Abstract (en)
[origin: US4502841A] An axial locking device for blades of a fan, each blade including a root of dovetail or other re-entrant form engageable by axial sliding in corresponding grooves of the rim of the fan disc. A locking member is provided in the form of a key of parallelepiped form abutting the root of the blade. The key is locked against radially outward motion by a peripheral extension from one longer edge which engages a tab member having a portion which is secured to a front face of the fan rim. The key engages radial slots in the rim and in an alternative embodiment, the key is secured radially by a bolt which passes through a forward part of the rim, an end portion of the key and into a tapped bore of the main body of the rim.
