European, and Japanese pneumatic-valve manufacturers rate valves the same way. With ANSI/NFPA, ISO, and JIS organizations all specifying slightly different test methods and rating criteria, the confusion is understandable. ...More >> Are You Taking Full Advantage of Pneumatic Valve Technology? By Chris Landis Put advancements in pneumatic valves to work for your organization Pneumatic valves have come a long way since the development of the compressor over a century ago. Starting with large manual and mechanical valves, they migrated to individually wired electric solenoids and ultimately ended up with plug-into-the-base electronics allowing for a single multi-pin connector or fieldbus installation. Today's valves are smaller, faster and more advanced than their predecessors and offer many advantages that can be easily overlooked. With advancements in ISO valve standardization, collective wiring solutions and diagnostic capabilities, both end users and original equipment manufacturers (OEMs) are seeing significant cost reductions resulting from multi-vendor support, wiring simplification and decreased machine downtime. ...More >> The Low-Hanging Fruit in Pneumatic Systems  Compressed air has been used in industry and manufacturing processes for well over a hundred years. Virtually every plant has a compressor and uses compressed air in the manufacturing process. The supply of the raw material (the air in the atmosphere) is abundant, and compressed air is easily transported from the compressor to the point of use at the machine. It is easily understood by most people who use it and it is safe around most processes because air is generally considered to be benign in nature. It can be easily adjusted to vary the manufacturing process. So, it is easy to understand why its use in industrial manufacturing is so pervasive.

Selecting Keyless vs Keyed Connections for Motor to Gear Reducer  Knowing the differences between keyless and keyed-shafted connections is vital in distinguishing the advantages and disadvantages of both types of specifications when choosing a gearbox for your motor. In today’s marketplace, the need for speed, precision and small size are not only dictating the standard for shaft locking devices but also challenging motion component manufacturers to evaluate methods of keyless shaft locking for dynamic loads. Motor and drive manufacturers are making products in smaller and smaller packages which are increasingly capable of rapid acceleration and rotary positioning accuracy. These industry changes are causing backlash, stress distribution and balance to all be addressed in shaft locking devises, in many cases rending the shaft key obsolete...
