Shaft tutorial

This tutorial gives step by step instructions to design and create a model of shaft. No prior experience of using QY CAD or Engineering Reference is required for this tutorial. However an engineering knowledge on the design of shafts will be useful.

Each step in the tutorial demonstrates the task to be performed with GUI (Graphical User Interface) of Engineering Reference. Some tasks may require interaction with QY CAD also.

This tutorial should take about 15 min to complete.

In this tutorial you design and create a model of shaft with the following specifications.

Force No 1,2 and 3 are located at 75 mm, 100 mm and 140 mm respectively from the left.

The details of the Sections are as follows:

The details of the Forces are as follows:

In this tutorial you will:

• Start QY CAD and Engineering Reference

• Create and edit sections

• Edit supports

• Create and edit forces

• Review results

• Create the 3D model

• Start QY CAD.

• Click the Application button→New→ISO Assembly.

• Click the Tools tab→Environs group→Engineering Reference→Shaft Designer.

• Ensure the Design Parameters tab is active.

  By default there are 6 sections for the shaft. You require only 4 sections for creating shaft as per this tutorial. So you will go ahead and delete two sections.

• Click the Delete button from Shaft Parameters area to delete the current selected section. Click to know how to identify current selected section.

• Click the Delete button to delete one more section. Now you have four sections as required and you can set the type of each section.

• Make sure that the Section parameter is set to 1 to edit the type of section for the first section. Use the Section Type option from the Shaft Parameters area to define the type of each section.

• Select Keyway from the list of section types.

• Set the Length and Diameter of the section through the options available in the Shaft Parameters area. Leave the other parameters in this area to default.

• In a similar way define the type for each section and edit the Length and Diameter parameters as in the input table. Next you will edit the supports of the shaft.

The shaft is supported on two supports. One of these support is a hinge (axially rigid) and the other is a roller support. This information is set by default and hence no modification is required for any parameter related to supports. However you can review the parameters in this area to understand the location of each support on a section.

Our next task is to create and edit forces on the shaft.

By default there is one force on the shaft approximately at the mid of the shaft. You can use the Add button to create two more forces. The locations of these forces need to be specified and the properties of each force need to be edited. The Element Number and Distance parameter from the Loads area allow you to set the location of each force on the shaft.

• The first force is to be located at 75 mm from the left end of the shaft. The value of 75 indicates that the force is located on the second section of the shaft (refer the length of first two sections). Set the value of Element Number to 2 and the value of Distance to 15. This indicates that the force is located at 15 mm from the left of second section. This procedure locates the force at the required location. Use the remaining parameters in this area to input the properties of the force as in the force table.

• Similarly set the location of second force on second section and third force on third section.

Next you will calculate and review the results.

• Click on the Calculate button to calculate the results.

The calculated results are displayed in the Calculated Results tab. You can use different options on this tab to review the results of calculation.

• Click Create to create the 3D shaft model

This concludes the tutorial. In this tutorial you have learned how to use Shaft Module to design and create a 3D model of shaft.
