Definitions

  • the invention relates to a rotation sleeve, a fastening connection assembly, a fastening connection structure and a mounting method for mechanically and statically coupling two or more objects, in particular to a material for fastening a connection with low hardness such as wood carpentry, etc. Stop sleeve, fastening connection assembly, fastening connection structure and installation method.
  • the reliability of the threaded connection is ensured by the self-locking of the friction of the thread pair and the friction between the contact faces of the thread pair.
  • the connecting thread has a certain self-locking property and does not automatically loosen under static load conditions.
  • the friction between the pairs of threads will disappear or decrease instantaneously; at the same time, in the case of high temperature or temperature changes, the material will creep and stress relaxation, and the friction will be reduced. Under multiple actions, the threaded connection is gradually released.
  • the threaded connections need to be tightened.
  • the connection force between the threaded connection pairs is mainly manifested by the static friction generated by the pre-tightening force when tightening the nut and the bolt. Therefore, for the threaded connection of key objects, the preload force must be controlled to ensure the reliability of the work. If the pre-tightening force is too large, the static load of the screw increases, and the strength of the threaded copy body is reduced. The pre-tightening force is too small and the work is not reliable.
  • the second is the failure of the threaded connection caused by common fatigue damage.
  • the threaded connection is subjected to an alternating load and the pre-tightening force in the connection causes the connection to be loose.
  • the cyclic alternating load acts on the bolts that are only connected, the bolts are fatigue cracked or even broken due to the large alternating stress. Fatigue failure usually occurs in areas where stress concentration is severe, such as: screw head, thread closing end, thread at the screw support plane, and transition corners of the screw.
  • the third is the creep that causes the threaded connection to fail at high temperatures.
  • Creep refers to the slow plastic deformation of a metal material over a long period of time under constant temperature and constant stress. Creep can occur at stresses that are less than the yield limit of the material. At low temperatures, the creep is not obvious, and only when a certain temperature (about 3/10 of the melting temperature of the material) is reached becomes significant. Creep can cause failure of the threaded connection at high temperatures. In order to eliminate creep, compensation measures are taken when the connection is assembled at room temperature, such as increasing the preload, or pre-tightening the bolts.
  • fretting wear causes failure of the threaded connection. Fretting wear is caused by a surface that is subjected to heavy loads and with little relative motion on the other surface. Threaded connections that carry vibration are most susceptible to fretting wear.
  • the failure mode of the above four main threaded connections is mainly due to the looseness of the thread due to the reduction of the pre-tightening force. Therefore, the anti-loose nature is to prevent the relative rotation of the thread pair (that is, the internal thread hole and Relative rotation between the externally threaded portions, such as relative rotation between the bolt and the nut.
  • Frictional anti-loose generally include the use of gaskets, self-locking nuts and double nuts. Frictional anti-loose is not reliable, and mechanical anti-loose methods are used for important threaded connections. Mechanical anti-loose and anti-loose anti-loose are called detachable anti-loose. Common mechanical anti-loose methods: the use of split pins, stop pads and string wire ropes.
  • Mechanical anti-loose mainly includes the following ways:
  • the pin hole can be drilled with a normal nut.
  • the disadvantage of this mechanical anti-loose method is that the first pin hole is drilled in the tail of the bolt, which affects the strength of the bolt; the second bolt cannot be too small, otherwise the pin hole cannot be drilled; thirdly, the groove on the nut needs to be opened. Pin fit, the width of the groove should not be too small, which greatly limits the number of slots on the nut.
  • the fourth structure is only suitable for the anti-loose between the bolt and the nut, and the case of connecting the parent body and the attached body with screws. Unusable or inconvenient to use;
  • the second is to use a round nut to stop the gasket to prevent loosening or to use a retaining gasket to prevent loosening.
  • the disadvantage of these two mechanical anti-loose methods is that the first need to machine the groove on the bolt or the shaft, which weakens the front degree of the bolt or the shaft; the second round nut stop washer needs to be thin to fold the outer tongue of the gasket Embedded in a groove of the nut, the outer tongue of the round nut stop washer can bear little force, and when the outer tongue of the gasket is subjected to a large shearing force from the nut, the outer tongue of the gasket is easily broken, thereby making the circle
  • the nut stop washer loses the anti-rotation effect, and the anti-rotation effect is not good; in the third disassembly, the outer tongue of the gasket needs to be folded again and kept in the same plane as the round nut stop washer, and the outer tongue of the gasket is deformed very much. It is difficult to achieve this requirement, so it is difficult to disassemble; when the fourth round nut stop washer is repeatedly used, the outer tongue of the gasket can be greatly reduced or broken due to repeated deformation
  • the third is to use a series of steel wire to prevent loosening.
  • the disadvantage of these two mechanical anti-loose methods is that more than two screws are needed to prevent loosening, and it is impossible to achieve the anti-looseness of the single bolt.

  • the shape of the ear is reversed, and the shape of the anti-retracting ear corresponds to the shape of the retaining groove, and the anti-retracting ear and the 0-ring can be fitted in the annular groove.
  • the utility model can prevent the front end nut from being retracted by the inner step of the anti-drop lever on the retaining sleeve, and the restraining nut is reversed, thereby reducing the screw connection failure caused by the nut reversal, and the thread connection is reliable.
  • the nut anti-loose structure of the structure is arranged when the back of the ferrule is aligned with the retaining groove of the retaining sleeve and the splitting cone of the splitter cone, and the ferrule is subjected to the force in the direction of the splitter cone, and the thrust is sufficient to cut off
