Type of Strength Calculation
|
Specifies the calculation method. It determines which parameters you enter, and which parameters are to be calculated. Note: The selection list is enabled only when a pin is selected.
|
|
|
Pin Design |
Designs optimum joint pin dimensions for the indicated load, dimensions and joint properties. |
|
Check Calculation |
Performs a strength check for the specified load, dimensions, and joint properties. |
Loads
|
Loading is entered through power, speed or torque according to the selected method in the pull-down menu. |
|
|
Power, Torque
|
Calculates the speed according to the power and torque. |
|
Torque, Speed
|
Calculates the power according to the torque and speed. |
|
Power, Speed
|
Calculates the torque according to the power and speed. |
Dimensions
|
Pin Diameter |
Choose a diameter of the pin. |
|
Pin Length |
Specifies the length of the pin. |
|
Shaft Diameter |
Enters the diameter of the shaft. Based on this dimension the appropriate pin is selected. You can enter the diameter or measure the diameter in Autodesk Inventor using the options displayed when you click the arrow next to edit field. |
|
Hub Diameter |
Specifies the diameter of the hub according to the part dimensions. If the hub diameter is smaller than the shaft diameter, the diameters turn red. This also indicates that the strength check of the pin is not satisfactory. You can enter the diameter or measure the diameter in Autodesk Inventor using the options displayed when you click the arrow next to edit field. |
|
Note: The values in the edit field that are not satisfactory turn red when you click Calculate.
|
|
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. |
next to edit field to open the Service Factor dialog box where you can select the service factor value. Pin Material
|
Warning: Determines empirically the strength parameters of material and reflects minimum values applicable for a group of materials. Although these values are close to the values obtained using measurement of particular materials, it is recommended in cases of final calculations to use parameters of the material according to the material sheet or specifications of the producer |
|
|
Material |
Specifies material values you enter, or selects a material from the 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 box. |
|
Allowable Shear Stress |
Specifies allowable pin shear stress used in calculation. The joint is checked for shear during the strength check. |
Shaft Material
|
Material |
Specifies material values you enter, or selects a material from the 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 box. |
|
Allowable Pressure |
Specifies the allowable pressure of the shaft material with the least quality in the Joint Properties group. The shaft is checked for pressure during the strength check. |
Hub Material
|
Material |
Specifies material values you enter, or selects a material from the Material Database. If a material is selected from 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 Pressure |
Specifies the allowable pressure of the hub material with the least quality in the Joint Properties group. The hub is checked for pressure during the strength check. |
