Abstract
The utility model discloses a kind of high-performance light wavy spring, including the wave belt with crest and trough, after the wave belt coiling forms spring, the crest and trough of adjacent coils thereof contact with each other；The length of institute's crest and trough contact surface accounts for 25% the 30% of the waveform bandgap wavelength；The upper surface of the crest and the lower surface of trough are respectively equipped with convex portion or recess, and after the crest and trough contact with each other, convex portion and recess cooperate.Because convex portion and recess are mutually spacing in wave belt length direction, twisting resistance can not continue to transmit, so that uniform force on wave belt, spring stress is stable.
Description
Technical field
It the utility model is related to spring, more particularly to a kind of high-performance light wavy spring.
Background technology
Wavy spring is as a kind of novel spring, by multiple sheet metals with crest and trough along helix around cyclization
And formed, it is widely used in the occasions such as automobile, motor, textile machine, hydraulic test.It is advantageous that：Small volume, and provide
Force value is big, suitable for the occasion higher to requirements of installation space.
But after long-term use, the torsional stress inside wavy spring is passed to the position that crest contacts with trough, can
Torsional deflection is brought it about, spring heights reduce, and the force value provided under unit deformation reduces.What is more, and the torsional stress continues
It is transferred to without behind constraint position, easily causes the Joint failure of the position crest and trough, spring can not integrally uses.
Utility model content
The purpose of this utility model is to provide a kind of high-performance light wavy spring, and it is applied to optimization wavy spring
The distribution of internal torsion power under working condition, so as to reach the permanent stable effect used.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of high-performance light wavy spring, including the wave belt with crest and trough, the wave belt coiling are formed
After spring, the crest and trough of adjacent coils thereof contact with each other；The length of institute's crest and trough contact surface accounts for the waveform bandgap wavelength
25%-30%；The upper surface of the crest and the lower surface of trough are respectively equipped with convex portion or recess, and the crest and trough are mutual
After contact, convex portion and recess cooperate.
In one embodiment：The convex portion is salient point, and recess is shrinkage pool.
In one embodiment：The convex portion is raised line, and recess is groove.
In one embodiment：The raised line and groove extend respectively along the width of wave belt.
In one embodiment：The upper surface of the crest and the lower surface of trough have continuous raised line and groove respectively, should
Raised line and groove extend along the width of wave belt；After crest contacts with each other with trough, length of its contact surface in wave belt
Spend direction and form waveform.
In one embodiment：The convex portion and recess pass through punch forming.
Brief description of the drawings
Fig. 1 is the overall front view of wavy spring；
When Fig. 2 is convex portion or recess is salient point and shrinkage pool, both be engaged after schematic perspective view；
When Fig. 3 is convex portion or recess is salient point and shrinkage pool, both be engaged after enlarged partial sectional view；
When Fig. 4 is convex portion or recess is multiple raised lines and groove, the schematic perspective view of lower waveform band；
When Fig. 5 is convex portion or recess is multiple raised lines and groove, both be engaged after enlarged partial sectional view.
Embodiment
Fig. 1-5, a kind of high-performance light wavy spring, including the wave belt with crest and trough are refer to, at this
After wave belt coiling forms spring, the crest and trough of adjacent coils thereof contact with each other.
The wave belt is respectively equipped with convex portion or recess in its crest and trough, after the crest and trough contact with each other,
The convex portion and recess cooperate.The length of institute's crest and trough contact surface accounts for the 25%-30% of the waveform bandgap wavelength, the length
Degree refers to the size of the contact surface along its length so that comparatively crest and trough have more flat surface, contact with each other
Area is larger.Convex portion and recess can be by being stamped to form type to wave belt.
The convex portion is salient point or raised line, and recess is corresponding shrinkage pool or groove.When jog is raised line and groove, its
Extend along the width of wave belt.
In one embodiment, the crest and trough have multiple raised line and groove respectively, and the raised line and groove are along ripple
The width extension of shape band；After crest contacts with each other with trough, its contact surface forms waveform in the length direction of wave belt.
Designed more than, crest and trough contact site are when by twisting resistance, because convex portion and recess are in wave belt
Length direction is mutually spacing, and twisting resistance can not continue to transmit, and the power circumferential along spring is turned by the inclined-plane of concave-convex fit structure
The power along spring axial direction is turned to, so that contact site is not likely to produce the minor shifts in circumference, uniform force on wave belt；
And because contact area increases, spring stress is more stable, the stress distribution in wave belt is also more uniform, so that wavy spring
It is able to light-weight design.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits its scope of the claims, it is every to utilize this
The equivalent structure transformation that utility model specification and accompanying drawing content are made, directly or indirectly it is used in other related technology necks
Domain, similarly it is included in scope of patent protection of the present utility model.
