镶套支承辊的结构改进

Improved Shelled Backup Roll Structure

常规镶套支承辊在使用中常出现辊套开裂、轴向窜动及周向转动等现象,严重影响生产,使用寿命不能满足市场需要。在实验基础上,通过合理设定过盈量,改进滚套装配的结构形式,改进加工工艺,增加检测方法,以及使用防松剂等方法,有效提升镶套支承辊的制造质量,延长了使用寿命。

Cracking,axial and circumferential shifting often occur on the shell of conventional shelled backup rolls during usage,which have significant negative influence on production and shorten the service time of shelled backup up rolls.In order to solve this problem,the paper puts forward a solution to improve the workmanship and prolong the service time of shelled backup rolls by setting up proper shrink range,modifying roll shell structure and machining techniques,performing more examinations and using lock compounds.
