This tab extends the Design tab. Calculates generator data based on selections on the Design tab.
Access: |
Ribbon: Design tab Power Transmission panel Synchronous Belts and click the Calculation tab. |
Type of Calculation |
|
Select the type of calculation method you want to use. |
|
Strength Check |
Performs strength check analysis for selected belt, belt width, and belt trajectory. The strength check prompts you to increase belt width if transmission layout cannot transmit the load. |
Design Belt Width |
Protects you from selecting a belt width on the Design tab. Instead, it finds the minimum belt width based on load provided, type of belt, and belt trajectory. |
Load |
|
Specifies the load to be transmitted by belt power transmission. Load is entered through power, speed, or torque according to the selected method in the selection list. |
|
Power, Speed Torque |
Calculates the torque according to the power and speed. |
Power, Torque Speed |
Calculates the speed according to the power and torque. |
Torque, Speed Power |
Calculates the power according to the torque and speed. |
Factors |
You can check the Custom box to enter values. Otherwise the factors are determined by generator as described within Engineer's Handbook |
Belt Properties |
You can check the Custom box to enter values. Otherwise the properties are determined from standard data in XML files. These values are recommended as a minimum. Belt manufacturers provide these values within catalogs and they can be different for the same type (size) of the belt among manufacturers. |
Belt Tensioning |
The Tension Factor controls initial installation tension of the belt. There are recommended practices provided by belt manufacturers that can be used. When a belt drive operates under load, tight and slack side develops. The initial tension prevents the slack side from sagging and ensures proper tooth meshing. In most cases, synchronous belts perform best when magnitude of the slack side tension is 10% to 30% of the magnitude of effective pull what results in belt tensioning factor magnitude from 1.1 to 1.3. |
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 current information about belt transmission geometry. 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. |
