To　overcome　the　problem　of　these　parameters　that　are　difficult　to　obtain　from　the　test　measurement　directly,　this　paper　investigated　the　influence　of　wear　degradation　of　linear　ball　guides　on　other　parameters.　Considering　the　sufferance　load,　the　deformation　and　the　initial　preload　of　each　ball,　the　models　of　stiffness　degradation,　preload　degradation,　contact　angle,　critical　load,　friction　coefficient,　friction　and　maximum　creepage　directly　related　to　the　wear　degradation　are　established,　respectively.　With　the　wear　degradation　of　linear　ball　guides,　the　stiffness　and　preload　of　linear　ball　guides　generate　degradation　ordinarily.　Meanwhile,　other　parameters　of　linear　ball　guides　such　as　contact　angle　of　the　ball　in　upper　row　and　lower　row,　critical　load,　friction　coefficient,　friction　and　maximum　creepage　are　liable　to　resonate　varieties　dramatically.　The　parameters　involved　above　have　an　important　significance　in　the　performance　of　linear　ball　guides.　In　terms　of　a　certain　type　of　domestic　linear　ball　guide,　a　series　of　simulation　were　analyzed　based　on　the　established　models.　Result　shows　that　the　wear　degradation　of　linear　ball　guides　affects　other　parameters　to　a　different　degree.　The　method　of　the　wear　measurement　of　linear　ball　guides　can　effectively　predict　the　change　regulation　of　other　parameters.　©　2017,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
