Abstract:
A device for holding a part comprising a retainer member provided with an attaching and holding part, said retainer member having a convexly spherical surface section and a surface section for applying the part to be held, and a receptacle member provided for a rotatable bearing for the retainer member, said receptacle member having a concavely spherical surface section forming a glide seat surface for receiving the convexly spherical surface section of the retainer member, the improvements comprising glide means for reducing the friction between the spherical surface sections of the retainer member and the receptacle member, said glide means temporarily producing a gas glide layer between the spherical surface sections and said glide means temporarily producing an under-pressure between the spherical surface sections having at least one extraction opening fashioned in at least one of the two spherical surface sections for extracting the gas from the interspace between the two spherical surface sections.
