由于立铣头结构上的特性,一般多采用迷宫密封(如图1)来防止漏油。但采用这种密封,润滑油仍会从两相对转动件配合间隙处泄漏出来,所以只能把润滑油的泄漏量限止在最低限度內而不能防止泄漏。我厂修理工人翻阅了国內外各种密封资料,参考国外机床的密封结构,在立铣头上试验采用端面密封。通过六台铣床的改装试验,基本上消除了立铣头漏
Due to the characteristics of milling head structure, the general use of labyrinth seal (Figure 1) to prevent oil leakage. However, with this seal, the lubricating oil will still leak from the clearance between the two opposite rotating parts, so that the lubricating oil leakage can only be kept to a minimum and can not be prevented from leaking. Our factory workers through a variety of domestic and foreign seal information, refer to the sealing structure of foreign machine tools, test the head end of the face seal. Through six milling machine modification test, basically eliminating the head milling leakage
