582,377. Securing parts on shafts. LAESSER, E. Sept. 27, 1944, No. 18491. Convention date, Sept. 27, 1943. [Class 80 (ii)] [Also in Group XXII] A device for clamping rotatable articles either internally or externally makes use of deformable conical discs. For securing articles 2 to a shaft 1, the gripping members 3 have rigid hubs 10 closely fitting the shaft and carrying conical discs 8 in opposed V-formation which terminate in cylindrical flanges 9 having end surfaces perpendicular to the shaft axis. On the application of axial pressure to the flanges 9 by means of a nut 7 screwing on the shaft and acting through spacers 4-6 against a collar 11 on the shaft, the flanges are expanded to grip the articles 2. Each member 3 may consist of two separate pieces abutting on a plane passing through the middle of the hub perpendicular to its axis. For securing a shaft 2<1>, Fig. 3, within a casing 1<1>, the member 3 has a rigid peripheral flange 10 and diverging conical discs 8 terminating in flanges 9 which grip the shaft when axial pressure is applied thereto by a screwed ring 7<1> and flanged discs 5<1>, 6<1>. In another form a rigid ring 10, Fig. 4, has outwardly and inwardly extending conical discs 8. 8<1> for causing the flanges 9, 9' to grip both outwardly and inwardly when axial pressure is applied by members 5, 6. The cylindrical surfaces of the flanges 9 &c. may be screw threaded or otherwise shaped to engage corresponding formations on the article gripped. The spacing members 4, 5 &c. may have the same diameter bore as the members 3 or a slightly less diameter. |
