Vibration isolator inner sleeve and rubber spring assembly thereof
The invention provides a vibration isolator inner sleeve and a rubber spring assembly thereof, and belongs to the technical field of rail transit vibration and noise reduction. The rubber spring assembly consists of the following components in parts by weight: 100 parts of natural rubber, 4-10 parts of zinc oxide, 1-2 parts of a plasticizer, 1 part of protective wax, 1-20 parts of an antioxidant,3 parts of an anti-aging agent, 1-2 parts of an anti-reducing agent, 0.5-2 parts of an accelerant and the balance of S. The vibration isolator inner sleeve is characterized in that an inner sleeve base is composed of an inner bottom plate, a lower pipe and a spring lower blocking pipe, the spring lower blocking pipe of the inner sleeve base is of a hollow structure and is filled with solid dampingmaterials, and the solid damping materials are selected from two of butyl, polyvinyl chloride and epoxy resin and are mixed according to the weight part ratio of 1: 1. Compared with a traditional steel spring vibration isolator, the damping structure is good in integrity and good in energy absorption effect. The static rigidity of the rubber spring can be adjusted through a formula and the numberof cord fabric layers, and the flexibility is higher.
本发明保护一种隔振器内套筒及其橡胶弹簧组件，属于轨道交通减振降噪技术领域。本发明橡胶弹簧组件，由以下重量份配比的组分组成：天然橡胶100份，氧化锌4～10份，增塑剂1～2份，防护蜡1份，抗氧剂1～20份，防老化剂3份，抗还原剂1～2份，促进剂0.5～2份，余量为S。一种隔振器内套筒，内筒底座由内底板、下管和弹簧下挡管组成，内筒底座的弹簧下挡管为中空结构，内部填充有固体阻尼材料，固体阻尼材料选自丁基、聚氯乙烯和环氧树脂中的两种，按1:1重量份配比混合制成。相比于传统钢弹簧隔振器，本发明阻尼结构整体性好，吸能效果佳。橡胶弹簧可通过配方和帘子布层数来调节弹簧的静刚度，灵活性更强。
