Abstract
The utility model discloses a kind of motor springs of high fatigue, and including the spring body made of spring wire, which orients screw winding successively, forms cylindrical shape, the helix angle of the spring wire is between 4 ° 7 °；A diameter of 5 55mm of the spring wire, the substance of spring corresponding with spring wire is 0.2 1.5kg, and elastic protecting sleeve is coated in the outer surface of the spring wire, and the thickness of the elastic protecting sleeve is 1/3rd of the wire diameter；The pitch of the spring wire is equal.On the premise of spring force and spring outer diameter are certain, the phenomenon that excessive or too small, will not occur for wire diameter, avoid that spring string diameter is too small to cause elastic force deficiency and spring string diameter is excessive that helix angle is caused to increase.Elastic protecting sleeve and metal frame friction, avoid the generation of noise, and elastic protecting sleeve can play a protective role to spring steel wire, be not only simple in structure, and cost is relatively low, and use noiseless generation, and service life is long.
Description
Technical field
The utility model is related to spring technical field more particularly to a kind of motor springs of high fatigue.
Background technology
At present, since the design of spring is related to deeper machine-building design theory, part of the manufacturer can not really by
Spring design theory is really all connected with specific spring production process, produces the high-quality spring of high quality, especially
It is the inherence between spring ring outer diameter, wire diameter (abbreviation spring string diameter), helix angle, pitch, rigidity, fatigue strength etc.
Contact and the contact between actual production technique and each performance indicator and production technology realize the ability of each performance indicator, into
One step says on the premise of spring material performance is substantially met how to pass through spring ring outer diameter, spring string diameter, helix angle and bullet
Spring coil number etc. requires index to produce the good high-quality spring of anti-fatigue performance, does not obtain directly solving well.
Utility model content
The utility model provides a kind of motor spring of high fatigue to overcome deficiency of the prior art.
The utility model is to be achieved through the following technical solutions：
A kind of motor spring of high fatigue, including the spring body made of spring wire, which orients spiral successively
Winding forms cylindrical shape, and the helix angle of the spring wire is between 4 ° -7 °；A diameter of 5-55mm of the spring wire, with
The substance of the corresponding spring of spring wire is 0.2-1.5kg, and elastic protecting sleeve, the bullet are coated in the outer surface of the spring wire
Property protective case thickness be the wire diameter 1/3rd；The pitch of the spring wire is equal.
Further, the spring wire is made of titanium alloy material.
Further, the elastic protecting sleeve is adopted made of plastic.
Further, and in the outer surface of the elastic protecting sleeve it is machined with fine and closely woven miniature oilhole.
Compared with prior art, the beneficial effects of the utility model are：Before spring force and spring outer diameter are certain
Put, the phenomenon that excessive or too small, will not occur for wire diameter, avoid spring string diameter it is too small cause elastic force deficiency and spring
String diameter is excessive to cause helix angle to increase.Elastic protecting sleeve and metal frame friction avoid the generation of noise, and elasticity is protected
Sheath can play a protective role to spring steel wire, be not only simple in structure, and cost is relatively low, and use noiseless generation, use
Long lifespan.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Referring to Fig. 1, a kind of motor spring of high fatigue, including the spring body made of spring wire 1, the bullet
Spring silk orients screw winding successively, forms cylindrical shape, the helix angle of the spring wire 1 is between 4 ° -7 °；In spring force
With spring outer diameter it is certain on the premise of, the phenomenon that excessive or too small, will not occur for wire diameter, and it is too small to avoid spring string diameter
Cause elastic force deficiency and spring string diameter is excessive that helix angle is caused to increase.
Referring to Fig. 1, a diameter of 5-55mm of the spring wire 1, is 0.2- with the substance of 1 corresponding spring of spring wire
1.5kg。
Referring to Fig. 1, being coated with elastic protecting sleeve 2 in the outer surface of the spring wire 1, the elastic protecting sleeve 2 uses
Plastics are made, and the thickness of the elastic protecting sleeve 2 is 1/3rd of 1 diameter of spring wire, and in the elastic protecting sleeve 2
Outer surface be machined with fine and closely woven miniature oilhole, the pitch of the spring wire 1 is equal.Elastic protecting sleeve 2 and metal frame friction,
The generation of noise is avoided, and elastic protecting sleeve 2 can play a protective role to spring steel wire 1, be not only simple in structure, cost
It is relatively low, and noiseless generation is used, service life is long.
Referring to Fig. 1, the spring wire 1 is made of titanium alloy material, since titanium alloy is strong, relatively low with higher ratio
Elasticity modulus, therefore the spring made of titanium alloy has the characteristics that high resiliency, high intensity, high-ductility and steel spring phase
Than having preferable fatigue resistance and sensitivity, in addition the titanium alloy spring is high etc. with light-weight, small and resonant frequency
Advantage.
The preferred embodiment of the utility model is above are only, is not intended to limit the utility model, it is all in this practicality
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in the guarantor of the utility model
Within the scope of shield.
