GENERAL INFORMATION The following paragraphs contain information on essential elements for selection and correct use of gearmotors. It is the significant value for the size. It is equivalent to the maximum value of nominal torque Mn2 for a life factor n2 x h = 10000 (referred to single stage configuration L1). 6.2 Rated output torque Mn2 [Nm] It is the output torque which the gearbox can transmit with steady load under working condition specified in the calculation method. ©Bonfiglioli Riduttori

Maximun torque M2max [Nm] It is the output torque that the gearbox can withstand under static or almost static conditions. It is generally meant as a momentary peak load or starting-up torque under load. The values in the tables are valid only in versions with output splined shaft (accessories excluded). Required torque Mr2 [Nm] The torque drawn by the application. It must always be equal to or less than rated output torque Mn2 for the gearbox under study. Input rated power Pn1 [kW] Pn1 is the maximum power that can be safely applied to the gearbox when the same is operated: - at a n1 drive...

CD_8 EFFICIENCY 8.1 Dynamic efficiency nd The parameter is defined as the relationship of the net power delivered to the output shaft P2 to the power applied to the input shaft Pi Indicative values for the efficiency are listed in the chart here after. It is defined as the relationship of the speed the input shaft is driven at and the speed delivered at the output shaft of a gearbox. 10.1 Input speed n1 [min -1] The speed the gearbox is driven at. The value is coincident with the motor speed if this is directly connected to the gearbox. Input speed should never exceed the n1max value listed...

12 SERVICE FACTOR REQUESTED BY APPLICATION fS' It's a coefficient that represents the severity of the application. This factor takes into account, although approximately, the type of load the gearbox operates with, the specific duty cycle as well as the operating daily hours. The table (A4) is of reference when determining the appropriate service factor for the application. Factor resulting by multiplying angular speed at input (n-i) or output (n2) by actual operating working hours h, break times excluded. Life factor is directly proportional to gearbox rpms during the whole duty time
