Spiral cooling is adopted in the structure, the contact face is larger and more uniform, the cooling effect is better, machining is easy, machining feasibility is high, the structure is firm and durable, the temperature of the nitrogen spring is controlled, and therefore the risk of high temperature is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen springs, in particular to a spiral nitrogen spring water cooling structure. Background Art

[0002] Nitrogen spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It has small size, large elastic force, long stroke, stable operation, precision manufacturing, long service life, flat elastic force curve, and no need for pre-tightening. Nitrogen spring has a wide range of uses and its appearance meets the requirements of the times.

In high-temperature environments, the seals of nitrogen springs are prone to deformation and damage, leading to gas leakage. Precision parts will also produce thermal expansion reactions, which seriously affect the service life of nitrogen springs. Utility Model Content
