Problems solved by technology

Although there is a certain vibration isolation effect, but the degree is limited
In addition, the existing vibration isolation method mainly adopts elastic installation vibration isolation between the mechanical equipment and the basic structure, that is, the vibration isolator is arranged between the box and the foundation to reduce the vibration transmitted from the excitation source to the basic structure. poor effect

Embodiment Construction

[0011] With reference to the figures, a cylindrical double shell structure with a vibration isolation system includes a box body and a vibration isolator 2. The box body includes an outer shell 1 and an inner shell 3, and an outer shell 1 and an inner shell. The layer shells 3 are connected by a vibration isolator 2. The vibration isolator 2 includes a sleeve 201, a rubber metal ring 202, and a mandrel 203. The sleeve 201 is connected to the inner shell 3, the mandrel 203 is connected to the outer shell 1, and the mandrel 203 is connected to the sleeve 201. A rubber metal ring 202 is arranged between. The outer shell 1 and the inner shell 3 are both cylindrical shell structures.

[0012] By adopting a double-layer cylindrical shell to support the gear transmission system, and between the inner shell 3 and the outer double-layer shell 1, a reasonable number and rows of rubber material vibration isolators 2 are uniformly arranged to reduce vibration. The vibration isolator is mai...

Abstract

The invention discloses a cylindrical dual-layer shell structure with a vibration isolation system, and relates to the technical field of vibration isolation equipment. The cylindrical dual-layer shell structure comprises a casing and a vibration isolation device, wherein the casing comprises an outer-layer shell and an inner-layer shell, and the outer-layer shell and the inner-layer shell are connected through the vibration isolation device. According to the cylindrical dual-layer shell structure with the vibration isolation system, the vibration noise of the gearbox casing is reduced throughthe arrangement of the structure of the vibration isolation device 2 between the dual-layer shells; meanwhile, vibration isolation is conducted mainly aiming at gear excitation frequency, and the cylindrical dual-layer shell structure is significant in improving the concealment of naval vessels.

Description

Technical field: [0001] The invention relates to the technical field of vibration isolation equipment, in particular to a cylindrical double-layer shell structure with a vibration isolation system. Background technique: [0002] As the most threatening water and underwater weapons and equipment, the concealment is the main factor of its combat effectiveness. Due to the low energy loss of sound waves propagating underwater and the long range of action, acoustic stealth has become an important requirement for ship stealth. For the gearbox, its excitation frequency is single, which can be easily recognized by sonar. Therefore, vibration and noise isolation for gear transmission systems is particularly important. [0003] For aircraft compartments such as submarines with radially symmetrical planetary gear systems, the finite-length double-layer cylindrical shell structure is a typical structure. Between the existing double-layer cylindrical shells, a certain number of substructures...
