Tool revolver

A tool turret with a turret head (12) supported by a housing (20) and rotatable relative to this housing (20) by way of at least one axial bearing (24), which turret head (12) has on the side facing the interior of the housing a gear rim (29) concentric by its axis of rotation (26) with gears extending radially which are in alignment with the teeth of a gear rim (30) in optional rotary positions of the turret head (12) of the housing (20), and with a gear rim (34) movable by means of a locking element (32) under fluid pressure in the direction of the axis of rotation (26) of the turret head (12), the radial teeth of which gear rim (34) mesh in the locking position under the force generated by way of the fluid pressure both with the gear rim (28) of the turret head (12) and with the gear rim (30) of the housing (20), the hydraulic pressure simultaneously applying to the turret head (12), by way of a connecting element (38), an axial reaction force which is opposite the axial force exerted by the locking element (32) on the gear rim (28) of the turret head (12), characterized in that the axial bearing (24) is mounted between turret head (12) and housing (20) in the direction of the turret head (12) upstream from the locking element (32), in that the hydraulic medium generating the fluid pressure may be introduced between the locking element (32) and the connecting element (38), and in that the connecting element (38) engages the locking element (32) from below in such a way that the axial bearing (24) is subjected to a pressure load when the turret head (12) is in both the locked and the unlocked state.
