THREAD CONNECTION OF PARTS Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in threaded connections of parts, such as parts of combustion chamber of gas turbine. Proposed connection contains two members interconnected by fastening element in form of bolt or screw in contact through thread with one of connection members. Fastening element is provided with ring groove behind member butt joint plane before thread providing shearing of fastening element after indicated plane of butt joint from side of other member. Groove can be made with intersection by butt joint plane. Non-round blind hole is made in fastening element from side of threaded end. Bottom of hole is located after groove. In case of jamming of thread, connection can be disassembled by applying torque to head exceeding bolt shearing torque in place of groove. After shearing of bolt of groove, connection can be disassembled and rest of bolt can be screwed out by wrench using the hole. EFFECT: possibility of disassembling the connection in case of jamming of thread and shearing of bolt. 2 cl, 1 dwg
