Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Meshes with the pinion and transfers drive torque to the eccentric assembly.
Gear Wheel (Gear)— Gyratory Crusher Wear part, position 08.
| Installation Position | Around the eccentric assembly, corresponding to location 08 in the FLS cutaway diagram marked on this site. |
| Main Function | Meshes with the pinion and transfers drive torque to the eccentric assembly. |
| Replacement Frequency | Low replacement frequency; assess the gear pair for pitting, spalling, scuffing, cracks, abnormal wear or an uneven contact pattern. |
| Item | Details |
|---|---|
| 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 |

ANRANST provides customers worldwide with engineering assessment, production at certified foundries to drawing, quality control and finished-part delivery for custom wear parts and industrial spares, with scope to support other custom industrial parts.
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Material grades and heat-treatment processes are specified order by order, confirmed in the technical agreement and tracked through production.
Drawing confirmation, material and process control, production tracking, inspection and acceptance coordination.
We coordinate manufacturing, quality confirmation, packaging and delivery of complete finished parts in a workable, closed-loop supply process.
Provide the existing model, drawings, drawing or part numbers, materials or operating conditions so we can identify the appropriate technical review and supply route.
