Robust planetary gearboxes for long service The G3 full line of planetary gearboxes from Zest WEG is among the most robust in the world and capable of running for 10 years before major servicing is required. Manufactured in Brazil by WEG company TGM WEG, these units are now successfully operating in sugar mills in Zimbabwe and Angola.

The TGMWEG G3 boasts a bearing designed for over 100 000 hours of operation and a pioneering electronic monitoring system that checks oil temperature, pressure and vibration variables to ensure the gearbox is not subject to over-torque.

T heG3full lineofplanetarygearboxes fromZestWEG is among theworld’s most robust and capable of running for 10 years before major servicing is required. With an output torque range from 400 kNm to 8 750 kNm, the range boasts bearings designed for over 100 000 hours of operation. These gearboxes are popular in central drive applications in diffusers and sugar mills, where they are also used as pinion-less and assist drives. In addition to their high mechanical ef- ficiency and robust gear and bearing sets, the gearboxes areflexible in their installation. The high performance hydraulic system has quality lubricant oil filtration, with 10 μm absolutefiltrationelements andanair-oil heat exchanger for optimal cooling. The pioneering electronic monitoring system checks oil temperature, pressure and vibration variables to ensure the gearbox is

not subject to over-torque. This guarantees smooth and reliable operation within the established limits, allowing optimum equip- ment usage and reduced maintenance costs. Manufactured in Brazil byWEG company TGM WEG, the leading gearboxes include components that are heat treated in world- class facilities in accordance with API-6 standards. Committed toquality andenviron- mental responsibility, TGMWEGis certified in terms of ISO 9001 and ISO 14001. The com- pany’s modern industrial complex features gear machining centres, milling machines, grinding machines, a bearing manufacturing department, a lubricating oil analysis labo- ratory and an assembly and testing unit for gearboxes and multipliers. With an extensive footprint in the South American market, these units are now successfully operating in sugars mills in Zimbabwe and Angola. www.zestweg.com
