The designer should have clear knowledge of
the containing space of the compression spring
so as to effectively grasp the basic specifications
of the compression spring, including outer diameter,
inner diameter and solid height etc. |
|
| |
The designer should have clear knowledge of
the spring position and born force of the compression
spring. Material, wire diameter and coil number
can be decided only after determining the position
and the force required. |
|
| |
Used in different environments, the service
life of the spring will be influenced by various
environmental factors. The designer should take
into consideration the temperature and humidity
changes. The temperature has great influence to
the service life of the spring. High humidity
is easy to oxidize the unprocessed spring surface.
Surface treatment and material selection of the
spring are decided by environmental factors. |

|
End-to-end Distance
& Space |
|
|
The two ends of the extension spring will affect
the hang hook style and the solid height of the
extension spring. The space can determine the
size and outer diameter of the adhesion part. |
|
| |
The pre-stretch loading decides the
material and wire diameter of the spring. The
size of adhesion part can adjust the pre-stretch
length. |
|
|
|
Outer diameter of core
axis |
|
|
The inner diameter of the torsion spring is basedon
the size of core axis. The spring changes after
the torsion should also be taken into account.
Considerable allowances should be pre-set. |
|
|
|
Inner Diameter of Container |
|
|
The built-in space of a torsion spring determines
the outer diameter, solid height and coil number
of the spring body. |
|
| |
There should be a pivot supporting
torsion spring’s motion. This pivot decides the
length and style of the torsion bar. |
|
| |
The angle between the torsion bar and the pivot
in motionless state determines the bar length,
style and the angle with the pivot bar. |
