Abstract
A tool is provided having two deep rolling work rollers ( ) made of a hard material which, for the deep rolling of grooves in crankshaft journals or crank pins, are arranged at a first mutual distance that corresponds to the specific width of the journals. Each of the work rollers ( ) is supported to float in a pocket-shaped recess ( ) provided in a cage ( ), in accordance with the first distance. The cage ( ) consists of a material which, compared to the material of the work rollers ( ), has a lower degree of hardness but superior sliding characteristics. The cage ( ) is located at the extreme end of the long leg ( ) of an L-shaped tool holder ( ), and has a second distance ( ) to a second cage for support of the same work rollers ( ). A minimum of one of the recesses ( ) of the second cage is configured in a way to provide the work roller ( ), at least in the direction of the first distance, with increased mobility, and in addition, a support surface is provided which engages the outer circumference of the work roller ( ).
