[分享]液壓缸受力分析二

樓主#
更多 發布于：2017-12-18 08:31
隨著活塞桿行程的變化，液壓缸導向副受到的作用力F也隨之變化。當F達到一定程度——超過導向副支承環的支承能力時，支承環便會龜縮（我們權且這樣叫它）到支承環槽子里去，此時，導向副金屬面與金屬面接觸、摩擦、拉傷、泄漏等等現象就發生。
溫度的升高，使支承環的彈性模量E急劇減小，因此，液壓介質高溫會加速支承環的龜縮，即加速液壓缸導向副拉傷現象的提前到來。國產挖掘機液壓缸容易拉傷就是很好的例證，這也是令各仿制生產廠家最頭疼的問題。
當支承環發生龜縮時，液壓缸兩大摩擦副的運動間隙，已經嚴重超出我們設計要求，在非設計的軌道上運行，豈能不拉傷。
解決的辦法——采用《液壓自動對中柱塞副專利》技術。
