The Effectiveness of Shrouding on Reducing Meshed Spur Gear Power Loss - Test Results


Reducing power losses to rotorcraft gearboxes, due to windage drag and viscous effects on rotating, meshed gear components would allow gains in areas such as vehicle payload, range, mission type, and fuel consumption. One method used in rotorcraft gearbox design attempts to reduce losses is to use close clearance walls to enclose the gears in both the axial and radial directions. This paper examines using meshed spur gears at four shroud configurations and compares the data to available data.
