Description
Technical field
The present invention relates to mechanical spare and accessory parts technical field, and in particular to a kind of spring washer.
Background technology
Spring washer and threaded fastener are used as the mechanical basic part being fastenedly connected, and are widely used in the company often dismantled
Socket part position.Annulus of the structure of spring washer generally with an angle（See Fig. 1）, it by spring washer high resiliency and
The acute angle cutting edge of angle edge formation prevents the loosening of fastener, so as to avoid the loosening of connected piece or the caused machine that comes off
Tool component function scatters and disappears, or even accident occurs.Although people have carried out many to the loose or dislocation problem that screw threads for fastening is connected
Analysis and research, but because connector caused by spring washer piston ring loosens failure phenomenon and still happened occasionally.
Piston ring refers to spring washer during the assembling or after assembling, opening value occurs and increases overproof phenomenon, also
It is that the diameter of spring washer becomes big, outwards expansion（See Fig. 2）.Piston ring is totally unfavorable to the using effect of spring washer, because it
It can reduce or lose the locking effect of spring washer.
Spring washer can be divided into three phases when being fastenedly connected by the course of work compressed.First stage, spring
The elastic compression deformation stage of packing ring, spring washer is compressed in the presence of nut rotation screw-down torque, as compression becomes
Shape gradually increases, and the elastic force of spring washer also gradually increases, and generally spring washer follows spiral shell in this process
Female and rotation phenomenon.Second stage, spring washer is fully compressed as a spring, and elastic deformation amount reaches maximum, this
When spring washer, connected piece and nut between be in close contact.Phase III, nut is tightened until the torque demand of design, this
During individual the contact site of spring washer, connected piece and nut be possible to occur under compressive forces spring washer with
Relative motion between nut, it is also possible to be spring washer and nut without relative motion, but have phase with connected workpiece
To motion.
Observation through overtesting and production scene, the piston ring phenomenon of spring washer appears in the phase III of installation process.
The phenomenon now produced is that screw-down torque does not reach design requirement, and the portion of packing ring circumference substantially exceeds nut gabarit, tiltedly
Mouth opens.
Actually because the sectional dimension of spring washer has an error, there are stretch marks when drawing packing ring wire rod, above and below packing ring
Rough surface and coiling processing when due to technique the need for have clamping and form impression, also spring winding packing ring when due to mould
The reason for be also possible to make packing ring in radial skew（Packing ring is tub-shaped）.These situations can all make packing ring on two contact surfaces not
With the frictional force of position, size is unequal in a circumferential direction.Meanwhile, spring washer is not a complete annulus, but is deposited
In an angle.Spring washer be driven plain after because the thickness at angle is big, so the compression stress ratio born near angle
Larger, frictional force in rundown process is also than larger, and remaining position contact portion Area comparison is small or even contactless.
Twist, packing ring is compacted rear two surfaces up and down and is respectively formed plane spring washer, still when starting to tighten nut
Analyzed more than, preferable plane contact can not possibly be presented with nut and connected piece in packing ring.So packing ring is made by moment of torsion
Used time, packing ring upper and lower surface is unbalanced due to frictional force size, make diverse location gasket materials make a concerted effort be not zero, it is this
The unbalanced angle position for making a concerted effort to ultimately result in spring washer is not that to be opened be exactly near by pressure.That is, piston ring fails
It is due to that frictional force under individual cases at angle can not be balanced by gasket materials itself internal force, only by packing ring
It is plastically deformed to eliminate.
As can be seen here, this traditional spring washer is difficult to the generation for being inherently eliminated piston ring phenomenon.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of be not in piston ring phenomenon spring washer.
In order to solve the above technical problems, the technical scheme is that：A kind of spring washer, including by elastic metallic material
The washer body being made, the washer body is the circular ring structure of closing, including outer ring surface, inner ring surface, upper surface, lower surface；
The groove for alternatively setting at least one to run through upper and lower surface on the outer ring surface or inner ring surface, the both sides of each groove are equal
Form two corners, the angle direction clockwise direction of one of corners, the angle direction side counterclockwise of another corners
To；At least one corners is folded upward at being raised in upper surface, and at least one on whole outer ring surface or whole inner ring surface
Corners bending downwards is raised in lower surface, and the angle of all corners for being raised in upper surface owns towards clockwise
The angle of corners of lower surface is raised in towards counterclockwise.
The beneficial effects of the invention are as follows：Due at least one point on the whole outer ring surface or whole inner ring surface of washer body
Corner is folded upward at being raised in upper surface, and bending is raised in lower surface at least one corners downwards, all to be raised in
The angle of the corners on surface is towards clockwise, and the angle of all corners for being raised in lower surface is towards side counterclockwise
To.So in use, when tightening nut clockwise, all corners can be driven plain, and because washer body is
The circular ring structure of closing, thus fundamentally avoids the generation of piston ring phenomenon；And if rotation counterclockwise occurs in nut loosening
When turning, corners then relies on natural resiliency resilience, the wedge angle of raised corners be pierced into nut and connected piece surface so as to
Play a part of to prevent nut loosening.Furthermore, the spring washer of this structure uses steel plate or steel strip stamping to be formable, production effect
The more original coiling shaping of rate increases.
In one embodiment, three alternatively are uniformly arranged on the outer ring surface or inner ring surface and run through upper and lower surface
Groove.
Preferably, three grooves are sector structure.
It is highly preferred that the fan-shaped angle is 60 degree.
In one embodiment, six alternatively are uniformly arranged on the outer ring surface or inner ring surface and run through upper and lower surface
Groove.
In one embodiment, there are three corners to be folded upward at being raised in upper surface, there are three corners to bend downwards
It is raised in lower surface.
Preferably, the groove is angularly disposed.More sharp corners can be so formed on groove both sides.
Preferably, the washer body is made up of spring steel.
