[0002] The screw unloader is an important piece of port equipment used to unload bulk cargo (such as coal, ore, and grain) from ships. Its efficiency and stability are crucial to the operational efficiency of the port. In this equipment, the design and application of the vertical screw centering shaft alignment device plays a key role. The screw unloader uses the screw conveying principle to remove cargo from the ship's hold and transport it to a designated location through a conveying system. Its design mainly includes screw conveying components, centering shaft, and drive system. As the core component of the conveying system, the centering shaft is responsible for transmitting power to the screw device. Its alignment and stability directly affect the unloading efficiency and the wear of the equipment. Under high load and during operation, the existing device may experience vibration, uneven wear, or failure due to poor alignment of the centering shaft, thus affecting the smooth operation and service life of the equipment.
