  • Tolerancing helical springs
    the springs have no control over raw-material properties so they must compensate for the variations during manufacturing. Most spring-coiler machines, notably compression-spring formers, use standard tooling to vary factors such as coil count, pitch, body diameter, and wire feed. Typically, spring rate (lb...

Free length. Gradient. Heat setting. Helical springs. Hooks. Hysteresis. Initial tension. Loops. Mean...
  • Barely scratching the engineered surface
    Emerging engineered-surface treatments work at the micron scale to boost load capacity of bearings, gears, and other components. Tests on helical gears (case carburized + ground) in automatictransmission fluid at constant pitch-line velocity 7,400 fpm. Contact stresses ranged from 190 to 261 ksi...
  • About Ball Screws
    A ball bearing screw is just that: a screw which runs on ball bearings. The screw and nut have matching helical grooves or races, and the ball bearings recirculate in these races. There is no physical contact between the screw and the nut. As the screw or nut rotates, and the rolling balls reach...
  • What to look for in a servocoupling
    continuous helical cut about their OD spanning several rotations. They are highly flexible, transmit low bearing loads, and tolerate angular misalignment or axial motion. Parallel misalignment makes the coupling beam bend simultaneously in two directions, which develops high stresses and shortens...
  • Worm-gear reducers reach new heights
    Design enhancements improve efficiency and eliminate leaks. Worm gearboxes are noted for reliable power transmission. Computer-aided assembly of the Morse Raider gearbox eliminates effects of cumulative manufacturing tolerances and helps maximize operating efficiency. The unit also features...
  • Rotary Seal Lip Design and Geometry
    be molded onto the sealing lip during the manufacturing process creating a hydrodynamic seal.  Hydrodynamic seal - a specially designed seal that features helical ribs, cross etched designs or grooves molded onto the airside of an elastomeric sealing lip.  These helices force fluid back...
  • Die-Cast Zinc Solves Assembly Woes
    the shaft in one step, assembly becomes part of the manufacturing process. Likewise, a two-piece cam and steel shaft assebly can be redesigned so that instead of press fitting the prefabricated cam to the steel shaft, the zinc alloy is cast in the shape of the cam directly onto the steel shaft. The alloy's...
  • Molecular modeling in CAD
    , and smaller yet. At some point, however, it will no longer be feasible to drive technological advance by miniaturizing macroscale products and processes. After all, they can only get so small. Advanced nanotechnology will then come into play. Instead of manufacturing equipment altering material from the top...
