Description

Wavy spring

Technical field

The utility model relates to a kind of elastic component, and more particularly, it relates to a kind of wavy spring.

Background technique

Wavy spring is called for short ripple spring, it is the thin slice annular resilient metallic member be made up of some Wave crest and wave troughs, high-quality spring steel 65Mn (60Si2MnA/50CrVA/0Cr17Ni7Al/SUS304) selected by this spring, through ad hoc approach heat treatment also as the case may be, hardness general control is between HRC44-55, surface blackening, there is favorable elasticity, wavy spring is widely used in motor, textile manufacturing machine, hydraulic equipment, automobile and other industries, in main installation and specification (nominal size) suitable bearing chamber or hole, installing space is very little, there is reduction noise, reduce the specific function of vibration.

In prior art, be disclose a kind of wavy spring in the Chinese utility model patent of CN201320050599.0 at application number, described wavy spring be by a undulatory bar shaped plate body by width direction centrally axle screw winding form, the free height of this wavy spring is 3 ~ 3.5mm, internal diameter is 14.6 ~ 39mm, external diameter is 17.15 ~ 45.2mm, and the wavy spring endurance of this model utility, can make door lock long service life.

Wavy spring in this model utility improves the fatigue performance of wavy spring by the mode limiting wavy spring size, thus extend the life-span of wavy spring, but wavy spring is still thin circle structure due to its peak valley, the load that can bear and amount of deformation are still limited.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of fatigue performance is good, the wavy spring of long service life.

For achieving the above object, the utility model provides following technological scheme: a kind of wavy spring, wherein: comprise at least four wavy spring circles, described wavy spring circle includes multiple crest and multiple trough, described crest and the interlaced setting of trough, the described stacking setting of wavy spring circle concentric, and the crest of described wavy spring circle is fixedly connected to form joint with the trough of the wavy spring circle be adjacent, described each joint is provided with the permanent magnet of bar shaped, the south poles line direction of described permanent magnet and the parallel to an axis of described wavy spring, and the pole orientation of described any two adjacent permanent magnets is contrary.

By adopting technique scheme, described wavy spring can bear axial pressure and produce resiliently deformable, when described wavy spring compression, joint on described adjacent wavy spring circle is close to each other, and described permanent magnet is also close to each other, because the pole orientation of described any two axially adjacent permanent magnets is contrary, namely the homopolarity of described adjacent permanent magnet is close to each other when described wavy spring is compressed, according to homopolar-repulsion principle, mutually the repulsive force contrary with described wavy spring compression direction is produced between described permanent magnet, thus share pressure that described spring bears and help described wavy spring to cancel the original length of reply at pressure, thus improve the fatigue performance of described wavy spring, extend the working life of described wavy spring.

The utility model is set to further: the two ends of described permanent magnet are provided with the buffer layer that elastic material is made.

By adopting technique scheme; described buffer layer provides buffer function when the compression of described wavy spring for described permanent magnet; play the effect protecting described permanent magnet, be hit in the process preventing described permanent magnet from compressing at described wavy spring excessive and cracked damage.

The utility model is set to further: the crest on described wavy spring circle and trough quantity arrange and is set to four all respectively.

By adopting technique scheme, joint on described wavy spring is eight groups simultaneously and is evenly distributed on the circumference of wavy spring, thus make described wavy spring in compression process, the repulsive force that described permanent magnet provides is more even, the off-axis that described wavy spring is produced in movement process to motion less, thus avoid the unusual deformation of described wavy spring, extend the working life of described wavy spring.

Compared with prior art, wavy spring in the utility model adopts on adjacent joint, is provided with the contrary permanent magnet of pole orientation, the repulsive force relying on described permanent magnet to produce time close to each other is to share the resistance of deformation of described spring, structure, effectively improve the fatigue performance of described wavy spring, extend the working life of described wavy spring.

Embodiment

Referring to figs. 1 through Fig. 3, the utility model spring embodiment is described further.

A kind of wavy spring, comprise six wavy spring circles 1, described wavy spring circle 1 includes four crests 2 and four troughs 3, described crest 2 and the interlaced setting of trough 3, the described stacking setting of wavy spring circle 1 concentric, and the crest 2 of described wavy spring circle 1 is fixedly connected to form joint 8 with the trough 3 of the wavy spring circle 1 be adjacent, as shown in the accompanying drawings 1, the trough 3 being positioned at the wavy spring circle 1 of top is fixedly connected with the crest 2 of the wavy spring circle 1 be positioned at below it, preferably, described joint 8 is set to line part 6, described permanent magnet 4 can be better installed, described joint 8 offers mounting hole 7, described each joint 8 is provided with the permanent magnet 4 of bar shaped, described permanent magnet 4 is fixedly located in described mounting hole 7, make the south poles line direction of described permanent magnet 4 and the parallel to an axis of described wavy spring in this way, and the pole orientation of described any two adjacent permanent magnets 4 is contrary.

The concrete principle of the present embodiment is as follows: described wavy spring can bear axial pressure and produce resiliently deformable, when described wavy spring compression, joint 8 on described adjacent wavy spring circle 1 is close to each other, and described permanent magnet 4 is also close to each other, because the pole orientation of described any two axially adjacent permanent magnets 4 is contrary, namely the homopolarity of described adjacent permanent magnet 4 is close to each other when described wavy spring is compressed, according to homopolar-repulsion principle, mutually the repulsive force contrary with described wavy spring compression direction is produced between described permanent magnet, thus share pressure that described spring bears and help described wavy spring to cancel the original length of reply at pressure, thus improve the fatigue performance of described wavy spring, joint 8 on described wavy spring is eight groups simultaneously and is evenly distributed on the circumference of wavy spring, thus make described wavy spring in compression process, the repulsive force that described permanent magnet 4 provides is more even, the off-axis that described wavy spring is produced in movement process to motion less, thus avoid the unusual deformation of described wavy spring, extend the working life of described wavy spring.。

The two ends of described permanent magnet 4 are provided with the buffer layer 5 that elastic material is made; described buffer layer 5 is sticked at the two ends of described permanent magnet 4; described buffer layer 5 can adopt rubber to make; described buffer layer 5 provides buffer function when the compression of described wavy spring for described permanent magnet 4; play the effect protecting described permanent magnet 4, be hit in the process preventing described permanent magnet 4 from compressing at described wavy spring excessive and cracked damage.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
