1、Avoid the application of more than the maximum compression, the pressure will cause damage, close to the use of dense long, so that the hardware spring line gradually dense, so the hardware spring of the fixed number of high will cause the load curve with the growth of high, this time will make the spring break, so the use can not exceed 300,000 times.
2, avoid gaps, because there is a gap caused by the vibration of the hardware spring up and down the spring distortion, if the pre-pressure, hardware spring will be more stable.
3、Do not use the hardware spring horizontally, if the hardware spring is used horizontally, it will cause the guide pin and the spring to wear and may break.
4, to use the inside diameter guide pin or outside diameter guide devices, if used in the case of hardware spring guide, it is very easy to cause the bottom of the spring and the body of the distortion, the distortion of the local high pressure is an important cause of spring fracture.
5、If the parallelism of the assembly surface is not good, the spring will be twisted, and the high pressure will break, and if the parallelism is not good, the spring will be twisted and the spring will break in more than 300,000 times. It is not possible to improve the parallelism of the assembly surface under the condition that it is used for more than 300,000 times.
6、When the clearance between the pin and the guide is very small, this will cause the inner diameter of the collision wear, wear is an important cause of hardware spring fracture, on the contrary, such as between too large will easily cause hardware spring twist fracture, the best between the inner diameter of the spring - 1.0mm or so. For springs with long free lengths (free length/external diameter more than 4), please use a segment step or guide pin to avoid collision between the spring body and the guide pin when the spring body is twisted.
