Vibration Characteristic Analysis of a Coupling System for Compound Biaxial and Inter-Shaft Bearings

Figure 2

Coupling system model of compound biaxial and inter-shaft bearing. The blue shaft is the inner shaft. The green shaft is the outer shaft. O is the mass centre of the item to be inspected. O₁ is the mass centre of the turntable. O₂ is the mass centre of the inter-shaft bearing. O₃ is the mass centre of rotary table bearing. O₄ is the mass centre of the inner shaft ball bearing. O₅ is the mass centre of the polyhedron.
