Improved low-backlash Slip-Ease clutches

SDP/SI offers a new, low-backlash variant of its existing line of multi-plate in-line slip clutches. Both versions feature an all-mechanical design, which makes them considerably cheaper than electromechanical alternatives. These clutches are commonly used for overload protection to prevent injury and machine failure, but have a wide variety of other applications such as tension control and positioning retention hinges like the ones in reclining chairs. The slip plates are layered with friction pads in between, and an adjusting nut sets the slip torque by squeezing the plates together. The outer plates are tabbed to fit into the output housing and the inner plates are connected to the input hub, so the two ends disengage from one another upon slipping.

Pre-Compensated Valve Platform for mobile machines

The Pre-Compensated Valve Platform from Bosch Rexroth makes it easier for mobile machine builders to selectively combine a range of hydraulic control valves into a single, integrated, multifunctional control solution -- with minimal need for adapter plates or custom fittings. All the valves in the platform support pre-compensated load-sensing capabilities that ensure the proper hydraulic flow is delivered to each function. The incorporated load-sensing capabilities improve efficiency, can help reduce hydraulic cooling system size and costs, and potentially lower engine horsepower requirements.

Modular and flexible multi-axis system from Festo

Festo offers a new, flexible mechanical system that consists of electric linear axes ELGC and the electric mini slide EGSC. The components can be used as individual axes or they can be combined quickly and easily to form multi-axis systems. The new system also meets the requirements for compact design and maximum modularity for a broad range of applications in electronics manufacturing and small part assembly such as manifold assembly, bonding processes, and pick-and-place applications.

Optics & thermal imaging -- precise motion required

From scanning buildings for heating and cooling inefficiencies to scanning crowds of people during the pandemic, thermal imaging systems play a critical role in many industries. Thermal cameras rely on many of the same motorized components as standard cameras, since they also require focusing, zooming, aperture adjustments, and quick-moving shutters. Inside these advanced optics systems, micro brush DC motors from FAULHABER make it possible for cameras to capture precise images and temperature readings in a fraction of a second.

What motor torque constant to use for drive type: Theory and application

Calculating motor torque from available drive current can be confusing due to many different drive types and the multiple ways current is specified. This informative online paper from Celera Motion provides the key formulas for torque constant and motor current from the fundamental principles of three-phase motor theory. It also walks through the many ways torque can be calculated. This information applies to a brushless motor (BLAC or permanent magnet synchronous machines) configuration.

Easy-integration compact Z-Theta motion platform

The easily integrated Z-Theta motion platform from Haydon Kerk Pittman offers linear and rotary point-to-point motion in a compact footprint. This modular, "bolt-in" package features the patented ScrewRail linear actuator, which combines guidance and linear transmission in a slender co-axial profile. The unique dual-motion integration with a pair of stepper motors adds rotary (theta) motion that reduces motion system size by 50% to 80% and provides as much as a 60% overall cost reduction when compared to traditional design approaches. This setup can be customized with a variety of lead screw resolutions, free-wheeling and anti-backlash nuts, stepper motor options, and optical encoder line counts.

Good beer. Zero packaging accidents.

The Danish division of Carlsberg, one of the leading brewery groups in the world, has significantly improved staff safety and taken steps toward achieving zero accidents since integrating Universal Robots cobots into its Fredericia-based factory. The company invested in two cobots, the space-friendly UR3 and the powerful UR10, to tackle carrying packaging cartons from the pallet to the magazine -- a monotonous and strenuous task that often left staff with repetitive strain or severe cuts. Working in tandem, the cobots can handle up to 500 packaging cartons per hour. Now the company has purchased four additional cobots to further automate its production lines.

Precise motion for optics and thermal imaging

From scanning buildings for heating and cooling "leaks," to scanning people at the airport for possible fever, thermal imaging systems play a critical role in many industries. Thermal cameras rely on many of the same motorized components as standard cameras: they require focusing, zooming, aperture adjustments, and quick-moving shutters. Inside these advanced optics systems, micro brush DC motors from FAULHABER help cameras capture precise images and temperature readings in a fraction of a second.

SureStep stepper motor linear actuators

Automation-Direct has added stepper motor linear actuators to its SureStep line of stepper motion control products. These linear actuators are NEMA 17 or 23 frame stepper motors with a stainless steel lead-screw extension of the rotor. In conjunction with the provided screw nut, these units translate motor torque into linear thrust. They can provide up to 193 lb of thrust, or speeds up to 18 in./sec. Eight standard leads (travel per rev) are offered, with screw lengths of 6, 9, or 12 in. They start at under 100 bucks.

U.S. Air Force Valkyrie 'loyal wingman' drone launches drone of its own in new test

The XQ-58A Valkyrie (large drone) demonstrates the separation of the ALTIUS-600 small UAS in a test at the U.S. Army Yuma Proving Ground test range in March 2021. This test was the first time the Valkyrie's weapons bay doors have been opened in flight. [Photo: USAF]

 

 

 

 

The U.S. Air Force Research Laboratory successfully completed the XQ-58A Valkyrie's sixth flight test and the first release from its internal weapons bay on March 26, 2021, at Yuma Proving Ground, AZ.

This test, conducted in partnership with Kratos UAS and Area-I, demonstrated the ability to launch an ALTIUS-600 small, unmanned aircraft system (SUAS) from the internal weapons bay of the XQ-58A. Kratos, Area-I, and AFRL designed and fabricated the SUAS carriage and developed software to enable release. After successful release of the SUAS, the XQ-58A completed additional test points to expand its demonstrated operating envelope.

"This is the sixth flight of the Valkyrie and the first time the payload bay doors have been opened in flight," said Alyson Turri, demonstration program manager. "In addition to this first SUAS separation demonstration, the XQ-58A flew higher and faster than previous flights."

At 30 ft long and with a wingspan of 27 ft, the unmanned XQ-58A Valkyrie is considered a stealth "loyal wingman" drone that flies as an escort with jet fighters such as the F-22 or F-35 during combat missions. It is controlled by its parent aircraft and has a maximum speed of 650 mph using its turbofan engine. Max range is 3,000 nm. It has two weapons bays (that can contain multiple bombs or, now, at least one drone) and a total capacity up to 600 lb. It has a dry weight of 2,500 lb.

The 3-ft-long ALTIUS-600 has spring-loaded wings and supports a Multi-Domain Operations (MDO) system so it can be launched from the air, sea, or ground from systems like the Common Launch Tube (CLT), Pneumatically Integrated Launch System (PILS), and other launch systems. It was designed with a modular payload nose that can hold up to 6 lb (sensor or weapon) and has a range of 276 miles.
