引言维筒形转包具有结构简单可靠、倾转方便易于控制浇注速度、清渣修砌方便等优点,故目前在铸造生产中被广泛应用。但锥筒转包在设计计算中尚有些理论问题还未完善解决。例如还不能给一个明确的定轴公式,最大倾转力矩的求取也只能通过有限个点的计算来近似地解决。本文不准备系统地研究锥包设计,而仅仅就下面三个问题作比较深入的讨论。 Introduction The tube-shaped sub-package has the advantages of simple and reliable structure, easy tilting and easy control of the pouring speed, convenient slag removal and repair, so it is widely used in the casting production. However, there are still some theoretical problems in the design and calculation of cone tube subcontracting. For example, can not give a clear axis formula, the maximum torque can only be calculated by a finite number of points to be approximately resolved. This article is not intended to systematically study cone package design, but only on the following three issues for more in-depth discussion.
