• Fiber Optic White Paper
  the cables. Early connectors suffered from several deficiencies, including high data loss,. misalignment of fibers, damage due to connection tightness, and lack of repeatability, which is. the ability to connect and re-connect many times without an increase in data losses. Current fiber connectors have...
• Taking torque around corners
  in these devices keep friction losses low and efficiencies high. However, a relatively low torque capacity limits their use. have almost no limitation on misalignment. Some can work when the direction of motion is skewed 180 . Flexible shafts also do a good job of isolating driven-unit vibration from the drive...
• What to look for in a servocoupling
  of the spider itself. Doing so will cause a loss of preload and permit backlash. Curved-jaw couplings can operate at speeds to 40,000 rpm or more. They handle small amounts of axial motion, though excessive parallel and angular misalignment raises bearing loads beyond that of most other types...
• Stable Bolted Joints
  a firm, strong connection, materials that are stable in the environment, stable geometry, and appropriate stresses in the parts, including a correct clamping force. Bolted joints should prevent slip, separation, vibration, misalignment, and wear of parts. Joints and bolts must. Stable Bolted Joints...
• A few guidelines for figuring pneumatic-actuator load requirements
  all produce internal friction. The force loss is typically 1 to 10 psi of theoretical force output of the cylinder, depending on the type of seal. Cylinders with side loads, misalignment, or specialty features have even higher internal friction. Remember that cylinders convert pressure to linear...
• Fiber-Optic Connections
  is designed to prevent damage to the fiber end finish. But the gap causes losses from Fresnel reflection and from the spreading of light from the fiber end. To reduce these losses, some manufacturers fill the gap with a material having a refractive index close to that of the fibers. Misalignment...
• Designed High Reliability Medical Connectors
  helps reduce electrical resistance while addressing misalignment issues, making the contact system much more forgiving. Along with the high durability of mating cycles possible with this design, the contact system offers higher performance in harsh or critical environments. A spring probe system houses...
• Repetitive Pulse Application of Self-Healing High Voltage Capacitors (.pdf)
  becomes more critical. expand their operational envelope. Areas of research (Misalignment will result in capacitance variation. include "hybrid" electrode systems, integrated cooling, between the series capacitances, which results in variation. segmented electrodes, and higher temperature dielectrics...
• Vibration Analysis Case Study - Bearing Failure Avoided (.pdf)
  : The highest peak we found was at 15,233 cpm or approximately 12.69. times the motors operating speed (15,233 cpm/1200 cpm). This peak. was obviously not a result of rotor bars (30x-60x rpm), motor cooling fan. blade passing frequency (Nx), imbalance (1x) or even misalignment. (1x/2x...
