Abstract

The utility model relates to a rotating shaft, and particularly relates to the rotating shaft with a damping system. The rotating shaft with the damping system comprises a centre shaft, at least one fastening nut, at least one supporting gasket and at least one rotating arm as well as at least one rotating plate which can be connected with the rotating arm; and the rotating shaft with the damping system is characterized in that the rotating shaft also comprises at least one group of disc type springs, the axial pressure is controlled by adjusting the compressing forces of the disc type springs, and accordingly an adjustable rotating frictional force required for rotation in the peripheral direction is generated. The disc type springs can be replaced by other springs. The rotating shaft with the damping system can achieve the effect of stable rotation.

Description

A kind of rotating shaft with damped system

Technical field

The utility model relates to a kind of rotating shaft, relates 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 easily gets loose, the load-carrying surface easy damaged causes rotating unstable.

The model utility content

Technical problem to be solved in the utility model provides a kind of rotating shaft with damped system, can realize that product rotates steadily and can regulate.

For addressing the above problem, the utility model provides a kind of rotating shaft with damped system, comprise central shaft, at least one tightening nut, at least one bearing pad and at least one cursor, and the rotary piece that at least one can the connection of rotating arm is characterized in that: also comprise at least one group of dish formula spring, by the compressive force of regulation disc formula spring come Control Shaft to pressure, and with the adjustable rotation friction on this required circumferencial direction that rotates.

Wherein, described dish formula spring is that the composite combined mode arranges, and is involutory compound mode or superimposed compound mode especially.

Further, described 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 on the other hand of the present utility model, one of them tightening nut can be fixed with central shaft.

As location and supporting dish formula spring, be provided with a step at central shaft especially, be used for a side of location and supporting dish formula spring.

Particularly, the rotating shaft in the utility model, described dish formula spring is 2 groups, and described tightening nut is 2, and described bearing pad is 3, and bearing pad is arranged on the both sides of dish formula spring and rotary piece.

Spring in the utility model is not limited to dish formula spring, also comprises the spring of other type.

According to the description above the utility model, the accessible beneficial effect of the utility model is, damped system of the present utility model uses one group of dish formula spring to produce adjustable axial pressure, and with the adjustable rotation friction on this required circumferencial direction that rotates, reached the effect that produces stable rotation, made rotation more stable.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

Fig. 1 is the three-dimensional perspective with rotating shaft of damped system of the present utility model, has shown surface structure of the present utility model.Fig. 3 is axial section of the present utility model, has shown the mutual assembly relation of each part in the utility model.Concrete structure of the present utility model forms such as Fig. 2 and shown in Figure 4, and of the present utility model have damping rotating shafts and comprise 2, one groups of dish formulas of central shaft spring 4, two tightening

nuts

1 and 8,3,5,7 and one of a plurality of bearing pads can the connection of rotating arm rotary piece 6.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 is relatively fixing, and quantity can not limit.

In the utility model, central shaft 2 can be fixing with tightening nut 1, and cursor A also can be used as fixed arm simultaneously, namely fixes with central shaft.Have positioning step to be used for the locating rotation arm on the central shaft 2, tightening nut 1 is used for the locking cursor.

A step is arranged on the central shaft 2, be used for a side of location and supporting dish formula spring 4, middle 3, one effects of bearing pad are support spring power, and another effect is that protection central shaft 2 is not subjected to spring to rotate the damage that produces.

Dish formula spring assembly 4 usefulness the spring of two groups of involutory combinations, it by four dish formula springs to being combined into, namely 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 the composite combined modes such as superimposed compound mode to arrange.By the material to dish formula spring, size, the design of shape and number can produce stable and adjustable pressure.

Bearing pad

5,7 and tightening nut 8 are fixed spring assembly and rotary piece 6 on the one hand, on the other hand rotary piece 6 are protected.

More stable in order to make in the rotation process, between

bearing pad

5,7 and rotary piece 6, add damping oil, utilize viscosity and the mechanical stability of damping oil, make damping torque stable, stability of rotation.

It should be noted that; the above only is preferred embodiment of the present utility model; be not so limit scope of patent protection of the present utility model, the utility model can also carry out to the structure of above-mentioned various component the improvement of material and structure, or adopts the technical equivalents thing to replace.So the equivalent structure that all utilizations specification of the present utility model 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 utility model contains.
