Application

Used for fastening connections and power transmission shafting of jaw crusher components, ensuring assembly precision and operational reliability under alternating and impact loads.

Installation Notes

1. Before installation, check threads and mating surfaces for damage and apply anti-seize compound to threads; 2. Tighten bolts to the specified torque in the specified sequence, using a torque wrench and marking critical bolts; 3. For shaft parts, check concentricity and runout, and turn the assembly by hand to confirm no binding before operation.

FAQ

How to detect and correct bending deformation of the eccentric shaft?
Support both ends of the shaft on V-blocks and measure the radial runout of each journal with a dial indicator. Runout exceeding 0.05mm/m indicates bending. Slight bending can be corrected by cold pressing; if bending is large or surface cracks exist, replace the eccentric shaft.
In which cases must high-strength bolts be replaced?
Bolts must be completely replaced when thread damage, cracks, excessive elongation (usually exceeding 0.2% of original length), severe surface corrosion, or one overload fracture occurs. Never reuse high-strength bolts that have been overloaded.
What are the common causes of tie rod fracture?
Tie rod fracture is mostly caused by excessive spring tension, overload impact from tramp iron in the feed, thread fatigue damage, or wrong material. It is recommended to use 42CrMo quenched and tempered tie rods, regularly check spring tension, and install tramp iron protection.
