摘要
 液體粘性調(diào)速離合器屬于液體粘性傳動，這是一門新興的學(xué)科。，它是利用液體的粘性和油膜剪切來傳遞動力的。其基本原理是牛頓內(nèi)摩擦定律：兩平行的平板間充滿粘性的液體，形成一定厚度的油。當(dāng)兩平板作相對運(yùn)動時(shí)，其間的油膜受到剪切作用，動力由主動盤傳向被動盤。油膜所傳遞的切應(yīng)力大小與液體的動力粘度成正比，與兩平板的相對速度成正比，與油膜厚度成反比。液體粘性調(diào)速離合器就是根據(jù)上述工作原理設(shè)計(jì)而成的。液體粘性調(diào)速離合器通過調(diào)節(jié)油膜厚度來改變所傳遞動力的大小，從而達(dá)到無級調(diào)速的目的，可獲得無轉(zhuǎn)速差高效率的直接傳動，理論上此時(shí)無功率損失，是一種新型的軟啟動裝置；而且液體粘性調(diào)速離合器可通過控制油壓力的大小來控制傳遞轉(zhuǎn)矩，可以自動限制傳遞的轉(zhuǎn)矩，因而對傳動系統(tǒng)起到保護(hù)作用。論文論述了液體粘性調(diào)速離合器自身特點(diǎn)，比較了與其它變速器的差異，分析了其國內(nèi)外的研究現(xiàn)狀；包含了該類離合器的整體方案設(shè)計(jì)和主機(jī)主動部分一些零件的設(shè)計(jì)、計(jì)算及校核。

ABSTRACT   
 Hydro-viscous speed-adjusting clutch belongs to the liquid coherent transmission, this is an emerging discipline. It is transmits the power using the liquid coherency and lubricant film cutting. Its basic principle is the Newton internal friction law: Between two parallel plates fills the coherent liquid, forms certain thickness the oil. When two plates make the relative motion, during lubricant film receives the shear action, the power passes on by the driving disc to by the shifting plate. The lubricant film transmits the shear stress size and the liquid dynamic viscosity is proportional, is proportional with two plate relative velocities, is in reverse proportion with the lubricant film thickness. Hydro-viscous speed-adjusting clutch is becomes according to the above principle of work design. Hydro viscous speed-adjusting clutch changes through the adjustment lubricant film thickness transmits the power the size, thus achieved the stepless speed regulation the goal, Poor access to efficient without rotational speed direct transmission, in theory at this time without power loss is a new type of soft start device; And liquid became governor through control oil pressure starts to control the size of the transmission of torque and can limit transmission of torque automatically, which play a protective role of drive train system. Papers discussed Hydro-viscous speed-adjusting clutch its own characteristics compared with other clutch differences, the study analyzed the current status of its domestic and foreign; Contain such weak overall program design and some parts of the mainframe to the design, calculation and verification.
 Key words:  hydro-viscous drive；hydro-viscous speed-adjusting clutch；stepless timing； soft-start
