Embodiment Construction

[0018] A composite elasticity and damping anti-shock shock absorber for a gas turbine device, including a mounting screw 5, a shock absorber upper cover 1, a shock absorber base 2, and a body vulcanized as a whole between the shock absorber upper cover 1 and the shock absorber base 2 Rubber 3, the above constitutes the basic external square structural features of the shock absorber, which is conducive to the design of different impact stiffnesses in the vertical, horizontal and longitudinal directions; the top of the shock absorber upper cover 1 is provided with a height adjustment nut 4, which is in the shock absorber The upper end surface of the hexagonal height adjustment nut 4 of the upper cover 1 is the installation surface of the gas turbine underframe, and the total height between the installation surface of the gas turbine underframe and the base panel of the hull is adjusted by rotation, and a stop lock is set on the side of the height adjustment nut 4 Tighten the scre...

Abstract

The invention belongs to the technical field of gas turbine equipment and particularly relates to a composite elasticity and damping shock resistance shock absorber of a gas turbine device. The shockabsorber comprises a mounting screw rod, a shock absorber upper cover, a shock absorber base, and integrally vulcanized main body rubber between the shock absorber upper cover and the shock absorber base; a height adjusting nut is arranged at the top of the shock absorber upper cover; a fastening locking screw is arranged on the side face of the height adjusting nut; a middle threaded hole columnand symmetrical lateral threaded hole columns are arranged on the shock absorber upper cover; a transverse isolating block and a middle rubber buffer block are arranged in the shock absorber base; a central isolating rubber ring and symmetrical lateral isolating rubber rings are arranged above the transverse isolating block; the middle threaded hole column is in threaded connection with a centralscrew rod; the lateral threaded hole columns are in threaded connection with a lateral screw rod; and a bottom buffer metal steel wire gauze pad, a belleville spring and a bottom compression resistance rubber pad are sequentially arranged below each of the central screw rod and the lateral screw rod. The shock absorber is used for realizing vibration isolation and underwater explosion impact resistance of the gas turbine device.

Description

Technical field: [0001] The invention belongs to the technical field of gas turbine equipment, and in particular relates to a composite elasticity and damping anti-shock shock absorber for a gas turbine device. Background technique: [0002] As the main power plant of modern ships, especially the gas turbine used on warships, it must not only have good working performance, but also must have strong stealth performance and impact resistance. The use of vibration reduction and noise reduction technology for gas turbines can reduce the danger caused by sound-controlled underwater weapons to J ships, reduce the search and positioning of enemy sonar devices, and improve the acoustic concealment and offensive and defensive capabilities of J ships; Battle cases and real ship underwater explosion impact test results show that the prominent weak link displayed by naval combat ships in underwater explosive environment is the insufficient impact resistance of many important equipment a...
