【摘要】 双圆弧弧齿锥齿轮是将圆弧齿廓点啮合传动形式运用于锥齿轮传动的一种新型的齿轮传动方式,其基本齿廓是分阶式双圆弧齿形,现有的分析表明,它具有承载能力高、使用寿命长、加工简单等优点,是一种具有广阔应用前景的新型弧齿锥齿轮传动方式。 双圆弧弧齿锥齿轮采用等高齿,在轮齿任意法截面内具有完全相同的齿形,由于采用平面齿轮原理加工,能形成点接触共轭齿面,符合齿廓啮合的基本定律。短齿形的采用,按内端法面模数进行设计,保证了内端轮齿具有足够高的弯曲强度。FSH型分阶式双圆弧齿形(短齿形),其轮齿从内端到外端的齿形分布,是由短齿型向超短齿型逐步过渡,如果合理选用重合度,适当利用轮齿外端粗厚部分,则锥齿轮的承载能力及使用寿命可以得到更大的提高。 本文阐述了弧齿锥齿轮副点啮合共轭齿面的形成原理,同时还论述了双圆弧弧齿锥齿轮基本啮合原理,推导了弧齿锥齿轮的齿面方程;并按照等强度设计的原则选用FSH型分阶式双圆弧齿形(短齿形)进行研究。由于齿面形状比较复杂,很难通过基准齿形的空间旋转、平移等变化形成准确的齿面,所以要建立一个准确可靠的双圆弧弧齿锥齿轮的有

【Abstract】 Double circular arc spiral bevel gears is a new gear transmission mode by using arc gear teeth dot mesh transmission method as spiral bevel gears transmission method. Its basic gear tooth profile is double circular arc spiral bevel gear tooth profile. Analysis proves that this tooth profile has much advantage, such as its high bearing loads and its long use life-span and its easy manufacture process.Double circular arc spiral bevel gears apply equal-high gear tooth, and its gear profile is equal in any vertical plane, this gear profile can form dot-contact conjugate gear surface for adopting plane gear theory to make gear, and this gear profile abide by the gear profile meshing elementary rule, the apply of short-tooth and the design of according to small-section vertical plane modulus assure that small-section gear surface own very high bend strength. To FSH step double circular arc spiral bevel gears tooth (short-tooth ) , its gear teeth of distributing from small-section to big-section
