Manufacture of Doxford crankshafts 1

Abstract

The paper deals with the history and development of the shaft from the original Doxford opposed piston engine. It then deals progressively with the materials used, some methods of heat treatment, as well as the preparation of the parts previous to shrinking. The actual shrinking process is also described as well as the final machining and the subsequent crankshaft assembly. Drawings covering the sequences are included. In finality, conclusions are drawn and the consideration of future prospects and methods are also discussed.
