ROLLING MOTION GUIDES AND SYSTEM OF SUCH GUIDES Russian patent published in 2006 - IPC B23Q1/01 F16C29/04 

FIELD: machine engineering, possibly metal working machine tools with moving working organ, designs of devices, manufacturing equipment units.

SUBSTANCE: rolling motion guide includes rack and carriage supporting rollers. Axes of rollers are arranged in parallel planes normal relative to axis of rack. The last has three rolling planes inclined one to other; two rolling planes are designed for rollers (of carriage) touching them by means of cylindrical surfaces along lower generatrix. Third plane is used for rolling carriage roller touching it by means of cylindrical surface along upper generatrix. Angle between rack rolling planes are selected according to condition preventing carriage shift in direction different from its motion direction. Rolling guides system includes two mutually spaced rolling guides and it may include in addition rolling guides having rack with two rolling planes inclined one to other or with two parallel and horizontal planes. Several planes are designed for rolling roller of carriage that touches respective plane by means of cylindrical surface along its lower generatrix; other planes are used for roller of carriage that engages with respective plane by means of cylindrical surface along its upper generatrix.

EFFECT: continuous noiseless motion of carriage with working organ along large distances at minimum friction factor and without shifting in direction different from its motion direction.
