In the paper, the measurement of the marine diesel engine crankshaft residual stresses is presented. The hole
drilling strain gauge was chosen because of its simplicity and low cost. Moreover, deflection calculation was made for
the load corresponding to its weight and the concentrated force in the chosen bearing conditions. Deflection of the
journal and bending rigidity under the concentrated force was calculated as well. In that case, the crankshaft was
supported in the neighbouring crank journals. The reduced stresses were calculated according to the Huber – Mises
hypothesis. The residual stresses were measured in the marine diesel engine crankshaft type 12V38 after the finishing,
with the hole-drilling method. It was found that the residual stresses reach the maximal value of 86 MPa, but for 50%
of measuring points, the residual stresses did not exceed the value of 20 MPa. The squeezing stresses were found to be
dominant. The measurement results provided important data for further consideration, especially for the correction of
the bending deformation of the produced crankshaft.
