For this purpose, the factor for driven machine f1 and the peak torque factor f3 can be derived from table 2 on page 1 in accordance with the group of mechanism standard values M1...M8 in table 1 below - depending on the load (state of loading of mechanism L1...L and the duty (classes of utilization of mechanism T0...T. To take into account the load distribution in case of alternating loads within representative period of time , the cubic mean factor is calculated by: 0 1 5 1.0 0.4 0.1 t1 t2 t3T1 P1 T2 P2 T3 P3 0 1.7 3.3 1t1t2t3 5t4.0 0.7 0.4 0.2 0 5 1.0 0.4 t1 t2 0 9 1.0 0.8 t1 t2L1 L2 L3 L4 *) Only few typical cases of use are shown, by way of guidance, in this column. If the system is driven via an electric or hydraulic motor, factor for prime mover f2 = 1 may be provided. The factors shown on page 1 are empirical values. Prereq uisite for their application is that the machinery and equipment menti oned correspond to generally accepted design and load speci cations.
