and tooth spaces 26 according to an alternative method the sprocket body 20 is constructed according to the process described above in relation to fig1 a u2013 1c wherein the non circular flanges 40 a 40 b are fastened welded or otherwise connected to the hub portions 30 a 30 b respectively the finished sprocket body 20 including the non circular flanges 40 a 40 b can also be formed directly i e without first forming a blank and machining or otherwise working same according to advanced powdered metal forming techniques die casting and other methods known in the art it is not intended that the invention be limited to any particular method of forming the sprocket body 20 fig5 and 5a show the subject sprocket assembly 10 with the first and second circular cushion rings 60 a 60 b centered about the axis of rotation x the rings 60 a 60 b are loosely received in the respective grooves 42 a 42 b and float eccentrically relative to cylindrical surfaces 32 a 32 b the rings 60 a 60 b each define a central opening having a cylindrical within acceptable tolerances inner diameter dr wherein de 1 gt dr gt de 2 i e the inner diameter dr of the rings 60 a 60 b is larger than the minor diameter de 2 of flanges 40 a 40 b but smaller than the major diameter de 1 of flanges 40 a 40 b as shown in fig5 a when the rings 60 a 60 b are centered relative to axis of rotation x a portion of the flange peripheries 44 a 44 b overlap the rings 60 a 60 b to define a radial interference 11 that prevents the rings 60 a 60 b from moving axially outwardly.
