Maintains preload so the toggle mechanism stays correctly seated during the return stroke and under vibration.
Tension Springs (Tension Spring)— Jaw Crushers Wear part, position 13.
| Installation Position | Rear frame tension rod assembly, position 13 in the layout. |
| Main Function | Maintains preload so the toggle mechanism stays correctly seated during the return stroke and under vibration. |
| Replacement Frequency | Low replacement frequency; replace for changes in free length, cracks, corrosion, permanent deformation or inadequate preload. |
| Item | Details |
|---|---|
| Material Options | Heat-treated spring steel such as 60Si2Mn, as specified in the OEM drawing |
| Typical Properties and Acceptance Criteria | Control the elastic limit, cyclic fatigue performance, heat treatment uniformity, surface decarburisation, laps or cracks, and end-face squareness. Check the actual wire diameter, working travel, preload and hardness for the specific model, together with shot-peening and surface protection requirements. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
