Gearboxes used in aviation and other similar demanding applications are very specially designed, held to tight tolerances, and require precise and reliable lubrication. This is in contrast to how gearboxes in heavier, more industrial applications tend to be immersed in lubricant without the need for targeted lubrication.
The delivery of precise, highly accurate and in some cases screened lubricants is usually provided by Lube Nozzles. The Lee Company, with more than 70 years of experience in precision fluid control, is able to offer special nozzle designs to meet most requirements.
In addition to offering single and multi-orifice nozzle designs in a variety of configurations, The Lee Company has the capability to include safety screens for additional protection. Also, Lee HI-BAR safety screens can be integrated directly into the nozzle body, resulting in an extremely robust, one-piece design.
To satisfy the most demanding lubrication requirements, The Lee Company also offers specialty testing for custom flow rates, tolerances, pressures, fluids, temperatures and even flow targeting. Lee Lube Nozzles are available in a wide range of materials including aluminum, stainless steel and titanium or brass, if requested.
Lee Lube Nozzles are suitable for applications such as propeller gearboxes, airframe mounted gearboxes (typically military aircraft, used to connect the air turbine starter to the main engine), engine mounted accessory gearboxes which are used to drive fuel pumps, oil pumps, hydraulic pumps and electric generators. They are also well-suited for main helicopter rotor gearboxes, tail rotor gearboxes and tiltrotor aircraft gearboxes.
