RISEvolution of Lubrication Characteristics of Double-Nut Ball Screws Based on an Efficient Surface Roughness Modeling Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate prediction of lubrication characteristics, specifically film thickness and pressure distribution, is pivotal for ensuring optimal performance in ball screws. Despite its significance, there is a notable dearth of ...
A New Wear Prediction Method for Degrading Linear Motion Ball Guides Based on Universal Kriging
Publisher: The American Society of Mechanical Engineers (ASME)
A New Two-Stage Degradation Model for the Preload of Linear Motion Ball Guide Considering Machining Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Preload, which is widely applied in linear motion ball guide (LMBG) to eliminate clearance and increase stiffness, gradually decreases owing to wear, resulting in the degradation of the load-bearing capability and dynamic ...
Effects of Eccentric Errors on Sliding Velocity and Accumulative Wear Depth of Planetary Roller Screw Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The eccentric errors of planetary roller screw mechanism (PRSM) affect the contact kinematic characteristics and exacerbate the cumulative wear of thread pairs, which will reduce its transmission accuracy and reliability. ...
