Two-part nut with high pressing force

Abstract

The invention relates to a nut having an internal thread and two nut parts (1, 2), each of the nut parts (1, 2) having a section of the internal thread which is radially slidable onto an external thread (25), the nut parts (1, 2) having cooperating connecting elements which permit relative displacement of the nut parts (1, 2) in a direction extending radially with respect to the axis of the internal thread until reaching a use position in which the internal thread of the nut engages around the external thread (25) with a small clearance. The connecting elements have guide surfaces (9-20) which guide the nut parts (1, 2) of the nut in a rotational movement about an axis of rotation extending transversely to the axis of the internal thread when displaced into the use position, wherein each nut part (1, 2) has at least one first locking arm (5, 7) which has on one side a guide surface (9, 11) which induces the rotational movement when the nut parts (1, 2) are displaced and bears against a complementary guide surface (10, 12) on a second locking arm (6, 8) of the other nut part (1, 2). The nut has a plurality of pressure threads (36-41) which are arranged around the internal thread and receive the pressure screws (26-31) that can be screwed out in the axial direction from a first axial end face (21) of the nut and have a receiving means (35) for a screwing tool in the region of a second axial end face (22) of the nut, wherein at least one pressure thread (36, 39) is arranged in the first locking arm (5, 7), which has the first axial end face (21), and wherein the second locking arm (6, 8) with the second axial end face (22), which cooperates with the first locking arm (5, 7), has a recess (42, 43) through which the pressure screw (29, 26) projects.
