Roller assembly for an undercarriage of a work machine

A roller assembly for an undercarriage of a work machine, comprising:

• a body member having (i) a passageway extending therethrough and (ii) a roller surface defined thereon;
• a first roller rim secured to said body member, said first roller rim having (i) a first inner side wall segment extending outwardly from said roller surface, (ii) a first outer side wall segment secured to said first inner side wall segment, said first outer side wall segment being positioned relative to an axis of rotation of said body member such that a first linear extension of said first outer side wall segment intersects said axis of rotation so as to define a first acute angle therebetween, and (iii) a first receptacle defined therein, said first receptacle having a first outer entrance and a first inner entrance, said first outer entrance is defined by a first edge having a first point, a second point, and a third point disposed thereon, said first point, said second point, and said third point defining a first plane;
• a first axle mounting arrangement positioned within said first receptacle such that no portion of said first axle mounting arrangement traverses said first plane;
• a second roller rim secured to said body member, said second roller rim having (i) a second inner side wall segment extending outwardly from said roller surface, (ii) a second outer side wall segment secured to said second inner side wall segment, said second outer side wall segment being positioned relative to said axis of rotation of said body member such that a second linear extension of said second outer side wall segment intersects said axis of rotation so as to define a second acute angle therebetween, and (iii) a second receptacle defined therein, said second receptacle having a second outer entrance and a second inner entrance, said second outer entrance is defined by a second edge having a fourth point, a fifth point, and a sixth point disposed thereon, said fourth point, said fifth point, and said sixth point defining a second plane;
• and
• a second axle mounting arrangement positioned within said second receptacle such that no portion of said second axle mounting arrangement traverses said second plane.

A work machine, comprising:

• a frame;
• a work implement mechanically coupled to said frame;
• and
• a roller assembly mechanically coupled to said frame, said roller assembly having (i) a body member, (ii) a passageway extending through said body member, (iii) a roller surface defined on said body member, (iv) a first roller rim secured to said body member, said first roller rim having (A) a first inner side wall segment extending outwardly from said roller surface, (B) a first outer side wall segment secured to said first inner side wall segment, said first outer side wall segment being positioned relative to an axis of rotation of said body member such that a linear extension of said first outer side wall segment intersects said axis of rotation so as to define an acute angle therebetween, and (C) a receptacle defined therein, said receptacle having an outer entrance and an inner entrance, said outer entrance is defined by a first edge having a first point, a second point, and a third point disposed thereon, said first point, said second point, and said third point defining a first plane, and (v) a first axle mounting arrangement positioned within said receptacle such that no portion of said first axle mounting arrangement traverses said first plane.
