Torsion spring belongs to the compression spring.
Torsion spring mechanical energy can be stored and release Angle or axial rotation arm torsion body based on static fixed a machine equipment.
Spring manufacturer introduce torsional spring beam end is fixed to the other artifacts, when other artifacts around the bomb huang administration rotates, the yellow they will drag the initial position, turn lead to torque or driving force.
Then its main parameters have?
Everybody together to hold below: nominal diameter size tolerance + / - 2%.
De(
Diameter)
: equals nominal diameter and two times of cable diameter.
Torsion spring in the work process, will be smaller in diameter, size tolerance,
±2%±0.

L0(
Nature length)
: note: in the process of work nature length decreases, the dimensional tolerance + / - 2%.
Ls(
Support column length)
: this spring coil to the length of the body axis to playing the yellow columns, dimensional tolerance + / - 2%.
An(
A large distortion Angle)
:
torsion spring big twist Angle, size tolerance + / - 15 degrees.
d(
Spring wire diameter)
Description: the main parameters for the diameter of the spring line.
Dd(
Journal large diameter)
Description: the main parameters of is the large diameter of industrialization production application shot yellow shaft, dimensional tolerance + / - 2%.
Di(
Nominal diameter)
: nominal diameter is equal to the diameter of the spring minus two times of cable diameter.
Torsion spring in the work process, the nominal diameter can be reduced to journal diameter, A1 & amp;
f1
M1:(
Twist Angle, load and torque)
: the following expression should calculate distortion Angle A1 = M1 / R.
Master load to calculate expressions M = F * Ls torque.
Fn(
A big load)
: allows the effect on the torsional spring shores is full, the dimensional tolerance + / - 15%.
Mn(
Torque)
: big allowed torque (
Copernicus * mm)
, size tolerance + / - 15%.
R(
Spring stiffness)
: the main parameters play yellow when work on friction.
Copernicus * mm/degree, size tolerance + / - 15%.
Columns location: the column propping up of torsion spring has four location: 0 ° and 90 °, 180 ° and 270 ° (
Please see in the picture)

Spiral direction: right whose hands direction spin, the spring left-handed playing Huang Shun spin clockwise direction.
Everyone can all play Huang Er type spin to production and processing.
Play yellow part number: every play yellow often appear only number: type.
