Description
Technical field
The invention belongs to Magnetic drive field, particularly permanent-magnet eddy current transmission.
Background technology
Permanent-magnet eddy current transmission is the practical technique the most just risen, and permanent magnet clutch is one of major product, Fig. 1 and Tu
2 is two kinds of basic structures of permanent magnet clutch, i.e. collar plate shape permanent magnet clutch and cylindrical permanent shaft coupling.Permanent magnet clutch is all
There are speed governing or reduction of speed effect.A lot of transmission machinery exist in start-up course or in running and transship or the fluctuation of load
Situation, at this moment needs to reduce or change bearing axle rotating speed and prevents overwork, be the most all to utilize converter plant or fluid power
Coupling device solves this problem.With these machinery shaft coupling arrangements for speed regulation compared with, permanent magnet clutch reliability, adaptability, every
All many-sides such as effect, service life and soft start and overload protection etc. of shaking have advantage.Permanent magnet clutch work process realizes
These advantages need to slide axially in preset range between drive end and driven end to adjust spacing, are the most all at permanent magnetism
The mechanism and the executor that are equipped with complex adjustment spacing on shaft coupling complete, not only selling at exorbitant prices, also give reality peace
Dress operation is made troubles.
Summary of the invention
Present invention solves the technical problem that and be to provide a kind of collar plate shape permanent magnet clutch, have in work process and automatically adjust
Drive end and driven end spacing function in preset range, this permanent magnet clutch price is relatively low, installs operation relatively
Easy.
For solving above-mentioned technical problem, a kind of collar plate shape permanent magnet clutch of design, including driving shaft, drive end, driven end,
Driven shaft, driving shaft is by driven by motor, and driven shaft connects load, the collar plate shape conductor on drive end and the permanent magnetism on driven end disk
Body is correspondingly arranged with a gap.Driving shaft end is furnished with sliding axle, and sliding axle is fixing with drive end to be connected and can be in limited range
Inside sliding axially, have stationary spring seat to be fixed on equipment simultaneously, spring mechanism therein is kept actively by thrust bearing
End applies thrust.
Guarantee master can be jointly acted on the slip spacing hole on driving shaft by configuring slip spacer pin on described sliding axle
Slide in the range of making a reservation for axially in moved end.
The described stationary spring seat being fixed on equipment can be designed as central column, it is evenly distributed with some springs
Mechanism.
It is to stop or rated power that working condition is such that relative position residing for drive end shown in Fig. 3 and driven end
The when of lower.When equipment is because starting overload or running into unexpected overload, because resistance increase causes between drive end and driven end
Speed discrepancy increases, and this can cause the induced current in the collar plate shape conductor on drive end to increase, which again increases drive end and from
Repulsive force between moved end, then the distance between drive end and driven end becomes big, thus permanent magnet clutch actual transfer moment of torsion
Decreasing, after after starting, gradually steady or unexpected overload is got rid of, drive end applies power at spring mechanism by thrust bearing
Effect under, the normal position under rated power can be gradually restored to.In whole work process, it is to avoid overflow operating
Occur.
A kind of collar plate shape permanent magnet clutch of offer is provided, has in work process and automatically adjust actively
End and driven end spacing function in preset range, this collar plate shape permanent magnet clutch price is relatively low, installs operation phase
To simplicity.

Detailed description of the invention
Collar plate shape permanent magnet clutch of the present invention shown in Fig. 3, including driving shaft 3, drive end 1, driven end 2, driven shaft 4, main
Moving axis 3 is connect load by driven by motor, driven shaft 4.Collar plate shape conductor on drive end 1 has with the permanent magnet on driven end 2 disk
It is correspondingly arranged with gap.Driving shaft 3 end is furnished with sliding axle 31, and sliding axle 31 is fixing with drive end 1 to be connected and can be at limited model
Slide axially in enclosing.Stationary spring seat 5 is fixed on equipment, and spring mechanism 51 therein is kept actively by thrust bearing 6
End 1 applying thrust.Configure slip spacer pin 33 on sliding axle 31 and jointly act on guarantee master with the slip spacing hole 32 on driving shaft 3
Slide in the range of making a reservation for axially in moved end 1.The stationary spring seat 5 being fixed on equipment is designed as central column, and it is uniformly distributed
There are 4 sleeve spring mechanisms 51.
It should be noted that according to professional technique, those skilled in the art are that the described technical problem of solution can predict right
The equivalent that the present embodiment is done substitutes or obvious modification is all within the scope of present patent application is protected.
The innovation and creation cylindrical permanent connection done for the shaft coupling basic structure of prior art cylindrical permanent shown in Fig. 2
Axial organ is because summarizing in the independent claims of the present invention, and applicant will propose separate case application.
