To Specify a Load on a Shaft (AutoCAD Mechanical Toolset)

How to specify a point load, a distributed load, a torque, or a gear load as an input for a shaft calculation.

The instructions on this page assume that you have already displayed the Shaft Calculation dialog box.

Insert a Point Load

  1. In the Select Load section, click .
  2. On the centerline of the shaft, click the position you want to apply the load.
  3. Enter an angle to specify the direction of the load, or press ENTER for the radial direction. The Point Load dialog box displays.
  4. If the point load is a cyclically changing dynamic load, select Dynamic Load. This setting enables you to specify two values for the magnitude of a force (the minimum and maximum values).
  5. In the Resultant tab, specify the properties of the point load.
    Note: If you prefer to resolve the load into components in the x,y and, z directions, use the component tab to specify the load properties.
  6. Click OK.

Insert a Distributed Load

  1. In the Select Load section, click .
  2. On the shaft contour, click the starting position and then the ending position of the distributed load. The Line Load dialog box displays.
  3. If the load is a cyclically changing dynamic load, select Dynamic Load. This setting enables you to specify two values for the magnitude of every force (the minimum and maximum values).
  4. In the Resultant tab, specify the properties of the point load.
    Note: If you prefer to resolve the load into components in the x,y and, z directions, use the component tab to specify the load properties.
  5. Click OK.

Insert a Torque Load

  1. In the Select Load section, click .
  2. On the shaft contour, click the position to apply the torque. The Torque dialog box displays.
  3. If the load is a cyclically changing dynamic load, select Dynamic Load. This setting enables you to specify two values for the magnitude of the torque (the minimum and maximum values).
  4. In the Torque box, specify the magnitude of the torque.
  5. Specify the direction of the torque.
  6. Click OK.

Insert a Gear Load

  1. In the Select Load section, click .
  2. On the centerline, click the position to apply the gear load. The Gear dialog box displays.
  3. If the load is a cyclically changing dynamic load, select Dynamic Motive Power. This setting enables you to specify two values for the magnitude of the torque (the minimum and maximum values).
  4. In the Inputs tab, specify the properties of the gear load.
    Note: If you prefer to resolve the load into components in the x,y and, z directions, use the component tab to specify the load properties.
  5. Click OK.

Change the Properties of a Load

  1. In the Shaft Calculation dialog box, click Edit.
  2. In the drawing area, click the load you want to edit.
  3. Specify the new location of the load. If you do not want to change the location, press ENTER. The dialog box corresponding to the selected load displays.
  4. Specify the properties of the load in the dialog box that is displayed.
  5. Click OK.

Remove a Load

  1. In the Shaft Calculation dialog box, click Erase.
  2. In the drawing area, click the load you want to remove.
  3. Press ENTER.
