两步法设定粗纱成形齿轮的经验公式

The set up of an experience equation of roving forming gears by two-step method

粗纱成形齿轮设计参数是粗纱工艺中决定粗纱卷绕张力的一项重要参数,用"比例法"设计出粗纱成形齿轮时,经常需要多次调整才能保证粗纱张力的正常,给粗纱成形齿轮的精确设计带来了难度。文章给出了两步法精确设定常用粗纱机型成形齿轮的经验公式,并以A454型粗纱机为例,对经验公式的推导过程进行了介绍,为棉纺厂工程技术人员进行粗纱工艺设计提供了参考依据。

The design parameters of roving forming gears are one of important parameters in determing the roving winding tension in roving process. When designing the roving forming gears by use of ＂proportion method＂, it needs repeated readjustment to guarantee roving tension normal, which makes a precise design of roving forming gears difficult. In this article is worked out an experience equation of roving forming gears precisely set by two-step method, and take A454 roving frame as an example, the equation is detailed introduced, provided cotton mill technicians references for the roving process design.
