二辊轧机的传动设计 摘 要 轧机是实现金属轧制过程的设备。泛指完成轧材生产全过程的装备，包括主要设备、辅助设备、起重运输设备和附属设备等。但一般所说的轧机往往仅指主要设备。 随着钢铁加工工业结构调整步伐的加快，小型轧机生产技术装备的发展趋势正在向大坯重、连续化、高精度、高质量方向发展。小型材的种类也正在从普通钢向合金钢、高精钢方向发展。现代轧机发展的趋向是连续化、自动化、专业化,产品质量高,消耗低。 本次对轧机电动机、轧辊、轴承及轴承座以及压下装置中蜗轮蜗杆减速器进行了设计和说明。轧机在轧制的过程中，轧件的厚度主要受轧辊的结构和压下调整装置的限制，因此对轧辊的结构的设计和强度的校核以及蜗轮减速器的设计是本次设计的主要方向。 关键词：轧机，轧辊，蜗杆，蜗轮，轧件 Diameter 320 duo mill transmission designs ABSTRACT The rolling mill is the apparatus which realizes the rolling course of metal. Refer to finish rolling the material and producing the overall equipment in general, include the capital equipment, auxiliary equipment, transporting equipment of jack-up and accessory equipment and so on. But generally said rolling mill often only means the capital equipment. With the quickening of steel and iron processing industrial restructuring paces, the rolling mill development trend for producing technical equipment of miniature rolling is heavy to the big base, melt continuously, high precision, high-quality direction develop. The steel of the small-scale material is also being developed from steel of general to the Alloy steel and to the High accuracy copper. The trend of development of modern rolling mill is melting continuously, automation, specialization, high in quality, low to consume. This time to in the rolling mill electric motor, the roller, the bearing and the bearing seat as well as the holding-down device the turbine wheel worm reducer has carried on the design and the explanation. Rolling mill in rolling process, rolled piece thickness mainly roller structure and holding-down device adjustment limit, therefore the breaker roll structure design and the intensity examination as well as the turbo-accelerator design is this design main direction.
