Deep rolling roller head of a deep rolling tool

Abstract

The invention relates to a deep rolling roller head (1) of a deep rolling tool for deep rolling radii or recesses (22) on the main and lifting bearing journals of crankshafts (21). Said deep rolling roller head is equipped with a housing (2) inside of which one or two laterally interspaced deep rolling rollers (4) are rotationally guided in a loose manner and with little play in two roller cages (5, 6). The roller cages (5, 6) are fastened to supports (15) on the face (3) of the housing (2) oriented toward the crankshaft (21). Said supports support the roller cages (5, 6) on their faces (10) oriented away from the deep rolling rollers (4) while laterally guiding them at the same time. The face (3) of the housing (2) oriented toward the crankshaft (21) is provided, on both ends thereof, with a projection (11, 12) for supporting each of the roller cages (5, 6). A fastening and guiding element (15) is provided for each roller cage (5, 6), engages inside the roller cage (5, 6), and can be fastened to one of the projections (11, 12) of the housing (2) at the same time.
