一、往复式发动机的机械力学 1.筒形活塞与十字头式活塞 由图1来看,大概筒形活塞形状简单,工作原理易于理解,然而希望设计者不要忘记十字头式活塞的作用原理。 由于活塞体代替了十字头导块,则可认为活塞是一个园柱形的十字头。因此,筒形活塞润滑很重要,如设计不当,将会因活塞 First, the mechanical reciprocating engine 1. Cylinder piston and crosshead piston Figure 1, probably cylindrical piston shape is simple, easy to understand the working principle, but hope designers do not forget the principle of crosshead piston. Since the piston body replaces the crosshead guide, the piston can be considered as a cylindrical crosshead. Therefore, cylindrical piston lubrication is very important, if not properly designed, will be due to the piston
