Summary

The taper sleeve is mainly divided into Taper Lock Bushing, QD Bushing and Split taper bushing. The holes where the taper sleeve and the pulley match are half-sided, and the two light holes on the taper sleeve and the two threaded holes on the pulley are respectively A complete hole is formed, and a threaded hole on the taper sleeve and a smooth hole on the pulley form a complete hole. When assembling, put the two screws in the two threaded holes of the pulley.

The Introduction Of Bushing

The taper sleeve is mainly divided into Taper Lock Bushing, QD Bushing and Split taper bushing. The holes where the taper sleeve and the pulley match are half-sided, and the two light holes on the taper sleeve and the two threaded holes on the pulley are respectively A complete hole is formed, and a threaded hole on the taper sleeve and a smooth hole on the pulley form a complete hole. When assembling, put the two screws in the two threaded holes of the pulley. As the screws are continuously tightened in the threaded holes on the pulley, the thread action pushes the screws to the small end of the tapered hole on the pulley, and the tapered sleeve The two light holes of the screw are not completely machined through, so that when the head of the screw touches the bottom of the light hole, the force is transmitted to the tapered sleeve, and the tapered sleeve moves relative to the pulley to the small end of the tapered hole of the pulley, At this time, because of the taper, the tapered sleeve will continue to wrap the shaft, and the shaft will react on the tapered sleeve and then on the pulley. In this way, the pulley, taper sleeve and shaft are tightly assembled together.

On the contrary, when disassembling, use a screw that is withdrawn from the threaded hole of the pulley in the threaded hole on the tapered sleeve.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.
