NEW TRANSMISSION TECH How is such a signifi cant increase in power density possible? The ZF engineers have utilised the newest development tools, designing and evaluating all components in the gearbox according to the latest fi ndings in transmission technology. This applies, in particular, to


the geometry and qualities of the individual gears, the choice of materials, improved technological properties and the revision of the structural components for maximum torque and power transmission. Adapting the required bearing concepts to the increased service life or suitable sealing and lubrication systems also plays a part.


A DOUBLE WIN OEMs have two choices with Redulus4F


gearbox service life. The other option for the OEM is to


select a gearbox that can be up to two sizes smaller. The advantages are clear: lower weight, improved handling, saving on installation space with the option of smaller roller distances, better maintenance access around the rollers, and reduced investments. ZF says it can meet the high


requirements for development and delivery times for the respective application-specifi c solutions with its optimised confi guration concept.


MAXIMISING COMPETITIVENESS The maintenance-friendly design for assembly/disassembly, borescope inspections of the Redulus4F


. One is to maintain the


existing size but increase the torque rating compared with the previous generation of these gearboxes. This results in a considerably higher output capacity of the HPGR and improved


of our customers when using our drives.” ZF states it has mastered this


challenge excellently with the Redulus4F


series but cannot and will


not rest on its laurels. As the saying goes: ‘after optimisation is before optimisation’. These are the requirements for the next generation of the company’s industrial gearboxes.


gearboxes,


and the proven condition monitoring system ZF ProVID considered during development, also enable quick intervention in an emergency to avoid lengthy downtimes. Markus Christen, project manager , adds: “The developments


for Redulus4F


and innovations ultimately have one goal: maintaining the competitiveness
