Abstract
The utility model relates to the field of springs, which discloses a titanium spring, wherein the spring is coiled to a helical form by titanium alloy rod, compared with a steel spring, the titanium spring has light weight, excellent fatigue resistance, corrosion resistance and sensitivity. Using the technical scheme of the example of the utility model, the spring which is coiled to the helical form by the titanium alloy rod is used, because titanium alloy has higher specific strength and lower elastic modulus, the spring which is made by the titanium alloy has the characteristics of high elasticity, high strength and high plasticity, compared with the steel spring, the titanium spring has light weight, excellent fatigue resistance, corrosion resistance and sensitivity.
Description
Technical field
The utility model relates to the spring field, relates in particular to a kind of titanium spring.
Background technique
Spring is the indispensable application components of industry-by-industry such as aviation, military affairs, boats and ships, automobile, bicycle, motorcycle, oil, chemical industry, mechano-electronic, hardware fitting.
In order to ensure that spring can work reliably, its material has the higher ultimate strength and yield limit except that satisfying, and also must have higher limit of elasticity, fatigue limit, impact toughness, plasticity and good heat treatment process etc.Present spring generally adopts Steel Alloy, makes such as carbon spring steel, low Manganese Spring Steel, silicon-manganese spring steel and chromium vanadium steel etc.But there are shortcomings such as Heavy Weight, corrosion resistance difference in the steel spring.
In the prior art for prevent the steel spring be corroded cause unavailable, people have adopted diameter that adds big spring or the means that increase cover coat to reach this purpose, but all corresponding weight that further increases the weight of spring of these means impacts for the application of spring.
The model utility content
The utility model embodiment provides a kind of titanium spring, compare with the steel spring have weight gentlier, fatigue resistance, corrosion resistance and sensitivity preferably.
The titanium spring that the utility model embodiment provides, described spring is made of the titanium alloy wire coiled.
Optionally, in this titanium spring, described titanium alloy is: high-intensity beta-titanium alloy.
Optionally, in this titanium spring, described titanium alloy is: Ti-3Al-8V-6Cr-4Mo-4Zr.
Optionally, in this titanium spring, described titanium alloy is: Timetal LCB FTB29.
By on see, use the utility model embodiment's technological scheme, employing is by the titanium spring of titanium alloy wire coiled structure, since titanium alloy have higher ratio by force, lower Young's modulus, therefore the spring of making of titanium alloy has the characteristics of high elasticity, high strength, high-plasticity, compared with the steel spring weight gentlier, fatigue resistance, corrosion resistance and sensitivity preferably.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
The structural representation of a kind of titanium spring that Fig. 1 is provided for the utility model embodiment 1;
Fig. 2 is the left view of the titanium spring of structure shown in Figure 1.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
The structural representation of a kind of titanium spring that Fig. 1 provides for present embodiment, Fig. 2 are the left view of the titanium spring of structure shown in Figure 1, show that as Fig. 1,2 this titanium spring is made of the titanium alloy wire coiled.
Since titanium alloy have higher ratio by force, lower Young's modulus, therefore the spring of making of titanium alloy has the characteristics of high elasticity, high strength, high-plasticity, has compared fatigue resistance and sensitivity preferably with the steel spring.
In addition,, compare with steel spring with the titanium spring that titanium alloy is made because titanium alloy has corrosion-resistant, high strength, high elasticity, nonmagnetic, low aftereffect, characteristics such as be quick on the draw, have in light weight, volume is little and the resonant frequency advantages of higher.Concrete compares with steel: the density of titanium alloy and Young's modulus have only half of steel, but intensity is almost the same with steel.Owing to have these characteristics, the titanium spring can be designed littler in actual applications, the number of turns lacks than the steel spring diameter.With regard to spring, high strength is to the most important performance requirement of material, so high-intensity beta-titanium alloy (is the optimal selection of making spring as Ti-3Al-8V-6Cr-4Mo-4Zr and titanium alloy LCB FTB29 alloy).
Convenient in weight, the spring with identical elastic qualities, if a titanium spring than the light 3.06kg of corresponding steel spring, so four supported springs in automobile, but about weight reduction 12kg.Replace steel spring can solve the problem that the steel spring is oversize, diameter is too big that is always perplexing artificers for a long time easily with the titanium spring.
In addition, because titanium alloy has excellent corrosion resistance, so, can cancel coating, thereby further reduce weight.Such as can in racing car, using the titanium spring.For example, Timetal LCB spring is used for racing car, approximately can weight reduction 36kg about, each racing car probably can alleviate 100 grams like this needs about 1500 yuan of membership dues, especially, at aviation field, the effect of the meaning of the titanium spring of application present embodiment is just bigger on air equipment.
As fully visible, adopt the utility model embodiment's titanium spring, can significantly reduce the manufacture cost of its application.
More than technological scheme that the utility model embodiment is provided be described in detail, used specific case herein the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as restriction of the present utility model.
Claims (4)
