  • Ship's Steering Gear Motor Problem Diagnosed Using IR Technology (.pdf)
    The Queen of Saanich Ro-Ro Passenger Ferry experienced a high temperature bearing problem with one of its main steering gear motors. IR analysis showed the non drive end thrust bearing as the source of the heat being generated. It was thought at the time that the bearing was in failure mode
  • Mechanical torque limiters still make sense
    to prevent machine damage. Both examples use a Mayr EAS-NC 3 torque-limiting clutch. This graph illustrates motor behavior when controls are designed to stop and reverse the drive immediately after a collision. This chart shows torque and reaction times of a machine crash with and without mechanical
  • Hannover Fair focuses on efficiency
    , with energy-saving drives, innovative motors, low-friction bearings, and high-efficiency gears and couplings. MDA will also address the growing use of condition-monitoring systems to identify sources of impending failure early on. By preventing unscheduled downtime, they help ensure safe and reliable factory
  • A Change in Speed Control Strategy Ramps up Production for Steel Company
    adjustments. The TSA team decided to upgrade the speed controls by using a variable speed drive (VSD), but they weren't sure how to size the new motor and drive. They also wanted to make sure the upgrade didn't introduce undue complexity to machine operation.
  • Odd-Shaped Seal Stops Random Leaks
    Canal Winchester, Ohio, expect near-perfect reliability from their Piggyback construction forklifts. Therefore, it was perplexing and disturbing when occasionally and without warning, a Piggyback would blow the drive hose to the front-wheel-drive motor. Hydraulic leaks
  • A century of progress in aircraft materials - Part 2 Metals
    the industry by the end of the next decade, but no one can point to solid evidence that composites are any better than metal, or wood and fabric, for that matter. They might be stronger or lighter, but they're more expensive to make, more difficult to inspect, and trickier to repair. In 1925, Ford Motor Co
  • Sealed vs. Seal-less Pumps: Can One Size Fit All?
    , for both provider and customer. Simple commodity-like components like fittings, seals and motors can be sold using a "short-term" sales strategy like the one above. But pumps are more complex and require engineering to make them perform efficiently and cost-effectively in a fluid system. With a quick
