Full Technical Description
046 972 67 HUB, CLUTCH Positioned within the gear housing of the rock drill, this HUB, CLUTCH assembly connects the rotation motor to the gear train. Its primary function is to transmit torque, allowing the drill bit to turn effectively. It also serves a protective role, designed to slip under sudden, extreme torque loads, which prevents catastrophic damage to the rotation motor and gears if the drill string gets jammed.
A worn HUB, CLUTCH directly impacts drilling performance and rig availability. Symptoms of wear include a noticeable loss of rotation power, inconsistent turning speed under load, or the drifter struggling to break threaded rod joints. If the HUB, CLUTCH fails completely, rotation stops, bringing the entire drilling operation to a halt and requiring immediate, often difficult, field service.
During a drifter rebuild, always inspect the HUB, CLUTCH components for signs of glazing, heat damage, or excessive wear. If you hear a whining or grinding noise from the drifter during rotation, it could be an early warning of HUB, CLUTCH failure. Replacing the HUB, CLUTCH assembly with the correct part is essential for restoring performance and preventing more extensive damage.
