Calculating program of the Cylinder Wheel

Calculation is based on standards from SFS manual 24 (1989) SFS 3390 and SFS 4790. The software opens the database view, to which can be filled in calculation values. Calculating result is displayed in the data base, which data can be added to a drawing.

  1. In the data bas view, you will see the predefined data, and you can edit, and select the desired cylinder wheel.
  2. Calculating is performed after modification by moving by the Enter button to the next field. The titles of the edited files is shown by the capital letters. Backwards (previous field) by pressing the Shift+Tab.
  3. If there is a marking F5, in this section is performed value selection, or calculation by the F5 button, and the result is in the field.
  4. Check all fields containing F5, otherwise there can be left old values.
  5. Calculate geometric values (View GEAgeom.f.cyl). Set values:
    • module
    • angle of pressure (20°)
    • pitches (z1 smaller than z2)
    • pitch length (about 16* module)
    • drift angle (about 15°, so the cover is 1.0)
    • profile movement factors (if you has nor defined these, enter x1 about 0.5 and x2 about 0.3)
    • wheel base (as a practical info, about module bigger than wheel base)

      Now you have to focus the desired profile transition factors.

    • set the tooth gap dimension tooth figures closest whole number (between the brackets, and same the diameters of the dimension cylinder.
    • Tooth gap dimension precision is selected by the F5 key opened from the field (polished 5...7 cut 7...10).

      The program asks the tolerance position (recommended FH set)

    • Edge tooth hight, rounding, the rounding radius (program calculates values of the norm, which do not need to edit)
  6. Strength calculation pressing the F2 key ( view GEAload.f.cyl). Set values:
    • power (kW) (if you set the moment, the power F5 key)
    • number of revolutions(r/min)
    • bearing distance (1, gear)
    • acentric + (gear distance between the bearings)
    • Structure resolve (F5 key)
    • position of the touch hatch (F5 key)
    • adapter of the axes (tooth circle fitting either wedge or interference)
    • diameter of the axis ( 1. gear for the bending)

      Check all fields containing F5, otherwise there can be left old values.

  7. Bearing load calculation (GEAlaak.cyl). Set values:
    • bearing distance
    • acentric + (gear distance between the bearings)
    • Bearing load on the FAsum section F5 key.
  8. Stop calculating by the Esc key, and then opens the print menu. Select the desired printing basis.
  9. Tooth values is entered on by one, by selecting the desired print base., as an example GEApict.c1, and exit by selecting the Esc key. Position the calculation data in the desired position in the drawing.

    Other possibility is to read the text file to the drawing.
