Spherical bearings

The innovation "relates to spherical bearings in which the partially spherical outer surface of the one-piece inner ring". in a 'corresponding hollow spherical inner surface - a>.' V outer ring is slidably mounted. - .:: - '"\ ~ - ~ - - -' ■ .; _:

In such bearings, the center bores of the bearing inner rings have so far been made in -fitting dimensions for a tight fit: on a skin. The attachment of such spherical plain bearings "on shafts" creates many difficulties in practice, especially when _: the bearings are at a greater distance from the end. . ; ■■■ · - must be attached to longer shafts, λ:: -;:: ■: - ": - ■"

To avoid these difficulties: according to the present. Firing suggested at one.

which is just as ^ BSmessen as that of the bearing inner ring. Preferably, the eccentric sliding surfaces of the Inner bearing ring and the clamping ring tapered conically to the bearing center lain.

This design of a spherical bearing enables the bores of the bearing inner ring to be dimensioned so that the inner ring can be pushed onto a shaft without any significant expenditure of force, since the inner ring is only fastened to the shaft by tightening the clamping ring or the clamping rings he follows. - |; v ^:. : ■■ ^; - ': "^;-; -: \ ^: ■■' - '■.; -: ■ -." - ^: - ^: \.

In the embodiment of Fig * 1 and 2 is. the inner ring 1 of the spherical bearing is provided on one end face with a neck 2 which has a circular outer surface 3 arranged eccentrically to the central bore of the ring.
