“…The precision sustainability of the ball screw is defined as the ability to maintain a specified precision grade, which causes the travel variation and the travel deviation within the useful travel to be limit in specified precision range. 4 The relation of the travel deviation, travel variation, and precision allowance of the ball screw within specified useful travel are expressed as where ΔPem ( m = a or c , the subscripts a and c denote the information after applied load and before applied load, respectively) is the precision allowance of the travel deviation within useful travel, which is the algebraic difference between the measured travel deviation esm and the permitted travel deviation within useful travel ep based on the ISO 3408-3-2006 standard. ΔPnm ( n = u , 2π, and 300 describe the travel variation within useful stroke L s , 300 mm stroke and 2π rad, respectively) denote the precision allowance of the travel variation within useful travel, which is the algebraic difference between the measured travel variation Vnm and the permitted travel variation within useful travel Vup on the basis of the ISO 3408-3-2006 standard.…”

“…1,2 When the ball screw is subjected to the external load, the load between the driving screw and the nut is transferred by all balls. 3,4 In the past, it was assumed that the contact load between all balls and raceways was uniform under the external load, and the load difference of all balls was ignored, which seriously affected the position accuracy of ball screws. In addition, the axial contact deformation displacement varies with the load distribution change of all balls in running process, and the position accuracy is affected by the deformation displacement.…”

The accurate model of the load state for all balls under multidirectional load is very helpful for the design process of ball screws. The contact deformation model of the ball screw without consideration of the stress difference of all balls is inaccurate. In this paper, a novel contact load model of the ball screw is established by considering coupled axial, radial load to study the elastic deformation displacement and position accuracy. The deviation and variation of axial elastic deformation with the dimension errors of all balls are investigated to obtain the influence of load state on the precision sustainability of the ball screw. The position precision including travel deviation and variation by considering load distribution of all balls is studied under the different load conditions. In addition, a new working bench is designed to study the position precision of the ball screw. The experimental study is carried out to obtain the relationship between the position precision and the contact load state of all balls, which is a reference to compensate for the precision loss of the ball screw.

“…However, Luo [12] and Horng [13] et al established the two-body microscopic wear model based on micro-contact theory, in order to explain the relationship between the wear depth and the actual feed stroke. Zhao [14,15] took the double-nut preloaded ball screw as the research object, and successively studied the wear behavior through modeling and experimental verification. According to the research basis [7,9,10], Liu and Ma [16] introduced fractal theory into wear modeling to study the accuracy degradation mechanism of the BS.…”

The ball screw (BS) has become an indispensable key functional component in many fields, such as CNC machine tools, precision transmission system and special service requirements. Its accuracy reliability is a key performance in many application fields. There is a phenomenon of mixed slip-roll motion during the BS operation, however, both non-constant working conditions and mixed sliding-rolling motion mode affect the its accuracy decay. In this paper, the modeling method of accuracy decay for mixed sliding-rolling motion behavior is established under non-constant operating conditions. The accuracy reliability of the BS is analyzed under single non-constant operation condition or multiple non-constant operating conditions, and the accuracy decay is predicted though modeling method proposed. In addition, the experimental analysis of the BS accuracy degradation is carried out under three different amplitudes of AL (non-constant axial load), FR (non-constant feed rate) and AL+FR combination conditions. The average value of the accuracy loss relative error between theoretical model and experimental test results is smaller than that under pure sliding motion. It shows that the accuracy decay analysis model established is beneficial to predict the BS accuracy reliability.

“…Wear is one of the main reasons for the accuracy failure of the transmission functional components. Accuracy retention of transmission functional components such as guide rails 1 and ball screw 2,3 has an important influence on the machining accuracy of CNC equipment such as machine tools. And, it is necessary to establish the relationship between the wear behavior of functional transmission components and its accuracy degradation law.…”

At present, wear models and accuracy prediction of guideway are established based on elastoplastic mechanics of continuous media. These methods are limited to describe the process of accuracy degradation by using the material performance defined based on macroscopic hypothesis condition. In this paper, the multiscale method based on quasicontinuum medium(QM) principle is proposed to describe the degradation process of guideway linear precision with an exponential model. According to the wear distribution of the guideway surface with the micro-morphology evolution process, the measurement value of the guideway linear precision is modeled systematically. Then, using the quasicontinuum medium method instead of the continuum hypothesis, the exponential wear model of guideway is established. The exponential wear model uses the wear exponent to describe the wear status based on linear precision measurement rather than tremendous wear volume tests. By means of Depth From Defocus (DFD) method, the micro-topography information of the guideway surface is obtained. Therefore, the wear state of the guideway is verified under different loading conditions, and the validity of using the QM method to establish the guideway exponential wear model is verified.
