Abstract

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.

Description

technical field [0001] The invention relates to a composite elastic cantilever type vibration damping and anti-shock component device, in particular to a composite elastic cantilever type gas turbine turbine support ring vibration damping and anti-shock component, which is used to realize vibration transmission isolation and impact resistance protection of a gas turbine power turbine rotor system. Background technique [0002] In recent years, with the development of science and technology, the explosive yield and impact duration have increased significantly. The precise calculation mechanism has led to a greatly improved hit rate, and the threat to the ship's electromechanical equipment has become more and more serious. At the same time, with a large number of advanced shipborne instruments such as electronic countermeasures, communication and navigation, the requirements for the environment are more stringent, and a slight shock wave input will lead to a long-term loss of c...
