For the entire market, in fact, this sleeve pulley is not very common, but it is very wide range of applications. Compared to ordinary straight hole pulley, has many advantages: compact, no-axis positioning, easy to install, simply choose different aperture sleeve, with a pulley can be applied to different shaft, increase product Universal , allowing larger shaft diameter tolerances, geometry can be equipped with a V-belt and narrow V-belts and the like. Bushes are part of a new mechanical drive coupling widespread use of European countries by 8 givers cone pulley cone clamping coupling, so transmission parts centering accuracy is greatly improved. Drogue size series of standard design. Sleeve hole keyway pulley according to ISO standards process. Universal compatibility is very good, for a variety of occasions. When the drive member after a long run, the hole and chain groove damage may occur, if you are using this drive member drogue, when this happens, just replace drogue same specifications can be restored to use. Thus greatly improving transmission parts life, reduce maintenance costs, save time. Drogue drogue pulley on the main TB sleeve QD cone sets of points, bore sleeve with the pulley half of the match at all, and the two threaded holes two drogue and light hole on the pulley respectively, form a complete bore, a threaded hole with a tapered sleeve and pupil pulley formed a complete hole. When assembled, the two threaded holes in the pulley, with the screw in the threaded hole on the pulley continuously tighten the screws into the threaded action on the two screws on the cone pulleys the small end, and tapered sleeve Two pupil did not fully processed through, so that when the screw head against the bottom of the light hole, it will force to the sleeve, sleeve on the small end of the motion with respect to the pulley to pulley taper hole, this time because of the taper of the drogue have continued to pack the mandrel, and the shaft and counterproductive in the sleeve, and then acting on the pulley. Thus the pulley, sleeve and the shaft on tightly assembled together.
