As a key elastic component in mechanical and high-speed operating equipment, the inclined coil spring faces various complex working conditions in practical applications. Common failure causes include fatigue fracture, plastic deformation, corrosion damage, installation deviation, and material defects. Under long-term high-frequency alternating loads, springs are prone to microcracks and gradually propagate, leading to fatigue fracture. Exceeding the expected axial or radial load in the design will cause plastic deformation of the spring, resulting in the loss of its expected elastic performance.

If the working environment is accompanied by humidity, acidity, alkalinity, or other corrosive media, it will accelerate the corrosion of the inclined coil spring surface and weaken its load-bearing capacity. Axial misalignment, excessive compression of turns, or uneven positioning during installation can cause local stress concentration and premature damage. If there are impurities, pores, uneven structure and other problems in the material selection stage, the spring is also prone to fracture or performance degradation during use. To extend the service life of the inclined coil spring, it is necessary to select materials that meet the standards based on the usage environment, and fully consider the load, vibration, and space conditions during the design phase to ensure standardized assembly processes. At the same time, regular maintenance and cleaning should be carried out to promptly detect and replace faulty components.
