In a known ring tension screws are provided as screws, whose head is sunk in the counter ring and whose thread is screwed into the adjusting ring. While dressing these lag screws pulls the threaded ring together and a force exerted by this in the axial direction is corresponding reduced.

The invention aims at a threaded ring with the aid of which an increase in a clamping force acting in the axial direction is achieved or such a force can be exerted. This goal is achieved according to the invention in that the screws in the outer ring serving as a counter ring are screwed in and on the outer ring serving as an adjusting ring on the counter ring Support facing side. The screws are designed as pressure screws, which when tightened the threaded ring Longer in the axial direction and thereby an increase in the ropes tensioned by unscrewing the threaded ring the resilience. In this way, parts arranged concentrically to the threaded ring can be clamped securely.

Further advantageous features emerge from the description and the claims together with the drawing. In this Is a threaded ring in connection with a milling cutter as an embodiment of the subject matter of the invention in longitudinal section • Chematieoh shown.

Shaft 1 has a collar 2. A milling cutter 3 is attached to shaft 1 between intermediate pieces 4 and 5. Calibration on the side facing away from the collar 2 side is a threaded part 6 on this threaded part is a through internally threaded Direction nut 8 is screwed, which has a lock ring 9 "• inen intermediate ring 10 and a collar. 11 Of the

Gewiaderiag can optionally also be provided with an external thread on its outside. The said rings are separated from one another by annular grooves 12 and 13, which are cut into the threaded ring 8 from opposing cylindrical surfaces and only have a narrow connection left between the rings 9 and 11, which is formed in cross section in the manner of a meander. In the threaded ring 8 are Pressure screws 16 arranged evenly distributed on a central circumference; The screws 16 are designed as grub screws, the threaded part of which is screwed to the counter ring 9 which pass through the intermediate ring 10 with play and are located on the side of the adjusting ring 11 adjacent to the counter ring 9 prop up. The threaded part of the screw 16 located in the counter ring 9 is advantageously followed by a support bolt penetrating the intermediate ring.

The parts 3 and 5 arranged coaxially to the threaded ring 8 are screwed onto the threaded part 6 of the shaft 1 braced under attachment to the federal government 2. By tightening the pressure screws 16, the position of the threaded ring 8 is secured by locking. At the same time, the threaded ring is pressed apart, so that there is an additional clamping force acting in the axial direction of the shaft 1. Are parts 3, 4.5 and

8 to one another without tension, a tension can be generated by tightening the pressure screws 16 in the threaded ring 8

Claims (3)
