What are the common faults of the bucket assembly - mechanical structure faults
Youdaoplaceholder0 Abnormal wear of bucket teeth and seat
Youdaoplaceholder0 phenomenon : The length of the bucket teeth is reduced by more than 30%, and the tooth seat plate is cracked or deformed
Youdaoplaceholder0 Cause : The impact of hard rock leads to the chipping of the 45MnB alloy steel bucket teeth, and the loosening of bolts accelerates wear
Youdaoplaceholder0 Measures : Replace the reinforced bucket teeth with an impact resistance of ≥150kJ and regularly check the bolt torque to 350N·m
Youdaoplaceholder0 The blade plate deforms and fails
Youdaoplaceholder0 phenomenon : The arc-shaped plate at the bottom of the bucket bends inward by more than 15°, and its thickness is reduced to less than 50% of the original value
Youdaoplaceholder0 Cause : Overloading operation and continuous erosion by materials lead to fatigue of 16Mn steel plates
Youdaoplaceholder0 measures : Weld HB500 grade wear-resistant liners and control the single loading quantity to be no more than 120% of the rated value
Youdaoplaceholder0 The hinge mechanism is stuck
Youdaoplaceholder0 phenomenon : The opening and closing Angle of the bucket is insufficient, accompanied by abnormal noises from metal friction
Youdaoplaceholder0 Cause : Poor lubrication of the pin shaft leads to sintering of the bearing, or deformation and loss of roundness of the hinge hole
Youdaoplaceholder0 Measures : Add lithium-based grease every 50 hours. Deformed pin shafts should be replaced with 148-3307 type reinforcing parts
