Pull the1 inch manila rope inside the derrick and feed and reeve through the first crown sheave. 把一寸的棕绳穿过天车上的第一个滑轮,在井架内拉该棕绳。
Reeve the1 inch manila rope through the first crown sheave. 把棕绳穿过天车上的第一个滑轮。
When the casting is unloaded, side parting and core pulling are required as a circle dovetail groove is around the rope sheave. 绳轮铸件周缘有一圈梯形槽,铸件脱模时需进行侧向分型和抽芯。
Dynamic Modeling of Moving the Rope on a Sheave 曳引绳绕行运动动态模型
The operation principle and loading analysis of a synchronized four-sectioned telescopic mechanism using only one single stage hydraulic cylinder and a set of rope and sheave blocks are introduced in this article. Problems that should be noticed in the structural design work are also mentioned. 本文介绍了一种只用一个单级液压缸和一套钢绳滑轮系统的四节臂同步伸缩机构的原理和受力分析,并提示了结构设计中应注意的问题。
Mechanisms of fatigue failure of wire rope working with sheave are related to safety, reliability and economy of Wire rope transmission. 钢丝绳绕滑轮工作的疲劳损伤机理问题,关系到钢丝绳传动的安全性、可靠性和经济性。
Sensitive index α of influence of groove hardness of sheaves on fatigue life of a wire rope is proposed, which is a ratio of fatigue life of wire rope winding soft sheave group to one of hard sheave group. 引入了钢丝绳疲劳寿命对滑轮绳槽硬度的敏感指数α,将其定义为钢丝绳绕软滑轮组和绕硬滑轮组工作时疲劳寿命的比值。
