INVESTIGATION OF AXLE JOURNAL FILLETS AND DUST GUARD SURFACES RESULTING FROM CONTACT WITH JOURNAL BOX DUST GUARD FLANGES
In order to determine the extent to which damage was occurring with the dust guard opening in its present configuration, the Research Department made a field survey of axles coming into the wheel shop for attention. A total of 126 dust guard seats and fillets of axles were examined. During this examination it was observed that the following damage was occurring: 1. Pounding at the fillet, 2. Wear at the juncture of the fillet and dust guard seat diameter, 3. Grooving at the fillet caused by pressure on the dust guard seat diameter cold working the metal. As a result of damage to axle fillets by contact with dust guard wall surfaces, the Car Construction Committee reviewed the matter and decided that the dust guard wall projection should be modified to prevent damage to journals and also to provide better retention of oil in the journal box.
