| 摘要 |
The invention concerns a tool having two deep rolling rollers (2) made of a hard material, which, for the deep rolling of the fillets on bearing journals or crank pins of crankshafts, have a first mutual interval from one another corresponding to the respective width of the journals. Each deep rolling roller (2) is mounted floating in a pocket-shaped.recess (14), which is provided in a cage (4) in correspondence with the first interval. The cage (4) consists of a material which is less hard than the material of the deep rolling roller (2) and has better gliding properties. The cage (4) is located at the outer end of the long leg (5) of an L- shaped tool holder (6) and has a second interval (8) to a second cage of the journal of the same deep rolling roller (2). At least one of the recesses (14) of the second cage is implemented in such a way that the deep rolling roller (2) has increased mobility at least in the direction of the first interval and, in addition, a support surface is provided which engages at the outer periphery of the deep rolling roller (2).
