Abstract

The invention discloses a high-pressure sealed nitrogen spring. A nitrogen cylinder component filled with nitrogen is placed in oil in an oil cylinder component. The oil cylinder component comprises an oil cylinder cavity plunger and an oil cylinder body, a space between the oil cylinder cavity plunger and a guide sleeve is sealed, the oil cylinder cavity plunger is movably connected with the guide sleeve, a space between the guide sleeve and the oil cylinder body is sealed, and the guide sleeve is fixedly connected with the oil cylinder body. The nitrogen cylinder component comprises a nitrogen cylinder end cover, a nitrogen cylinder body and a nitrogen cavity plunger, wherein the lower end of the nitrogen cavity plunger is placed on the bottom face of the oil cylinder body, the upper end of the nitrogen cavity plunger is inserted into an inner cavity of the nitrogen cylinder body, and the nitrogen cylinder end cover is arranged at the top of the nitrogen cylinder body. By the adoption of the structure that the nitrogen cylinder component is sealed by oil contained in the oil cylinder component, sealing of the nitrogen spring is effectively achieved under high temperature and high pressure, structural design is simple and reasonable, manufacturing cost is low, a nitrogen system is controlled stably, and temperature change is controlled stably; meanwhile, due to the lubricating function of the oil, the oil cylinder component and the nitrogen cylinder component have very good lubricity.

Description

technical field [0001] The invention relates to the technical field of elastic elements, in particular to a high-pressure sealed nitrogen gas spring. Background technique [0002] With the continuous advancement of science and technology, the requirements for elastic elements in the industrial field are getting higher and higher, which not only require elastic elements to meet various needs of mechanical structures, but also require miniaturization and high performance of elastic elements. Conventional elastic elements used in the prior art, such as springs, elastic rubber, and air cushions, etc., the elastic force produced increases proportionally with the increase in compression and cannot maintain a constant pressure during the work process, and the telescopic stroke is small, and many The process requires constant elastic changes. Conventional elastic elements have a great influence and limitation on the process design requirements, and cannot meet the process requiremen...
