Abstract
The invention discloses a contact flat spiral spring device which consists of a contact flat spiral spring, a spiral spring box, an outer ring, a rivet and a mandrel. The inner end of the contact flat spiral spring is fixed to the mandrel, and the outer end of the contact flat spiral spring is fixed to the outer ring. One end of the outer ring is fixed to the spiral spring box to form an outer ring outer circle, the other end of the outer ring form an outer ring inner circular arc, and the outer ring outer circle and the outer ring inner circle clamp the outer end of the contact flat spiral spring. A bent hook is arranged at the inner end of the contact flat spiral spring and is hooked on the mandrel, the outer end of the contact flat spiral spring is fixed between the outer ring outer circle and the outer ring inner circular arc by using a rivet, one end of the outer ring is hooked on the spiral spring box, and the outer ring inner circular arc at the other end of the outer ring clamps the outer end of the contact flat spiral spring through about arc length of a 1/4 circle. The contact flat spiral spring is very small in layered friction, and output torque of the spring is very stable.
Description
Technical field
What the present invention relates to is a kind of contact-type flat spiral spring device, specifically, is the stable contact-type flat spiral spring device of a kind of output torque.
Background technique
Through finding the literature search of prior art, existing contact-type flat spiral spring is when tightening and loosen, and the state of spring is eccentric, has every layer all tightly to touch, spring interfacial friction is operationally very large, causes the output torque of spring to alter a great deal.
Summary of the invention
The object of the present invention is to provide a kind of contact-type flat spiral spring, its interfacial friction is very little, and the output torque of spring is very steady.
The present invention is made up of contact-type flat spiral spring, coil spring box, outer ring, rivet, mandrel.Contact-type flat spiral spring the inner is fixed on mandrel, and contact-type flat spiral spring outer end is fixed on outer ring; Described one end, outer ring is fixed on coil spring box, forms outer ring cylindrical, and the outer ring the other end forms outer ring Inner arc, and outer ring cylindrical and outer ring Inner arc grip the outer end of contact-type flat spiral spring.Contact-type flat spiral spring the inner has crotch to be hooked on mandrel, contact-type flat spiral spring outer end rivet is fixed between outer ring cylindrical and outer ring Inner arc, described one end, outer ring has crotch to be hooked on coil spring box, and the other end outer ring Inner arc has the arc length of 1/4 circle nearly to clamp the outer end of contact-type flat spiral spring.
The present invention uses external force that mandrel is rotated in the counterclockwise direction, at this moment the contact-type flat spiral spring be fixed on mandrel will be wrapped on mandrel, when external force disappears, contact-type flat spiral spring will be with moving mandrel to rotate clockwise, spring is in relaxation state, one end due to outer ring is close on the outer end of contact-type flat spiral spring, stop contact-type flat spiral spring when loosening toward eccentric on one side, it is all essentially concentric that such spring often encloses when loosening, the increase causing spring interfacial friction towards one side bias can not be produced, ensure that moment of torsion exports stable.
Accompanying drawing explanation
Fig. 1 contact-type flat spiral spring sectional arrangement drawing.
1 coil spring box, 2 rivets, 3 outer rings, 31 outer ring cylindricals, 32 outer ring Inner arc, 4 contact-type flat spiral springs, 5 mandrels.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
Described contact-type flat spiral spring is made up of fixed plate coil spring box 1, rivet 2, outer ring 3, contact-type flat spiral spring 4, mandrel 5 etc.Described one end, outer ring is fixed on coil spring box, forms outer ring cylindrical 31, and the outer ring the other end forms outer ring Inner arc 32.
Contact-type flat spiral spring 4 one end (the inner) of the present invention has crotch to be hooked on mandrel 5, and the other end (outer end) is fixed on outer ring 3 with rivet 2.Described one end, outer ring 3 has crotch to be hooked on coil spring box 1, and the other end has the arc length of 1/4 circle to be nearly close on the outer end of contact-type flat spiral spring 4.
Concrete mode of execution is: by external force, mandrel 5 is rotated in the counterclockwise direction, at this moment the contact-type flat spiral spring 4 be fixed on mandrel will be wrapped on mandrel, when external force disappears, contact-type flat spiral spring 4 will be with moving mandrel 5 to rotate clockwise, contact-type flat spiral spring 4 is in relaxation state, one end due to outer ring is close on the outer end of contact-type flat spiral spring 4, stop contact-type flat spiral spring 4 when loosening toward eccentric on one side, it is all essentially concentric that such contact-type flat spiral spring 4 often encloses when loosening, the increase causing spring interfacial friction towards one side bias can not be produced, ensure that moment of torsion exports stable.
The present invention uses external force that mandrel is rotated in the counterclockwise direction, at this moment the contact-type flat spiral spring be fixed on reel will be wrapped on mandrel, when external force disappears, contact-type flat spiral spring will be with moving mandrel to rotate clockwise, and in rotation process, keep stable moment of torsion to export.
