Zero-backlash coupling designs include safety-, metal bellows-, and servo insert-type couplings. The safety couplings use a pre-stressed Bellville spring to disengage servomotors within 2 to 4 msec, compared to a full second for conventional couplings. Metal bellows couplings are designed with high torsional stiffness and low inertia, avoiding the resonance problems of many high performance drives. And servo insert-type couplings increase dampening without deformation. Rimtec Corp., FAX (630) 325-1404.
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
