| 摘要 |
The present invention relates to the deep rolling apparatus ( 8 ) of a deep rolling machine 1 for crankshafts ( 3 ) in which two arms ( 9, 10 ) across from each other support a deep rolling head ( 13 ) or a support roller head ( 14 ). The support roller head ( 14 ) has two support rollers ( 21, 22 ) with parallel axes and the deep rolling head ( 13 ) has two work rollers ( 23, 24 ) entering the radii or fillets of the main bearing or crank pin journals or journals of the crankshafts ( 3 ). In one embodiment of the deep rolling apparatus ( 8 ) in scissor-like construction an axial guide roller ( 27 ) is provided on the deep rolling head ( 13 ) and is centered relative to the deep rolling head ( 13 ), its axis of rotation being perpendicular to the axis of rotation of the crankshaft ( 3 ). The axial guide roller ( 27 ) has a diameter that is slightly smaller than the distance between two oil collars ( 25, 26 ) of a main crank pin journal ( 5 ) of the crankshaft.
