The Connection Method of the Shaft with the Pulley

  Bearing connection: If the drum shaft is fixed and does not rotate, the drum and the drum shaft can be connected using bearings, allowing the drum to roll on the drum shaft.

  Fixed Connection: If the drum shaft is chosen to rotate, then the drum and the drum shaft are connected in a fixed manner, which can be achieved using pins or welding.

  Expansion Sleeve Connection: A connection structure between a drive drum and a shaft, consisting of a drum and an expansion sleeve. The ends of the drum are welded with end plates, and a fixed sleeve is fixed at the center of the end plates. Both ends of the fixed sleeve are secured to the drive shaft through the expansion sleeve, which includes an inner sleeve and an outer sleeve that are nested together and connected by bolts.

  Key Connection: When installing the roller on the shaft, first install the key connection end, insert the key into the shaft, place the shaft in the pit, and simultaneously heat the roller to 200 degrees ° C. Lift the drum and proceed with installation; after the shaft and drum have cooled down, turn the shaft and drum over, insert them into the expansion sleeve, and finally install the circumferential tightening bolts. Use a torque wrench to tighten the bolts symmetrically. This is a keyless connection method that has been widely used in recent years.

  Clamp Connection: Utilizes sleeves and clamps to connect the wheel hub and axle, making installation simple and convenient.

  Tapered Connection: Utilizes the interlocking of the tapered surfaces on the hub and shaft to achieve connection, ensuring accurate positioning and reliable transmission.

  Diameter matching connection: Maximizes the lever effect between the wheel hub and the shaft, achieving a connection between the wheel hub and the shaft.
