Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Limits axial movement of the hammer shaft and prevents it from leaving the rotor.
Hammer Shaft Locking Device (Hammer Axle Retainer)— Hammer Crusher Wear part, position 03.
| Installation Position | At both ends of the hammer shaft, on the outer rotor discs or end plates; position 03 in the layout. |
| Main Function | Limits axial movement of the hammer shaft and prevents it from leaving the rotor. |
| Replacement Frequency | Medium replacement frequency. Inspect whenever hammers are changed; replace for cracks, hole or groove wear, deformation, thread damage or failure of the locking arrangement. |
| Item | Details |
|---|---|
| Material Options | Quenched and tempered 42CrMo/4140 alloy steel, high-strength locking discs or end plates, and OEM-specified fasteners |
| Typical Properties and Acceptance Criteria | Retainers withstand axial impacts, vibration and high-cycle fatigue. Check core toughness, hole and thread accuracy, contact faces, magnetic particle testing (MT), plastic deformation and locking features. Excessive strength or hardness combined with inadequate notch toughness can cause brittle fracture. Any design change requires verification of hammer shaft removal clearance and safe failure behaviour. |
| Principal Failure Mechanism | Impact, cutting and abrasion |
