Kinematic FB | Add Gearing FB

Why use a Gearing Function-Block?

See also Gearing FB dialog-box

Terminology and Definitions

Function-Block :


A Function-Block has an input-connector and an output-connector.

A Function-Blocks modifies data at its input-connector to give different data at its output-connector. Different Function-Blocks modify data in different ways.

Gearing FB :

The default output from a Gearing FB is equal to the input.

The Gearing FB has 3 parameters. Gearing Ratio is the parameter that multiplies the input.

Also, you can add a constant value to the data before or after the Gearing Ratio is applied.

You can enter the Gearing Ratio as a ratio of two integers, or as a real number.

Gearing FB - the function ...

The Gearing FB applies a linear equation.

The linear equation is:

Output motion-value = (1r * (Input motion-value + 2r)) + 3r

Use the Gearing FB dialog-box to edit the parameters Red-14-1bRed-14-2Red-14-3.

Add Gearing FB

Add :

STEP 1: Add the Gearing FB to the graphic-area

Add Gearing FB

1.Click Kinematics FB toolbar > Gearing FB


1.Click Add menu > Add Gearing FB


2.Click the graphic-area

The Gearing FB is now in the graphic-area (and Assembly-Tree).

Edit :

STEP 2: Open the Gearing FB dialog-box

1.Double-click a Gearing FB in the graphic-area or Assembly-Tree

- or -

1.See How to Open a Dialog-Box

Dialog :

STEP 3: See Gearing FB dialog-box

Notes :

The default parameters in the Gearing FB do not change the motion-values at the output-connector.

Use a Gearing Ratio of –1 to reverse the direction of a Crank.

Connect a Gearing FB to the input of a Motion FB to change the frequency of a motion.

Connect a Motion FB to the input of a Gearing FB to change the amplitude and/or direction of a motion.
