Abstract:
To convert rotary motion into translational motion in modern metal-cutting machine tools, screw-nut rolling transmissions are widely used. Special requirements are placed on the stability of the operational characteristics of the screw-nut rolling transmission. The influence of the accuracy of manufacturing screw-nut transmission on the main transmission characteristics: axial stiffness and the moment of idling is considered. When analyzing the quality of the manufacture of the transmission, the following manufacturing errors were taken into account: the pitch errors of the screw and nut threa

Abstract:
For ball screw feed system, it has been a common practice that screw shaft is typically supported by bearings at both ends and is driven by a servo motor through coupling. However, this drive method has a relative low dynamic rigidity due to the influence of the support bearings. In this study, the nut-direct drive system is proposed, where the screw shaft is fixed at both ends and the screw nut is driven by the hollow servo motor through the bolted flange. In order to analyze the advantages of the nut-direct drive system compared with the classical drive, the dynamic models of the classical d

Abstract:
A ball-screw system is widely used in high speed transmission platforms. High transmission speed brings high frictional force, heat and thermal expansion occurring on contact areas of ball, screw and nut. Positioning error of platform is affected by the thermal expansion during linear transmission. A vertical motion of ball-screw driving system was used for high speed transmission test. Thermal expansion of screw and positioning error were measured for discussion their effects. Cyclic vertical motion during a long transmission distance, 2 km, will integrate thermal heat to ball, screw and nut,

Abstract:
Experimental studies were carried out to estimate the friction coefficients for a screw-nut threaded pair made of spatially reinforced carbon-carbon composite materials (CCCM). Quantitative values were obtained for the thread friction coefficient and nut end friction coefficient. The ultimate screw-in torque for the CCCM threaded pair was determined, and its failure mode at a destructive screw-in torque was established. The laboratory tests were carried out to measure the tightening force. The nut screw-in torque was measured using a torque wrench.

An integrated modeling method is proposed for ball screw drives which incorporates the elastic deformation of the screw within the nut. The ball screw model is derived based on Rigid Finite Element method, which is modeled as rigid multibody system consisting of rigid finite elements connected with spring damping elements, by using Rigid Finite Element method. The distributed contact stiffness of screw-nut interface is converted on ball screw and nut via Frenet-Serret coordinates. The proposed ball screw model has much less degrees of freedom than conventional finite element models. Comparison

Axially heavy-loaded screw pairs are widely used in rolling mill press systems and other heavy equipment. During the working process, the nut is pressed at both ends, which causes equivalent stress at the thread roots in a U-shaped distribution along the height. Thread roots at the ends tend to suffer fracture failure when the equivalent stress is too great. In this article, the finite element software ANSYS is used to establish a 3D model of screw pairs and analyse bearing characteristics.
