The invention relates to machine-building, in particular to demountable joints of machines and mechanisms. A sector assembled lock nut has a ring with inner conical opening and has sectors placed in the ring with external conical surface and inner threading for connection to bolt. According to the invention the sectors are made same. The sectors have positioned threading and slots for key installation, respectively. At that the sectors are installed symmetrically with gap between those. At that the sectors in assembled state are in tight contact with outer conical surfaces with inner conical surface of the ring and outer cylindrical surfaces with inner cylindrical surface of the ring placed at the side of the larger base of cone of the ring. The invention provides simplification of production of nuts, increase of reliability of threaded joint and integrity of assembled construction. |
