“…In his study, on the basis of describing the motion of a ball in a ball screw system, he analyzed the slipping between the ball and screw (or the nut) and established the analytical equation, which proved the assumption of no slipping between ball and raceway in the previous is unattainable (Levit, 1963;Drozdov, 1984). Wei et al (2009) inherited the previous researchers and described the slipping behavior arising at two contact areas between the ball and screw (or nut), while considering variable contact angles and elastic deformations under the running condition. Also, in a later work they introduced an analysis method to evaluate the mechanical efficiency of the ball screw and obtained its curve in a closed system.…”

“…Also, in a later work they introduced an analysis method to evaluate the mechanical efficiency of the ball screw and obtained its curve in a closed system. Due to the increasing application of high-speed and high-precision ball screw, Wei et al (2009);Mu and Feng (2011) set out to establish the analysis model of transmission efficiency for a preload ball screw operating at high speeds, and Mu and Feng (2011) proposed the slipping of ball screw would be effected by the centrifugal force under the high speed state. However, the centrifugal force how to influence on the ball screw slipping hasn't been further analyzed.…”

This paper aims to set up the ball systematic slipping model and analyze the slipping characteristics caused by different factors for a ball screw operating at high speeds. To investigate the ball screw slipping mechanism, transformed coordinate system should be established firstly. Then it is used to set up mathematical modeling for the ball slipping caused by the three main reasons and the speed of slipping can be calculated. Later, the influence of the contact angle, helix angle and screw diameter for ball screw slipping will be analyzed according to the ball slipping model and slipping speeds equation and the slipping analysis will be obtained. Finally, curve of slipping analysis and that of mechanical efficiency of the ball screw analysis by Lin are compared, which will indirectly verify the correctness of the slipping model. The slipping model and the curve of slipping analysis established in this paper will provide theory basis for reducing slipping and improving the mechanical efficiency of a ball screw operating at high speeds.

“…Therefore, it is very important to affect the wear and precision retaining ability of the BSM. Wei [1][2][3] introduced the theory of differential geometry of curve to analyze the motion rules of a ball considering the effect of the elastic deformation of contact angle and found that the self-spin and rotational angular velocities of the ball have an approximately linear relationship with the rotational velocity of the screw. Lin et al [4][5] confirmed the existence of both the rolling and sliding motions relative to each other between the ball and raceway during the operation of BSM and proposed a calculation model to estimate the transmission efficiency.…”

Abstract.To study the effect of contact and helix angles on slide-roll ratio at the ball contact point under the uniform motion state of ball screw mechanism (BSM), a slide-roll ratio model was derived in the literature [9] were used in this paper. It also conducts a simulation analysis of the slide-roll ratio relationship between the uniform motion at the ball center and ball contact point under different contact angle and helix angle. As shown by the analysis, with the increase in the BSM's contact angle, the slide/roll ratio at the contact point decreased, and the contact angle had a relatively significant effect on the slide/roll ratio; however, with the decrease in the BSM's helix angle, the slide/roll ratio at the contact point decreased, and helix angle had a relatively insignificant effect on the slide/roll ratio.

The dynamic behavior of adjustable preload double-nut ball screw has been investigated by finite element simulation model under different environmental temperature conditions. The simulations focus specifically on the effects of the ambient temperature (5~55°C) on the torque acting on the flange of the ball screw mechanism at rotational speeds of 50~1000 rpm. The environment temperature effect was less studies to discuss the heat deformation issue of ball screw. The validity of the simulation results is confirmed by comparing the predicted torque values with the experimental measurements. It is shown that the torque decreases logarithmically with an increasing temperature due to a change in the expansion coefficients of the ball screw mechanism components and a reduction in the viscosity of the ball screw lubricant. In particular, for a rotational speed of 1000 rpm, the torque reduces by approximately 75.6% as the environmental temperature is increased from 5 to 55°C. However, for a constant temperature, the torque decreases with an increasing rotational speed due to centrifugal effects. For a low-rotational speed of 100 rpm, a good qualitative agreement is observed between the simulated torque and the measured torque at higher temperatures. However, in the low-temperature regime (e.g., 5°C), the simulated torque is around 47.6% lower than the measured value.
