Wpu Two Stage Mill Gear Unit

We are connected in making and supplying of WPU Two Stage Mill Gear Units in Kanchipuram, Tamil Nadu, India. The compact 2-stage MAAG WPU bevel and planetary gearbox transmits the power from the electric motor to the grinding table. At the same time, it reduces the speed of the electric motor to the desired speed of the grinding table and changes the horizontal input axis to a vertical output axis. The WPU two-stage gearbox also supports the grinding table, mounted on the output disc. An external oil supply unit lubricates and cools the gearbox.

Casing with internally toothed ring gear
The MAAG WPU gear unit casing consists of a robust welded steel structure. The fixed ring gear is bolted to the casing so that reliable torque transmission is guaranteed. The grinding load including grinding table weight is transmitted straight to the foundation via the tilting-pad thrust bearing and the casing wall.

Gearing
The toothed flanks of the sun pinions have both profile and longitudinal modifications to fully compensate for deformations of the sun pinion and planet wheels occuring under load. This method guarantees optimum tooth flank contact and very long life cycle.
