Motor speed and pulley diameter than the speed of the conversion ratio = output speed: speed = input load pulley pitch circle diameter: Motor pulley pitch circle diameter drogue drogue main TB QD cone sets of points, sleeve holes and pulley match at all It is half, and the two aperture drogue with two threaded holes on the pulley respectively form a complete bore, a threaded hole drogue another pupil with a 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 tightened, Bushes, the role of the screw thread on the cone pulley toward the small end of the pulley two screws, The two light cone sleeve hole is not completely processed through, so that when the bottom of the screw head against the light hole, it will force to the sleeve, sleeve with respect to the pulley to pulley taper The small end of the movement, this time because of the taper, spc Bushes, drogue have continued gripping the shaft 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. spa Bushes, Hengda Machinery (online consultation), Bushes provided by the Texas Hengda Machinery Co., Ltd.
