Types of Crank Shaft

There are two types of crankshafts—side crankshaft and center crankshaft. The side crankshaft is also called the ‘overhung’ crankshaft. It has only one crank web and requires only two bearings for support. It is used in medium-size engines and large-size horizontal engines. The center crankshaft has two webs and three bearings for support. It is used in radial aircraft engines, stationary engines, and marine engines. It is more popular in automotive engines. Crankshafts are also classified as singlethrow and multi-throw crankshafts depending upon the number of crankpins used in the assembly. Crankshafts used in multi-cylinder engines have more than one crank pin. They are called multi-throw crankshafts.

Design of Centre Crankshaft

A crankshaft is subjected to bending and torsional moments due to the following three forces:
(i) Force exerted by the connecting rod on the crank pin.
(ii) Weight of flywheel (W) acting downward in the vertical direction.
(iii) Resultant belt tensions acting in the horizontal direction (P1 + P2).
In the design of the center crankshaft, two cases of the crank, positions are considered. They are as follows:
Case I The crank is at the top dead center position and subjected to maximum bending moment and no torsional moment.
Case II The crank is at an angle with the line of dead center positions and subjected to maximum torsional moment.
