过盈联接在包钢φ400机组轧管机齿轮座改造中的应用

The application of interference connection in the reconstruction of the φ400 tube mill gear housing in Baotou Iron and Steel Co.

采用过盈联接传递大扭矩方法,结构简单,不需要任何紧固件,联结定心自位好,承载能力高。

With interference connection to convey torque,the structure is simple and does not need any fasteners.And it has good selfcentering property,strong loadbearing capability,good performance in bearing interchanged and impace load safe and reliable,and can meet the lowest life for continuous production.The process is introduced in which the best thermal assembly parameter was determined.It has been proved that the design is very successful.
