DESCRIPTION:
KOMATSU PC3000-1 HYDRAULIC MINING EXCAVATOR SERVICE REPAIR MANUAL (SN:PC3000-1-6202)
The combination of the high elasticity of its leaf springs with complimentary viscous damping by oil diSplacement, ensures that the GEISLINGER— COUPLING removes major critical speeds outside the engine speed range and dampens minor torsional vibrations effectively. The widest engine speed range free of vibration periods and dangerous reso- nance is thus obtained. Furthermore, employment of these couplings with their very dampening characteristics generally results in lower stresses in all engine driven shafts and gears as well as in the crankshaft permitting further power development on standard components. In any similar application, a simple vibration damper and/ or a pure flexible coupling would not confer the same advantages. The springs (3) together with the inner driving and outer driven member form chambers A and B which are filled with oil. If the outer member is displaced in relation to the inner member, the deflection of the leaf springs displaces oil from one chamber to the next, by this action the relative movements of the two members of the coupling are braked and the vi- brations are dampened.The spacers (8) limits the movement of the leaf springs.
