    摘要:

    為揭示雙環(huán)減速器系統(tǒng)中各零部件的真實(shí)受力情況,，對完全平衡,、非180°相位差的雙環(huán)減速器進(jìn)行了深入研究。受力分析中計(jì)入了諸多影響因素,，如高速軸,、環(huán)板,、齒輪副、軸承的彈性變形及支承軸的附加轉(zhuǎn)角,?；诹?位移混合法構(gòu)造了相應(yīng)的變形協(xié)調(diào)條件，建立了該類過約束機(jī)構(gòu)的彈性動(dòng)態(tài)靜力學(xué)方程,。雙環(huán)減速器中行星軸承的彈性變形最大,，高速軸次之,；環(huán)板的拉壓、彎曲變形接近,，不可忽略,。

    Abstract:

    The double-ring gear reducer (DRGR) is a novel planetary gearing with small tooth-number difference. It has apparent advantages over common gear reducers such as large transmission ratio, high loading capacity, compact volume, low fabricating cost and wide adaptability. To obtain actual loading state of the components, a DRGR featuring a phase-angle difference of non-180 degrees and complete equilibrium has been investigated in details. Key influences were taken into account including the elasticity of high-speed shafts, gear-couplers, meshing teeth and bearings as well as additional rotation angle of the supporting shaft. The compatibility conditions of elastic deformations were derived by means of the so-called force-displacement hybrid method. Finally, the elasto-quasi-static equation of the over-constrained mechanism was developed.
