【摘要】 利用轴承组件轴向刚度的特性,采用精密力传感器开发了弹性预紧轴承组件预紧力测试台。利用该试验台可以实现对弹性预紧轴承组件预紧力的检测和弹性预紧限位行程的检测。加载组件采用精密螺旋弹簧实现了大载荷高分辨率的加载,并通过直线导轨保证加载力的加载方向。最后利用该试验平台对某弹性预紧电机轴承组件的预紧力进行了检测。更多还原

【Abstract】 A platform for testing bearing preload of spring preloaded shafting is developed,introducing a precision force sensor and taking advantage of the characteristic of axial stiffness.Tests of bearing preload and the restricted distance of spring preloaded shafting are carried out w ith this platform.Precision coil springs are used in the load applying assembly,actualizing heavy and high resolution load apply,and a linear track is used to insure the loading orientation.Furthermore,tests on preload of a spring preloaded motor shafting are achieved using this testing platform.更多还原
