| 摘要 |
The invention discloses a sphere rotary articulation, with synchronized running, which comprises an articulation outer part having an inner recess with a partially conical inner surface, wherein first sphere landing strips are longitudinally arranged, which form longitudinally extending guide bridges, said guide bridges being in an alternate relationship with an articulation inner part placed inside the inner recess having a partially spherical surface, wherein second longitudinally extending sphere landing strips are formed, which are in an alternate relationship with those spheres transferring a rotary moment, as well as a cage for spheres having spherically trimmed inner and outer surfaces, said cage receiving the spheres in different cage small windows, wherein a first portion of the guide bridges is defined by a spherical surface extending through the axial length of the articulation inner part, and with a second portion of the guide bridges comprising a reduced axial end with the articulation inner part having a higher landing strip depth about the periphery which is below the corresponding spherical surface.
