PCT No. PCT/DE90/00878 Sec. 371 Date Mar. 12, 1992 Sec. 102(e) Date Mar. 12, 1992 PCT Filed Nov. 15, 1990 PCT Pub. No. WO91/07600 PCT Pub. Date May 30, 1991.A taper clamping unit includes a tightening assembly having first and second taper rings, one of which is mounted on a cylindrical bushing. The cylindrical bushing has an end flange which extends opposite projecting portions of a plurality of screws which are used to connect, tighten, and untighten the first and second taper rings to each other. When the screws are loosened, the projections bear against the end flange such that the first and second taper rings are loosened from each other and when the screws are tightened, the projections bear against the first taper ring thereby tightening the first and second taper rings with respect to each other. |
