The termination radius of above involute sheave can be determined according to following relational expression: stop radius=start radius * (plane scroll spring group termination moment of torsion/plane scroll spring group starting torque)
This formula derivation is as follows, establishes:
Plane scroll spring group starting torque: N1
Plane scroll spring group termination moment of torsion: N2
Steel rope initial force: F1
Steel rope stops power: F2
Sheave start radius: r1
Sheave stops radius: r2
According to spring performance: N1=F1*r1, N2=F2*r2
That is: F1=N1/r1 F2=N2/r2
If will guarantee that output procedure load is constant, then: F1=F2
That is: N1/r1=N2/r2
Can get thus: r2=r1*N2/N1
Two of the technical scheme of constant tension compensating mechanism of the present invention is: comprise the spring that is installed on pedestal, it is characterized in that: described spring is at least one permanent moment of torsion plane scroll spring, one end and pedestal relative fixed, the other end and main shaft relative fixed, described main shaft support is on pedestal, be fixed with on the main shaft and decide chute wheel or spiral sheave, be wound with the steel rope that connects outside catenary or contact wire on the described sheave.
Like this, when catenary and contact wire cause length variations because of variation of ambient temperature, permanent moment of torsion plane scroll spring all can be by the regulating and compensating role of spring tension with the matched combined of the matched combined of deciding chute wheel or spiral sheave or change moment of torsion plane scroll spring and involute sheave, make to keep substantially invariable tension force on catenary and the contact wire, thereby satisfy the needs of electrified railway engineering.Simultaneously, the matched combined of plane scroll spring and sheave has compact conformation, volume is small and exquisite, weight is light, advantage easy to adjust is installed, so the present invention obtains practical applying easily.
