Abstract
The invention provides a coupler. A permanent magnet cover is electrified to generate a strong electromagnetic field, magnetorheological fluid serves as a force transmitting medium, a permanent magnet is selected for providing a magnetic source, the magnetorheological fluid is subjected to the curing reaction, and therefore enough dynamic shear yield stress is provided for transmitting torque. The part between a drive cylinder and a driven cylinder is filled with the magnetorheological fluid, sealing is conducted through a sealing cover, and leakage, volatilization and the like of the magnetorheological fluid are prevented. The magnetic source needed for transmission of the magnetorheological fluid is supplied through the permanent magnet cover, the permanent magnet cover is made of neodymium, iron, boron, aluminum, nickel and cobalt or ferrite materials and has an extremely high magnetic energy product and coercive force, meanwhile, the size of the permanent magnet cover is greatly reduced under the condition of the same magnetic energy through the beneficial effect of the high energy density, the structure is simplified, higher efficiency is achieved, and more energy is saved.
Description
Technical field
The present invention relates to a kind of shaft coupling.
Background technology
Magnetic flow liquid is that one presents low viscous Newtonian fluid characteristic under zero magnetic field condition；And under strong magnetic field action, then present a kind of material of the bulk properties of high viscosity, lazy flow.It is that shear yield strength and magnetic field intensity after moment, reversible and its stream become has stable corresponding relation owing to magnetic flow liquid stream under the action of a magnetic field becomes, is therefore the intellectual material of a kind of of many uses, function admirable.
Since the forties in 20th century NBS JocobRobinow be found that material this magnetic effect since, it is constantly studied by various countries scientists and engineers, relates generally to magnetic flow liquid self character and the research of application two aspects thereof.The research of magnetic flow liquid self character is mainly included its working mechanism, the composition of magnetic flow liquid, preparation and performance improvement.And the structural design to magnetic rheological liquid damper, brake, burnishing device and other transmission device and performance optimization is mainly included in its application aspect.
The present invention utilizes the special characteristics of magnetic flow liquid exactly, is applied to mechanism's design field of shaft coupling, and invents a kind of transmission performance that not only can control magnetic flow liquid transmission device well but also the shaft coupling of energy loss can be reduced.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of shaft coupling, its objective is to improve the transmission performance of shaft coupling and the loss of transmission energy can be reduced.
A kind of shaft coupling, it includes end cap, described end cap and gland are bolted to connection, it docks the passage formed for passing into lubricating oil with half liquid bath of another annular being arranged on gland to be provided with half annular liquid bath inside described end cap, described end cap is arranged below permanent magnet cover body with gland, described permanent magnet cover body is by neodymium iron boron, aluminum nickel cobalt or Ferrite Material are made, described permanent magnet cover body is provided with through hole for lubricating oil is imported in permanent magnet cover body working drum in, described working drum includes actuating cylinder and driven cylinder, it is provided with the working clearance between described actuating cylinder and driven cylinder, one end of described actuating cylinder is provided with end cap, gap between actuating cylinder and driven cylinder is closed to become and is held chamber for what deposit magnetic rheological liquid by described end cap.
Preferably, described driven cylinder is provided with coil.
Preferably, a driven shaft it is interspersed with in the middle of described driven cylinder.
Preferably, the end of described driven shaft is provided with groove.
Shaft coupling provided by the invention, it has the beneficial effects that: produce strong electromagnetic field to the energising of permanent magnet cover body, rely on magnetic flow liquid as power transmission medium, by selecting permanent magnet to provide magnetic source, make magnetic flow liquid generation curing reaction, provide enough dynamic shearing yield stress transmission moments of torsion with this, between actuating cylinder and driven cylinder, fill full magnetic flow liquid, and seal with capping, it is prevented that the leakage of magnetic flow liquid and volatilization etc..Magnetic source needed for magnetic flow liquid transmission is provided by permanent magnet cover body, permanent magnet cover body is made up of neodymium iron boron aluminum nickel cobalt or Ferrite Material has high magnetic energy product and coercivity, the advantage of high-energy-density makes permanent magnet cover body greatly reduce in the situation lower volume of equal magnetic energy simultaneously, simplify structure, more energy-efficient；Have again and can also set up coil on driven cylinder, needing less magnetic flux or requiring over adjustment electric current to control overall magnetic flux size adjustment shear stress；Have again under the effect of magnetic field of permanent magnet, magnetic-particle in magnetic flow liquid produces magnetization, and the direction along magnetic field, gap is formed magnetic linkage, due to this chain structure, considerably increase shear yield stress, rely on the transmission torque of this shear stress, making Passive part synchronous axial system under the drive of driving link, the moment of torsion of the shear stress of actuating cylinder and the magnetic flow liquid in driven cylinder gap and shaft coupling output also keeps constant；Having on driven shaft again and arrange groove, be bolted, this mode not only prevents moving axially between axle and shaft coupling significantly, and, also subject to very big axial force, there is transmission moment of torsion big, the effect that accuracy of alignment is high.
