Definitions

  • the invention relates to an anti-loose washer used as a fastener. Background technique
  • the anti-bolt loose washers currently in use mainly include GB93-97 standard spring washers, GB861.1-87 internal tooth lock washers, etc. They have the disadvantage that the anti-loosing performance needs to be further improved, among which spring washers are not stressed. Balanced, internal toothed lock washers should not be used for weaker materials and should not be removed often. Summary of invention
  • the object of the present invention is to provide an anti-loosing washer with better anti-loosing performance, balanced force, not restricted by weaker materials, and which can be frequently disassembled.
  • the inner circle has internal teeth, the internal teeth are radially extended and axially lifted, and the inner diameter formed by the expansion under pressure is smaller than the outer diameter of the bolt, and is forced to be clamped radially On the bolt.
  • At least two uniformly distributed internal warped teeth also have the same helix angle as the mating bolt thread, and the inner diameter formed by the expansion under pressure is smaller than the outer diameter of the bolt thread groove, and is forced. Snap into the thread groove.
  • the produced incisor teeth can also be made elastic.
  • Two to multiple washers are stacked in the same direction. It has the performance of a combination of a self-tightening nut and a spring washer. There may also be appropriate spacing between the internally raised teeth. It is also possible to make stop lugs on the outside of the washer.
  • uniformly distributed radially-outwardly raised and axially warped internally warped teeth have both axial elasticity and overcome the uneven force of the spring washer, while increasing Radial clamping on bolts or thread grooves provides more effective anti-loosening performance. Radial clamping on bolts also overcomes the disadvantages of internal toothed lock washers that are not suitable for weak materials and should not be dismantled often.
  • One piece of the anti-loosening washer of the present invention has the functions of flat, spring, and internal tooth locks, and saves the occupied space, especially when two or more pieces are stacked in the same direction, which overcomes the spring and internal tooth locks.
  • Tight washers are not suitable for stacking, and have the performance of the combination of self-tightening nuts and spring washers. This is a feature not available in other anti-loosening washers.

  • FIG. 12 is a development view at H in FIG. 10. Detailed description of the preferred embodiment
  • a kind of anti-loosening washer as shown in Figure 1, Figure 2, and Figure 3 The internally tilted teeth that are raised in the same direction in the axial direction are elastic.
  • the central hole formed by the internally tilted teeth under pressure must be smaller than the outer diameter of the bolt, and is forced to be clamped radially on the bolt, which is relatively non-rotatable with the bolt. At the same time, it has axial elastic stress to achieve a more reliable anti-loose effect.
  • Figures 4, 5, and 6 show the anti-loosening washer with the helix angle of the internal warpage teeth.
  • the uniformly distributed internal warpage teeth that extend radially and rise in the same direction in the axial direction are elastic and have the same thread as the mating bolts.
  • the central hole formed by the internally tilted teeth under pressure must be smaller than the minimum outer diameter of the thread, and is forced to be clamped radially in the thread groove, and will not be caught on the thread.
  • it has the combination performance of self-tightening nut and spring washer.
  • tooth-shaped anti-loose washer As shown in Figures 7, 8, and 9, there is another tooth-shaped anti-loose washer.
  • the internal warped teeth also have a certain internal tooth lock washer performance after compression and expansion.
  • This tooth profile may also have the same helix angle as the mating thread.
  • Figure 10 Figure 10 and Figure 12 show another toothed anti-loose washer. This form is conducive to increasing strength and is suitable for matching with countersunk bolts. Industrial applicability
  • the anti-loosing washer of the present invention has the functions of flat, spring and internal tooth lock at the same time, saves the occupied space, has a reliable anti-loosening effect, is convenient for frequent disassembly, and is simpler to manufacture.

Abstract

L'invention concerne une garniture de joint de calage comprenant un segment de corps annulaire et une pluralité de dents internes disposées sur le bord interne du segment de corps annulaire. Cette garniture de joint est caractérisée en ce que lesdites dents internes s'étendent radialement vers l'intérieur et se dressent axialement. Sous la pression exercée, le diamètre interne des dents est inférieur au diamètre externe du boulon et les dents sont plaquées radialement contre le filetage du boulon.
