Various Methods Can Be Used to Determine the Correct Belt Tension, Including the Following
3. Experimental Measurements and Analysis of Results
3.1. Measurement of Belt Slip of Belt Transmission
- n1t—table revolutions of the electric motor driving machine;
- n1s—the actual speed of the motor under the load of the driven part under the given conditions of the tension force F;
- n2—speed without slip on the drive machine;
- it—the theoretical transmission ratio;
- n2s—measured (actual) speed of the driven machine with slip;
- Δn2—slip speed;Δn2 = n2 − n2s
- T—the measured (real) time of the slip revolution [s];
- ξ—specific slip;
- ψ—coefficient of elastic slip;ψ = 1 − ξ
- i—gear ratio in belt transmission;
- Measurement at constant speed of the electric motor and brake load: In this case, the constant speed of the electric motor and the same torque are maintained using the brake. During the measurement, the values of ψ and ξ are obtained at a minimum of five different levels of tensioning force, both during the loading and unloading of the transmission. Based on these values, it is possible to create graphs that show the dependence of the elastic slip coefficient on the tension force value. These data are then processed and entered into the results table.
- Measurement at constant input speed and tension force: In this scenario, constant values of electric motor input speed and tension force are maintained. The measurement focuses on the elastic slip coefficient ψ at different torques of the electric motor. At least five different values of the torque are obtained from the measured input power of the electric motor according to the established procedure, which enables the precise determination of the coefficient ψ.
