摘　　要：针对双柱式锻造液压机工作缸球铰结构缺乏准确理论分析的问题,建立了球铰支承的力学分析模型,研究了球铰支承的摩擦阻力矩和球铰结构的摩擦圆半径,确定了双球铰和单球铰连接对活动件的侧向推力,阐述了球铰转动的条件和球铰侧向推力对工作缸受力分析的重要性,分析了影响球铰侧向推力的因素和双球铰、单球铰结构的适用范围。Aiming to the lack of accurate theoretical analysis of spheric joint of working cylinder for double column type forging hydraulic press,a mechanical model for spheric joint support is presented and the frictional resisting moment of spheric joint support and the radius of friction circle is discussed to determine the double spheric joint and single shperic joint＇s lateral thrust to the moving parts. By elaborating the importance of spheric joint＇s rotation condition and lateral thrust to the force analysis of working cylinder and analyzing the factors that influence the lateral thrust of spheric joint and the applicable scope of double spheric joint and single spheric joint sturctures,a further research of the moving parts＇ rotation of double column type forging hydraulic press and the eccentric forging＇s function mechanism to the main working cylinder could be made.
