The invention provides a compound elastic
cantilever type gas
turbine supporting ring vibration reduction and
impact-resistance
assembly, and relates to a compound elastic
cantilever type vibration reduction and
impact-resistance
assembly device. The purpose of the
assembly is to provide a vibration reduction assembly in a
turbine supporting ring structure assembly to achieve the function of vibration reduction and meanwhile require good
impact-resistance performance so that a
turbine rotor is effectively protected and the transmission of
rotor vibration excitation is separated. The
radial deformation of rotor supporting is controlled, the dynamic and static clearance is small, and the impact and
rubbing of
turbine rotor blades are prevented. The assembly includes an adjusting ring, a spherical shaft sleeve, a nut, a compression part, a compensator shell body, a
screw cap, a group of ring-shaped thin plate, a
pipe connecting ring and a guide supporting column. The spherical shaft sleeve, the adjusting ring, the ring-shaped thin plate and the nut are arranged on the outer side wall of the
pipe connecting ring in a sleeving mode, the nut is sleeved with an inner ring of the compression part, the
screw cap is arranged on the inner side wall of the compensator shell body, an outer ring of the compression part is located between the
screw cap and the ring-shaped thin plate, and theguide supporting column is arranged between the compensator shell body and the
pipe connecting ring. The assembly is applied to the field of
shock resistance and buffering.
