Embodiment Construction

[0014] Referring to Figures 1 and 2, the present invention consists of five parts: a rubber capsule body 17, a disc flange 15, upper and lower cover plates 5, 18, high-performance sealing rings 9, 10, and upper and lower fillers 6, 4 in the rubber capsule body. .

[0015] The rubber capsule body 17 is vulcanized into an integral structure by the inner rubber layer 21, the outer rubber layer 19 and the cord skeleton layer 20. The skeleton layer is made of aramid fiber cord, and its strength is equivalent to that of steel wire, and about three times higher than that of nylon and polyester. Under the condition of the same structural size of the airbag, the rubber bladder body using aramid fiber cord is about three times higher than the rubber bladder body using ordinary nylon, polyester and other cords, and the bearing capacity is also about three times higher, so it can realize high pressure The large load ensures that the internal pressure of the strong vibration isolator reach...

Abstract

The present invention belongs to a high-pressure large-load air spring, in particular, it relates to a vibration isolator using compressed air whose pressure is greater than IMPa as elastic body. It is composed of the following several portions: rubber bag body with aramid fiber skeleton layer, cover plate, disked flange, sealing ring and filling material in the bag interior. Said invention also provides the concrete structure of above-mentioned every portion and the connection mode of all the above-mentioned portions. Said invention also provides the working principle of said high-pressure large-load air spring and its concrete operation method.

Description

technical field [0001] The invention relates to a vibration isolator using compressed air with a pressure higher than 1 MPa as an elastic body. Background technique [0002] Vibration is a ubiquitous phenomenon. Vibration can come from nature or from human production activities. In industrial fields such as ships, railway locomotives, and vehicles, the vibration of mechanical equipment will affect the comfort of the environment, and seriously cause damage to the equipment. In order to reduce the harm of vibration, vibration isolation is an effective method with little investment. Commonly used vibration isolators include rubber vibration isolators, metal vibration isolators (coil spring vibration isolators, butterfly spring vibration isolators, leaf spring vibration isolators, wire rope vibration Air spring. There are two types of air springs at home and abroad: capsule type and membrane type. The interface structure between the capsule body and the cover plate mainly inc...
