The usage factor f g The graph below can be used to calculate the usage factor f g according to the working hours on a daily basis. 1,3 1,2 1,1 1 0,9 usage factor f g 0,8 0,7 0,6 0 4 8 12 16 20 24 daily working hours [h] The ambient factor f a By means of the following table it is possible to calculate the f a factor according to the operation conditions. Type of load daily running hours 3 8 24 Light shocks, few insertions, regular movements 0,8 1 1,2 Medium shocks, frequent insertions, regular movements 1 1,2 1,5 High shocks, many insertions, irregular movements 1,2 1,8 2,4 The duration factor f d The duration factor f d is obtained according to the theoretical expected lifetime (expressed in hours). duration factor f d 2,2 2 1,8 1,6 1,4 1,2 1 0,8 0,6 0,4 1000 10000 100000 daily working hours [h] With the equivalent power value P e and according to the angular speeds and the reduction ratio, it is possible to chose on the descriptive tables the size presenting an input power higher that the calculated one. At the same time it is possible to check, through the graph on page 231 the torque necessary on the adjustment worm screw. 238
D – THE INERTIA POWER In case of important accelerations and decelerations it is necessary to calculate the inertia power P J . It is the power necessary to counteract the inertia forces and torques opposed by the system in case of speed changes. First of all it is necessary that the designer calculates the system inertia downstream of the speed modulation gear box J v reducing them to the slow shaft. After that the speed modulation gear box inertia J f must be added, which can be taken from the table below, so that the total inertia J will be obtained. We remind that the inertia moments are expressed in [kg•m 2 ].
