2. the resistance body 301 of solid of rotation 30 internal diameters contacts slightly with an end of public housing 10, the reciprocal axial displacement maximum that solid of rotation 30 is stretched to helical spring 40;
3. the resistance body 301 at solid of rotation 30 internal diameters pushes against part to the plain line 401 of spring, and the resistance body 301 of solid of rotation 30 internal diameters separates with the plain line 401 of spring, and micro-gap is arranged.
Behind the initial setting, this moment tension type adjustable helical spring elasticity coefficient minimum, the number of active coils maximum of its helical spring 40.
Increase pretensioning: rotate pre-power knob 801, make public housing 10 and solid of rotation 30 do axial displacement to the direction that helical spring 40 stretches, the resistance body 301 of solid of rotation 30 internal diameters is pushed against to the plain line 401 of spring, so the pretensioning of the helical spring 40 of number of active coils part increase.
Reduce the set-up procedure of the number of active coils (increase elasticity coefficient) of helical spring 40:
Step 1: reduce pretensioning, make spring pitch revert to the pitch of solid of rotation: to rotate pre-power knob 801, make public housing 10 and solid of rotation 30 do axial displacement to the opposite direction that helical spring 40 stretches, then the resistance body 301 of solid of rotation 30 internal diameters separates with the plain line 401 of spring, and small gap is arranged, and therefore the pretensioning of whole helical spring 40 reduces;
Step 2: the number of active coils that reduces helical spring 40: rotate solid of rotation 30, make solid of rotation 30 do axial displacement and rotation to the opposite direction that helical spring 40 stretches, up to the revolution that reaches setting, if the resistance body 301 of solid of rotation 30 internal diameters contacts with the plain line 401 of spring, and when solid of rotation 30 can not effectively be rotated, return step 1;
Step 3: the step of increase pretensioning as mentioned above.
Increase the set-up procedure of the number of active coils (minimizing elasticity coefficient) of helical spring 40:
Step 1: reduce pretensioning, make spring pitch revert to solid of rotation pitch step as mentioned above;
Step 2: the number of active coils that increases helical spring 40: rotate solid of rotation 30, make solid of rotation 30 do axial displacement and rotation to the direction that helical spring 40 stretches, up to the revolution that reaches setting, if the resistance body 301 of solid of rotation 30 internal diameters contacts with the plain line 401 of spring, and when solid of rotation 30 can not effectively be rotated, return step 1;
The step of step 3, increase pretensioning as mentioned above.
Public housing internal diameter is greater than the adjusting method of the regulating device of parent shell external diameter, tension type adjustable helical spring and internal diameter formula solid of rotation, as mentioned above.
