E This catalogue presents BONFIGLIOLI RIDUTTORI’s range of Series 300 modular planetary gearboxes. The range has been expanded and integrated with new sizes, technical improvements and enhanced modularity right through to the larger sizes. This feature signifies greater flexibility in internal production to ensure quick availability of products in the sizes and types requested either directly from the company or from the many affiliates belonging to the BONFIGLIOLI sales network in various countries around the world. The gearboxes are tested in conformity with the following standards: ISO 6336...

The 300 series consist of a range of multi-purpose planetary gearboxes that can be operated by electric motors. Basic features are: • 20 frame sizes of modular design • output torque up to 11,388,260 lb»in • transmissible power up to 14000 hp • ratios from 3.4:1 to 5234:1 • versions: - in-line with 1 to 4 reductions - right angle (spiral bevel gear set into first stage) with 2 to 4 reductions • combinations with: - worm gear units - bevel-helical gear units • flange, foot and shaft mounting arrangements • slow output shafts: keyed, splined male, splined hollow, shrink disk mounted • input adaptors...

The following paragraphs contain information on essential elements for selection and correct use of gearmotors. 6.1 Reference torque T2REF [lb»in] It is the significant value for the size. It is equivalent to the maximum value of nominal torque Tn2 for a life factor n2 x h = 10000 (referred to single stage configuration L1). 6.2 Rated output torque Tn2 [lb»in] It is the output torque which the gearbox can transmit with steady load under working condition specified in the calculation method.

Maximun torque T2max [lb•in] 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 Tr2 [lb•in] The torque drawn by the application. It must always be equal to or less than rated output torque Tn2 for the gearbox under study. Input rated power Pn1 [hp] Pn1 is the maximum power that can be safely applied to the gearbox when the same is operated: - at a n1 drive...

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 P1: Indicative values for the efficiency are listed in the chart here after. 9 REDUCTION RATIO i 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 ANGULAR SPEED 10.1 Input speed n1 [rpm] 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 in the gearbox...

12 SERVICE FACTOR REQUESTED BY APPLICATION fS' GJ 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
