There are TB drogue drogue QD cone sets of points, matching sleeve with the pulley hole is half, and the two aperture drogue with two threaded holes on the pulley respectively form a complete hole, a threaded hole drogue another pupil with a pulley formed a complete bore. When assembling large Bushes, two threaded holes in the pulley, with the screw in the threaded hole on the pulley continuously tighten the screws into the threaded effect on the cone pulley belt pulley on the small end of the two screws, The two light cone sleeve hole is not completely processed through, so spz Bushes, when the bottom of the screw head against the light hole, it will force to the sleeve, sleeve with respect to the pulley to the small end of the cone pulley movement Bushes, then because of the taper of the drogue will continue gripping the shaft Bushes manufacturers offer, 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. 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. Its inner hole keyway according to ISO standard processing. Universal compatibility is very good, for a variety of occasions. Spz Bushes, Zhejiang Bushes, provided by the Texas Hengda Hengda Machinery Machinery Co. Texas Hengda Machinery Co., Ltd. (www.sddzhdjx.com) (www.sddzhdjx.com) strong, credible, in Dezhou machining industry has accumulated a large number of loyal customers.
