Steel double chain cone roller:

The taper sleeve is a new type of mechanical transmission coupling part commonly used in European and American countries. It has the characteristics of high standardization, high precision, compact structure, and convenient installation and disassembly. The 8 degree outer cone surface is tightly connected with the inner cone surface of the pulley, sprocket and other transmission parts to greatly improve the centering accuracy of various transmission parts. The size of the cone sleeve is a series standard design. The keyway of the inner hole is processed according to ISO standard. Universal interchangeability is very good, suitable for various occasions. When the transmission parts run for a long time, the inner hole and the chain groove may be damaged. If it is a transmission part using this kind of taper sleeve, only need to be replaced when this happens The cone sleeve of the same specification can be used again. Therefore, the service life of transmission parts is greatly improved, maintenance costs are reduced, and time is saved.

The taper sleeve is mainly divided into TB taper sleeve, QD taper sleeve and STB taper sleeve. The holes where the taper sleeve matches the pulley are half-sided, and the two smooth 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, place 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 threads will push the screws to the small end of the tapered hole on the pulley, and the tapered sleeve The two light holes are not completely processed, so that when the head of the screw presses against the bottom of the light hole, the force is transmitted to the taper sleeve, and the taper sleeve moves to the small end of the taper hole of the pulley relative to the pulley. At this time, because of the taper, the taper sleeve continuously wraps the shaft, and the shaft reacts to the taper sleeve and then acts on the pulley. In this way, the pulley, taper sleeve and shaft are tightly assembled together.
