Gear apparatus for a centrifuge including a drive shaft having two hollow longitudinal channels for lubricating the gear apparatus via an associated lubricant compensating system

摘要

A gear apparatus for a solid-bowl screw centrifuge. The gear apparatus includes a shaft, a gear, and a bearing. The centrifuge includies a drum and a screw, both of which are configured to be driven. The screw is further configured to be driven at a different rotational speed relative to the drum. The gear apparatus is connected between one or more drive motors and the screw and the drum. The gear apparatus is continuously filled with a lubricant and includes a hollow drive shaft having two hollow longitudinal channels extending in an axial direction. Also included is a lubricant compensating system having a lubricant compensating container connected via a line and a rotary lead-through for lubricating the bearing through the two hollow longitudinal channels.
