  • Fundamentals of Helical Gears
    In Figure 5-2 the gear train has a difference of numbers of teeth of only 1; z1 = 30 and z2 = 31. This results in a reduction ratio of 1/30. SECTION 6 HELICAL GEARS. The helical gear differs from the spur gear in that its teeth are twisted along a helical path in the axial direction. It resembles
  • No more "girlie man " gears
    . have all spec'd plastic over metal in recent electronic-parkingbrake gears. The brakes employ 1.2-in. (30-mm) spur gears made from Fortron linear polyphenylene sulfide (PPS). A motor-drive belt powers the gear that drives a transmission for actuating the rear brakes. Designers chose Fortron PPS
  • Gearing Up: The Ins-and-Outs of Gears
    Are all gears really alike? The answer is definitely no! There are four basic styles of gears. *Spur Gear: The spur gear has a helix angle of 0°. *Helical Gear: This is an angle toothed gear. The angle can vary from application to application usually between 1°-45°. *Worm Gear: Worm gears are found
  • SATISFYING HIGHER ENERGY EFFICIENCY DEMANDS WITH WORM GEAR REDUCERS
    The continuing escalation of energy costs has increased the emphasis on the efficiency of drives and drive systems. Recently, manufacturers of helical based gearing mislead engineers to believe that worm gears are incapable of. running efficiencies of 90% and higher. As shown in the chart below
  • Spur versus planetary gearheads for dc servomotors
    . Torque capacity of spur types is limited because each gear in the train bears the entire torsional load. Planetary gearheads, in contrast, share the load over multiple planet gears. Here, the input shaft drives a central sun gear which, in turn, drives the planet gears. Each of the planet gears
  • Planetary reducers eliminate machining step to keep costs down
    with three planet gears. Such configurations tend to last longer than parallel-shaft spur geartrains and better handle larger continuous and peak torque. Tough involute gears are pressed net shape from a sinter-hardened, powder metal which eliminates secondary machining and the associated cost. Another
