【摘要】：齒輪嚙合過(guò)程中能量損耗引起的齒廓形變改變了齒輪嚙合狀態(tài),基于Bloke閃溫理論,推導(dǎo)出了齒面接觸閃溫隨齒輪嚙合點(diǎn)位置變化的表達(dá)式,計(jì)算了齒面接觸閃溫引起的齒廓形變;通過(guò)Hertz接觸理論,推導(dǎo)出齒面接觸閃溫對(duì)嚙合剛度的影響表達(dá)式。對(duì)模型進(jìn)行研究,分析了摩擦因素隨嚙合點(diǎn)位置的變化規(guī)律,載荷、轉(zhuǎn)速對(duì)齒面最大接觸閃溫的影響,齒面接觸閃溫對(duì)齒廓形變和嚙合剛度的影響。仿真結(jié)果顯示,齒面接觸閃溫對(duì)輪齒嚙合剛度的影響較大,在非線性動(dòng)力學(xué)分析中應(yīng)予以考慮。
[Abstract]:The tooth profile deformation caused by the energy loss changes the gear meshing state. Based on the Bloke flash temperature theory, the expression of the tooth surface contact flash temperature with the gear meshing point position is derived. The tooth profile deformation caused by contact flash temperature on tooth surface is calculated. Through the Hertz contact theory, the influence expression of tooth surface contact flash temperature on meshing stiffness is deduced. The model is studied, and the variation law and load of friction factor with the position of meshing point are analyzed. The effect of the rotational speed on the maximum contact flash temperature of the tooth surface and the influence of the tooth surface contact flash temperature on the tooth profile deformation and meshing stiffness. The simulation results show that the tooth surface contact flash temperature has a great effect on the gear tooth meshing stiffness. It should be considered in nonlinear dynamic analysis.
