Studies of linear ball guideways’ fractal wearmodel and accuracy degradation
摘要
Abstract
Based on the Hertz contact theory , a mechanical model of linear ball guideways was built to study the wear rule and accuracy degradation of linear ball guideways .The contact area between the ball and the slider ’ s raceway was characterized by the fractal function , and the raceway ’ s fractal parameters were obtained by using the structure function analysis method .Under the considering of the lubrication state between the ball and the slider ’ s raceway , the asperities load capacity was obtained by using the fractal contact model .The wear between the ball and slider’s raceway was analyzed through the adhesive wear theory , and then , the fractal wear model of linear ball guideways was established with the creep theory .Finally, the simulation analysis for a certain type of the linearball guideway was conducted , and the wear rules and accuracy degradation of the linearball guideway under different loads and running distance were obtained by the calculation simulation .关键词
