Technological Equipment, Machining Attachments and Instruments I International Scientific and Practical Conference « Actual Problems in Machine Building » ________________________________________________________________ 228 About parameters influencing the stiffness modular type roller guide system B.M. Ryvkin, V.V. Molodtsov The article is devoted - the main problem of selection and calculation of of modular type roller guide system which is statically indeterminate mathematical model and estimation of their stiffness and equivalent load, because in catalogs of manufacturers often lack the necessary data. Some manufacturers (eg «Bosch Rexroth» and «Schaeffler KG» Germany, «SCHNEEBERGER», Switzerland) lead a graph of the simplest forms of multiple loads. That's not enough for forming machine system design and evaluation of its stiffness as a whole, because the guide system modular type are able to perceive the whole complex loads (forces and torques) simultaneously in five directions. Keywords : roller guide system, stiffness, rail, wedge, roller, contact.
