A Forged Crankshaft And A Process Of Making It
Abstract: The weight of the crankshaft is among the many factors that adversely influence the engine performance. Reducing the weight of the crankshaft without affecting its strength and balancing characteristics would improve the engine performance. The present invention provides a crankshaft and the process of manufacturing it such that its weight is reduced at least by 5-10% than conventionally manufactured crankshafts of comparable specification. This is achieved by reducing machining allowance which is provided during forging design, such that it does not adversely impact its strength and balancing ability. Moreover the additional aspect of kidney pocket inclusion into combined area of web and counterweight profile reduces weight of crankshaft further at least 5%. A reduction in total machined area of the webs is also another aspect of the present invention. Figure 3B is a typical representation of the invention.
