摘　　要：从特大型回转窑项目实施面临的大件(轮带、大齿圈和筒体)运输、齿轮的承载能力等问题分析入手,提出了设计和适合于现场的制作方案;通过力学平衡实例解算,解决了回转窑用自定位滑履轴承设计的关键技术——滑履托瓦倾角的确定;通过齿轮变位系数选择与分配、螺旋角的选择,解决了常规模数回转窑齿轮承载能力小的问题;运用比照法对特大型回转窑的设计方案进行评估,得出结论:使用滑履轴承、多瓣组合大齿圈、现场组焊滑环、现场制作筒体、现场切削焊接坡口和垫板外圆,可以解决特大型回转窑项目实施的大件运输问题;通过对变位系数进行合理分配和采用斜齿轮传动,可以满足大功率传动要求;采用自定位滑履轴承,不但省去了挡轮装置,而且使滑履与滑环接触面自动吻合,可以避免热工制度改变和操作等原因造成的轮带和托轮不正常磨损。From the project of large rotary kiln in the implementation of large（wheel,gear ring and cylinder）of transport,gear bearing capacity problems,puts forward the design and suitable for the on-site production plan;through the example of mechanical equilibrium solution,solves the key technology to determine the self positioning slide shoe bearing design of the sliding pillow with the angle of the rotary kiln;through the modification coefficient of the gear selection and distribution of spiral angle and choice,solve the bearing capacity problem of small modulus gear of conventional rotary kiln;the use of contrast method for large rotary kiln design evaluation,draw the conclusion：the use of sliding shoe bearings,gear ring,combined with multi site group welding ring,on-site production of cylinder,spot welding groove and cutting plate outer circle,can solve the large project type rotary kiln implementation of the transportation problem;based on the displacement coefficient Rational distribution and adopt bevel gear transmission,can meet the requirements of high power transmission;the self positioning slide shoe bearing,not only eliminates the block wheel device,and the sliding contact surface of the shoe and the slip ring automatic anastomosis,can avoid thermal system change and operational and other reasons caused by the tyre roller is not normal wear and tear.
