Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Gear Wheel
Meshes with the pinion and transfers drive torque to the eccentric assembly.
Gear Wheel (Gear)— Gyratory Crusher Wear part, position 08.
Location and Function
| Material Options | Quenched and tempered 42CrMo/50CrMo4 alloy steel or carburising steel such as 18CrNiMo7-6, according to the OEM gear pair design |
| Typical Properties and Acceptance Criteria | Material and heat treatment must be matched to the pinion. Quenched and tempered designs commonly balance tooth and core properties at around 280–360 HB; carburised designs may use a tooth surface around 58–62 HRC with a tough core. These specifications are not interchangeable between heat treatment routes. Verify material, forging grain flow, UT/MT, tooth profile and lead, runout, hardened case, contact pattern and backlash. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; 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.
