TRY Spring Detailed Performance
DAI Spring Choosing Method
Take the exactly 4 data for Working Load, Spring Outside Diameter, Using Time, and the Deflection before choose our DAI spring .
1. Working Load 3.334N
2. Spring Outside Diameter 12.0mm
3. Using Time 4,000,000-time Use
4. Deflection 60mm
Look at the below Load Curve by 1,000,000-time Use, focus on the vertical axis of Load ( kgf ) by 100kgf, find the crossing point from the horizontal axis of Outside Diameter by 25mm, we can know the load grade information.
Based on the Load Curve, by 1,000,000-time Use, when the deflection is 25mm, the below RED 25-100 spring was selected:
|wire diameter(mm)||Outside Diameter(mm)||inside Diameter(mm)||Free Length(mm)||constant(N/mm)|
DAI Spring Using Precautions
When you use DAI Spring, please observe the following instructions.
Use Over Maximum Deflection (300,000-time Condition) (Use Near Closing Position)
As illustrated in the drawing on the right hand, use over 300,000-time condition will be become the use around solid length. Around the solid length, since the number of active coils will become gradually coherent, the spring constant will become higher, and as illustrated, the load characteristic rises and becomes high stress, which would cause damage to products. Please refrain from using over 300,000-time condition.
Use without Initial Deflection
Use with any space will give impact and cause damage to spring. Be sure to use with the initial deflection of 1mm or more.
Use by Nipping Scrap or Foreign Articles
As illustrated in the drawing on the right side, when any foreign articles is caught in spring, such part will not work as number of active coils, and the number of active coils will substantially become reduced, which would cause higher spring constant and damage to spring. Also, the solid length will become longer.
Use Where the Parallelism of Mounted Surface Is Not Good
Bad parallelism of mounted surface would cause twisting or damage to spring. Be sure to check the parallelism.
Do not use without spring guide
Use without spring guide would cause twisting or damage to spring. Be sure to use spring guide such as shaft or outside diameter guide.
When the using environmental temperature becomes higher, substantial function loss will occur. Be careful about using environmental temperature.
