TSXCAY22材料彈性力學(xué)使得齒輪組嚙合時,主、被動齒輪可簡化為圍繞軸心線旋轉(zhuǎn)的懸臂梁模型[1],在承受負(fù)荷時會產(chǎn)生彎曲變形, 而且齒面接觸區(qū)域存在彈性形變。另外,齒輪制造加工誤差、殼體加工誤差、裝配等各種誤差的客觀影響, 造成齒輪實際嚙合點與理論嚙合區(qū)域存在偏移, 產(chǎn)生了嚙合沖擊激勵。為了減少齒輪嚙合時產(chǎn)生的誤差,在設(shè)計早期應(yīng)該對齒輪的NVH做仿真預(yù)測。齒形修形是優(yōu)化齒輪接觸位置和應(yīng)力大小的有效方法,微觀修形可以針對嚙合的一對齒輪,也可只做單齒輪修形優(yōu)化,在工程實踐中通常更多采取對單一齒輪修形,其具備較高的生產(chǎn)效率和較低的生產(chǎn)成本。通常齒廓修形的關(guān)鍵影響因子有輪廓修形、寬度、齒根和齒頂修形,其中齒根修形參數(shù)的確定,需要兼顧修形參數(shù)的選擇同時考慮齒軸的系數(shù),避免齒根修形過大引起齒輪齒根彎曲強度的降低。圖4展示了齒廓修形的常規(guī)形式,包括左右端直線修形、螺旋線修形和鼓性修形。具體齒廓修形的方案選擇,需綜合考慮輸入負(fù)荷激勵的大小、傳遞路徑的剛度及易加工等因素,結(jié)合NVH仿真工具優(yōu)選齒廓修形方案。
