Abstract
The utility model belongs to the technical field of springs, in particular to an improved stress spring. The improved stress spring solves the technical problem that the prior art is not reasonable enough. The improved stress spring comprises a spring body which is formed by a spring wire in a winding mode. The improved stress spring is characterized in that the cross section of the spring wire is divided into an inner side part and an outer side part which are equal in width, and the area of the inner side part is larger than or less than the area of the outer side part. Compared with the prior art, the improved stress spring has the advantages that the design is reasonable, the structure is simple, the stress concentrating portions of the spring are reduced, the fatigue life of the spring is prolonged, the service life of the spring is prolonged, maintenance cost of support equipment is effectively lowered, and the economic benefit requirements of enterprises are met.
Description
Technical field
The utility model belongs to the spring technical field, especially relates to a kind of stress and improves spring.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work.Generally with spring steel, make.In order to motion, the mitigation of controlling parts, impact or shake, store up the size of energy, measuring force etc., be widely used in machine, instrument.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring etc.Be subjected to the impact of product with compact structure design concept, it is very little that many times spring fitting is adjusted space, therefore requires spring to have higher rigidity, causes the design stress of spring higher.Because stress is concentrated, have more more sharp-pointed corner now, therefore adopt the hydraulic spring grease cup of rectangular cross-section wire rod manufacture and engineering spring due to the impact that concentrated by corner's stress, cause fatigue life low, easily cause spring breakage to lose efficacy, and then affected the production and application of corollary equipment, reduce manufacturing efficiency, and improved the maintenance maintenance cost of equipment.
For example, Chinese patent literature discloses a kind of spring [application number: 201020653538.X], for connecting button, it is characterized in that, an end at described spring is provided be used to being welded on two pins on circuit board at least, one end of described spring is provided with the ring circle, and described pin evenly is arranged on described ring circle.
Such scheme still exists: intensity is low, and poor stability easily produces distortion, and the stress of spring is comparatively concentrated, causes spring fatigue life to reduce, thereby has reduced working life, has increased the maintenance cost of enterprise, and time of wasting of service equipment.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, and the stress of long service life improves spring.
For achieving the above object, the utility model has adopted following technical proposal: should power improve spring, comprise the spring body formed by the spring wire coiling, it is characterized in that, the cross section of described spring wire is divided into inboard part and the external lateral portion that width equates, and the area of inboard part is greater than or less than the area of external lateral portion.
Further, according to different purposes springs, the spring that the spring inside portion component of stress is large adopts the area of inboard part to be greater than the area of external lateral portion; The spring that spring external lateral portion stress is large adopts the area of inboard part to be less than the area of external lateral portion, thereby reaches the dispersive stress purpose, has reduced the stress concentration portion of spring, has improved spring fatigue life.
At above-mentioned stress, improve in spring, described cross section is any one shape in water-drop-shaped, avette, isosceles trapezoid, fan shape.
As preferably, the cross section stresses dispersion effect of water-drop-shaped is good, and can reduce material consumption, reduces cost of material.
At above-mentioned stress, improve in spring, described cross section by large arcuate segment, little arcuate segment and be connected to large arcuate segment and little arcuate segment between two line segments surround and form, and be connected smoothly between each line segment.
At above-mentioned stress, improve in spring, described spring wire is made with any one in elastic alloy with nickel alloy, spring with Cuprum alloy, spring by spring steel, spring stainless steel, spring.Further, can, according to different user demands, select the most applicable material to make cross section and be the water-drop-shaped spring.
At above-mentioned stress, improve in spring, be compounded with anticorrosive coat on described spring wire.
Further, owing to being compounded with anticorrosive coat, thereby can extend the working life of spring, make spring more durable.
Compared with prior art, the advantage of should power improving spring is: reasonable in design, simple in structure, reduce the stress concentration portion of spring, improved spring fatigue life, extended working life, effectively reduce the maintenance cost of corollary equipment, meet the Business Economic Benefit requirement.Particularly water-drop-shaped cross section stresses dispersion effect is good, and can reduce material consumption, reduces cost of material.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
Fig. 2 is the structure for amplifying schematic diagram of cross section in the utility model
In figure, spring wire 1, spring body 2, cross section 11, inboard part 11a, external lateral portion 11b, large arcuate segment 111, little arcuate segment 112, line segment 113.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, should power improve spring, comprise the spring body 2 formed by spring wire 1 coiling, the cross section 11 of spring wire 1 is divided into inboard part 11a and the external lateral portion 11b that width equates, and the area of inboard part 11a is greater than or less than the area of external lateral portion 11b.According to different purposes springs, the spring that the spring inside portion component of stress is large adopts the area of inboard part to be greater than the area of external lateral portion; The spring that spring external lateral portion stress is large adopts the area of inboard part to be less than the area of external lateral portion, thereby reaches the dispersive stress purpose, has reduced the stress concentration portion of spring, has improved spring fatigue life.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more been used the terms such as spring wire 1, spring body 2, cross section 11, inboard part 11a, external lateral portion 11b, large arcuate segment 111, little arcuate segment 112, line segment 113, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
