VARIABLE MOUNTING ANGLE BLADE GUIDING DEVICE

PROBLEM TO BE SOLVED: To provide a simple and highly reliable guiding device enabling to rotationally drive a blade without generating stress and suppressing wear of a rolling element by eliminating friction especially for a variable mounting angle blade in a compressor of a turbo engine. SOLUTION:...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a simple and highly reliable guiding device enabling to rotationally drive a blade without generating stress and suppressing wear of a rolling element by eliminating friction especially for a variable mounting angle blade in a compressor of a turbo engine. SOLUTION: The blade is mounted on a cylindrical housing 10 of a cowling. The housing 10 includes a pivot composed of a cylindrical axial direction rear part 6 rotationally guided around a shaft by bearings. The bearings are thrust roller bearings 14, 15 provided with tapered rollers 17 and axes of the roller are set roughly perpendicular to a rotation axis of the blades. COPYRIGHT: (C)2005,JPO&NCIPI
