The cone sleeve is mainly divided into TB cone sleeve, QD cone sleeve, and STB cone sleeve. The holes where the cone sleeve matches the pulley are all half sided, and the two smooth holes on the cone sleeve and the two threaded holes on the pulley respectively form a complete hole. One threaded hole on the cone sleeve and one smooth hole on the pulley form a complete hole. During assembly, two screws are installed in the two threaded holes of the pulley. As the screws are continuously tightened in the threaded holes of the pulley, the thread action pushes the screws towards the small end of the tapered hole on the pulley. However, the two smooth holes on the conical sleeve are not fully machined through. Therefore, when the head of the screw presses against the bottom of the smooth hole, force is transmitted to the conical sleeve, and the conical sleeve moves relative to the small end of the tapered hole on the pulley, At this point, due to the taper, the cone sleeve continuously wraps around the shaft, which in turn acts on the cone sleeve and then on the pulley. In this way, the pulley, cone sleeve, and shaft are tightly assembled together.

On the contrary, during disassembly, the screw that exits from the threaded hole of the pulley is inserted into a threaded hole on the cone sleeve. During the continuous tightening process, the screw also moves towards the small end of the pulley cone hole. When the screw head presses against the bottom of the pulley cone hole, the force is transmitted to the pulley. At this time, the pulley moves towards the small end of the pulley cone hole relative to the cone sleeve, causing the pulley to detach from the cone sleeve, And the cone sleeve also detached from the shaft due to the loss of the constraint force from the pulley cone hole and the slight elasticity of its own restoration of roundness.
When the taper sleeve connects the belt pulley with the shaft, a interference fit connector is formed. The inner hole of the cone sleeve is connected to the shaft with a key, which transmits torque and force through the key. Although there is no key connection between the cone sleeve and the pulley, there is positive pressure on the joint surface, and the friction generated can transmit torque and force.
The representation method of the cone sleeve:
For example: 1210-25 (1210: type of cone sleeve 25: aperture of 25MM)
