Simple Gear-Trains

A Simple Gear Train is a number of Simple Gear-Pairs in series. Each Shaft has only one gear. Use a Simple Gear Train:

The image to the left shows a schematic of a Simple Gear Train.

Note:

Monobloc Machines

Monobloc machines are frequently used with Filling, Capping, Labelling, Coding, Orientating and many other high speed packaging applications.

The monobloc has a simple gear-train to transmit the motion from one 'head' to the next.

Add a Simple Gear-Pair with an External Mesh - see Option 1 Step 14.1

Here, the number-of-teeth are:

T1=20, T2=40. The Gear Ratio is T1/T2 = 2

The basic rule::

Three Parts, and three Lines, joined together with two Pin-Joints'.

Again, we need three Lines, in three Parts. Join the Parts with Pin-Joints. The Pin-Joints must join Points at the end of each Line.

Gear-Pair 2:

Line 1 and Part 1

Line 1 is the CAD-Line in the Geared-Rocker (output-Gear) of Gear-Pair 1.

Gear-Pair 2:

Line 2 and Part 2

This will be the line-of-centres - it is the Line that joins the gear-centres

It is a new Line in the Base-Part.

1.	Edit the Base-Part

2.	Add a Line

It does not matter how long.

IMPORTANT rule: You must MERGE Point and Point

4.	Select Point and Point at the end of the new Line

Line 3 and Part 3

5.	Add and Join a Part to the end of the new Line, with a Pin-Joint.

The length of Part is not important.

Add Gear-Pair 2

MechDesigner adds two new gears.

A Simple Gear Train does not need one of the Gears of Gear-Pair 2.

We must hide the Gear on the same shaft centre.

This is a MechDesigner trick.

Use the Gear-Pair dialog-box to edit:

2.

Add Line

Merge the start-Point of the Line to the end-Point of the Line-of-Centres in Gear-Pair 2

You can see the new Gear-Pair 3

To 'hide' the Gear we do not want , use the Gear-Pair dialog to edit the:

Also, edit:
