摘 要：论述了在普通车床上加工活塞杆的连接杆效率低下的原因以及难以保证尺寸精的原因。通过论证思考分析改进工艺流程，可以用数控车床代替普通车床加工连接杆。这样就省去在加工中心铣基准面的工序，但与此同时要改进夹具及其工装才能满足加工要求，改善后不仅提高了产能，而且大大节省了操作工的劳动量，满足了生产生产任务。

Abstract: This article discusses the lathe machining of the piston rod Connecting rod causes inefficient and difficult to guarantee the Size of the reasons. Reflection and analysis by demonstrating Improvement process, can be used instead of ordinary lathe CNC Lathe connecting rod. This eliminiates the need for datum in machining centers and milling processes. At the sametime to im-prove the productivity, and saves the operator the amount of Labor to meet production tasks.

摘 要：该文为解决加载试验机工作时引起磨损的严重问题，提出应用静压支承的原理来减小磨损。对静压支承液压系统采用压力跟踪控制方式,保证了静压支承具有足够的油膜刚度,提高了静压支承的承载能力。用压差减压阀在静压支承实现压力跟踪供油控制在国内尚属首次，虽然尚不成熟，但在此方面的探索是十分有益的，它可以为工业生产带来可观的经济效益。

Abstract: In order to solve the serious abrasion problem caused by loading test enginery, we introduce the static pressure supporting principle to deduce the abrasion. the pressure track and the differential pressure control mode have been applied in the hydraulic system of hydrostatic support. That not only guarantee the hydrostatic support has enough oil film rigidity, but also increase the capacity of lode. It is the first time to use pressure differential relief valve in the static pressure supporting. Although it’s immature yet, the explore to this field is very beneficial, because it can bring considerable economic benefit to industrial production.
