| 中文摘要: |
| 目的 针对目前辊齿堆焊修复模式单一，单面修复导致的热变形大、易产生裂纹等问题，设计一种新式辊齿自适应堆焊修复设备。方法 设备采用一种凹形夹持装置，通过对辊齿双面同时修复以降低修复过程所产生的热变形，并将修复夹持装置设置为可活动式结构，以便适应不同厚度的辊齿修复，提高辊齿的修复效率。结果 对不同磨损程度的辊齿，系统可以自动选择小角度、大角度或非对称模式进行修复;修复层表面平整，界面结合良好，辊齿变形小，无明显的气孔、夹渣和裂纹等修复缺陷。结论 开发的新型的单辊辊齿修复系统，能够实现单辊辊齿自适应修复。 |

| The work aims to design a new roll tooth adaptive surfacing repairing equipment to solve the current problems of single surface repairing mode of roll tooth, large thermal deformation caused by single-sided repairing in the repairing process, and easy generation of cracks. The equipment was designed with a concave clamping device to reduce the thermal deformation generated by the repairing process by repairing both sides of the roller teeth at the same time, and setting the repairing clamping device to a movable structure to adapt to roller teeth with different thicknesses and improve the repairing efficiency of roller teeth. The repairing model of large-angle repairing, small-angle repairing, or asymmetric repairing can be chosen automatically according to the different abrasion of roll tooth. A smooth repairing surface, excellent bonding interface of repairing layer, and minor deformation of roll tooth can be attained. Moreover, no gas cavity, slag and cracks can be detected with metallographic determination. The new single roll tooth repairing system developed can achieve adaptive repairing of single roll tooth. |
