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.

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.

Reverse Engineering

Finding replacement metal bellows components is easier with Servometer's time saving reverse engineering guidelines. Download White Paper Reverse Engineering guidelines Today's design engineers often find themselves in the uncomfortable predicament of replacing legacy parts or parts that have become obsolete. This predicament is often the result of undocumented drawings, part numbers, or specifications. In many cases, the original designer is no longer available. Whatever the reasons, it is often the job of the design engineer to propose a solution using outdated technology and resources or insufficient information. This paper offers hands on reverse engineering guidelines and provides a solution to finding the ideal replacement bellows for your application.

Electroforming Basics

Electroforming is the process of depositing thin layers of metal onto a mandrel through electroplating, dissolving the mandrel chemically, and leaving the plating as the final electroformed product. Learn how electroformed components are manufactured and how they can be applied to a variety of applications.
