Anti Corrosion Thread Drill Coupling Sleeve For Underground Mining Drilling Tools

 

Coupling sleeve also called Coupling,when using rock drills with male shank adapters and a conventional drifter rod, a coupling is required to join the adapter to the rod,ensuring the ends touch for efficient energy transmission.

Couplings are also used to connect several rods to each other in the same way. Couplings have a middle stop to prevent over-threading on to the drill rod. We can manufactures semi-bridge, full bridge coupling sleeves for the percussive tools.

Function: Coupling sleeve,Adapter Coupling

Type: Full-bridge,Semi-bridge, same/different diameter coupling

Suitable for top hammers and drifter from Atlas Copco, Tamrock,Furukawa,Ingersoll Rand,etc.

Specification and function of the coupling sleeve:

Full-Bridge Coupling sleeve

Eliminates the potential for the coupling to creep along the threaded joints
Typically used in surface applications
Better uncoupling characteristics and tend to maintain tighter joints
Less chance of jamming
Best suited to machines equipped with independent rotation.

Semi-Bridge Coupling sleeve

Small non-threaded bridge in the center

Steel cannot thread past bridge area
Smaller diameter steel end portions fit together in the centre bridge area of the coupling
Semi-bridged couplings are most suited to high torque machines
Most rope and T threaded couplings are semi-bridged

Same diameter Coupling sleeve

Eliminates the potential for the coupling to creep along the threaded joints
Typically used in surface applications
Better uncoupling characteristics and tend to maintain tighter joints
Less chance of jamming
Best suited to machines equipped with independent rotation.
