    Gearboxes

    Most modern gearboxes are used to increase torque while reducing the speed of a prime mover output shaft

    Reduction ratio calculation
    Output Speed=Motor Speed/Gear Ratio

    Gear Ratios: Up to 20 Ratios from 3:1 to 200:1

      Permissible Overhung Load And Permissible Thrust Load Of Motor

     Permissible Overhung Load • Permissible thrust Load
    • Avoid thrust loads as much as possible. If thrust load is unavoidable, keep it to half or less of the motor mass.
      Allowable Suspension Load Of Motor•Allowable Axial Load
      Permissible Load Inertia For Gearhead J

     • When a high load inertia ( J ) is connected to a gearhead, high torque is exerted instantaneously on the gearhead when starting up in frequent, discontinuous operations ( or when stopped by an electromagnetic brake, or when stopped instantaneously by a brake pack). Excessive impact loads can cause the gearhead or motor damage.
    • The table below gives values for permissible load inertia on the motor shaft. Use the motor and gearhead within these parameters. The permissible inertial load value shown for three-phase motors is the value when reversing after a stop.
    • The permissible load inertia ( J ) on the gearhead output shaft is calculated with the following equation.
    • The life of the gearhead when operating at the permissible inertia load with instantaneous stops of the motors with electromagnetic brakes, brake packs or speed control motors is at least 2 millon cycles.
