起毛机主传动结构设计
摘要
本课题是在目前使用较广泛的国产M301起毛机由单台电机作拖动动力源,各传动部分由机械联接协同运行。该类起毛机工作稳定,维修简单,但产量低,改变工艺困难,难以获得高质量的起绒效果。
通过本次设计,我对传动部分的全过程有了清醒而直观的认识,了解了起毛机的工作原理,对轴、链轮、带轮等主要零件的设计及精度的确定具备了一定的经验知识,能够正确地选取标准零件的结构及尺寸。由于知识及实践经验的缺乏,在设计过程中,尚存在许多不足之处,尤其是减速器的体积、效果等方面,有待以后的工作、学习中改进。

The Structure Design of Main Transmission of Teasing Machine
Abstract
The problem is to move the driving force source in using broader domestic M301 wool card to drag from Shan electric motor work at present , every drive part cooperates and work from machinery linkup. Owe a kind wool card job stability , keep the simplicity, but output in repair low , change handicraft difficulty, be difficult to gain height mass raising effect.
Through the design of teasing machine, the overall processes of the transmission system have been clearly and directly known. Meanwhile, I acquaint with operating principle of teasing machine, the main parts of which such as axis, chain pulley and band pulley have been acquired lots of experience about their design and precision. Also I have learnt to select the structure and sizes of standard parts. However, because of lack of practical experience, I discover lots of deficiencies during the design of bulk and results of the retarder. Therefore, I will try to do better in the future in my work.
Key words:teasing machine; structure design; main transmission design; retarder design

2 总体方案论证
本课题研究的对象为:起毛机主传动结构设计,主要完成由电动机到针辊的转动。设计的重点与难点是:如何确保针辊转动的连续、快速与均匀,包括公转和自转,所以电动机输出的转速与各级传动的转速都应该考虑好。每个轮与轴的转速都不同,所以每一步确定的转速都要合理,以确保达到设计要求。
2.1 已知技术参数
紧边的张紧力 F = 7500N
松边的张紧力 F = 200N
针辊总直径 D = 1.3 m
织物通过针辊的速度 20—60 m/min
