FIELD: machine building. ^ SUBSTANCE: disconnectable clutch comprises first of all the first and the second parts of the clutch with means of transmission of a torque factor, and suggests for the preferred improvement of use, that the first part (3) of the clutch comprises protrusion (13) advancing along geometrical axis (2) of rotation, on the side surface of which the first circumferential groove (15) is made, and that the second part (4) of the clutch contains recess (16), aligned with recess (13) in its cross section, and on the side surface of which (17) the second circumferential groove (18) is made; that an annular elastically deformable retaining element (19) relative to the contour of an open or a closed perimetre, which is able to split the two parts of the clutch can be inserted into one or selectively to one of the circumferential grooves (18, 15), and the outer contour of which in divided state of the parts of the clutch (3, 4) outstands from the circumferential groove (18, 15). The invention also relates to the screw of the conveyor, and the helix (24) of the screw is attached to the shaft (25) of the screw which passes axially in the longitudinal direction, and the shaft (25) screw is connected to the second part (4) of the disconnectable clutch. ^ EFFECT: simplified installation and dismantling of the device, decreasing the time spent for assembly-disassembly. ^ 27 cl, 10 dwg |
