Investigations on the Statical Strength of Solid Crankshafts (The 4th Report)

Abstract

In the 1st to 3rd reports, the authors investigated the effect of web dimensions and crankpin fillets on the statical bending and torsional strength and also the deflection of the webs by using single throw crankshaft models.Timoshenko and Gessner gave the equations, based upon the theory of continuous beam, to solve the multi-throw crankshaft on many supports. The authors have modified these equations from the results of the foregoing tests, and analyzed the experimental results of the four-throw crankshaft, described in the Report No.15 of the Shipbuilding Reserch Association of Japan.In the appendix, the results of the pure bending tests carried out on the single throw crankshafts used in the preceding tests are summarized.
