Gear rings can be found at e.g. tower cranes, constructions, wind power plants and special machines where they mostly lubricated manually-
The lubricant gets pushed into the gear base or outwards via gear flanks by doing this. The consequences can be imprecision of lubricant distribution in
contact areas, increased wearing, dripping off the lubricant, faulty dosages and a damage for the environment. To prevent these damages, lubrication pinions have been developed. A guarantee of a precise dosage in those contact areas will given. Furthermore there will be a higher durability, costs will decrease due to reduced lubricant use, an extension of service intervals appear as well as a higher system availability.

Procedure: The lubricant will float via the lubrication pump into the axis and further by a bore inside the lubricant pinion teeth's lubrication duct, which is interlocked with the gear ring. While this, all other lubrication pinions are not in contact with any lubrication. The lubricant, flowing out at the gear flanks, is pressed exactly into the gear flanks' contact areas and evenly distributed via the lubrication pinion's rolling motion. The even distribution of lubricant over the whole tooth width is carried out with plates made of cell rubber. The gears are made of metal, are therefore very durable and resistent to all lubricants and environmental influences.
