Spherical plain bearing with angular misalignment restraint system, and angular misalignment restrain system

A spherical plain bearing comprising:

• an outer ring having an outer ring first axial end, an outer ring second axial end opposite to the outer ring first axial end, and a concave interior spherical surface extending between the outer ring first axial end and the outer ring second axial end;
• an inner member having an inner member first axial end, an inner member second axial end opposite to the inner member first axial end and a convex exterior spherical surface between the inner member first axial end and the inner member second axial end, the inner member being pivotally disposed at least partially in the outer ring such that the inner member and the outer ring are angularly misalignable relative to one another;
• and
• an angular misalignment restraint system which includes an inner member restraint feature on the inner member and an outer ring restraint feature on the outer member,
• wherein a first portion of the inner member restrain feature is spaced apart from a second portion of the outer ring restraint feature when the inner member and the outer ring are angularly misaligned relative to one another by less than a predetermined maximum angle θ,
• wherein the first portion of the inner member restrain feature is shaped and arranged to come into abutment with the second portion of the outer ring restraint feature when the inner member and the outer ring are angularly misaligned relative to one another by the predetermined maximum angle θ, and
• wherein the abutment prevents any further angular misalignment of the inner member relative to the outer ring.
