The Study On The Silicone Oil Clutch And The Essential Techniques Of It

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.
