Omnidirectional spherical roller caster |
摘要 |
A caster capable of omnidirectional transport having a spherical roller freely mounted within a housing having a concave spherical cavity. A plurality of cylindrical bores is disposed perpendicular to the inner concave surface in equilateral geometric configuration, axially converging toward the center of the cavity. A plurality of small internal caster assemblies, mounted for free independent rotation about the convergent axis, extend from within the bores to contact the spherical roller, thereby creating a loading surface capable of providing omnidirectional rotation. The spherical roller interfaces between the loading surface of the cavity and a surface onto which the entire caster assembly is imparted omnidirectional movement.
