wheel Loader Pin Shaft
Core function: Implement bucket articulation and motion transmission
Mechanical connection function: As a hinge axis between the bucket and components such as the boom and connecting rod, it rigidly connects the bucket body, rocker arm, and rod of the bucket to form a movable mechanical joint.
Action transmission hub: Driven by the hydraulic system of the loader, the pin shaft transmits torque through the hinge point, enabling the bucket to complete lifting, forward tilting, backward flipping and other actions, achieving material loading, transportation and unloading.
Repair and replacement scenarios
Original parts replacement: When the loader has been used for more than 2000 hours, if the fit clearance between the pin shaft and the shaft sleeve exceeds 0.3mm (standard clearance 0.02-0.08mm), it needs to be replaced as a whole to restore the accuracy of the bucket action.
Modification and Upgrade: Some users may choose thicker shaft sleeves (such as increasing wall thickness from 10mm to 12mm) to enhance their heavy load capacity, paired with high-strength pin shafts (increasing tensile strength by 20%)
Precautions for use (affecting the effectiveness of the intended use)
Overloading is prohibited: Under the rated load of LG855 bucket, the pin shaft bears a shear force of about 120kN. Overloading may cause the pin shaft to bend (allowable deformation ≤ 0.1mm).
Strict lubrication cycle: 30-50g of lubricating grease should be injected from the oil nozzle every 10 hours of operation. Lack of oil can cause dry wear of the shaft sleeve and pin shaft, accelerating wear (the wear rate can be increased by 5-8 times)
