Type of Strength Calculation
|
Specifies a calculation method you select from the list. It determines which are input parameters and which parameters are to be calculated. Note: The selection list is enabled only when a pin is selected.
|
|
|
Pin Design |
Designs optimum radial 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 roll-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 |
Specifies the diameter of the shaft. Based on this dimension the appropriate pin is selected. You can enter the diameter or measure the diameter in ProdName using the options displayed when you click the arrow next to the edit field. |
|
Hub Diameter |
Specifies a diameter for the hub appropriate 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 ProdName using the options displayed when you click the arrow next to the 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 final calculations to use parameters of material according to the material sheet or specifications of the producer. |
|
|
Material |
Specifies material values you enter or material you select from the Material Database. |
|
If a material is selected from the Material Database, its values are inserted automatically, and the edit fields are locked. To unlock the field clear the check box. |
|
|
Allowable Shear Stress |
Specifies the allowable pin shear stress used in the calculation. The pin is checked for shear during the strength check. |
Shaft Material
|
Material |
Specifies material values you enter or material you select from the Material Database. If a material is selected from the Material Database, its values are inserted automatically, and the edit fields are locked. To unlock the field, clear the check box. |
|
Allowable Pressure |
Enters the allowable pressure of the radial pin material with the least quality in the Joint Properties group. The pin is checked for pressure during the strength check. |
|
Allowable Shear Stress |
Specifies the allowable pin shear stress used in calculation. The radial pin is checked for shear during the strength check. |
Hub Material
|
Material |
Specifies material values you enter or material you select from the Material Database. If a material is selected from the Material Database, its values are inserted automatically, and the edit fields are locked. To unlock the field, clear the check box. |
|
Allowable Pressure |
Enters 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. |
Results
|
To display the Results area on the right side of the Calculation tab, at the bottom of the tab double-click the double line on the right or click the chevron. |
|
The area displays the calculated values and the radial 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. |
