Oil-Air Lubrication Systems for Open Gear Applications
The open gear oil-air injection lubrication system can remove high points and peaks on the tooth surface, increasing the tooth surface contact rate. This results in a more uniform load distribution on the tooth surface, eliminating localized stress concentrations and extending gear life.

Details
Large open-type gears are primarily used in transmission equipment in raw material industries, such as coal mills and ball mills in power plants, rotary kilns in cement plants, ball mills in mines, dryers in the chemical industry, and drum pulpers in the paper industry.
These gears operate at low speeds and under heavy loads, often accompanied by dust and moisture, leading to metal material loss and consequently, reduced contact area, resulting in gear failure.
An open gear oil-air injection lubrication system consists of the following components: a pneumatic lubrication pump, an oil-air mixing assembly, an air path control assembly, a single-element nozzle assembly, and a PLC electronic control unit.
