Description
Technical field
The utility model relates to machanical fastener technical fields, are a kind of screw thread groups of different screw pitch fastenings specifically
Part.
Background technique
Conventional threaded anti-loosing structure generallys use following methods at present:
1. widely used is that friction is locking, apply the normal pressure not changed with external force between screw thread pair, generation can be with
The frictional force for preventing screw thread pair from relatively rotating, by axial or simultaneously two realized to compressions, such as using elastic washer, double spiral shells
Female, self-locking nut and nylon inserts locking nut etc..Which is more convenient for the disassembly of nut, but in shock and vibration and
The case where alternating load, screw thread pair can cause pretightning force to decline because of relaxation, and with the increase of vibration number, pretightning force will be slow ground
Reduce, eventually lead to nut loosen, thread connection failure.
2. locking machinery is the relative rotation for directly limiting screw thread pair using retainer, such as using split pin, series winding steel wire
With locking plate etc., it is inconvenient that this mode will cause disassembly, and needs that screw thread pair is further processed, and such as drills.
3. riveting rush it is locking be made after tightening using rushing the methods of point, welding, bonding screw thread pair lose movement sub-attribute and
It is connected to become non-disconnectable connection, in this way, screw thread pair is used only once, and is dismantled very difficult, it is necessary to destroy spiral shell
Line pair can be dismantled.
4. being designed using unconventional thread form, increasing the difficulty of processing of screw thread or needing special process tool.
5. increasing ratchet using in nut end face, tightening screw thread makes ratchet be pierced into workpiece surface, achievees the purpose that locking, adopts
Workpiece surface can be destroyed with such mode.
In conclusion needing a kind of fastening structure that can be anti-loosening, convenient for disassembly and assembly.
