Taper sleeve is also called taper connecting sleeve, belt pulley taper sleeve, coupling taper sleeve, tightening sleeve, tightening cone sleeve, locking sleeve and locking shaft sleeve. Taper sleeve is a new type of commonly used mechanical transmission connecting part, which has the characteristics of high standardization, high precision, compact structure, convenient installation and disassembly. The taper sleeve is mainly used for the connection of belt pulley, sprocket and coupling.
The taper sleeve is mainly divided into TB taper sleeve, QD taper sleeve and STB taper sleeve. The holes at the matching part of the taper sleeve and the belt pulley are all half, and the two smooth holes on the taper sleeve and the two threaded holes on the belt pulley respectively form a complete hole. The one threaded hole on the taper sleeve and the one smooth hole on the belt pulley form a complete hole. During assembly, the two screws are placed in the two threaded holes of the belt pulley. As the screws are continuously tightened in the threaded holes on the belt pulley, the screw is pushed to the small end of the tapered hole on the belt pulley by the thread action, while the two light holes on the tapered sleeve are not completely processed. Thus, when the head of the screw abuts against the bottom of the light hole, the force is transmitted to the tapered sleeve, and the tapered sleeve moves toward the small end of the tapered hole on the belt pulley relative to the belt pulley, At this time, because of the taper, the taper sleeve constantly wraps the shaft, and the shaft reacts on the taper sleeve and then on the pulley. In this way, the pulley, cone sleeve and shaft are tightly assembled together.
