Wire Springs versus Machined Springs: A Comparison

The first question generally asked about Machined Springs is how they compare with Wire Wound Springs. Commencing with this question, this review of Machined Springs will proceed. Wire Springs appeared early in the Industrial Revolution. They established their value immediately, and have not wavered from that most useful course. Certainly, enhancements in materials and manufacturing have been forthcoming, but the basic concept has not changed much. Spring wire coiled hot or cold with ends configured within the limits of coil wire has proven to be a very cost effective, industrial tool that exhibits elasticity within the bounds of known, engineering understanding. Uses range from deep ocean applications to man's reach into the universe. Finding a modern day device large or small, that does not benefit from elasticity, and particularly that provided by Wire Wound Springs, is a rare find.

Piezo Engineering Tutorial

1.0 The Direct and Inverse Piezoelectric Effect In 1880, while performing experiments with tourmaline, quartz, topaz, cane sugar and Rochelle salt crystals, Pierre and Jacques Curie discovered that when mechanical stress was applied to a crystal, faint electric charges developed on the surface of that crystal. The prefix “piezo” comes from the Greek piezein, which means to squeeze or press. As a result, piezoelectricity is electrical charge that is produced on certain materials when that material is subjected to an applied mechanical stress or pressure. This is known as the direct piezoelectric effect.

VINCENT Systems Prosthetics Give Patients A New Feel For Life

The human hand is a biomechanical marvel, but our hands are easy to take for granted because we depend on them all day long. People without all or part of their hands, however, know full well the value of what is missing as they struggle to perform even simple, everyday tasks.

Why bigger isn’t always better: the case for thin section bearings

For applications that demand maximum performance despite space and/or weight restrictions, designers should consider thin section bearings. While conventional bearings often have more load capacity, thin section bearings have more than enough for a wide range of applications and offer exceptional design flexibility with opportunities for significant reductions in overall system size and cost. A new white paper from Kaydon Bearings, an SKF Group company, examines thin section bearing styles and features, with a discussion of design considerations, fit, lubrication, and other useful information.

The Stealth E-Bike: Challenges in Developing the First Fully Integrated Drive System for E-Bikes

The idea of a bike with pedal assistance is very old, dating back to 1860, when pedal assistance was thought of as a steam machine that would give power to the back wheel of a bike. In 1895, the first direct-drive hub motor was developed, which, as a concept, still remains today. In 1897, the first idea for a mid-drive system was born, but wasn’t quite a finished idea. In 1898, the idea was developed of a direct-drive motor that is concentric with a shaft that powers a rotor atop the rear tire to make a friction drive. As decades went on, other concepts for e-bikes were developed, using drive systems only in the front wheel or the back wheel. FAZUA is launching the future of e-bikes in 2015 with what the company calls the mid-drive 2.0. It’s a mid-drive system with an integrated gear reduction that is smaller, lighter, and integrated in the bike so the e-bike actually still looks and feels like a bike – because it actually still is a bike.
