Balancingof Machines

Balancing of Machines, in mechanical engineering, means the elimination of stresses in the framework of machinery that are caused by the reciprocating motion of heavy parts or by the rotation of masses unsymmetrically disposed about the axes of rotation. Thus it is a general practice to place balance weights on the driving wheels of locomotives, these weights being calculated to neutralise, by their centrifugal force, the effect on the engine frame of the irregular motions of the connecting rod and crank. Balancing is of special importance in quick-speed engines, and affects their efficiency.
