Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Jaw Crusher Tension Rod
Maintains contact between the toggle plate and seats and keeps the mechanism preloaded, preventing unseating during the return stroke.
Tension Rods (Tension Rod)— Jaw Crushers Wear part, position 12.
Location and Function
| Material Options | Quenched and tempered 40Cr or 42CrMo alloy steel, as specified in the OEM drawing |
| Typical Properties and Acceptance Criteria | The tension rod carries cyclic tensile loads and impact preload. Control yield strength, fatigue life, thread-root radii, straightness, decarburisation and surface defects. Rod material and mechanical properties must meet the specific OEM technical requirements. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
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.
