Description
Technical field
The present invention relates to a kind of coupler more particularly to a kind of axial charging combined-type magnetic liquid couplers.
Background technology
When complex working condition transmits high power load, being effective protection motor and working machine, improve the startability of motor
Can, motor and working machine failure rate are reduced, extends the service life of complete machine.It is usually filled in motor with working machine by Flexible Transmission
It puts to connect, shock and vibration is eliminated with this, protection motor and working machine are without damage in overload, reduce maintenance cost.
Currently used flexible gearing has fluid coupling and magnetic coupling.For high-power fluid coupling,
Volume is big and transmission efficiency is low, and dynamic response is slow；Similarly for high-power magnetic coupling, volume is also larger, but dynamic
Response is very fast.Patent application No. is 201610683067.9 proposes a kind of liquid mixed coupler of magnetic, can realize to slow down and open
Move the flexible gearing for impacting and being isolated the functions such as torsional oscillation, overload protection, the slow startup of load delay.Since permanent magnet is along whirlpool
Hub cap is radially arranged so that the coupler radial dimension is larger, makes troubles to installing and using.
Invention content
The object of the present invention is to provide a kind of axial chargings, and diametrically size is smaller, can realize slow down startup impact and
The flexible gearing of the functions such as torsional oscillation, overload protection, load delay slow start is isolated.
The used to solve above-mentioned technical problem technical solution of the present invention is：Devise a kind of combined-type magnetic liquid coupling
Device, the coupler is by driving shaft, shell, copper rotor, permanent magnet, aluminium dish, turbine, pump impeller, blade, driven shaft, motor, work
Machine.Motor is affixed with driving shaft, and driving shaft is affixed with shell, and shell is affixed with pump impeller；Driven shaft is affixed with turbine, aluminium dish and whirlpool
It takes turns affixed, permanent magnet is evenly arranged in aluminium dish axial end face, along turbine radial arrangement blade；When motor drives driving shaft rotation
When, aqueous agitation that pump impeller will be filled in coupler intracavitary, liquid under the influence of centrifugal force, from the smaller runner of intracavitary radius
Entrance is accelerated, and is thrown at the larger runner mouth of radius, so as to liquid momentum increase, pump impeller exit liquid stream with compared with
High speed and pressure rushes at turbo blade, and release liquid kinetic energy pushes turbine rotation acting, realizes that turbine turns liquid kinetic energy
Turn to mechanical energy；After the kinetic energy of liquid reduces, pump impeller is exited by turbine under liquid-driving behind, then is started new
Energy conversion；At the same time, motor is affixed with driving shaft, and copper rotor is affixed with shell, and driving shaft drives shell and copper rotor
Rotation, copper rotor cut the magnetic line of force of permanent magnet, inducing eddy-current, the magnetic field of inducing eddy-current and permanent magnetism are generated in copper rotor
The magnetic field of body generates interaction force, drives turbine rotation, since turbine is affixed with driven shaft, so as to drive driven shaft, realizes
The transmission of torque between driving shaft and driven shaft.So in cycles, driving shaft connects with driven shaft directly not mechanical
In the case of connecing, under the comprehensive function of fluid power and magnetic force, realize that the torque between motor and working machine transmits.
The beneficial effects of the invention are as follows：The combined-type magnetic liquid coupler comprehensively utilizes fluid power and magnetic force passing power, radially
Relative size is smaller, compact-sized, dynamic response is fast, has to slow down starting-impact and torsional oscillation, overload protection and load is isolated and prolong
When the functions such as slow start, it is easy to install and use.
