Problems solved by technology

Its structure is complicated and there are many parts. The connection between the disc flange and the air bag increases the weight of the air spring itself, and the filler on the cover occupies part of the volume of the closed space between the rubber bladder and the cover. The volume of the closed space is reduced, and the reduction of the volume of the closed space will affect the reduction of the natural frequency of the air spring and the improvement of the load capacity

Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1 to Figure 3 As shown, the naval airbag vibration isolator includes top plate 1, base 2 and middle airbag 3 from top to bottom. Into the closed space 5, the waist position of the middle airbag 3 is provided with a restraint belt 6 surrounding the middle airbag 3, and the restraint belt 6 is placed inside the capsule body of the middle airbag 3 and faces the said middle airbag 3. The outer side of the closed space 5 protrudes so that it does not occupy the inner space of the closed space 5 and ensures the maximum volume of the closed space 5. A buffer pad 7 is installed on the base 2, and the buffer pad 7 is placed on the Inside the enclosed space 5, the horizontal distance and the vertical distance from the buffer pad 7 to the top plate 1 are L1 and L2 respectively, and the values ​​of L1 and L2 both range from 1 mm to 20 m...

Abstract

A marine airbag vibration isolator comprises a top plate, a base and a middle airbag from top to bottom, wherein the top plate, the base and the middle airbag are in sealed match to form a sealed space; an air inlet pipe penetrates through the base to stretch into the sealed space; the marine airbag vibration isolator is characterized in that a restraint strap surrounding a middle airbag is arranged at the waist position of the middle airbag; the restraint strap is located in a bag body of the middle airbag and protrudes out of the outer side of the sealed space; a buffering cushion is arranged on the base; the buffering cushion is arranged in the sealed space; the horizontal distance and the vertical distance from the buffering cushion to the top plate are L1 and L2; the value ranges of the L1 and the L2 are 1mm-20mm. The marine airbag vibration isolator has a simple structure and light weight, low self-vibration frequency and high bearing capability.

Description

technical field [0001] The invention relates to the technical field of vibration isolators, in particular to a low-frequency airbag vibration isolator applied to vibration and noise reduction of naval equipment. Background technique [0002] Airbag vibration isolators are also called air springs. Compared with metal spring vibration isolators and rubber-metal vibration isolators, airbag vibration isolators use compressed gas as the working medium, have high flexibility, low natural vibration frequency, and are highly controllable. With the advantages of large standard load, etc., it is widely used in air suspension systems such as railway vehicles and automobiles. Noise reduction is an important means to improve the concealment of ships. The airbag vibration isolator has a very low natural frequency and excellent vibration isolation performance, which can significantly reduce the structural noise of the ship. Therefore, the use of airbag vibration isolators to reduce the me...
