Abstract:
1. A method of making a self-lubricating track roller, the method comprising: providing an inner ring having a radially outwardly facing surface; applying a parting agent onto the radially outwardly facing surface of the inner ring; applying a self-lubricating material over the radially outwardly facing surface of the inner ring; forming an outer ring around the self-lubricating material by wrapping resin soaked filaments around the self-lubricating material and the radially outwardly facing surface of the inner ring and curing the resin soaked filaments to form an outer ring having a radially outwardly facing surface and so that a radially inwardly facing surface of the outer ring bonds to the self-lubricating material, wherein one of the radially inwardly facing surface of the outer ring and the radially outwardly facing surface of the inner ring includes a radial groove formed between axially extending cylindrical surfaces of one of the outer ring and the inner ring, and the other of the radially inwardly facing surface of the outer ring and the radially outwardly facing surface of the inner ring have a radial ridge formed between axially extending cylindrical surfaces of the other of the outer ring and the inner ring, said radial ridge extending radially into the radial groove to resist axial forces acting on the outer ring and the inner ring, said radial groove and radial ridge being formed between the axially extending cylindrical surfaces of the inner and outer rings to resist radial forces acting on the outer ring and inner ring; and bonding a resilient tire onto a radially outwardly facing surface of the outer ring.
