在现代高参数轧钢机,如:连续轧机,多辊轧机,型钢轧机等,人字齿轮机是不可缺少的主要设备。关于人字齿轮机装配式机架的设计与计算,已有专文介绍。本文现就开启式机架的计算进行探讨。开启式机架有两种型式,即抛物线底机架(图1)和平底机架(图5)。本文公式代号: X——水平分力; J_2——立柱之惯性矩 C_1——机架下面X力与立柱根部连线(在平机架时则为下横梁中和线)间之距离; l_2——立柱中和线长度;
In the modern high-parameter rolling mills, such as: continuous rolling mill, multi-roll mills, steel mills, etc., Herringbone gear is an indispensable main equipment. About the word gear assembly rack design and calculation, has been introduced. This article is on open rack calculation to explore. There are two types of open racks, the parabolic base rack (Figure 1) and the flat rack (Figure 5). The formula code of this article: X - horizontal force component; J_2 - moment of inertia of the column C_1 - the distance between the X force under the frame and the root of the column (the neutralization line of the lower beam when in the horizontal frame); l_2 - Column neutralization line length;
