A pioneer of modern gear technology FLSmidth MAAG Gear was founded in 1913 and quickly expanded into an international group that now has almost 100 years of experience in manufacturing gear units. Since introducing the technology of mill gear units to the cement industry with great success in 1966, we have sold over 6000 MAAG™ gear units and 1000 girth gears. The company At the FLSmidth MAAG Gear headquarters in Winterthur, Switzerland, more than 100 employees work in development, design, finance, project management, sales, customer service and marketing. Production and assembly takes place...

Introduction Modern vertical roller mills are becoming increasingly larger with a higher performance densities and now require gear units that can transfer higher levels of torque. The grinding table speed that is needed for an optimum grinding process is determined by the output drive speed of the gear unit. Slower table rotating speeds at the same gear unit input speeds increase the total gear ratios that are required. The new design of the three-stage MAAGTM WPV gear unit meets all of these requirements. New design The WPV three-stage bevel and planetary gear units, all of which...

Planetary system The planetary system is a proven concept and offers different advantages. Due to the torque split, the second stage has only 75% of the torque. An optimised force-flow is achieved by the self centring inner gear and sun pinion. Smaller gear wheels can be used through the use of the torque split and 4 planets in the second stage. MAAG Gear has managed to keep to only eight different types of gear units in the WPV new design. All of them are able to fulfill the requirements of the various mill manufacturers. Within the design size and gear unit type itself, a further...

Slide bearings Slide bearings stand out due to short delivery time and an unlimited lifetime which ensures high availability of the plant. Higher damping compared to anti-friction bearings results in less vibration. In the unlikely case of a damage, local emergency repair is possible. The slide bearings are easy to install and highly service friendly. Lubrication system Lubrication system The gear unit is lubricated by a closed circuit oil system. The oil tank serves as a platform on which all the assemblies and components such as motor pumps (high and low pressure), switchable double oil...
