液压挖掘机自五十年代问世以来,由于其结构简单、重量轻、操作灵便、挖掘力大而受到普遍欢迎。其发展甚速,斗容日亦增大,目前国外已有斗容为8～15.3立方米的大型液压挖掘机。五十年代末,我国开始研制液压挖掘机,随着液压元件质量的提高,近几年来已有较快地发展。目前斗容已达1.6～2.5立方米。提高大斗容挖掘机性能,是设计中应当重视的问题。当前,液压挖掘机机构尺寸的确定方法尚不够合理,甚至带有某些盲目性,因此不能很好地突出液压挖掘机的一些优点。本文将对液压正铲挖掘机机构尺寸参数的确定方法加以探讨。文中所述方法与原理对于液压反铲挖掘机
Since the hydraulic excavator was introduced in the fifties, it has been generally welcomed because of its simple structure, light weight, convenient operation, and large digging force. Its development is very rapid, and its capacity for warfare has also increased. At present, there are large-scale hydraulic excavators with a bucket capacity of 8 to 15.3 cubic meters. In the late 1950s, China began to develop hydraulic excavators. With the improvement of the quality of hydraulic components, it has developed rapidly in recent years. The current capacity has reached 1.6 to 2.5 cubic meters. Improving the performance of large bucket capacity excavators is an issue that should be emphasized in the design. At present, the method of determining the size of the hydraulic excavator mechanism is not yet reasonable, even with some blindness, so it can not highlight some of the advantages of the hydraulic excavator. This article will discuss the method of determining the size parameters of the hydraulic shovel shovel mechanism. The methods and principles described in this paper apply to hydraulic backhoes
