Introducing the Smallest Wave Springs on the Market
Smalley has expanded the Crest-to-Crest® Wave Spring Series. Smalley's popular C (imperial) and CM (metric) Series have been expanded; standard sizes are now available from stock down to .188 in. and 5 mm in diameter. Smalley Wave Springs can replace conventional coil springs while occupying only half the space and providing the same force and deflection.

New Piezo Motor with Integrated Optical Encoder
MICROMO launches the new Piezo LEGS® Linear 6N motor, also called the Piezo LL06. This new motor is the next generation of the classic Piezo LEGS® LL10 with the same piezo ceramic actuators at its core as the popular predecessor, LL10 with some major redesign work. The LL06 features an integrated high-resolution optical encoder, plus a slimmer design and options for guides that steer the drive rod.

Army engineers advancing component miniaturization

Engineers at the U.S. Army Armament Research, Development and Engineering Center have been making advancements in an initiative called "component miniaturization." The mission is to make armament systems more precise, energy efficient, scalable, and effective by reducing the size of critical components in sub-systems such as safe and arm devices, electronics packages, power supplies, and inertial measurement systems.

SUHNER gives primer on spiral bevel gears
Each year, engine and motor power increases require more powerful angle gear heads. Engineering developments in mechanical engineering, the tool-making industry, and industrial hand tools call for higher rotating speeds while smooth and easy movement of the tool is maintained. Smoother-running gears are also needed to combat dynamic noise. Apart from bearing and housing stiffness, the overall design and gear dimensions are essential for gear system optimization.

Software created to design your own custom drone
Designing less conventional drones requires expertise in multiple disciplines, including control systems, fabrication, and electronics. A new system from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) makes the process much easier, allowing users to design, simulate, and build their own custom drone based on the specific needs they have for payload, cost, flight time, battery usage, and other factors.

Aluminum treads on Mars Curiosity rover show open breaks and tears

A routine check of the aluminum wheels on NASA’s Curiosity Mars rover has found two small breaks on the rover’s left middle wheel -- the latest sign of wear and tear as the rover continues its journey, now approaching the 10-mile mark. NASA lays out the problem, and Designfax delves a little deeper into the cause.

What they don’t teach you about polymer gears in engineering school
Gears, especially in open gearing applications, share a set of well-known performance problems that crop up again and again across many different applications. The most common ones include excessive noise, vibration, heat, weight and corrosion. Gears also tend to be either over-lubricated or subject to wear, which respectively causes contamination from grease or metal particles. At best, all these performance issues will result in gears that are expensive to maintain. At worst, they will cause gears to fail prematurely, driving costs even higher.
Download the Intech Corp. paper to read how you can solve all of these problems with good polymer gear design practices.

Metal tape measure technology grows up

When first-timers see the Zippermast rise into the air from an unmanned vehicle, they are amazed by how high it can be extended. Inspired by the lowly metal tape measure design, the compact and super-sturdy Zippermast consists of three interlocked steel tapes that also function like a locking zipper, lifting cameras and sensor equipment up to 40 ft in the air. A small DC motor from FAULHABER provides the unique design with reliable retraction and extension, all incorporated into an amazingly small base housing.

Mike Likes: Superbolt VersaTite: A revolution in tensioning
The new VersaTite Hydraulic Mechanical Tensioner from Superbolt combines the speed and uniformity of hydraulic tensioners with the accuracy of Superbolt mechanical tensioners. VersaTite products can be hydraulically pressurized to achieve a fast and uniform initial preload, and the achieved preload is easily controlled by mechanically applying the final torque using Superbolt multi-jackbolt tensioning. Either mechanical or hydraulic removal is possible. Application examples include gasketed flanges requiring simultaneous loading of the bolts to evenly load the gasket and any joints requiring high residual bolt loads (turbine casings, tie rods for generator and turbine rotors, slew rings). Product examples include heat exchangers, catalyst crackers, petrochemical reactors, valves, and pumps.

Top 12 priority clutch/brake application criteria for medical OEMs
Incorporating the right clutch or brake early in the design process saves time, reduces costs, and ensures proper performance -- and every clutch/brake design project has several factors in common. The experts at SEPAC have outlined the 12 most important criteria to consider when selecting a clutch or brake for Medical Equipment Manufacturers. The paper covers issues including heat generation/dissipation, response time, alignment, torque, and voltage/current objectives. SEPAC is a custom engineering company and manufacturer of motion control products, including electromagnetic clutches and brakes.

Wings: Boeing's factory of the future: 777 automated assembly
Take a peek behind the scenes of Boeing's factory of the future. Fuselage Automated Upright Build (FAUB) is a partnership of automation and manual work to assemble the forward and aft sections of the 777 fuselage. Teams load and set the panels, then the robots are moved in to help install thousands of fasteners to connect the sections. Mechanics are able to move the robots and massive parts around on automated guided vehicles (AGVs).

Infrared LED optimizes license plate recognition and more
Osram Opto Semiconductors is expanding its family of high-power infrared Oslon LEDs for illumination solutions to include a new wavelength, 810 nm. The new SFH 4703AS infrared emitter will improve the performance of inspection and scanning camera systems, such as those used to read license plates. The additional wavelength enhances image contrast, making it easier to read patterns from recorded images at any time of day. At 1 amp current, the emitter generates 1 W of optical power. With this new device, designers can now choose from mutually compatible emitters in three different wavelengths.
