摘要: A compressor blade vibration reduction mechanism for a high-speed radial impeller for minimizing fatigue failures from various excitation sources. The vibration reduction mechanism includes a plurality of loose-fitting lashing pins coupling each impeller blade to an adjacent impeller blade. Each lashing pin extends through a first aperture in a blade located adjacent to the blade tip and through a second aperture of an adjacent blade. The second aperture of each blade is located a greater distance from the leading edge of the blade than the first aperture. The second aperture is located in an area of the blade having lower vibration during operation than the blade location where the first aperture is located.

摘要: A bearing apparatus for reducing vibrations in a compressor shaft (17) carrying a rotating compressor (10) is provided. The bearing apparatus comprises a first bearing (14) for supporting the shaft (17) and a second bearing (13) spaced outboard from the first bearing (14) for producing a moment on the shaft and additional damping counter to the direction of vibrations.
