Final answer:
To determine the suitable pulley diameter and the number of belts required for the given scenario, use the formula for speed ratio in a belt drive system. Calculate the diameter of the driven pulley and use the center distance between the pulley centers to calculate the belt length. Consider the expected use and select a suitable belt type based on the power and tension requirements.
Step-by-step explanation:
To determine the suitable pulley diameter and the number of belts required for the given scenario, we can use the formula for speed ratio in a belt drive system:
Speed Ratio = (N1/N2) = (D2/D1)
Where N1 is the rotational speed of the driver pulley, N2 is the rotational speed of the driven pulley, D1 is the diameter of the driver pulley, and D2 is the diameter of the driven pulley.
In this case, the driver pulley (connected to the four-cylinder diesel engine) is running at 1600 rpm and the driven pulley (connected to the agricultural machine) is running at 760 rpm.
We can rearrange the formula to find the diameter of the driven pulley:
D2 = (N2/N1) * D1
By substituting the values, we get:
D2 = (760/1600) * D1
Given that the center distance between the pulley centers is approximately 1m, we can calculate the belt length using the formula:
Belt Length = 2 * Distance + (π/2) * (D1 + D2)
Considering the expected use of less than 10 h per day, we can select a suitable belt type based on the power and tension requirements.
Using these calculations and considering the specific requirements of the agricultural machine, a suitable pulley diameter and the type and number of belts can be determined.
