Abstract
The invention relates to a machine, in particular a machine tool (9) for deep rolling wheelset shafts (5) for rail vehicle wheelsets with a headstock (12) and a tailstock (13) which each have prick punch points (16) for holding a wheelset shaft (5) at its respective ends, a device (16, 18, 20, 21 and 22) for driving the wheelset shaft (5), as well as tools which can be moved in directions (z, x) on the machine tool (9) for deep rolling lengthwise sections (axle zones 1 to 4) of the wheelset shaft (5), and clamping and feed devices. The tools consist of several pairs of work rollers (14, 15, 23, 25, 24, 26), of which each pair is intended for deep rolling at least one axle zone (1, 2, 3, 4) of the wheelset shaft (5).
Claims10
A machine, in particular a machine tool, for deep rolling wheelset shafts for rail vehicle wheelsets with two prick punch points for holding a wheelset shaft at its respective ends, a device for driving the wheelset shaft, two pairs of crankshaft deep rolling tools, which can be moved in directions x, y and z of the machine tool for machining the axle journal for the wheelset shaft, and with clamping and feed devices for the crankshaft deep rolling tools.
- Characterised by the fact that
- the crankshaft deep rolling tools consist of more than two pairs of work rollers (14, 15, 23, 25, 24, 26), of which
- each pair is intended for deep rolling at least one individual lengthwise section (axle zone 1, 2, 3, or 4) of the wheelset shaft (5).
