Chiaravalli – GE-T Couplings – Technical Appendix

Content
Appendix for GE‑T jaw couplings covering torque ratings, misalignment limits and spider hardness options for tailored torsional behavior.

Engineering

• Stiffness vs. Shore hardness and impact on resonance/settling times.
• Angular/parallel/axial misalignment envelopes per coupling size.
• Temperature and chemical exposure factors for elastomer selection.

Practical notes

• Align to within limits; set hub gap and spider pre-compression.
• Check key seating and hub inertia for start/stop duty.
• Re-inspect temperature and vibration after initial operation.
