PUMP FOR A TURBINE ENGINE

摘要

A pump for a gas turbine engine is provided. The pump includes a first drive track having a spline and a first gear each rigidly attached to a first driveshaft. The pump also includes a second drive track having a second gear rigidly attached to a second driveshaft. The second gear is mechanically coupled to the first gear. Additionally, a first lubrication supply pump is mechanically coupled to the first driveshaft and a second lubrication supply pump is mechanically coupled to the second driveshaft. The first and second lubrication supply pumps are together configured to provide a desired amount of lubrication to the gas turbine engine.
