|
Type of Calculation |
|
|
Specifies the strength calculation type you want to use. |
|
|
Strength Check |
Performs a strength check analysis for the selected belt, number of belts, and belt trajectory. The strength check prompts you to increase number of belts if transmission layout can't transmit the appropriate load. |
|
Design Number of Belts |
Protects you from selecting the number of belts on the design page. Instead, it gives a recommendation for the number of belts 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 method selected in the list. |
|
|
Power, Speed |
Calculates the torque according to the power and speed. |
|
Power, Torque |
Calculates the speed according to the power and torque. |
|
Torque, Speed |
Calculates the power according to the torque and speed. |
|
Factors |
|
When the Custom box is selected, you must enter values. Otherwise, the factors are determined by the generator as described within Engineer's Handbook |
|
Belt Properties |
|
When the Custom box is selected, you must 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 may be different for the same type (size) of the belt among manufacturers. |
|
Belt Tensioning |
|
The Tension Factor to controls initial installation tension of the belt. Follow the practices recommended by the belt manufacturers. If a factor is not set according to the recommendations, the belt horse power rating might not calculate correctly. The installation tension has a big impact on efficiency and belt slip. There is commonly used magnitude of belt tensioning factor from 1.0 up to 1.5. High installation tension might decrease belt lifetime. |

Efficiency torque factor |
Controls the edit efficiency to compute correct output power and torque on driven pulleys. This factor describes the level of the quality of belt transmission. The loss of energy that leads to decreased output torque is considered. Factors like belt deformation energy, wind turbulence in grooves, and so on take place. The power loss caused by slip is not included here and it is determined by the generator separately. The combination of these 2 factors results in final belt drive efficiency. |
|
Modify friction with belt speed |
Calculates friction. With increased belt speed the friction might change. The value provided describes how much the friction changes with belt speed. |
