The production machines use fixed gearing and mechanical cams in history. The cams were used for specific stokes and cam switches were used for commissioning of technological process. This solution has disadvantages in lower production speed and no flexibility of production. This article summaries practical steps for machine modernization and highlight practical problems in modernization of older production machine. The electronic cam with direct linear drive was used for traversal motion with high peak acceleration. This paper discusses cam stoke curve design, redesign and fitting.展开更多
The principle of conjugate cam shedding mechanism forthe outside tappets with dual driving shafts is discussed,and its design conditions and parameters are studied,giving the results of practical calculations finally.
