摘要:	在透過創成磨齒加工齒輪的過程中，通常會在齒面產生規則且平行的齒面磨削紋理；而透過珩齒加工出的齒輪，其表面通常具有不規則的交錯紋理。為探討兩種磨紋對齒輪傳動性能之影響，本研究建立了一個混合流體動力润滑的數值模型，以模擬螺旋齒輪啮合時的润滑機制，並透過數值模擬軟體KissSoft計算不同具磨紋齒輪之傳動誤差、油膜溫度。結果表明具有交錯磨紋之齒輪，在齒面嚙合過程中，齒面間平均油膜厚度較大，且在高轉速下傳動誤差較小。因此相較於齒面具有平行磨紋之齒輪，具有交錯磨紋之齒輪整體傳動性能較佳。;During the gear manufacturing process using hobbing, regular and parallel tooth surface grinding patterns are typically formed. In contrast, gears produced through shaving exhibit surfaces with irregular and intersecting grinding patterns. To explore the impact of these two surface textures on gear transmission performance, this study established a numerical model based on mixed fluid hydrodynamic lubrication to simulate the lubrication mechanism during helical gear meshing. The numerical simulation software KissSoft was also employed to calculate the transmission errors for different gears with textured tooth surfaces. The results showed that gears with intersecting grinding patterns had larger average oil film thickness and lower average friction coefficient during the tooth meshing process, resulting in smaller transmission errors and lower oil film tempurature. Therefore, compared to gears with parallel grinding patterns on the tooth surface, gears with intersecting grinding patterns exhibited better overall transmission performance.
