Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Pinion
Transfers motor and drive shaft torque to the eccentric assembly gear.
Pinion (Pinion)— Cone Crushers Wear part, position 17.
Location and Function
| Material Options | Alloy steel such as 18CrNiMo7-6, 20CrMnTi or 42CrMo, with carburising or quenching and tempering as specified for the selected grade in the OEM drawing |
| Typical Properties and Acceptance Criteria | Tooth surface and core properties must match the heat treatment route. Carburised gears generally require a hard tooth surface and a tough core; quench-and-temper or induction-hardening routes depend on section size and load. Acceptance checks cover composition, hardened case, tooth profile and lead, runout, surface finish, magnetic particle inspection, contact pattern and backlash. Inspect the pinion and gear as a matched pair. |
| 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.
