根据椭圆接触理论,得出碟形砂轮磨削面齿轮时的基本磨削参数,并建立了有限元模型,采用矩形分布热源对面齿轮磨削热进行模拟,得出其磨削温度场。由该模拟结果得出碟形砂轮磨削时的温度变化规律为:沿齿长方向近心端和沿齿高方向相对接近齿根区域时,面齿轮的磨削温度逐渐升高。同时,利用红外测温仪对实际机齿轮磨削温度进行测量,将所得结果与有限元分析结果进行对比,发现各磨削点的误差分析结果均在5%~20%,并且温度越高,误差越小,从而验证了椭圆接触理论在面齿轮磨削热研究中的可行性。
根據橢圓接觸理論,得齣碟形砂輪磨削麵齒輪時的基本磨削參數,併建立瞭有限元模型,採用矩形分佈熱源對麵齒輪磨削熱進行模擬,得齣其磨削溫度場。由該模擬結果得齣碟形砂輪磨削時的溫度變化規律為:沿齒長方嚮近心耑和沿齒高方嚮相對接近齒根區域時,麵齒輪的磨削溫度逐漸升高。同時,利用紅外測溫儀對實際機齒輪磨削溫度進行測量,將所得結果與有限元分析結果進行對比,髮現各磨削點的誤差分析結果均在5%~20%,併且溫度越高,誤差越小,從而驗證瞭橢圓接觸理論在麵齒輪磨削熱研究中的可行性。

According to the elliptical contact theory , obtained disc wheel basic grinding parameters of gear grinding surface and established finite element model, and using the rectangular distribution of heat for the gear grinding thermal simulation, obtained the grinding temperature field. The results showed that the temperature variation law of the saucer wheel grinding is : along the direction of tooth proximal near heart and along the direction of tooth height relatively close to the root area, the grinding temperature gradually increased. Meanwhile using infrared thermometer to measure actual grinding temperature, compared the measured temperatures with the finite elemental analysis results, found that the error analysis results of all the grinding points were between 20% and 5%, and the higher the temperature, the smaller the error was, verified the feasibility of the ellipse contact theory in the surface gear grinding thermal research.
