Drive Pulley (Drive Pulley)— Hammer Crusher Wear part, position 23.
| Installation Position | Large multi-groove pulley at the outer end of the rotor mainshaft, on the rear of the HDS; position 23 in the layout. |
| Main Function | Transmits torque through V-belts and maintains the designed speed ratio. |
| Replacement Frequency | Low replacement frequency; assess repair or replacement for excessive groove wear, cracks, a loose hub, excessive runout or loss of balance. |
| Item | Details |
|---|---|
| Material Options | Grey iron of the EN-GJL-250 type, ductile iron, cast steel or fabricated steel pulley; hub and locking assembly to the OEM design |
| Typical Properties and Acceptance Criteria | Check pulley material, casting defects and NDT, groove profile and pitch diameter, radial and face runout, hub fit, key or locking assembly, and static and dynamic balance. Groove wall wear changes belt seating and tension distribution. Cracks, eccentricity or imbalance impose additional loads on the bearings and mainshaft. |
| Principal Failure Mechanism | Impact, cutting and abrasion |
