Static structural behaviour of wire bearings under axial load: Comparison with conventional bearings and study of design and operational parameters

Influence of the geometrical design on ball and crossed roller wire race bearing behavior under axial load

“…This phenomenon may not be considered directly as a performance indicator, but it has a significant contribution to the understanding of the performance of the bearing, as it will be observed in following sections. Wire twist arises when the bearing is loaded because the contact force exerts a twisting moment [6]. This phenomenon turns beneficial since, this way, the ballwire contact tends to remain centered within the raceway thus preventing early contact patch truncation and allowing the wires-roller set behave as a single solid.…”

“…It is the angle between the radial plane and the normal force vector sum of the rolling element-wire contact. The variation of this angle comes from phenomena such as ball climbing (only in ball bearings) and wire twisting [6], and it is an indicator of the position of the contact. The knowledge of the variation of this indicator retrieves valuable information of the behaviour of the bearing for its analytical modelling.…”

“…In the second one they proposed a corrected wire-raceway geometry for ball wire race bearings that reduces the free edge stress concentration effect [5]. Martin et al studied the behaviour and the influence of some design parameters in ball wire race bearings under axial load, explaining the wire-twisting phenomenon and comparing the results with equivalent conventional bearings [6]. In terms of analytical models, Shan et al proposed an analytical method to obtain the preload in ball wire race bearings with non-conformal ball-wire contact [7].…”

Industrial Product Quality Analysis Based on Online Machine Learning

“…The bearing is a crucial component of modern industrial equipment, serving the primary function of providing support to mechanical rotating bodies, reducing friction coefficients during movement, and ensuring rotational accuracy [9,10]. The precision, performance, lifespan, and reliability of bearings are all vital in the production process.…”
