New Products: June 2017 Motion Design

Load Adaptor

Zero-Max (Plymouth, MN) introduced the Model 650 Overhung Load Adaptor that's designed to provide more radial and axial load support for hydraulic motors and pumps. The SAE B Model 650 is in the middle of the company's range of load adaptor sizes ranging from the smallest 200 SAE A mount model to the largest 1500 SAE F mount model. The new adaptor features a cast iron housing, 130,000 PSI stress-proof steel shaft, and heavy-duty spherical roller bearings. Designed for either face or foot mounting applications, it handles speeds up to 3500 RPM and is manufactured to ISO 9001:2008 quality standards. Overhung load adaptors protect the shaft seal of the motor, which can improve the operational life of the motor in harsh environment applications.

Sizing and Selecting Linear Motion Systems

The LOSTPED acronym can help designers avoid mistakes by reminding them to consider all the interrelated factors during system development and specification.

Virtually all manufacturing processes incorporate some type of linear motion. A common mistake that designers make when sizing and selecting linear motion systems is to overlook critical application requirements in the final system. This can lead to redesigns, and may also result in an over-engineered system that is costlier and less effective than desired. “LOSTPED” is a simple acronym that guides the designer in gathering the information needed to specify the appropriate linear motion components or modules in any given application.

Oil Sheer Clutch Cuts Downtime for Metal Stamping Press

Replacing a mechanical clutch, the oil sheer technology supplies constant, reliable tension on the stock feeding a 400-ton press to deliver precision and repeatability.

In the metal stamping business, precision, repeatability, and uptime are key. But stamping accuracy suffers when improper tension on the coil feeders incorrectly supplies metal to the presses, resulting in off-spec parts and increased rejections. ART Technologies of Fairfield, OH, relies on an oil shear clutch brake to supply constant, reliable tension on the coil feeding to one of its 400-ton presses to produce the precision and repeatability it needs, with no downtime for maintenance or adjustment. When the plant is working 20 hours a day, that uptime is as critical as the tolerances it maintains.

Piezo Technology in Pneumatic Valves

Solenoid devices are the standard for electrically controlled pneumatic valves. However, piezo valves offer many advantages over their solenoid counterparts, and open entirely new areas of application.

Pneumatic valves made with piezo technology offer many advantages. They are small, lightweight, extremely precise, durable, fast, and save energy. Piezo valves do not need energy to maintain a switching status, and therefore generate almost no heat. What's more, piezo valves can potentially be operated without any noise. Another key advantage is that they always work proportionally.

Adding Simple Vision Systems to Collaborative Robots

Upfront evaluation can help determine if a vision system is the best solution for an automation application.

Adding vision to a collaborative robot can open a world of possibilities for automation applications. With a vision system, a robot can inspect parts, check specific features of a part, recognize a part to pick it up, count items, adjust its path using visual feedback, color sort, and so on. The breadth of applications requires careful consideration to ensure selection of the right technology for the job.

Modular Climbing Robot Splits into Multiple Explorer Bots

Researchers from the Robotics Research Centre at the International Institute of Technology – Hyderabad (IIIT-H), have developed a stair and obstacle climbing robot that can disassemble itself into smaller robots, and then reassemble back into one device. As a composite system, the Detachable Compliant Modular Robot (DCMR) can climb steep obstacles and staircases, and explore uneven terrain. When it detaches into multiple robots, it can explore cramped spaces, traverse flat terrain, and behave as a Multi Agent System (MAS).

Actuated Smartwatch Moves in Five Directions

In an effort to make digital smartwatches more convenient for users, researchers at Dartmouth College and the University of Waterloo have produced a prototype watch face named Cito that moves in five different directions. With the ability to rotate, hinge, translate, rise, and orbit, the model improves functionality and addresses some of the limitations of today’s fixed-face watches.

Mechanical Actuators Bend as They “Breathe”

Extreme temperatures can severely strain a mechanical component because its material may have trouble enduring the heat without degrading. To address the problem, researchers at MIT developed a new material that expands and contracts as it lets oxygen in and out. The result is a new way to make actuators that could be used in extremely hot environments.

Technical Webinar Series from the Editors of TBMG: Integrating Motion Control for Safe Robot Operation

Manufacturing is changing. Robots and autonomous systems are used in more and more applications every day – many in safety-critical settings. No longer are robots kept in cages; they are working side-by-side with their human co-workers. Ensuring the safety of both robots and humans is vital and must be addressed early in the design stage. Designing robots for these safety-critical applications requires careful consideration of all aspects of the system, including proper motion control technologies that enable robots to maneuver in tight spaces originally designed for humans. Modifying standards for robot safety and human/robot interaction also must be a continuous process as these systems "learn."
