<p>A hub and axle assembly having a bearing assembly (4) supported on a journal (3) of an axle beam (1) which has a screw threaded spindle (2) adjacent to the journal formed with a longitudinally extending keyway (6), has a hard faced washer (7) inside the hub (5) formed with through holes (9) and a key (8) to engage in the keyway. An adjusting nut (11) co-operates with the spindle (2) and has at least one hole (13), at least partially screw threaded, extending through it parallel to its rotational axis. The nut (11) receives and retains a securing screw (16) which can be engaged in any aligned one of the holes (9) in the washer (7). Bearing adjustment is made by tightening the adjusting nut against the washer, backing the nut off a pre-determined amount and then locking the adjustment by engaging the securing screw (16) in an aligned one of the holes (9) in the washer. Correct adjustment of the bearing assembly (4) can be achieved within the tolerance defined by the spacing of the holes in the washer, and the locking of the adjustment is possible without affecting the adjustment made.</p> |
