【摘要】：針對(duì)擺線齒錐齒輪刀盤參數(shù)的選取,研究了刀盤半徑修正對(duì)齒面接觸性能的影響。根據(jù)擺線齒錐齒輪加工刀具和產(chǎn)形輪的形成原理,建立了加工擺線齒錐齒輪的數(shù)學(xué)模型。對(duì)不同曲率的齒面做了嚙合分析。通過算例分析,研究了刀盤半徑修正對(duì)嚙合參考點(diǎn)處相對(duì)主曲率的影響。編寫了TCA程序,得到不同刀盤切向半徑修正量的齒面接觸印痕。通過三維軟件建立大、小輪齒面的三維模型并進(jìn)行虛擬裝配,得到不同刀盤半徑修正的齒面在參考點(diǎn)處嚙合時(shí)的瞬時(shí)接觸橢圓。通過對(duì)比以及量化分析,得到接觸區(qū)長(zhǎng)度隨著刀盤半徑修正量的增加而變短的規(guī)律。為擺線齒錐齒輪刀盤參數(shù)的設(shè)計(jì)計(jì)算提供了參考。
[Abstract]:Aiming at the selection of the parameters of cycloidal bevel gear cutters, the influence of cutter radius modification on tooth surface contact performance is studied. According to the forming principle of cycloidal bevel gear, the mathematical model of machining cycloidal bevel gear is established. Meshing analysis of tooth surfaces with different curvature is made. The influence of cutter radius modification on the relative principal curvature of meshing reference point is studied by an example. The TCA program is written to get the contact mark of the tooth surface of different cutter head tangential radius correction. The 3D model of the tooth surface of large and small wheel is built by 3D software and virtual assembly is carried out. The instantaneous contact ellipse of tooth surface modified by different cutter radius is obtained when meshing at reference point. By comparison and quantitative analysis, the length of contact area is shortened with the increase of cutter radius correction. It provides a reference for the design and calculation of the cutter head parameters of cycloidal bevel gear.
