Abstract
A milling machine for turning sets of wheels, especially railroad wheels, comprises at least one roller contacting the wheel circumference and at least one roller contacting the axially inwardly facing wheel surface for driving and/or supporting the wheels of a set. The circumferential roller and the inner roller for the same wheel are operatively supported by a common support such as a common housing whereby axial forces are taken up reliably so that axial excursions of the wheel set are prevented.
Claims9
A lathe machine for turning wheel sets having a common axis, comprising two groups of rollers, at least one roller group being provided for each wheel of a set, each roller group comprising first support roller means (6, 6') for contacting the circumference of one wheel of said wheel set, second roller means (30, 30') for contacting a wheel surface facing axially inwardly of said one wheel, said first and second roller means of a group being arranged in pairs, each pair comprising a wheel circumference contacting support roller and an axially inwardly facing wheel surface contacting roller, each roller group further comprising common support means (7, 32) for said first and second roller means, said common support means carrying the first and second roller means of a group with a rigid fixed relationship between the first and second roller means of a group so that all axial force components are taken up by said common support means and the wheel set is secured against axial displacement by short circuiting of these axial force components in each pair of rollers independently of the other pair.
