Abstract
The utility model relates to the technical field of articles for daily life, in particular to a magnetic powder brake, comprising a rotating shaft, an upper cover body, a lower cover body and a coil, wherein the lower cover body is installed in the upper cover body to form a chamber which is internally provided with a sealing ring; the rotating shaft penetrates through rotating shaft holes of the upper cover body and the lower cover body; the rotating shaft is sheathed with a bearing which is fixed in the shaft holes of the upper cover body and the lower cover body; the rotating shaft is provided with a rotor; the periphery of the rotor is sheathed with a non-magnetoconductivity ring body and the coil in sequence; and the non- magnetoconductivity ring body, the upper cover body, the lower cover body and the sealing ring form a magnetic powder chamber for containing magnetic powder. The magnetic powder brake has scientific and simple structural design, small volume, convenient use and installment, multi-direction installment and no position limitation.
Description
Technical field:
The utility model relates to technical field of living goods, refers in particular to magnetic powder brake.
Background technique:
Magnetic formula break is a kind of automatic control unit of superior performance.It is a working medium with the magnetic, is control device with the exciting curent. reach sliding purpose along control change braking or change transmitting torque.Its output torque and exciting curent are good linear relationship makes the break torque sliding along changing with the change of electric current and voltage. and have sensitive speed of response advantages of simple structure and simple.Be widely used in printing, the relevant tension automatic control system that batches emptying device such as packing, papermaking and paper product processing, weaving, printing, electric wire, cable, rubber leather, metallic foil processing.
In the magnetic powder brake that generally uses at present, on structural design, all there is certain problem, its complex structural designs, volume is big, thereby heavy, use very inconvenient, and the restriction of magnetic and structure, can only level install, use is not extensive, can not satisfy usage requirement.
The model utility content:
The purpose of this utility model is at the deficiencies in the prior art, and magnetic powder brake is provided, and its scientific structure design is simple, and volume is little, easy to install and use, can multi-facetedly install, and is not subjected to position limit.
For achieving the above object, the utility model adopts following technological scheme, it comprises rotating shaft, upper cover body, lower cover, coil, lower cover is installed in and forms a cavity in the upper cover body, be provided with seal ring in the cavity, rotating shaft is arranged in the rotary shaft hole of upper cover body, lower cover, be arranged with bearing in the rotating shaft, bearing fixing is in upper cover body, lower cover axis hole, rotating shaft is provided with rotor, the periphery of rotor is arranged with non-magnetic ring body, coil successively, and non-magnetic ring body, upper cover body, lower cover, seal ring form the magnetic chamber of ccontaining magnetic.
Described rotor, non-magnetic ring body, coil are positioned at upper cover body, lower cover forms a cavity.
The external card of the two ends of described rotating shaft and upper cover body, lower cover is provided with jump ring.
Evenly offer through hole on the described rotor.
The utility model beneficial effect is: in the rotary shaft hole of lower cover, be arranged with bearing in the rotating shaft, bearing fixing is in upper cover body, lower cover axis hole, rotating shaft is provided with rotor, and the periphery of rotor is arranged with non-magnetic ring body, coil successively, and non-magnetic ring body, upper cover body, lower cover, seal ring form the magnetic chamber of ccontaining magnetic, its scientific structure design is simple, volume is little, easy to install and use, can multi-facetedly install, and is not subjected to position limit.
Description of drawings:
Fig. 1 is a sectional view of the present utility model;

Embodiment:
See Fig. 1,2, shown in 3: the utility model comprises rotating shaft 1, upper cover body 2, lower cover 3, coil 4, lower cover 3 is installed in and forms a cavity in the upper cover body 2, be provided with seal ring 6 in the cavity, rotating shaft 1 is arranged in upper cover body 2, in the rotary shaft hole of lower cover 3, be arranged with bearing 8 in the rotating shaft 1, bearing 8 is fixed on upper cover body 2, in lower cover 3 axis holes, rotating shaft 1 is provided with rotor 5, the periphery of rotor 5 is arranged with non-magnetic ring body 9 successively, coil 4, non-magnetic ring body 9, upper cover body 2, lower cover 3, seal ring 6 forms the magnetic chamber 10 of ccontaining magnetic, and magnetic is equipped with in magnetic chamber 10.
Described rotor 5, non-magnetic ring body 9, coil 4 are positioned at upper cover body 2, lower cover 3 forms a cavity.
The external card of the two ends of described rotating shaft 1 and upper cover body 2, lower cover 3 is provided with jump ring 7.
Evenly offer through hole 51 on the described rotor 5.
Magnetic is subjected to current affects system to present pencil and is adsorbed in rotor 5 surfaces, and this magnetic is subjected to current affects to produce the torque of magnetic and then brake rotors 5. this rotor 5 gets final product the rotation of synchronous braking rotating shaft 1, and non-magnetic ring body 9 belongs to the non-magnetic characteristic of conduction, and the magnetic force that magnetic produced that is adsorbed on the rotor 5 is not leaked.
The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
