ABSTRACT:
The clamping force adjusting device for a clamp device comprises a hollow housing (1) supported on a movable clamping part of the same, through which housing passes a rotatable and slidable tension rod (5), whose first end can be coupled to a force amplifier and whose second end (5b) carries a tension sleeve (6) fixed thereon. The tension sleeve (6) is supported on Belleville springs (9) through a thrust bearing (8) and an intermediate sleeve (b 10), the Belleville springs being supported directly in the housing (1). An adjusting sleeve (13) screws into a fine thread (14) of the housing (1) and has at its end facing the Belleville springs (9) a radially inwardly directed first stop shoulder (16), which cooperates with a radially outwardly directed second stop shoulder (17) of the intermediate sleeve (10) and/or a spacer ring (18) bearing on the thrust bearing (8).
