摘　　要：针对弹性支承一体化轴承径向刚度测量存在的问题和难点,分析了在径向载荷下测量径向刚度的主要影响因素:外力作用下外圈鼠笼式弹性支承结构的弹性形变和钢球与沟道间的接触应变。经过推导最终给出了通过测量外圈径向刚度计算整套轴承径向刚度的方法。Aiming at problem and difficulty of radial stiffness measurement for bearing integrated with elastic support,the main factors influencing radial stiffness measurement are analyzed under radial load,namely flexible deformation of outer ring squirrel cage elastic support structure under external force and contact strain between steel ball and raceway.After derivation,the calculation method for radial stiffness of entire bearing is eventually given by measuring radial stiffness of outer ring.
