The Introduction Of Bushing
On the contrary, when disassembling, use a screw that is withdrawn from the threaded hole of the pulley in the threaded hole on the tapered sleeve. During the continuous tightening process, the screw also moves towards the small end of the tapered hole of the pulley. At the bottom of the light hole of the pulley, the force is transmitted to the pulley, and the pulley moves in the direction of the small end of the tapered hole of the pulley relative to the tapered sleeve. The binding force of the hole, plus a little elasticity to restore its own roundness, also disengages from the shaft.
When the tapered sleeve connects the pulley to the shaft, an interference fit connection is formed. The inner hole of the tapered sleeve is connected with the shaft by a key, and the torque and force are transmitted through the key. Although there is no key connection between the tapered sleeve and the pulley, there is positive pressure on the joint surface, and the generated friction force can transmit torque and force.
