Abstract
The utility model relates to a compoundable magnetic driving device, which is a mechanism driving technology, in particular to a non-touching driving device formed by magnetic materials. The external ring point of the initiative shaft end face disc connected with an electromotor is enchased interlacing with radiation-distributed sector magnets, between which is filled with anti-magnetism materials, and a passive shaft whose end face disc is provided with a sector magnet is symmetrically arranged in an insulating sleeve corresponding to the initiative shaft end face disc. Because the utility model adopts still sealing coupling with a non-touching magnet instead of the original complex shaft sealing structure, the phenomenon of leaking is avoided to be happened, and a medium is magnetism processed. The utility model has the advantages of simple structure, easy processing, and is suitable for mechanism movement under the condition of absolute sealing.
Description
The utility model relates to mechanical transmissioning technology, specifically a kind of noncontact transmission device that is made of magnetic material.
Common machine driving is to adopt directly mechanical structure such as connection or shaft coupling of power transmission shaft, but under many occasions, can run into sealing problem as departments such as vacuum, chemical industry, oil, medicine, owing to adopt the mechanical shaft seal structure not overcome the gap of rotating ring and stationary ring, therefore can not eradicate the seepage phenomenon.As seepage occurring, can cause serious consequence for inflammable, explosive, strong corrosive medium.
The purpose of this utility model provides and a kind ofly can overcome above-mentioned shortcoming, eradicates the non-contact magnetically transmission device of seepage phenomenon.
The utility model technical essential is:
Link to each other with the motor outer shroud place of driving shaft (1) end face disk (2), the staggered fan-shaped magnetic patch (3) that is inlaid with radiation profiles, magnetic patch is filled diamagnetic material between (3); In the separation sleeve (4) corresponding, be provided with the driven axle (6) of the fan-shaped magnetic patch of end face band (5) disk symmetrically with driving shaft (1) end face disk.Inside at separation sleeve (4) can compoundly be provided with tubular magnetic treatment device (7), and it is applied to medium after magnetic treatment, can produce beneficial effect (improving reaction speed, combustion efficiency) in some occasions (as scale removal, wax removal etc.).
The utility model can be avoided the seepage phenomenon to take place, and simultaneously medium carried out magnetic treatment owing to be to adopt static seal and non-contacting magnetic lotus root to close to replace original complicated shaft seal structure.It is simple in structure, is easy to processing, is suitable for the machine driving under the positive confinement condition.
