Some Properties of V-Ti Spheroidal Graphite Cast Iron Gears
-
摘要: 作者對等溫淬火的釩鈦球鐵齒輪進行了7種基礎性能試驗。結果表明:這種齒輪的接觸疲勞極限σHum值、抗磨損能力、結構阻尼比和降低噪聲等方面具有優良的性能,而彎曲疲勞強度較低。用這種釩鈦球鐵制造QJ系列減速器齒輪,其承載能力可提高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 σHlim the wear resistant ability, the structural damping rations and reducing the noise etc.
