TORQUE SPRING
ENGLISH
GOVERNOR SYSTEM
24.3 Single spring type
When installing the single-spring type torque spring set,
use the following procedure:
1. Turn the adjust screw 5 lightly (with a screwdriver)
until a resistance is felt. Lightly lock the screw at
that position with locknut 4.
2. Set the scale to the zero-point. Turn the spring
case 2 until the value of load “A” shown in tablle
below can be attained. Lock the spring case at that
position with special nut 3. Special nut tightening
torque: 14.7 to 24.5 N.m (1.5 to 2.5 kg.m) [10.8 to
18.1 lbf.ft]
3. Temporarily loosen adjust screw 5 until the value of
load “A” is reduced by about 200 grams [7.06 oz],
and then retighten the screw until the value of “B”
is attained. Lock the screw at that position with
locknut 4. Adjust screw tightening torque: 7.8 to
11.8 N.m (0.8 to 1.2 kgf.m) [5.8 to 8.7 lbf.ft].
4. To inspect if the torque spring set is properly
adjusted spring load, arrange a spring set as
shown in the figure at right. Gradually push the
scale against the torque spring set until the stopper
1 is moved (or the pointer of dial gage deflects).
Check that the load applied to the torque spring at
that moment coincides with the value of load “C”
shown in the table.
