Abstract

PURPOSE: To heighten the transmitted torque of a crankshaft, by shrinkage-fitting a journal with a steel ring whose thickness is prescribed as to the radius of the journal and whose yield stress is prescribed as to that of a web and by shrinkage-fitting the steel ring in the web.
CONSTITUTION: A journal 11 is shrinkage-fitted at A with a steel ring 12 whose thickness is not less than 10% of the radius of the journal 11 and whose yield stress is not less than 18% of that of a web 13. The shrinkage-fitted portion A is thus provided with double structure to increase the diameter of the journal 11. The journal 11 is then shrinkage-fitted at B in the shrinkage-fitting hole 14 of the web 13. In that case, the shrinking allowance of the shrinkage-fitted portion A is made larger than that of the other shrinkage-fitted portion B. This results in greatly heightening the transmitted torque of the shrinkage-fitted portion B and assuring similar transmitted torque in the other shrinkage-fitted portion A as well.
