No headersCalculates, designs, and checks clevis pin joints for pin strength, minimum diameter, and part materials.
Clevis pins are used for detachable, rotating connections of mechanical parts. As a rule, these connections transfer only transversal forces acting perpendicularly on the clevis pin axis. Clevis pins are generally fitted with a clearance to form coupled connections (rod-clevis couplings). Clevis pins can also be used for short axles of pulleys, travel wheels, and so on. The H11/h11, H10/h8, H8/f8, H8/h8, D11/h11, D9/h8 fitting methods are most frequently used. Connecting clevis pins should be secured against axial movement by means of cotter pins, flexible safety rings, nuts, adjusting rings, and so on. Standardized clevis pins are produced in versions with or without heads, in which case they are provided with holes for cotter pins.

Clevis Pin Generator - Design tab
Sets parameters for design of a clevis pin.
You need to be connected to the Content Center server and Content Center must be configured on your computers to work with Clevis Pin Generator. If you are not connected to the Content Center, the Items area where you select the pin is grayed out.
See the Content Center Help, or Manage libraries across design workgroups Help to learn how to use the Content Center.
This section is used for designing a clevis pin connection. | |
First, the placement selection must be done. According to the selected placement options, the generator chooses the number of holes or offers to select additional holes or add virtual holes. To begin populating the clevis pin connection, you must follow the instructions provided under the Items list "Click to select pin." When you click this area of the selection list, a filtered list of available pin content (from Content Center) based upon previously set Hole Diameter settings is displayed. | |
Each of the components is editable: | |
| Displays the Custom Properties dialog box where you can change part parameters (length of clevis pin, clevis pin diameter, and so on). |
| Deletes the component. |
| Displays a dialog box where you can select from filtered Content Center items. |

Clevis Pin Generator - Calculation tab
This tab extends the Design tab. You can calculate generator data based on selections in the Design tab.
Access: |  and click the Calculation tab. |
Select the calculation method. It determines which parameters are input parameters and which parameters to calculate. | |
Clevis Pin Design | Designs the optimum clevis pin dimensions for the specified load, dimensions and joint properties. |
Check Calculation | Strength check for the specified load, dimensions, and joint properties. |
Service Factor | Represents a Type of Loading and type of Mounting. The allowed material value is lowered according to the selected type. Click |
Desired Safety | With regards to accuracy and credibility of input information, importance of the coupling, quality of production and accuracy of the calculation, it is chosen in a range from 1.5 to 10. |
Warning: Strength parameters of material are determined empirically and reflect minimum values applicable for a group of materials. Although these values are close to the values obtained using measurement of particular materials, we recommend in cases of final calculations to use parameters of material according to the material sheet or specifications of the producer. | |
Material | You can specify your own material values or select a material from Material Database. If a material is selected from the Material Database, its values are inserted automatically into the following 3 edit fields, and the edit fields are locked. To unlock the field, clear the check box. |
Allowable Bending Stress | Specifies allowable pin bending stress used in calculation. The clevis pin is checked for bending during the strength check. |
Allowable Shear Stress | Specifies allowable pin shear stress used in calculation. The clevis is checked for shear during the strength check. |
Material | You can specify your own material values or select a material from the Material Database. If a material is selected from the Material Database, its values are inserted into the following 3 edit fields, and the edit fields are locked. To unlock the field clear the box. |
Allowable Pressure | Enters the allowable pressure of the clevis pin material with the least quality in the Joint Properties group. The clevis is checked for pressure during the strength check. |
Material | You can specify your own material values or select a material from Material Database. If a material is selected from Material Database, its values are inserted into the following 3 edit fields, and the edit fields are locked. To unlock the field clear the box. |
Allowable Pressure | Enter the allowable pressure of the rod material with the least quality in the Joint Properties group. The rod is checked for pressure during the strength check. |
To display the Results area on the right side of the Calculation tab, double-click the double line on the right or click the chevron. |
The area displays the calculated values and the clevis pin 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. |
Displays the list of factors and appropriate values.
To edit the field manually, you can enter the value in the Calculation tab, or you can select a value from the table.
To insert a value on the Calculation tab, click the white field with a value, and click OK.
| Access: | On the ribbon, click the Design tab, Fasten panel, select any Pin Generator. On the Calculation tab, click |
Pernament Fit
Specifies the overall effect of manufacturing and operational parameters upon connection loading capacity reduction in terms of allowable deformation of contact surfaces. Its value depends on the pin type and connection loading character. With regards to the mentioned parameters, the literature gives values of the coefficient in a range from 1 to 3.
Running Fit
Specifies the overall effect of manufacturing and operational parameters upon reduction of the loading capacity of a pin loaded with shearing or bending stress. Its value depends on the pin type and connection loading character. With regards to the mentioned parameters, the literature gives values of the coefficient in a range from 1 to 3.
OK | Confirms the selection and closes the dialog box. Includes the value in the calculation. |
Cancel | Closes the dialog box. |
