Preload Design of Bearings in Helicopter Transmission System
In order to reduce running noise and enhance the stiffness and accuracy of shaft guidance, the bearings often use preload design in some position of the helicopter transmission system. In addition, the preload design of the bearings can compensate for wear in the operation and provide long service life of the bearings. By expatiating on the effect, types, determination and adjustment procedure, it offers reference for the design of preload for bearings.
