Technical Advice
Equipment and part identification, drawing review, material selection and manufacturing feasibility assessment.
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.
| Installation Position | Below the toggle mechanism, position 9 in the layout; works with the tension spring but is a separate part. |
| Main Function | Maintains contact between the toggle plate and seats and keeps the mechanism preloaded, preventing unseating during the return stroke. |
| Replacement Frequency | Low replacement frequency; replace immediately for thread damage, bending, corrosion or fatigue cracks. |
| Item | Details |
|---|---|
| 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 |
