本文以液压起落钻架机构为例,把机构的设计同液压传动系统的设计联系起来,以确定液压系统合理的工作压力、提高传动效率、降低成本为目标,提出按油缸双向最大工作压力相等的原则来设计双作用摆动油缸机构。文中介绍了根据此原则,分别按给定的某一构件的长度、下限位置传动角、初始安装角、油缸作用力臂最大的条件设计的方法。通过实例计算表明,此设计方法具有明显的经济效益。最后讨论了该设计方法的适用条件。 In this paper, taking the hydraulic lifting and rigging mechanism as an example, the design of the mechanism is linked with the design of the hydraulic transmission system to determine the reasonable working pressure of the hydraulic system, increase the transmission efficiency, and reduce the cost. It is proposed that the two-way maximum working pressure of the hydraulic cylinder is equal. The principle is to design a double-acting swing cylinder mechanism. This article describes the design method according to this principle, according to the length of a given component, the transmission angle of the lower limit position, the initial installation angle, and the maximum conditions of the force arm of the cylinder. The example calculation shows that this design method has obvious economic benefits. Finally, the applicable conditions of this design method are discussed.
