【摘要】：針對(duì)傳統(tǒng)采煤機(jī)滾筒恒速截割時(shí)工況適應(yīng)性差的特點(diǎn),提出一種采煤機(jī)滾筒轉(zhuǎn)速可調(diào)的新型截割傳動(dòng)系統(tǒng)。為了解該截割傳動(dòng)系統(tǒng)的性能,以系統(tǒng)中非同軸傳動(dòng)的差動(dòng)2K-H行星輪系為研究對(duì)象,采用集中質(zhì)量法建立其平移-扭轉(zhuǎn)耦合動(dòng)力學(xué)模型。對(duì)輪系固有特性的分析表明,非同軸傳動(dòng)行星輪系不存在經(jīng)典的扭轉(zhuǎn)振動(dòng)與平移振動(dòng)模式,但仍存在行星輪振動(dòng)模式;支撐剛度對(duì)系統(tǒng)的低階固有頻率影響較大,而嚙合剛度主要影響系統(tǒng)的高階固有頻率;外嚙合齒輪副嚙合剛度分段影響非同軸傳動(dòng)行星輪系的固有頻率。推導(dǎo)出2K-H行星輪系嚙合頻率的通用表達(dá)式,表明其嚙合頻率正比于齒圈和太陽(yáng)輪的轉(zhuǎn)速差。分析結(jié)果可用于指導(dǎo)該新型采煤機(jī)截割傳動(dòng)系統(tǒng)的設(shè)計(jì),并為制定滾筒調(diào)速范圍提供參考。
[Abstract]:In order to understand the performance of the cutting transmission system , the differential 2K - H planetary gear train with non - coaxial transmission is used as the research object in order to understand the performance of the cutting transmission system . The analysis of the inherent characteristics of the wheel system shows that the meshing frequency of the non - coaxial transmission planetary gear system is proportional to the difference of the rotation speed of the ring gear and the sun gear . The analysis result can be used to guide the design of the cutting transmission system of the novel coal mining machine and provide a reference for the development of the drum speed regulation range .

【正文快照】： 采煤機(jī)是實(shí)現(xiàn)煤礦綜采工作的關(guān)鍵設(shè)備[1-2],在復(fù)雜截割載荷作用下[3],其傳動(dòng)系統(tǒng)的可靠性與控制性能決定了礦企是否能安全、高效生產(chǎn)。對(duì)采煤機(jī)滾筒轉(zhuǎn)速與牽引速度之間的關(guān)系進(jìn)行合理匹配,可以實(shí)現(xiàn)采煤效率、塊煤率、截割比能耗三者間的最優(yōu)控制[4-5];同時(shí),變截割轉(zhuǎn)速能夠更好，
