Cone Pulley
Cone pulley, is a kind of in the installation of shaft and the pulley is embedded between a cone sleeve mechanical coupling assembly, which rely on the inner six angle screw self-locking leather
Belt wheel in the cone sleeve, sleeve shaft mounted on hold. It is compared with the ordinary straight hole type belt wheel, has many advantages: compact structure, does not need the axis positioning, convenient installation, cone sets only with different aperture, with a belt wheel can be applied to different shaft diameter, increase product versatility, allowing larger diameter tolerances, groove can be equipped with V band and narrow V belt etc.......
Cone pulley is a kind of Europe and the United States generally use mechanical transmission connection components, through 8 degrees and cone pulley inner cone compression connection, so that the centering precision transmission parts is greatly improved. Taper sleeve size series of standard design. The hole keyway according to standard ISO processing. Universal interchangeability is good, suitable for various occasions. When the drive parts after long time operation, inner hole and the chain slot may be damaged, if using the transmission sleeve, when this occurs, only need to replace the same taper sleeve can be restored using. Thus greatly improve the service life of transmission parts, reduce repair costs, save time.
Cone sleeve are mainly TB QD cone sleeve of cone sleeve, sleeve and the belt pulley mating hole is half of the cone sleeve, and the two light hole with two threaded holes wheels respectively form a complete hole, a screw hole on the taper sleeve and a light hole on the belt pulley to form a whole hole. In the assembly, the two screws on the two threaded holes of the belt pulley, along with the screws on pulley screw holes on the continue to tighten, thread screw to the small end of the pulley, and the two light hole taper sleeve is not entirely processing wear, so, when the screw the nail head against the light hole bottom, the force is transmitted to the taper sleeve, the taper sleeve is relative to the pulley to the belt pulley of the small end of the movement, then because the taper of the reasons, cone sets have been tightly wrap the shaft, and the shaft and counterproductive to the cone sleeve, and then act on the belt pulley. This belt pulley, taper sleeve and the shaft are tightly assembled together.
Conversely, when removing the screws, threaded hole in the exit from the belt pulley with taper sleeve threaded hole in a, in the process of tightening the screws, and towards the pulley of the small end of the direction of movement, when the screw head against the pulley light hole bottom, the force is transmitted to the the pulley, the pulley is relative to the sleeve to the belt pulley of the small end of the direction of movement, so, the belt pulley and the cone sleeve is separated from the sleeve, and also because of the loss from the belt pulley of the binding, the recovery point elastic circular degree, also with the shaft from.
When the sleeve belt wheel and the shaft are connected together, forming a tight fit connection. The cone sleeve hole and shaft are key links, is to transfer torque and force by bond. Cone and the belt wheel although no key connection, but there is a positive pressure joint surface, the friction force can transfer torque and force.
