Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Pinion Shaft Arm Liners
Protects the bottom shell arm and nearby pinionshaft housing structure from falling material wear.
Pinion Shaft Arm Liners (Pinionshaft Arm Liner)— Gyratory Crusher Wear part, position 26.
Location and Function
| Material Options | High-manganese steel, wear-resistant cast steel or quenched and tempered wear plate in the 360–500 HB range |
| Typical Properties and Acceptance Criteria | Withstands falling rock impacts and sliding abrasion in the discharge zone. Balance hardness, core toughness, resistance to cracking around holes and reliable fastening. Inspect remaining thickness, hole areas, vulnerable ends, clearance from the pinionshaft housing and bolt locking. Changes in material or thickness must not interfere with the drive shaft housing. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; sliding and three-body abrasion, local impact and cracking around fastener holes; gear tooth or pin-and-bushing wear, pitting, scuffing, uneven loading and fatigue |
Information Required for RFQ
- Equipment manufacturer, machine model, serial number, model details and latest drawing revision;
- Part dimensions, unit weight, key tolerances, assembly and fastening method;
- Current material, chemical composition, heat treatment, hardness and mechanical property reports;
- Processed material, maximum particle size, hardness/abrasiveness, moisture and tramp material records;
- Speed, load, temperature, pressure, process medium chemistry and continuous operating time;
- Failure photographs, wear measurements, crack/fracture locations and current service life;
Materials and values are for preliminary engineering selection. Final chemical composition, heat treatment, hardness and dimensional tolerances must follow the OEM drawings and technical agreement.
