摘要辊压机轴承座在制造过程中需要进行焊接，焊接的残余应力对构件的强度、疲劳寿命及结构变形等方面均十分有害，需要消除轴承座焊接后的残余应力。采用振动时效技术消除残余应力，操作简便、用时短、成本低、节省能源、消除效率高，经振动时效技术处理后的轴承座应力消除率的52.91%，完全能满足JG/T 5426-2005标准中应力消除30%以上的要求。

Abstract: The bearing housing of roller press needs to be welded in the manufacturing process, and the welding residual stress is very harmful to the strength, fatigue life and structural deformation of the member, so it is necessary to eliminate the welding residual stress of the bearing block. The technology of vibratory stress relief is simple operation, short time, low cost, energy saving and high efficiency, the stress relief rate of the bearing seat treated by vibro-aging technology is 52.91%, which can completely meet the requirements of JG/T 5426-2005 standard to achieve the stress relief above 30%.

Key words: vibratory stress relief heat treatment bearing housing residual stress
