Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Gear Wheel / Bevel Ring Gear
Meshes with the pinion to drive the eccentric assembly and crusher head motion.
Gear Wheel / Bevel Ring Gear (Drive Gear)— Cone Crushers Wear part, position 18.
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 | Control gear material cleanliness, heat treatment distortion, case and core properties, tooth profile and lead, face and radial runout, cracks and contact pattern. Tooth contact pattern is a key factor in crusher gear reliability. Correct backlash and oil spray adjustment are also required during installation. |
| 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.
