Noisy Bearings? Single-turn wave springs are ideal for bearing preload. The spring preloads the bearing through its outer race, taking up play in the bearing. This reduces bearing damage, wear, noise and vibration. Smalley has stock parts from 1/4" to 16". Specials are available from .200" to 120".

The latest in silicone/thermoplastic parts molding |
|
 The practice of bonding Liquid Silicone Rubber (LSR) to rigid thermoplastic parts has traditionally consisted of molding the individual elements separately and then assembling them into a completed product using adhesives. Today, companies like Rogan Corporation have taken that process one huge step further -- by molding Bondable Liquid Silicone Rubbers (BLSR) and thermoplastics using a two-step molding process. This article includes 6 Critical Design Considerations for BLSR/thermoplastic molding.

The science of spin: flywheels High-speed flywheels are a cheap and efficient way to hybridize systems from cars, elevators, and industrial machinery to inter-city trains. Yet until now their development has been hindered by the lack of a robust way to transmit the power to and from them. Jesse Crosse reports on some ingenious new developments at Ricardo.

Wheels: Cyclists take industrial 3D printing for a spin About four years ago, Russell Kappius -- mountain-bike enthusiast, winner of six Masters racing titles, and a research geophysicist/software developer -- became obsessed with bicycle hubs. After working out a design for a novel oversized hub and high-performance drive assembly that would transfer more power from pedal to chain to wheel, he looked to direct metal laser sintering (DMLS), an additive manufacturing (3D printing) technology, to produce complex parts quickly to exacting specifications.

Extreme miniaturization: 7 devices in one chip navigate without GPS The U.S. military relies on the space-based Global Positioning System (GPS) to aid air, land, and sea navigation. Like the GPS units in many automobiles today, a simple receiver and some processing power is all that is needed for accurate navigation. But what if the GPS satellites suddenly became unavailable due to malfunction, enemy action, or simple interference, such as driving into a tunnel?

Motors for model train meet demanding requirements Building an N-gauge (1:160) model train system involves working with very small units. The 1930s-inspired BR 70 locomotive from Fleischmann is only 2.25 in. long when measured buffer to buffer. As on large locomotives, traction (and on the model, power transmission) between the wheel and the track is a crucial factor. To give the unit appropriately scaled big-train power with low vibration and noise, the folks at Fleischmann turned to customized DC motors from the FAULHABER Group.

| Is PETMAN a warfighting droid in training? | |
| Boston Dynamics, famous for its BigDog four-legged military pack-animal bot that can carry hundreds of pounds, developed the PETMAN robot for the DoD to test the performance of protective clothing designed for hazardous environments. But doesn't it look capable of so much more? PETMAN has sensors embedded in its skin that detect any chemicals leaking through the suit. The skin also maintains a micro-climate inside the clothing by sweating and regulating temperature.
