1、JLY3809机立窑(总体及传动部件)设计摘要:目前,机立窑存在二大技术和工艺难点:一是立窑煅烧热工不稳,严重影响水泥各项物理性能;二是立窑单窑产量低,不能适应当今各行各业的发展形势。因此,JLY3809机立窑在这种情况下应运而生。而机立窑的传动装置在机立窑的整体结构中起到极其重要的作用。在对生产现场全面调研的基础上,对生产现状进行了有效分析,确定了传动装置的总体设计方案。为了提高水泥生产中机立窑的传动效率,满足生产工艺和生产量的需求,应用最优化方法,确定速比系数的分配,大、小齿轮的设计。设计了轴的结构,进行了轴的强度校核计算。确定
2、了机立窑转速,选择合理的润滑形式。另外,大立轴是传动的主要部分,带动塔篦子低速转动,承受巨大的载荷,是保证机立窑正常工作的关键,因此需要有高的可靠性、良好的稳定性和合理的经济性。通过几种方案的比较,轴承的选择采用了最优的设计方案,从而增加机立窑的传动平稳性和使用寿命,大大提高了机立窑运转率。机体工作运行平稳,安装维修方便。关键词:机立窑;传动装置;优化;大立轴Theoverallandtransmissiondevicedesignof3809mechanicaluprightkilnAbstract:Therearetwomain
