But they are capable of providing only a specific number of fixed gear ratios. Normally chosen for applications involving heavy loads...
  • Torque motors do the trick
    the magnetic field within the motor, thereby eliminating the need for special nonferrous assembly areas, and preventing damage to the rotor from metal scraps and loose screws. Torque motors are designed as direct drives. They eliminate the need for gearboxes, worm-gear drives, and other...
  • Torque, Speed, and Yogurt Cups
    closes, the mechanism again switches back to a high gear ratio to deliver 382 tons of clamping force. TSL developers say the dynamics of the drivetrain posed a challenging design problem. The two servomotors moving the platen had to share torque and not fight each other while driving the load...
  • Time, torque, and inertia
    might mitigate the need for an oversized motor. Adding a gear reducer also boosts system cycle time by the gear-reduction ratio, usually not a problem with large loads. The benefit is that torque is multiplied by the ratio of the gear reducer (minus frictional losses) and reflected inertia drops...

  • Software puts teeth into gear design
    , a presizing module lets users size gears for a particular transmission by typing in minimal inputs. These might include pressure angle, helix angle, nominal ratio (the reduction ratio for the entire gear set), service life, power, torque, and speed. Users also select the material of each gear from...

As relative speeds...
  • High-performance gear reducers keep pace with latest servomotors
    Modern ac servomotors built with high-energy density, rare-earth magnets, and powered by sophisticated controls, produce significantly higher torque at higher speeds than conventional models. Because there are more gear teeth in mesh, planetary gear reducers, for a given ratio and volume, have...
