How to design a crankshaft?
CRANKSHAFT DESIGN PROCEDURE
Basic engine details like bore, stroke, engine configuration, compression ratio, bore centre distance and connecting rod length will decide the basic shape of the crankshaft and one can able to decide the crankpin and main journal locations..
What are the criteria for the design of crankshaft?
The crankshaft design is based on an evaluation of safety against crankshaft fatigue in highly stressed areas.
The crankshaft analysis is also based on the assumption that the areas exposed to the highest stresses are: fillet transitions between the crankpin and web as well as between the journal and web..
What are the design considerations for the crankshaft?
CRANKSHAFT DESIGN PROCEDURE
Basic engine details like bore, stroke, engine configuration, compression ratio, bore centre distance and connecting rod length will decide the basic shape of the crankshaft and one can able to decide the crankpin and main journal locations..
What is designed into the crankshaft?
What is designed into the crankshaft to provide for engine balancing? counterweights..
What is the design of the crankshaft?
A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin or ("conrod") journals.
The two-plane V8 crankshaft pictured in Figure 1 has five main journals and four conrod journals, each spaced 90\xb0 from its neigbors..
What is the process of making a crankshaft?
There are three widely adopted methods of manufacturing crankshafts: casting, forging, billet machined; of these forging is considered to be the best manufacturing process for crankshafts considering strength aspects.
Conventional crankshaft manufacturing processes by forging involves forging followed by machining..
- Most modern crankshafts are located in the engine block.
They are made from steel or cast iron, using either a forging, casting or machining process. - There are mainly three processes which are used for crankshaft manufacturing for metals: forging, casting, and machining.
Forging is nothing but shaping of metal by plastic deformation.
There are three typical stages of crankshaft forging.
