Description
Technical field
The present invention relates to a kind of coupler more particularly to a kind of liquid mixed couplers of magnetic.
Background technology
It is without damage in starting or overload to be effectively protected motor and working machine when transmitting high-power, reduce machine
Device failure rate, elongated component and complete machine service life reduce maintenance cost and downtime；Between motor and working machine,
Transmission device flexible is needed to configure, to eliminate shock and vibration, improves starting performance, and realize overload protection.
Currently used flexible gearing has fluid coupling and magnetic coupling, can preferably realize and slow down startup punching
Hit and be isolated torsional oscillation, overload protection, load delay slowly start and energy saving etc..But for transmitting large-power occasions, fluid power
Coupler volume is bigger, transmission efficiency is low, and dynamic response is slow；Equally when transmitting relatively high power, magnetic coupling volume
Also bigger, but dynamic response is very fast.When the volume of flexible gearing is larger, many occasions are unfavorable for installing and using.
Invention content
The object of the present invention is to provide a kind of relative volume is smaller, it can realize and slow down startup impact and isolation torsional oscillation, overload
The flexible gearing of the functions such as protection, the slow startup of load delay.
Used technical solution is the present invention to solve above-mentioned technical problem：Devise a kind of liquid mixed coupling of magnetic
Device, the coupler are made of driving shaft, turbine, shell, copper rotor, permanent magnet, pump impeller, driven shaft.Driving shaft by shell with
Pump impeller is affixed, and when motor drives driving shaft rotation, pump impeller stirs coupler intracavity liquid, under the influence of centrifugal force, chamber
Interior liquid is accelerated from the smaller tunnel inlets of radius, and is thrown at the larger runner mouth of radius, is added to the momentum of liquid
Greatly, turbo blade is rushed at higher speed and pressure in pump impeller exit liquid stream, release liquid kinetic energy pushes turbine rotation to do
Work(realizes that turbine converts liquid kinetic energy to mechanical energy；After the kinetic energy of liquid reduces, by turbine under liquid-driving behind
Pump impeller is exited into, then starts new energy conversion；At the same time, copper rotor is rotated with shell, and copper rotor is in cutting permanent magnetism
Inducing eddy-current is generated when the magnetic line of force of body, and the active force between the magnetic field of inducing eddy-current and the magnetic field of permanent magnet realizes
Torque between motor and working machine transmits.So in cycles, it inputs with output in the case where not being mechanically connected directly,
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：Magnetic liquid mixed coupler comprehensive utilization fluid power and magnetic force passing power, volume compared with
Small, compact-sized, transmission efficiency, dynamic response are very fast, have and slow down startup impact and isolation torsional oscillation, overload protection, load
Delay slowly starts and the functions such as energy saving, easy to install and use.
