【摘要】 随着液体粘性传动技术的发展，越来越多的液体粘性传动装置在很多领域获得了应用，本文在分析现有几种液体粘性传动装置的基础上，从理论上构想设计出一种新的液体粘性传动装置—硅油离合器，并对该装置的结构进行设计，对影响其性能的技术进行分析探讨。全文共分为五章。第一章为绪论，着重分析了本课题的背景和意义，包括液体粘性传动技术的原理、特点和国内外对该技术的研究现状，以及论文工作的安排。第二章在阅读大量文献的基础上，对目前几个领域获得广泛应用的液体粘性装置的结构、工作原理、粘性剪切转矩的计算进行了总结，给出了硅油离合器的结构形式、工作原理、以及其传递剪切转矩的计算、传递额定转矩的计算，并对离心块工作过程中的受力进行了分析探讨。第三章对硅油离合器进行了设计与校核，对所有的构成部件的结构、尺寸根据设计要求和传递转矩和功率加以设计计算，对需要校核部分进行校核以满足结构强度的要求。另外，设计中密封件采用了新的密封材料—氟胶密封，选用了低粘度的硅油。确定连接螺钉、回位弹簧、以及滚动轴承的型号，绘制了零件图。第四章采用Pro／ENGINEER三维实体设计软件对硅油离合器各构成部件的三维模型进行了建模，并进行了虚拟装配，生成二维工程图。第五章对硅油离合器设计中几个关键影响因素进行了研究与探讨，包括硅油离合器工作介质(硅油／空气)的特性；实现粘性剪切传动对摩擦副的要求、摩擦副材料的选择，并对几种摩擦材料进行对比和研究；离合器工作过程中内部硅油的流动方式、温度和压力特性，并建立了离合器的传热模型。更多还原

【Abstract】 Along with the liquid viscous transmission technology development, more and moreliquid viscous transmission devices has obtained the application in many fields, this article inthe analysis of existing several kinds of liquid viscous transmission devices foundation,theoretically devises the design of a kind of new liquid viscous transmission device-siliconeoil clutch, and carries on the design to this clutch’s structure, studies the factors that affect itsperformance.The full text altogether divides into five chapters. First chapter is the introduction,emphatically analyzes this topic background and the significance, including liquid viscoustransmission technology principle, characteristic and domestic and foreign present situation tothis technical research, as well as paper work arrangement. Second chapter in the readingmassive literature foundation, summarizes the structure, the working principle, the shearingtorque calculation of liquid viscous devices which are widespread applied to several fields atpresent. The silicone oil clutch structure, the principle of working, the calculation of shearingtorque and rated torque are put forward, further, the forces that act on the centrifugal block inworking process are discussed. Third chapter carries on the design and the correction to thesilicone oil clutch, designs the structure of all constitution parts under the request of designand transmission, examines the parts which need examination to satisfy the structuralstrength request. Moreover, in the design the new seal material-fluorine rubber seal will beused and the low viscosity silicone oil be selected. The determination of screw joint, washer,compressible spring, as well as the rolling bearing is carded on and the detail drawing isdrawn up. Fourth chapter uses Pro/ENGINEER three dimensional entity design softwarerespectively to constitute three-dimensional model of parts of the silicone oil clutch, finallycarries on the virtual assembly of clutch, produces two-dimensional engineering drawing.Fifth chapter conducts several essential factors which directly influence the success of thesilicone oil clutch design, including silicone oil clutch actuating medium (siliconeoil/air)characteristic, the request to friction coupling to realize the shearing transmission, thechoice of friction coupling material. In the article carries on the contrast and the research to several kind of friction materials. The mobile way and temperature change of the internalsilicone oil are studied in the clutch working process, meanwhile the reason elevate theinternal silicone oil’s pressure and the characteristic of internal silicone oil are discussed. Inthe end the heat transfer model of clutch is established.更多还原
