GearBox Design Note's

These are notes based on my experience and are a reminder of how piece together designs for gearboxes.

Process to a gear box

• You have a device that can use a gear box (such as a quarry).
• It appears each device will have a random output value associated with it. So you will NOT be able to create a bunch of gear boxes for all quarries as each quarry will have separate output value.
• A device will have an output value containing a column and a range of ratios (e.g. H65-H78). In the case of a quarry, clicking on it (the quarry) will display a menu that provides the output value range needed for a gearbox.
  • The output value contains a letter A through H which indicates the column the last gear must be placed. The last gear is always in row 8.
  • The output value also contains a number range (from the example above H65-H78). The numbers are percentages or ratios (in gearbox design, percentage and ratio mean the same thing). In our example, we are looking for an output value between 65% and 78%.
• Once you know with ratio range, you can go to the Gearbox Ratios page and select a row with a ratio value within your device range.
• Write down or note the Gear Linkage values.
  • The linkage values display gear sizes and mesh connections. So "how" to connect gears, NOT where to place them on the gear design table (that's our job to figure out).
  • As gears go from large to smaller (5/3) ratios go higher (maybe 100% to 120%).
  • As gears go from smaller to larger (3/5) ratios go lower (maybe 120% to 100%).
  • As gears stay the same (3/3) or (4/4) ratios stay constant.
• Go to Gearbox_Assembly_Table and connecting gears using the linkage values and the Constraints and Meshing subsections of Gearbox_Design_Guide page.
• The Analyze option of the gearbox design table menu will display percentages for each working (correctly meshed) gear. If gears are too close you will not see a popup display list, only a message on the Main chat tab.
• Once you have the needed ratio, connect or mesh level 3 or 4 gears to the needed output column (A thru H) and row 8. Remember constraints and meshing rules apply for 3 to 3 (gears must side by side) and 4 to 4 (diagonal).
• Once to row 8, select Analyze from the table menu to be certain the ratio is correct.
• Select Build This Gearbox from the table menu.
  • If you select Build This Gearbox option and do not have the correct gears on you they will be itemized (gear counts, size, metal type) in the Main chat tab.

Example 1

Quarry H65-H78 - using 69% output value

• From the Gearbox Ratios page - gear linkage equals (5/6)*(5/6)
• Table looks like:
  • A1 - Gear level 5
  • A3 - Gear level 6, then stack level 5
  • C3 - Spacer, then stack level 6 (ratio value 69% met and time to get to column H without changing the ratio), stack level 4 gear
  • D4 - Gear level 4, spacer, level 4 (Because in C3 we have a spacer laid first we can place a level gear. This will reduce the number spacers needed for the remainder gears locations.)
  • E5 - Gear level 4
  • F6 - Gear level 4
  • G7 - Gear level 4
  • H8 - Gear level 4

• Analyze to confirm ratio and build to get itemized list of gears needed.

Example 2

2 Quarry solution B441-B507 and F453-F507 - using 463% output value

• From the Gearbox Ratios page - gear linkage equals (5/3)*(5/3)*(5/3)
• Table looks like:
  • A1 - 5
  • B2 - 3-5 (level 3 gear, then stack level 5)
  • C3 - spacer-3-5 (spacer for correct height, level 3 gear, then stack level 5 gear)
  • D4 - 3-spacer-3 (Once we mesh a level 3 gear to the level 5 gear ratio will be met. If we place level 3 gear first we can drive to the needed output columns. Stack level 3, spacer, level 3.)
  • D5 - 3
  • D6 - 3
  • B7 - 3
  • C7 - 3
  • D7 - 3
  • E7 - 3
  • F7 - 3
  • B8 - 3 (output 1)
  • F8 - 3 (output 2)

• Analyze to confirm ratio and build to get itemized list of gears needed.
