2 2/20 Bosch Rexroth AG MOBILE RE 77201/05.06 Description Rexroth MOBILE planetary gearboxes are hydrostatic swing gears. They are suitable for use in excavators and cranes of all types, in ship unloading equipment, forestry equipment and in all applications where accurate positioning is called for. The drive consists of a two or threestage gearbox with an integrated multidisk parking brake, an output pinion as well as a hydraulic motor, preferably from Rexroth. A dedicated team of R&D, design and sales engineers makes sure that the clients' wishes and concepts are quickly translated into technically and economically viable solutions. In their work, they are assisted by modern computer software for gearing design and component optimization. The information provided in this bulletin serves to help you select the planetary gearbox best suited for your application. In addition, our field personnel are available to you to provide advisory services even at the project stage. Rexroth MOBILE twostage hydrostatic compact drive with a multidisk parking brake and a Rexroth plugin motor Lubrication The gearteeth and bearings are splash lubricated. Aside from periodic oil changes, the drive units are maintenancefree. Oil changes are easy to do. The oil brands recommended in the operating manual shall be exclusively used. The change intervals for the relevant application conditions are also given in the operating manual. The pinionside antifriction bearing of the output shaft is greaselubricated for life. Brake The standard supply scope includes a springloaded, hydraulically released multipledisk parking brake arranged on the input side. The multipledisk holding brake is not a service brake. Hydraulic Motors The gearbox is designed for direct flange attachment of a variable or fixed displacement motor (preferably a Rexroth hydraulic motor). If requested, the motor can be supplied along with the gearbox. Gearbox Supply Rexroth MOBILE planetary gearboxes are delivered ready for installation, but without oil filling. The standard gearbox version comes with a priming coat of grey color (similar to RAL 70) and is internally protected with a temporary corrosion preventive that preserves the gearbox for 24 months, if stored in a dry location. External flanges, shaft extensions and mating faces are protected with TECTYL 502 C. Weights, Oil Volumes, Dimensions The specified weights are average figures. As far as oil volumes are concerned, gearbox operators should rely on oil level readings rather than specified oil volumes. Figures and dimensions are not strictly binding. We reserve the right to make changes in line with technical progress. Further Notes As prescribed by statutory provisions, all rotating parts must be protected by guards against accidental contact. Local safety regulations must be complied with. Commissioning and maintenance of the gearboxes must be performed in line with the instructions given in our operating manual.

4 4/20 Bosch Rexroth AG MOBILE RE 77201/05.06 Application Conditions The gearboxes are designed for use at ambient temperatures of between 20 C and + C. Environmental influences such as salt water, salty air, sand, dust, overpressure, heavy vibrations, extreme shocks and ambient temperatures, aggressive fluids and the like may affect the function of the gearbox. All such conditions must be specified so that the gearbox can be designed for safe operation. Gearbox Design The gearbox design is based on many years of practical application experience. The maximum output torques T 2 max indicated under technical data for crane applications relate to FEM Section I, 3rd Edition and Section I (FEM Fédération Européenne de la Manutention), as well as DIN 020, collective load class, service time category T5 corresponding to driver group M5. The reference output speed is 25 revolutions per minute maximum. If the swing drive is to be classified in another driver group, the required output torque must be converted using the K factor (see table). This conversion gives you the maximum admissible output torque for the new driver group selected. Whether or not the chosen overall classification can be met will be determined by the Rexroth gear technology experts. Gearbox Selection T 2 = Output torque T 2K = Corrected output torque K factor according to service time category and collective group given in the table. T 2 K of the gearbox to be selected must be T 2 max (according to this product catalog). Brake The holding torque multiplies with the selected transmission ratio. See also Gearbox Design. T 2 K = T 2 K T Br sta. min = 1,3 T 1 (input torque) A design data sheet for swing drives is reproduced on pages 14 and. Higher Torques For gearboxes transmitting higher torques than those indicated in this product catalog, please contact us.
