Z5 Type Locking Assembly(JB/T 7934‑1999)
Double‑cone‑ring heavy‑duty keyless shaft‑hub connection. Same taper angle for all conical rings, inner‑ring central flange for easy disassembly. Long mating surface, superior concentricity, highest load capacity in Z1‑Z5 series. 12.9‑grade hex socket clamping screws. Applied for metallurgy, mining, large conveyor, heavy gearbox.
Main Features
‑ Uniform taper angle for all conical rings
‑ Unique inner‑ring central flange for tool‑aided disassembly
‑ Long mating taper surfaces, excellent centering accuracy
‑ Large‑quantity 12.9‑grade high‑strength hexagon socket clamping screws
‑ Capable of transmitting ultra‑high torque and resisting torque‑axial combined loads
‑ Low radial run‑out after complete installation
‑ Non‑destructive assembly and disassembly, angle adjustable
‑ Over‑load slip function to safeguard expensive drive components
Recommended Tolerances
‑ Shaft：h7 / h8
‑ Hub bore：H7 / H8
‑ Mating surface roughness：Rz ≤16 μm
‑ Note: Z5 locking assembly has no gas‑tight sealing capability.
Application：
Heavy metallurgy equipment, mine main transmission, large‑size conveyor drums, heavy‑duty gearboxes, large general‑purpose machinery with extreme load requirements.
