Abstract
The utility model relates to a magnetic transmission device, comprising a driving wheel and a driven wheel which is arranged on the same shaft with the driving wheel at interval. A permanent magnet is embedded on neighboring faces of the driving wheel and the driven wheel. The utility model adopts a magnetic force to transmit a torque, which does not pierce a casing, thus not wearing and also not causing leakage to result in transmitting the torque. As a load is flexibly connected with a motor by virtue of the magnetic force, then a start impulse is reduced and a soft start is realized and the motor cannot be damaged once the load fails suddenly. And mechanical seal parts are displaced, not only is cost saved but also maintenance trouble is eliminated. An absolute co-axial is not required by the utility model, the installation is convenient, and the structure is simplified. When a cooling compressor is used, the motor can be moved to the outside of the compressor, which displaces a special enamel insulated wire used by the original motor to resist a cooling medium; and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of actuating unit, particularly a kind ofly transmits the device of moment of rotation with magnetic force, is mainly used in transmitting torque in airtight or container that liquid is close, as washing machine etc.
Background technique
Existing in the close container of liquid the equipment of (or outside) transmitting torque, as washing machine, water pump compressor etc., all adopt the method for mechanical seal, its shortcoming is can cause seal failure after the sealing material wearing and tearing, as washing machine, water pump, often occur leaking, cause burn-down of electric motor, water resource waste.
Summary of the invention
The purpose of this utility model just provides a kind of magnetic drive device that does not destroy the seal container housing.
The technical solution of the utility model is: comprise driving wheel and coaxial alternate and the driven wheel put is embedded with permanent magnet at both adjacent surfaces with it.
The utility model passes square by the magnetic force transmission, can not wear out the housing of container, so do not produce wearing and tearing, can not cause leaking because of driving torque.Owing to connect by magnetic force is soft between load and the motor, reduce to start and impact, realize soft start, and under the suddenly stuck situation of load, also can not damage motor; Save mechanical sealing element, both saved cost, also removed the trouble of safeguarding from; Need not definitely coaxial, easy for installation; Simplified structure; Motor can move on to outside the compressor body when refrigeration compressor is used, and changes the special enameled cable that the past motor uses anti-refrigeration agent, has reduced cost.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation.
Fig. 2 is another embodiment's of the utility model a structural representation.
Embodiment
Referring to Fig. 1, this embodiment comprises casing 1, interior wheel 2 and foreign steamer 3, one that is somebody's turn to do interior foreign steamer 2,3 as driving wheel, another is as driven wheel, there is the pit 4 that matches with interior wheel 2 profiles at end middle part at foreign steamer 3, is casing 1 between the two, leaves gap 5 between this casing 1 and interior foreign steamer, the other end of foreign steamer 2,3 respectively has wheel shaft 6 in this, evenly is embedded with 2-10 piece permanent magnet 7 in the relative circumferential surface of interior foreign steamer; Foreign steamer 2,3 equal rotational support are on casing 1 in described.
The wheel shaft 6 of wheel 2 (or foreign steamers 3) is connected with the output shaft of power engine (as motor) in of the present utility model, another wheel shaft 6 is connected with load, interior foreign steamer 2,3 equal rotational support or are supported on the casing 1 (frame) by load (or motor) on casing 1 (or the frame of fixedlying connected with it).When the foreign steamer 3 that is connected with motor (or interior wheel 2) rotated, the mutual magnetic force by permanent magnet 7 drove interior wheel 2 (or foreign steamer 3) rotation that is connected with load, has realized the transmission of power.
Referring to Fig. 2, another embodiment of the present utility model is that two wheels 2 are coaxial relative with 3, passes the housing 1 of container between the two; Its working principle is the same.
Claims (1)
1, a kind of magnetic drive device is characterized in that: comprise driving wheel and coaxial alternate and the driven wheel put is embedded with permanent magnet at both adjacent surfaces with it.
