Abstract
The utility model discloses a faced washer, wherein, an anti-loosening wing piece is evenly arranged along the circumference of an outer circle, and anti-loosening positioning teeth is arranged on the side face of an inner circle. When the utility model is used, the anti-loosening positioning teeth is connected with a screw bolt or a workpiece, the anti-loosening wing piece is tightly held with a screw nut or a screw bolt head so as to prevent a screw thread connection from loosening. The utility model overcomes the defects that a faced washer has a poor effect of anti-loosening and a spring washer is easy to break.
Description
The utility model relates to a kind of mechanical links, specifically belongs to a kind of anti-loosening faced washer.
At present, the packing ring that mechanically uses has plane gesture circle and spring washer.The spring washer material requires high than faced washer, price is expensive.Have the more use spring washer of mechanical motion vibration environment condition, but often occurring phenomenon of rupture in the spring washer using process.Under this environmental conditions, it is loosening that faced washer and being threaded is prone to.
The purpose of this utility model is to provide a kind of locking wing that has, and the novel planar packing ring of locking locating tooth is to overcome the deficiency of above-mentioned two kinds of packing rings.
The technical solution of the utility model is: evenly be provided with 2～10 locking wings in faced washer cylindrical side along the circle direction, 1～2 locking locating tooth is established in the circle side in the faced washer.During use, link by locking locating tooth and bolt or workpiece, the locking wing hugs nut or bolt head, and is loosening to realize preventing scyewed joint.

Fig. 5 locking washer B user mode figure
Embodiment 1 is shown in Fig. 1,4, and workpiece through-hole connects.
The locking wing (3) that side, locking washer faced washer outer ring (1) along the circumferential direction evenly is provided with is 8, and the locking locating tooth (4) of 2 symmetries is established in interior circle (2) side, and locking locating tooth (4) and packing ring annulus (5) are in same plane.During use, bolt (6) axially grooved (7), the locking locating tooth (4) of locking washer (8) falls into groove (7), treat nut (9) with workpiece fastening after, the locking wing (3) is dug 90 ° nut (9) is embraced.Therefore, nut (9) can not become flexible when Workpiece vibration.
Embodiment 2, and shown in Fig. 2,3,5, the workpiece non through hole connects
The locking wing (3) is 8, and 2 locking locating tooths of symmetry (10) are vertical with packing ring annulus (5).Last through hole workpiece (11) and packing ring (14) surface of contact, positioning hole (12) is offered in the position of relative 2 locking locating tooths of symmetry (10), locking locating tooth (10) is stuck in the positioning hole (12), treat bolt (13) with workpiece fastening after, the locking wing (3) is dug 90 ° bolt head is embraced.Therefore bolt (13) can not become flexible.
Claims (3)
1, a kind of locking washer is characterized in that evenly being provided with 2～10 locking wings in faced washer cylindrical side along the circle direction, and 1～2 locking locating tooth is established in the circle side in the faced washer.
2, locking washer according to claim 1 is characterized in that locking locating tooth and faced washer annulus are in same plane.
3, locking washer according to claim 1 is characterized in that locking locating tooth is vertical with the faced washer annulus.
