Description
Technical field
The utility model relates to the magnetorheological coupling of a kind of ball formula.
Background technique
Traditional machenical coupling exist impact, inertia is big, fretting wear and heating is serious, working life short.Defectives such as control inconvenience.In recent years; The magnetic flow liquid technical development is rapid; The magnetic flow liquid coupling can overcome the shortcoming of traditional mechanical formula coupling; Through changing the just size of control apparatus transmitting torque easily of size of current, control is simple, make things convenient for, so the application of magnetic flow liquid coupling on the transmission engineering more and more widely.Yet present existing magnetic flow liquid coupling will be exported high pulling torque, and volume just requires bigger, therefore, is not suitable in narrow space, working, and has certain narrow limitation.
The model utility content
The purpose of the utility model is to provide a kind of ball formula magnetorheological coupling, its compact structure, and volume is less, and output torque is bigger, and the coupling that has solved other type can not be in the problem of work in narrow space.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme: the utility model discloses the magnetorheological coupling of a kind of ball formula, comprise driving shaft; One end of said driving shaft is connected with the active ball, has annular groove on the said active ball, establishes field coil in the said annular groove; Said field coil is connected with outer terminal circuit through lead; Said field coil is provided with outward at a distance from magnetosphere, and said driving shaft is provided with bearing, and said bearing closely is connected with driven ball; Said driven ball is connected with an end of driven shaft; Said driven ball is formed by connecting two identical hollow hemisphere, is provided with the gap between said active ball and the driven ball, is provided with magnetic flow liquid in the gap.The utility model has the advantages that: compact structure, volume is less, can be applicable to small space, and than the coupling of other type, output torque is bigger, and is easy to control.
Preferably, an end of said driving shaft is with initiatively ball is through being welded to connect, and said driven ball and driven shaft are also through being welded to connect; Easy to process, use reliable.
Preferably, said active ball adopts georama; Economical with materials reduces cost.
Preferably, the outside of said field coil is provided with at a distance from magnetosphere; Separated magnetic effect.
Compared with prior art, the utility model has the advantages that: the magnetorheological coupler structure of this ball formula is compact, and volume is less, can be applicable to small space, and than the coupling of other type, output torque is bigger, and is easy to control.
Description of drawings
Fig. 1 is the structural representation of the magnetorheological coupling of a kind of ball formula of the utility model.
Embodiment
Consult the embodiment of Fig. 1 for the magnetorheological coupling of a kind of ball formula of the utility model, the magnetorheological coupling of a kind of ball formula comprises driving shaft 1; Said driving shaft 1 is connected with active ball 6 through welding, and said active ball 6 is hollow spheress, has annular groove on its surface; Be provided with in the annular groove at a distance from magnetosphere 4 and field coil 5; Described field coil 5 is connected with the outer end control circuit through the lead line, and said driving shaft 1 is provided with bearing 2, and said bearing 2 is connected with said driven ball 3; Said driven ball 3 is to be formed by connecting through bolt two identical hollow hemisphere; Said driven ball 3 and driven shaft 7 are provided with the gap through being welded to connect between said active ball 6 and the driven ball 3, are provided with magnetic flow liquid 8 in the gap.
When external control circuit was in open-circuit condition, during promptly with lead no current that field coil 5 links to each other, field coil 5 did not produce excitation; At this moment, initiatively 8 of magnetic flow liquids between ball 6 and the driven ball 3 have common liq character, when power reaches driving shaft 1; Driving shaft 1 drives initiatively ball 6 rotations, because this moment, magnetic flow liquid 8 was equivalent to common liq, the moment of torsion that can be delivered to driven ball 3 is very little; Said driven ball 3 does not rotate basically, and at this moment, coupling is in the disconnected phase.
When external control circuit alived, when the lead that promptly links to each other with field coil 5 had electric current, field coil 5 produced excitation, at this moment; Initiatively the viscosity of the magnetic flow liquid 8 between ball 6 and the driven ball 3 strengthens, and electric current is strong more, and viscosity is big more, when power reaches driving shaft 1; Driving shaft 1 drives initiatively ball 6 rotations, because the viscosity of magnetic flow liquid 8 is very big at this moment, therefore; The moment of torsion that can be delivered to driven ball 3 is also very big, and when electric current was enough big, the viscosity of magnetic flow liquid 8 was also enough big; And the final type solid that forms, the moment of torsion that is delivered to driven ball 3 is also very big, and driven ball 3 outwards transmits moment of torsion through driven shaft 7 again.When needs transmit the moment of torsion of different sizes, as long as regulate outer end circuital current size.The magnetorheological coupling of the novel ball formula of this reality because of its compact structure, volume is less, output torque is bigger, automation is high, so can be applicable to small space.
The above is merely the specific embodiment of the utility model, but the technical characteristics of the utility model is not limited thereto, and any those skilled in the art is in the field of the utility model, and the variation of being done or modify all is encompassed among the claim of the utility model.
