Abstract
The invention relates to a rotating shaft and particularly relates to a rotating shaft with a damping system. The rotating shaft comprises a central shaft, at least one clamp nut, at least one bearing spacer, at least one rotating arm, and at least one rotating sheet capable of being connected with the rotating arm. The rotating shaft with the damping system is characterized by further comprising at least one group of butterfly-type springs; and the compression stress of the butterfly-type springs is adjusted to control the axial pressure, so that the adjustable rotating friction force needed by the rotation in the peripheral direction is generated. The butterfly-type springs can be replaced by other springs. According to the rotating shaft with the damping system, the effect of stable rotation can be achieved.
Description
Technical field
The present invention relates to a kind of rotating shaft, relate in particular to a kind of rotating shaft with damped system, is a kind of electronic product component, belongs to electronic product mechanical technique application.
Background technique
Existing use for electronic products rotating shaft mainly contains two kinds, and a kind of rotating shaft is to utilize cam and spring structure, realizes forwarding another special position to from a position, and it is discontinuous that the pilot process rotation appears in this kind rotating shaft in use easily, and unstable; Because the inertia of mechanical motion can produce certain impact force, this impact force can cause damage to electronic product again.Another kind of common use for electronic products rotating shaft is to utilize rotating shaft and nut locking and fastening system, though this kind rotating shaft can realize continuous rotation, owing to adopt the nut locking; Screw damages easily in the rotation process, is not durable, and nut is prone to get loose; The load-carrying surface easy damaged causes rotating unstable.
Summary of the invention
Technical problem to be solved by this invention provides a kind of rotating shaft with damped system, can realize the steady and can regulate that product rotates.
For addressing the above problem, the present invention provides a kind of rotating shaft with damped system, comprises central shaft; At least one tightening nut; At least one bearing pad and at least one cursor, and at least one can connect the rotary piece of cursor, it is characterized in that: also comprise at least one group of dish formula spring; Through the compressive force of regulating dish formula spring come Control Shaft to pressure, and with the adjustable rotation friction on this required circumferencial direction that rotates.
Wherein, said dish formula spring is provided with for the composite combined mode, is involutory compound mode or superimposed compound mode especially.
Further, said cursor and rotary piece are fixed together, and also can synthesize parts, as the extension of rotary piece.
For further optimizing effectiveness, can between bearing pad and rotary piece, add damping oil.
According to a further aspect in the invention, one of them tightening nut can be fixed with central shaft.
As location and supporting dish formula spring, on central shaft, be provided with a step especially, be used to locate and support a side of dish formula spring.
Particularly, the rotating shaft among the present invention, said dish formula spring is 2 groups, and said tightening nut is 2, and said bearing pad is 3, and bearing pad is arranged on the both sides of dish formula spring and rotary piece.
Spring among the present invention is not limited to dish formula spring, also comprises the spring of other type.
Description above according to the present invention; The accessible beneficial effect of the present invention does; Damped system of the present invention uses one group of dish formula spring to produce adjustable axial pressure; And, reached the effect that produces stable rotation with the adjustable rotation friction on this required circumferencial direction that rotates, make rotation more stable.

Fig. 1 is the three-dimensional perspective with rotating shaft of damped system of the present invention;
Fig. 2 is an explosive view of the present invention;
Fig. 3 is an axial section of the present invention;
Fig. 4 is a use scheme of installation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details.
Following examples only are used for technological scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
Fig. 1 is the three-dimensional perspective with rotating shaft of damped system of the present invention, has shown surface structure of the present invention.Fig. 3 is an axial section of the present invention, has shown the mutual assembly relation of each part among the present invention.Concrete structure of the present invention is formed like Fig. 2 and shown in Figure 4, and of the present invention have the damped type rotating shaft and comprise 4, two tightening nuts 1 of 2, one groups of dish formulas of central shaft spring and 8, a plurality of bearing pads 3,5,7 and a rotary piece 6 that can be connected cursor.Two cursor A shown in Figure 4 and B, cursor A and B are two adjutages of rotating shaft, also can be described as the extension of rotary piece.Cursor can be fixed together with rotary piece, also can synthesize parts.
Above-mentioned support plate has protective action, and wherein bearing pad 5 and 7 can also be as two damping areas (rubbing surface), so the position relative fixed, and quantity can not limit.
In the present invention, central shaft 2 can be fixing with tightening nut 1, and cursor A also can be used as fixed arm simultaneously, promptly fixes with central shaft.Have positioning step to be used to locate cursor on the central shaft 2, tightening nut 1 is used to lock cursor.
A step is arranged on the central shaft 2, be used to locate and support a side of dish formula spring 4, middle 3, one effects of bearing pad are support spring power, and another effect is that protection central shaft 2 does not receive spring to rotate the damage that is produced.
Dish formula spring assembly 4 usefulness the spring of two groups of involutory combinations, it is by four dish formula spring involutory compositions, promptly in use one group of dish formula spring can concave surface to the concave surface setting, also can convex surface to the convex surface setting.Dish formula spring can also adopt composite combined modes such as superimposed compound mode to be provided with.Through material to dish formula spring, size, the design of shape and number can produce stable and adjustable pressure.
More stable in order to make in the rotation process, between bearing pad 5,7 and rotary piece 6, add damping oil, utilize the viscosity and the mechanical stability of damping oil, make damping torque stable, stability of rotation.
It should be noted that; The above is merely preferred embodiment of the present invention; Be not so limit scope of patent protection of the present invention, the present invention can also carry out the improvement of material and structure to the structure of above-mentioned various component, or adopts the technical equivalents thing to replace.So the equivalent structure that all utilizations specification of the present invention and diagramatic content are done changes, or directly or indirectly apply to other correlative technology fields and all in like manner all be contained in the scope that the present invention contains.
