Abstract

The invention relates to a method for lubricating the teeth of a gear unit having a hollow wheel with an inner set of teeth and at least one pinion with an outer set of teeth that meshes with the inner set of teeth, and a gear unit with a hollow wheel with an inner set of teeth and at least one pinion with an outer set of teeth, which meshes with the inner set of teeth. To assure reliable supply of lubricant to the teeth during the operation of the gear unit, the invention proposes that the lubricant is introduced in a targeted way into the interior of the hollow wheel. The invention further proposes a gear unit, which has a device for the targeted delivery of lubricant into the interior of the hollow wheel.
