Description
Technical field
The present invention relates to a kind of permanent magnetism variable torque variable speed coupling, especially a kind of vertical permanent magnetism variable torque variable speed coupling with heat abstractor.
Background technology
In the existing mechanical drive system, great majority adopt the mechanical attachment mode of rigidity between motor and the load equipment, like various machenical couplings.Rigid mechanical connects transmits the vibration between motor and the load equipment mutually, amplifies the influence of vibration, is prone to break down; In addition, centering required height when positive coupling was installed, and general coaxiality error is not more than 0.05mm, and some high-precision transmission system then requires coaxiality error to be not more than 0.02mm, and installation difficulty is big; And the amplification coaxiality error then can make driveline vibrations obviously increase.Because practical operation situation is complicated and changeable, strict centering how when no matter installing, equipment operation all can produce vibration after a period of time, thus equipment life is shortened in accelerated wear test.When fault takes place, be difficult for accurate tracing trouble the source takes place, especially when the stall fault takes place, understand badly damaged motor, transmission mechanism and load equipment.
At present, the permanent magnetism hitch bar that multinomial patents such as existing ZL 00811078.6, ZL98802726.7 provide can address the above problem.Utilize between conductor rotor and the p-m rotor of permanent-magnet eddy current coupling principle and do not have mechanical attachment; Rely on magnetic force to come transmitting torque, realized " the soft connection " between motor and the load equipment, make the vibration between load and the motor isolate, be independent of each other; Can reduce the centering installation accuracy requirement between motor and the bearing axle greatly; When apparatus overload, can also protect equipment, " soft start " function is provided, effectively stop the stall fault.Permanent magnetism shaft coupling transmission device have soft connection, soft start, environmental protection, energy-conservation, simple in structure, adaptability by force, advantage such as non-maintaining basically.
At present; Permanent magnetism shaft coupling transmission device has been applied to industrial circles such as chemical industry, petrochemical industry, electric power; As produce the equipment such as pump and blower fan of systems such as water system, circulation, stable high-pressure fire fighting water system, steam condensate system, sewage disposal; Effectively overcome traditional water pump etc. and regulated flow through throttle or baffle plate; Throttling loss is big, efficient is low, valve member wearing and tearing or problems such as distortion is serious, system failure rate is high, motor and load equipment life-span weak point, maintenance cost height, can under the prerequisite that does not influence production, reduce production run cost and raising equipment service efficiency significantly.
Existing permanent magnet clutch is ripe at transmitting torque and lower-powered applications.Because the conversion of the magnetoelectricity between conductor and the magnet rotor, induction produce vortex flow and can produce a large amount of heats, not only make the portion of energy loss, transmission efficiency reduces, and also possibly change damage equipment because of the too high meeting of device temperature brings the mechanical structure fit clearance.High temperature can cause that also magnetic force decays rapidly, directly causes equipment failure.The corresponding bigger permanent magnet clutch complex structure of power, volume is bigger, just is difficult in the place of some limited space use.
Utilize the shaft coupling of permanent-magnet eddy current principle generally to be made from multiple components; Its core component---conductor and p-m rotor system generally are made up of a plurality of (2 ~ 3) rotor; Each rotor arrangements is in different axial positions, and the structural detail that a plurality of difference in functionalitys are arranged on each rotor along the footpath, hoop distributes; Under different slips, rotating speed and rotor clearance such as need regulate at working condition requirement; Shaft coupling becomes many (electricity, magnetic, power, heat etc.) couplings, multiple degrees of freedom, ten minutes complicated dynamic system; Each rotor-support-foundation system possibly belong to the high-order flex rotor; Relate to high-order flexible rotor dynamic balance problem, receive the influence of the dynamics under structure and the different rotating speeds thereof very big.Transmitted power is bigger, rotating speed is high more, slewing range is wide more, and environment for use is harsher, and structure is more complicated, and is just high more to the requirement of the structural design of system, dynamic balancing, heat radiation etc.With this; Though utilize permanent magnetism to drive and speed regulating device have had on mechanism and can realize soft start, vibration damping, outstanding superiority such as energy-conservation; But require to improve constantly along with its application at each industrial circle extensively reaches gradually, technological difficulties such as its dynamic balancing under different capacity, moment of torsion, different rotating speeds operating mode, heat radiation also more and more highlight its development and the bottleneck restriction applied.
For the occasion that the speed change demand is arranged, there are the harmonic pollution network system that produces because of frequency control in the frequency control of using at present, fluid power coupling iso-variable velocity technology and to environment for use drawback such as have relatively high expectations.
For the occasion that becomes moment of torsion and speed change demand is arranged simultaneously, can use except utilizing the permanent magnet induction principle still not have reliable technique at present.
At present, the design of the permanent magnet clutch that level (horizontal) is installed with use morely, and be fit to vertical installation, high efficiency and heat radiation, have shaft coupling concurrently and transmission function is less in the organization plan of the permanent magnetism shaft coupling speed change gear of one.
