ECCENTRIC ROCKING TYPE REDUCTION GEAR

A crankshaft (3) has eccentric holes (36, 37) communicating with each other. The eccentric hole (36) extends in the axial direction of the crankshaft (3) from one end surface of the crankshaft (3) and is disposed so as to be eccentric in the same direction as a cam section (31). The eccentric hole (...

Beschreibung
Zusammenfassung:	A crankshaft (3) has eccentric holes (36, 37) communicating with each other. The eccentric hole (36) extends in the axial direction of the crankshaft (3) from one end surface of the crankshaft (3) and is disposed so as to be eccentric in the same direction as a cam section (31). The eccentric hole (37) extends in the axial direction of the crankshaft (3) from the other end surface of the crankshaft (3) and is disposed so as to be eccentric in the direction of the eccentricity of a cam section (32). A centrifugal force due to the rotation of the crankshaft (3) generates a force couple about an axis which is perpendicular to the axis of the crankshaft (3). The force couple is reduced by the eccentric holes (36, 37). The cam sections (31, 32) are arranged around the axis (a1) of rotation with the phases shifted by 180 degrees from each other. As a result, a translational force acting in the direction perpendicular to the axis of the crankshaft (3) is also reduced.
