摘 要 卷?yè)P(yáng)機(jī)，是用卷筒纏繞鋼絲繩以提升或牽引重物的輕小型起重設(shè)備。本設(shè)計(jì)以零件疲勞理論和線性累積損傷假說(shuō)為理論基礎(chǔ)，運(yùn)用靜力學(xué)的普遍原理，分析和解決了絞車(chē)運(yùn)動(dòng)過(guò)程中的一些受力和運(yùn)動(dòng)問(wèn)題，力求最優(yōu)化和最可靠設(shè)計(jì)絞車(chē)減速器和卷筒。 本文主要介紹了卷?yè)P(yáng)機(jī)的發(fā)展歷史，用途，組成及工作原理；卷?yè)P(yáng)機(jī)的工作特點(diǎn)；設(shè)計(jì)的一般步驟；使用中存在的問(wèn)題及改進(jìn)措施。在本次卷?yè)P(yáng)機(jī)的設(shè)計(jì)過(guò)程中，著重對(duì)減速器、卷筒進(jìn)行了分析和設(shè)計(jì)。對(duì)重要的部件進(jìn)行了受力分析、強(qiáng)度的校核，根據(jù)其常見(jiàn)失效形式、影響因素及基本設(shè)計(jì)要求，給出了重要部件的受力分析、強(qiáng)度和剛度的設(shè)計(jì)方法。 關(guān)鍵詞：卷?yè)P(yáng)機(jī)； 減速器； 軸； 齒輪 ABSTRACT The winch, is promotes or the hauling heavy item light small hoisting equipment with the reel winding steel wire. This design take the components fatigue theory and the linearity cumulative damage hypothesis as the rationale, the utilization statics general principle, analyzed and has solved in winch rate process some stress and the movement question, made every effort the optimization and the most reliable design winch reduction gear and the reel. In the most universal winch type of drive and in the structure foundation, utilizes the position sensing and the water level sensing technology, uses the PLC control, realized the traction winch to promote and to release the pump house according to the water level the automatic control and the hand control. This article mainly introduced winch's historical development, the use, the composition and the principle of work; Traction winch's operating feature; Design general step; In the use exists question and corrective measure. In this traction winch's design process, to the reduction gear, the reel has carried on the analysis and the design emphatically. Has carried on the stress analysis, the intensity examination to the important part, according to its common failure mode, the influencing factor and the basic design request, has given the important part's stress analysis, the intensity and the rigidity design method.
