摘要：
A theoretical relationship for basic dynamic load rating based on a three-parameter life equation for a linear motion ball guide (LMBG) system is derived, including the effect of crowning on guide block, by calculating accumulated stress cycles on rail and guide blocks, rolling body load and equivalent average ball load. The values for basic dynamic load rating are than calculated for different strokes, load eccentricities and conformity factors. A life test is carried out for both the LMBG system and component. The test data are analyzed by three-Parameter Weibull distribution and the effect of crowning is clarified.
