BALANCER DEVICE OF RECIPROCATING ENGINE

PURPOSE:To reduce the imbalance synthetic force of a crankshaft by absorbing the variation of the peripheral length of a timing belt due to the eccentricity of a two-axis balancer by the eccentricity of an idle sprocket and driving the two-axis balancer by the timing belt. CONSTITUTION:A crank sproc...

Zusammenfassung:	PURPOSE:To reduce the imbalance synthetic force of a crankshaft by absorbing the variation of the peripheral length of a timing belt due to the eccentricity of a two-axis balancer by the eccentricity of an idle sprocket and driving the two-axis balancer by the timing belt. CONSTITUTION:A crank sprocket 10 is connected with a crankshaft, and balancer sprockets 16 and 18 are connected with each eccentric shaft of a two-axis balancer, and a timing belt 24 is laid onto the periphery. An idle sprocket 22 is installed onto the timing belt 24 in eccentricity so as to absorb the variation of the peripheral length L of the timing belt which is generated when the balancer sprockets 16 and 18 are set eccentric. Therefore, the high imbalance synthetic force of the crankshaft can be reduced markedly by the variation of the revolution of the balancer sprockets 16 and 18.
