<p>The invention relates to a spherical guiding system as a component of aΔrobot, employed in the field of mechanical engineering.. According to the invention, the system comprises a short shaft () provided with some ball journals () with contact by rolling friction, two half-bearings () which are fixed to one end of some levers () and arranged symmetrically-opposite to the short shaft (), two other half-bearings () being similarly fixed to the other end of the levers (), each of the said half-bearings () comprising a ball race () where the balls recycling is provided by a shoulder (), a support (), a semi-body (), where the presence of a wiper () prevent possible impurities from entering the rolling zone, the contact between the opposite half-bearings () and the ball journals () being provided by an expansion-tensioned helical spring ().</p> |
