  • Spur versus planetary gearheads for dc servomotors
    material, especially at high speeds and loads. Here, planetary gearheads have the advantage because oil flying outward from the sun gear is captured by the planet gears and carrier plate. Spur types, on the other hand, tend to fling lubricant off and away from the gears. This is one reason planetary
  • No more "girlie man " gears
    . Fatigue strength curves generated by the P-Gear unit are measured on standard 2-in. test gears. The data shown was taken using gears made from Celcon M15HP acetal copolymer, a high-performance gear material. Plastic gears have had a successful run in automobiles, appliances, office equipment, and power
  • Gearhead Construction and Use
    Gearhead Construction and Use. Spur Gear Type Gearheads. Direction of Rotation. Planetary Gears. Spur Gear Type Gearheads. Spur gear type gearheads are probably the best possible choice for relatively low torque applications. They tend to be less expensive than comparably sized planetary gearheads
  • 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
  • Sometimes it pays to be eccentric
    and consistent torsional stiffness. Designing a system that demands minimal backlash, tight space constraints, or high reduction ratios, often calls for looking beyond traditional spur or helical gearboxes. In fact, less common power-transmission devices can often solve all of these design constraints. Several

    Fig. 5-High Torque Shaft and Spur Gear The high torque shaft and spur gear (Fig. 5) are directly connected to the wind turbine and rotate about the central axis of the high torque shaft.
  • 22. Evaluation of Gear Oils Under Conditions of Boundary Lubrication
    The testing of oils for spur gears can be easily ac- complished in spur gear testing machines with high torque , such as the 1.A.E.- or Niemann-machines [7].

    Another advantage of planetary gearheads over spur gearheads is a higher torque carrying capacity because the torsional loads are shared by multiple planet gears .
