Abstract:
This invention deals with guiding means for slides or similar moving parts of machine tools and similar machines. An object of the invention is the provision of an improved guide arrangement for such slides v or similar parts. Another object is the provision of guiding means which is capable of bearing relatively heavy loads without undue friction, so that the slide or similar part supported by this guiding means is movable relatively easily and freely, notwithstanding heavy load conditions.
Claim:
Guiding and supporting means for accurately guiding and supporting heavy relatively movable parts of machine tools and the like, said guiding and supporting means including means forming a V-shaped groove on one of said parts, means forming a V-shaped groove on the other of said parts, said grooves being faced toward each other and extending longitudinally in the direction in which the two parts are to be moved relatively to each other, and a series of a relatively large number of rollers spaced relatively closely to each other with the clear distance between adjacent rollers substantially less than the diameter of each roller, said rollers being placed between said two grooves and extending into both of them, said rollers having axial length slightly less than their diameters and certain of said rollers having their axes lying in a common plane at a substantial angle to the common plane of the axes of certain other rollers. |
