4 Overview

4.1 Use factor When no load spectrum is available, the use factor KA can be determined from empirical data from similar machines. At this point, the use factor KA depends on The operating mode of the prime mover and the working machine. See Appendix B for the value of KA. 4.2 Load spectrum and stress load spectrum Load fluctuations caused during operation, during start-up, or near critical speeds can cause stress in the gear train to change. Chemical. The magnitude and frequency of load changes depend on the work machine, prime mover (or motor), and the mass elastic characteristics of the drive train. To determine the variable load (or variable stress), the following methods can be used. ---Measure the working load on a specific testing machine; ......
