Sets parameters for calculation of an involute spline.
Access: | Ribbon: Design tab Power Transmission panel Involute Splines |
Dimensions
Specifies basic spline properties. | |
Splines Type | Specifies the spline type you select in the dialog box displayed when you click the arrow next to the Splines Type edit field. Click the spline type, and it is entered into the edit field. |
Note: Types of splines are displayed according to the selected standard, either metric or English, depending on the selected Autodesk Inventor assembly. | |
Spline | Spline dimensions are updated based on the selected spline. |
Length | Specifies the spline length. |
Displays the Tolerances dialog box where you can enter tolerances. |
Shaft Groove
Specifies and places the shaft groove. | |
You can insert the spline based on the existing shaft groove, or create a groove. According to your selection, buttons for placement are enabled in the Shaft Groove box.
| |
Reference 1 | Select cylindrical face. |
Reference 2 | Selects a start face or work plane with the flip option. |
Note: The Flip option is available only if work plane is selected. | |
Orientation | Specifies the orientation plane used for the groove placement on the cylindrical face (automatically selects the orientation plane). |
Note: If a generator encounters a problem, select the orientation plane. | |
Radius | Specifies the radius. |
Hub Groove
Specifies placement of the created hub groove.
| |
Reference 1 | Specifies the start/end planar face or workplane you select. If the program encounters a problem with the end face, select it. |
Reference 2 | Specifies a start point (can be cylindrical edge or work point) with the flip option you select. |
Note: The Flip option is available only if work plane is selected. | |
Orientation | Specifies the orientation plane used for the groove placement on the cylindrical face (automatically selects the orientation plane). |
Radius | Specifies the radius you enter. |
Note: We recommend that you have a hub groove without an inside hole. The designed hub groove creates the hole according to the inserted values. If the hub groove diameter is bigger than the selected diameter, the design fails and the hub groove is not created. |
Select Objects to Generate
Two options define what is inserted: | |
Shaft Groove Generates a shaft groove on the selected geometry. | |
Hub Groove Generates a hub groove on the selected geometry. | |
Note: The curve used in a Spline groove is not truly involute but only a close approximation. | |
By default, both options are enabled. To disable an option by click the icon. | |
Note: If an object (shaft or hub groove) is inserted, it is not possible to change it during an edit. | |
Note: If shaft and hub grooves are inserted, their mutual position is automatically fixed by a constraint so their positions cannot be changed individually. |
Results
To display the Results area on the right side of the Calculation and Design tabs, double-click the double line on the right or click the chevron.
The area displays the calculated values and the spline strength check. Values are calculated when you click Calculate.
The units of the results values can be changed. Double-click the specified value you want to change.
Summary of Messages
Displays the reports about calculation.To open the Summary of Messages area at the bottom of the Calculation and Design tabs, double-click the double line at the bottom of tabs or click the chevron at the bottom of the tabs.
Graphical Preview
A graphic preview of the selected geometry is displayed. You can use grips to specify spline length, for example.
