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.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
