Analytical and Finite Element Modeling of the Dynamic Characteristics of a Linear Feeding Stage with Different Arrangements of Rolling Guides

Figure 2

Schematic of contact geometry of a rolling guide with four rows of rolling balls, forming a two-point contact mode within each ball groove. The contact mode can be regarded as a type of Hertzian contact mode. In the figure, and represent the contact angle and contact force, and and are the radii of rolling ball and ball grooves, respectively. (b) Modeling of linear rolling guide.
