Description
Technical field
This utility model belongs to Magnetic drive field, particularly permanent-magnet eddy current transmission.
Background technology
Permanent-magnet eddy current transmission is the practical technique in recent years 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.There are overload situations in a lot of transmission machinery in start-up course, at this moment need to reduce rotating speed
Prevent from working overloadingly, be all to solve this problem using converter plant or fluid coupling device in the past.With these mechanical shaft couplings
Arrangements for speed regulation are compared, and permanent magnet clutch is in reliability, adaptability, vibration isolating effect, service life and soft start and overload protection etc.
All many-sides have advantage.Realizing these advantages in permanent magnet clutch work process needs between drive end and driven end predetermined
In the range of slide axially to adjust spacing, be all the machine that complex adjustment spacing is equipped with permanent magnet clutch at present
Structure and executor completing, not only selling at exorbitant prices, also make troubles to actual installation practice.
Content of the invention
The technical problem that this utility model solves is to provide a kind of cylindrical permanent shaft coupling, and it is convenient in work process to have
Adjustment drive end and driven end spacing function within a predetermined range, this permanent magnet clutch price is relatively low, installation operation
Relative ease.
For solve above-mentioned technical problem, design a kind of cylindrical permanent shaft coupling, including driving shaft, drive end, driven end,
Driven shaft, driving shaft is driven by motor, and driven shaft connects load, the permanent magnetism on the cylinder type conductor on drive end and driven end cylinder
Body is correspondingly arranged with a gap.Active shaft end is furnished with sliding axle, and sliding axle is fixedly connected with drive end and can be in limited range
Inside slide axially, have static sliding seat to be fixed on equipment simultaneously, slip cap therein and the bearing block being fixed on sliding axle
Between be configured with bearing, bearing can bear bi-directional axial load, and drive end can be driven when slip cap slides axially to slide therewith.
Configuration slip spacer pin on described sliding axle and the slip spacing hole collective effect on driving shaft can be ensured master
Slide in predetermined axial scope in moved end.
Can be by the axle of the paired drive end of location hole group being designed with described slip cap on alignment pin and static sliding seat
To detent mechanism.
Working condition is such：Relative position residing for drive end shown in Fig. 3 and driven end is in parking or rated power
When lower.It is to prevent from overloading when equipment starts, drive end and driven end spacing phase can be adjusted by axial positioning mechanism
Away from more farther out, between the permanent magnet on cylinder type conductor and driven end cylinder on such drive end, electromagnetic induction region is shortened,
Transmitting torque decreases, and can avoid the generation of overflow operating.Start-up course progressively adjusts nearly drive end and driven end spacing,
Until reaching steady operation position under rated power it is ensured that start-up course overloading free situation.
The beneficial effects of the utility model are to provide a kind of cylindrical permanent shaft coupling, have convenient in work process adjustment
Drive end and driven end spacing function within a predetermined range, this cylindrical permanent shaft coupling price is relatively low, installs behaviour
Make relative ease.

Specific embodiment
The shaft coupling of this utility model cylindrical permanent shown in Fig. 3, including driving shaft 3, drive end 1, driven end 2, driven shaft
4, driving shaft 3 is driven by motor, and driven shaft 4 connects load.Cylinder type conductor on drive end 1 and the permanent magnetism on driven end 2 cylinder
Body is correspondingly arranged with a gap.Driving shaft 3 end is furnished with sliding axle 31, and sliding axle 31 is fixedly connected with drive end 1 and can have
Slide axially in the range of limit, have static sliding seat 5 to be fixed on equipment simultaneously, slip cap 7 therein be fixed on sliding axle 31
On bearing block 8 between be configured with bearing 6, bearing 6 can bear bi-directional axial load, can drive when slip cap 7 slides axially
Drive end 1 slides therewith.On sliding axle 31, configuration slip spacer pin 33 and slip spacing hole 32 collective effect on driving shaft 3 are protected
Card drive end 1 slides in predetermined axial scope.Location hole on alignment pin 72 and static sliding seat 5 is designed with slip cap 7
The axial positioning mechanism of 71 groups of paired drive ends 1.
It should be noted that those skilled in the art can be predicted for the described technical problem of solution according to professional technique right
Equivalent substitute that the present embodiment is done or obvious modification are all within the scope of present patent application protection.
Join for the innovation and creation collar plate shape permanent magnetism that the permanent magnet clutch basic structure of prior art collar plate shape shown in Fig. 1 is done
