钒钛球铁齿轮的基础性能

Some Properties of V-Ti Spheroidal Graphite Cast Iron Gears

摘要: 作者对等温淬火的钒钛球铁齿轮进行了7种基础性能试验。结果表明:这种齿轮的接触疲劳极限σ_Hum值、抗磨损能力、结构阻尼比和降低噪声等方面具有优良的性能,而弯曲疲劳强度较低。用这种钒钛球铁制造QJ系列减速器齿轮,其承载能力可提高50%。

Abstract: Seven kinds of properties for V-Ti spheroidal graphite cast iron gears have been investigated. The results show that these gears have advantages, such as the endurance limit values σ_Hlim the wear resistant ability, the structural damping rations and reducing the noise etc.
