Articulated type connecting rod.

The connecting rod is the link that transmits forces between the piston and the crankshaft of reciprocating engine. Farm equipment cars and truck construction equipment and any other type of vehicle with an internal combustion engines uses some type of connecting rod. What is the basic function of a piston. The connecting rod is required to transmit the compressive and tensile forces from the piston and rotate at both ends.

In a radial engine the piston in one cylinder in each row is connected to the crankshaft by a master rod. Various methods have been devised for dealing with the effects of the articulated rod in aero engines. Four types of connecting rod assemblies. What engine requires a master and articulated connecting rod assembly.

The fork and blade connecting rod the master and articulated rod assembly. The intention is to design an articulated joint between a piston 1 and a connecting rod 4 of an internal combustion engine in which a fork shaped head of the connecting rod 4 surrounds a lug 2 projecting from the centre of the underside of the piston and holds a piston bolt 3 fitted in the lug 2 in a more compact manner than heretofore. In case of v type engines the bending moments progressively calculated from the gas and inertia forces of the two cylinders acting on one crankthrow are superposed according to phase. The plain type the fork and blade type the master and articulated type.

A connecting rod also called a con rod is the part of a piston engine which connects the piston to the crankshaft together with the crank the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The plain type connecting rod. Forged connecting rods are typed by the. They are primarily used for radial engines and on some v type engines.

This can be twice differentiated to give the acceleration. Different designs forked connecting rod articulated type connecting rod or adjacent connecting rods shall be taken into account. All other pistons in the row are connected to the master. Type designation and kind of engine in line engine or v type engine with adjacent connecting rods forked connecting rod or articulated type connecting rod operating and combustion method 2 stroke or 4 stroke cycle direct injection pre combustion chamber etc number of cylinders rated power kw rated engine speed r min.

Master and articulated rod assembly is used in radial engines articulated rods are constructed of forged steel alloy in either the i or h shape denoting the cross sectional shape. Fearn published in the journal of the royal aeronautical society 1927 a method is given which involves the representation of the piston displacement as a fourier series.
