避免弹簧使用不当有什么办法
文章来源:http://www.sdzbthc.com/ 发布时间:2021-08-18 浏览次数:
1、避免超过压缩量的应用,压力的产生进而会造成折损,接近密著长之使用,这样会使弹簧线部逐渐的密著,所以弹簧的定数变高会造成荷重曲线随着而生高,这时候会使弹簧断裂,所以使用不能超过30万回。
  
  1. Avoid the application that exceeds the compression amount. The generation of pressure will cause damage and close to the use of tight length, which will gradually close the spring line. Therefore, the higher the fixed number of the spring will cause the higher the load curve. At this time, the spring will break, so the use can not exceed 300000 cycles.
  
  2、因有间隙造成了弹簧上下的震动导致弹簧的扭曲,如果预压的时候,弹簧会比较的稳定。
  
  2. The up and down vibration of the spring is caused by the gap, resulting in the distortion of the spring. If the spring is preloaded, it will be more stable.
  
 
  3、弹簧如果横置使用的时候,这时会造成导销和弹簧磨损而且可能会断裂。
  
  3. If the spring is used horizontally, the guide pin and spring will be worn and may break.
  
  4、如果在弹簧导引的情况下使用,这时非常容易造成弹簧底部和本体的扭曲,其扭曲部的局部高压力是导致弹簧断裂的重要原因,所以要使用内径导销或者外径引等装置。
  
  4. If it is used under the guidance of the spring, it is very easy to cause the distortion of the bottom and body of the spring. The local high pressure of the twisted part is an important reason for the fracture of the spring. Therefore, devices such as inner diameter guide pin or outer diameter guide pin should be used.
  
  5、装配面之平行度不好时会造成弹簧扭曲,局部产生高压力断裂,及平行度不好之场合造成弹簧扭曲与超过30万回使用造成弹簧断裂。不能够在超过30万回使用的条件下改善装配面的平行度。
  
  5. When the parallelism of the assembly surface is not good, the spring will be distorted, and high pressure fracture will occur locally. When the parallelism is not good, the spring will be distorted and more than 300000 cycles will be used, resulting in spring fracture. The parallelism of the assembly surface cannot be improved under the condition of more than 300000 reuse.
  
  6、与导销之间间隙非常小的时候,这时会造成内径之碰撞磨耗,磨耗部就是造成弹簧断裂的重要原因,相反如间太大就会容易造成弹簧扭曲断裂,合适弹簧内径-1.0mm左右。及自由长较长的弹簧(自由长/外径大于4以上)请用段阶或者导销,需要避免弹簧体扭曲时和导销之间的碰撞。
  
  6. When the clearance between the spring and the guide pin is very small, the impact wear of the inner diameter will be caused. The wear part is an important reason for the spring fracture. On the contrary, if the clearance is too large, it will easily cause the spring to twist and fracture. The appropriate inner diameter of the spring is about -1.0mm. For springs with long free length (free length / outer diameter greater than 4), please use step or guide pin to avoid collision with the guide pin when the spring body is twisted
