Threaded connection details

 

A threaded connection is used to connect large parts. The device includes a bolt having a smooth cylindrical section and a threaded section of smaller diameter, connected smooth conical section, a nut, screw on the threaded section of the bolt, and a sleeve having a tapered internal surface corresponding to the conical surface of the bolt and installed between the nut and one of the joined parts. Eye bolts are removable in the form of two half-rings, covering their sleeve and Circlip. On the inner surface of the half-rings are made ledges, and on the smooth cylindrical surface of the bolt in response to them depression. The technical result is to reduce the complexity of the disassembly of threaded connections. 1 Il.

The invention relates to mechanical engineering and can be used for the connection of large parts, such as directing beams of the mechanism for moving drilling rigs, well drilling oil and gas wells.

Known threaded connection, installed in the containing part holes bolt having a cylindrical section and mated with him conical section located in koottam this connection is the inability to align the holes of the details of the force coil pair, what complicates the docking of large parts.

The closest to the essential features of the claimed invention is a threaded connection, installed in the containing part holes bolt having a smooth cylindrical section and a threaded section of smaller diameter, connected smooth conical section, and a nut, screw on the threaded section of the bolt. Between the nut and one of the joined parts installed sleeve having a tapered internal surface corresponding to the conical surface of the bolt (see ed. St. USSR 872807).

The disadvantage of the invention is the high complexity of dismantling threaded connection.

The present invention is directed to solving the problem of reducing the complexity of the disassembly of threaded connections.

The problem is solved by creating a threaded connection, installed in the containing part holes bolt having a smooth cylindrical section and a threaded section of smaller diameter, connected smooth conical section, a nut, screw on the threaded section of the bolt, and a sleeve having a tapered internal surface corresponding to the conical surface of the bolt and ustanovlenno in the form of two half-rings, covering their sleeve and Circlip on the inner surface of the half rings are made ledges, and on the smooth cylindrical surface of the bolt return it hollows.

Due to the fact that the bolt head is detachable, the break-up of the connection is greatly reduced, as is enough to remove the retaining ring and covering half sleeve, you don't need to make great efforts for screwing nuts.

For a better understanding of the invention shown the drawing, which shows a threaded connection in the section.

A threaded connection includes a bolt 1, a conical part which is installed sleeve 2, and the threaded section - nut 3. On the smooth cylindrical surface of the bolt is made a groove in which is placed the tabs semirings 4 having a flange that covers half sleeve 5.

The retaining ring 6 records against axial movement of the sleeve 5. Connect parts 7 are located on the smooth cylindrical section of the bolt 1.

The dismantling of the connection is as follows. Removed the retaining ring 6, the sleeve 5, the ring 4, and then bolt out of the connection.

Thus, thanks to the removable head of the bolt is facilitated by Italy, contains mounted in the holes in the parts bolt with removable head having a smooth cylindrical section and a threaded section of smaller diameter, connected smooth conical section, a nut, screw on the threaded section of the bolt, and a sleeve having a tapered internal surface corresponding to the conical surface of the bolt and installed between the nut and one of the joined parts, characterized in that the removable bolt head is made in the form of two half-rings, covering their sleeve and Circlip on the inner surface of the half-rings are made ledges, and on the smooth cylindrical surface of the bolt in response to them depression.
