Calculated Values

  • Depending on the mechanism, radial and axial loads may be generated as well as X2 & Y2 values.
  • For example, a Conveyor mechanism will generate a radial load [F2r], and a Rack & Pinion mechanism with a Helix Angle will generate both a radial [F2r] and axial [F2a] load.


How X2 is calculated

  • X2 = Gearbox x2 database value, which is the distance to flange-plane at output
  • Rotary Mechanism with Shaft Loads Defined in Sequence
    • When multiple radial forces and/or X2 values are defined in the sequence, then, an "effective" X2 value is calculated so that the proper tilting moment is applied to the output side of a gearbox connected


How Y2 is calculated

  • Rack & Pinion and Dual Rack & Conveyor:
    • Y2 = Pinion Radius
  • Rotary Mechanism
    • Unbalanced Load
      • Ratio of Unbalanced Load Mass [mUL] wrt Total Mass multiplied by the Unbalanced Load Radius [rUL]
      • Y2 = mUL / (mUL + mDisc + mLoad) * rUL
    • Shaft Loads Defined in Sequence
      • When multiple axial forces and/or Y2 values are defined in the sequence, then, an "effective" Y2 value is calculated so that the proper tilting moment is applied to the output side of a gearbox connected
  • Else Y2 = 0


How Y1 is calculated

  • Transformation Type = Gear
    • Y2 = Drive Gear Radius
  • Else Y2 = 0


How X1 is calculated

  • X1 = Gearbox x1 database value, which is the distance to flange-plane at input

Apply Calculated Values for F2a, F2r

  • When each of the F2a and F2r buttons is selected, the corresponding calculated value(s) are applied as the application required values.
  • When a button is not selected, the application required values can be entered manually.
  • If the gearbox output is not exposed to any shaft loads, then de-select the F2a and F2r buttons and enter 0 for the application required values. Ie. No shaft loads are applied.

Gearbox Rated and Required Values and Utilization

  • The Rated values come from the database values, adjusted for any load factors if applicable
  • Application Required Values can be the calculated or user specified
  • For a Const Velocity segment, Accel and Jerk step values are also not used as Accel and Jerk are always 0
