摘要
本文提出了，用对心曲柄滑块机构和其它机构串联组成八杆机构，该机构能成型活塞裙部等截面曲线。当把该八杆机构变成九杆机构时，该九杆机构可以成型活塞变截面曲线。本文还分析了机构切削工件误差。
In this paper,crankslip mechanism linked with other mechanism becomes a new mechanism that is a bar mechanism.Then fixed section curve of the piston skit can be formed by the 8 bar mechanism. When the 8 bar mechanism turn into 9 bar mechanism, the variable section curve of the piston skirt can be formed by the 9 bar mechanism. On the other hand,we give the error of the 9 bar mechanism when the workpiece is Cutting.
