Refer to Fig.5 for examples of such mechanisms.Two <strong>LM</strong> blocks on single railThree or more <strong>LM</strong> blocks on single railFour <strong>LM</strong> blocks on 2 rails1Two <strong>LM</strong> blocks on 2 railsSix or more <strong>LM</strong> blocks on 2 rails: Rotating mechanism: Rotating mechanism and slide mechanismFig.5 Examples of Table MechanismsFig.6 shows examples of designing a table when units are used on multiple axes. HMG requires arotating mechanism and a slide mechanism since the table is decentered when an <strong>LM</strong> block transitsfrom a straight section to a curved section. The amount of decentering differs according to the radiusof the curved section and the <strong>LM</strong> block span. Therefore, it is necessary to design the system inaccordance with the corresponding specifications.Fig.7 shows detail drawings of the slide and rotating mechanisms. In the figure, <strong>LM</strong> <strong>Guide</strong>s are usedin the slide mechanism and Cross-Roller Rings in the rotating mechanism to achieve smooth slidingand rotating motions.For driving the Straight-Curved <strong>Guide</strong>, belt drives and chain drives are available.Straight sectionRotation + slideRotation + slideSlide distanceof the tableRotation + slide2<strong>LM</strong> <strong>Guide</strong>Rotation + slideCross roller ringRotation<strong>LM</strong> <strong>Guide</strong><strong>Industrial</strong> <strong>Technologies</strong>Rotation + slide<strong>LM</strong> <strong>Guide</strong>Cross roller ringRotationRotationCurved sectionRotation + slideRotationFig.6Fig.7A1-249
