Abstract
A kind of checknut, for the connection of link.The tooth form angle of screw thread is 90 °, and screw thread axial direction is axial force direction after screwed tight; Described 90 ° of screw threads are the combination of 60 ° of angles and 30 ° of angles; Described 60 ° of angles are the angle in the screw thread flank of tooth and diameter of thread direction; Described 30 ° of angles are the angle in another flank of tooth of screw thread and diameter of thread direction.The utility model 60 ° of large inclined-plane anti-loosing effects are good, and each worm tooth can on average bear work loads and axial force, effectively locking, substantially increases the working life of screw pair.
Description
Technical field
The utility model relates to thread technology field, and specifically a kind of tooth form is the checknut of 90 ° of angles.
Background technique
At present, conventional thread profile angle is generally 60 °.In work, stressed primarily of front two button worm tooths, anti-loosing effect is very poor, and can not reach fastening locking effect well, working life is short, screw thread premature failure, and finally cause connected piece to get loose too early, quality of product hidden danger is more.
Summary of the invention
For overcoming the deficiency of existing locking thread performance, goal of the invention of the present utility model is to provide a kind of checknut, to realize effective locking object.
For achieving the above object, the tooth form angle of the utility model screw thread is 90 °, and screw thread axial direction is axial force direction after screwed tight.
Described 90 ° of screw threads are the combination of 60 ° of angles and 30 ° of angles; Described 60 ° of angles are the angle in the screw thread flank of tooth and diameter of thread direction; Described 30 ° of angles are the angle in another flank of tooth of screw thread and diameter of thread direction.
Compared with prior art, 60 ° of large inclined-plane anti-loosing effects are good, and each worm tooth can on average bear work loads and axial force, effectively locking, substantially increases the working life of screw pair for the utility model.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model thread profile angle is 90 °, and screw thread axial direction is axial force direction after screwed tight.Described 90 ° of screw threads are the combination of 60 ° of angles and 30 ° of angles; Described 60 ° of angles are the angle in the screw thread flank of tooth 1 and diameter of thread direction; Described 30 ° of angles are the angle in another flank of tooth 2 of screw thread and diameter of thread direction.Bear the 60 ° of angles tightening rear axial force obviously to reduce relative to Impact direction slope, the amount of deformation of the Impact direction that same diametric amount of deformation is corresponding obviously increases, and is conducive to worm tooth and on average bears work loads.
After being threaded into, 60 ° of screw thread facings 3 are stressed, and the worm tooth of cooperation on average bears work loads and axial force.60 ° of screw thread facing 3 gradients are large, and the screw pair axial deflection be mated is little, effectively on average can bear work loads, and anti-loose ability strengthens greatly.
Claims (2)
