Abstract
The invention discloses a magnetic coupler which comprises a driving shaft, a driven shaft, an outer rotor and an inner rotor. The driving shaft is fixedly connected with the outer rotor. The driven shaft is fixedly connected with the inner rotor. A spacer sleeve is arranged between the outer rotor and the inner rotor. The spacer sleeve covers the inner rotor to be embedded into a connecting cavity of the outer rotor. At least one driven permanent magnet is fixed to the outer surface of the inner rotor in the axial direction. A driving permanent magnet corresponding to the driven permanent magnet is arranged on the inner side of the connecting cavity of the outer rotor in the axial direction. The magnetic coupler has the advantages that the driven shaft and the driving shaft are in non-contact driving through the driven permanent magnet in the inner rotor and the driving permanent magnet in the outer rotor, the driven permanent magnet and the driving permanent magnet are matched with each other, the driven shaft can be sealed in the spacer sleeve, and therefore zero leakage is achieved; due to the fact that the driving shaft and the driven shaft are independent from each other, maintenance is quite convenient.
Description
Technical field
The present invention relates to a kind of shaft coupling for connecting driving shaft and driven shaft, particularly a kind of magnetic shaft coupling of the contactless transmission high to seal request.
Background technology
Shaft coupling is widely used on various universal machine, is used for connection two axles to make it together rotate, with transmitting torque and motion.Traditional shaft coupling all must by the transmitting torque that interconnects of driving shaft and driven shaft, and its complex structure, the accuracy of manufacture is high, easily causes the destruction of parts during overload.When particularly driving shaft and driven shaft are operated in and need in two kinds of mutually isolated different mediums, potted component must be used to carry out movable sealing, so just existence or increasing rotational resistance ensure that sealing reliably, or the poorly sealed problem producing leakage.In addition, along with the wearing and tearing, aging of potted component, can aggravate to leak, in the system especially existed at pernicious gas (harmful liquid), just pollute the environment once leakage, threat to life.
Summary of the invention
The object of this invention is to provide a kind of can to realize between driving shaft with driven shaft and, not by directly contacting the transmission just carrying out wind tunnel, realize the magnetic shaft coupling of zero leakage.
The present invention is achieved by the following technical programs: a kind of magnetic shaft coupling, comprise driving shaft, driven shaft, external rotor and internal rotor, described driving shaft is fixedly connected with external rotor, driven shaft is fixedly connected with internal rotor, be provided with separation sleeve between described external rotor and internal rotor, described separation sleeve is wrapped in internal rotor and embeds in the connection chamber of external rotor; The outer surface of described internal rotor is fixed with at least one piece of driven permanent magnet vertically, and the inner side that described external rotor connects chamber is in axial direction provided with the active permanent magnet corresponding with driven permanent magnet.
In order to ensure power transmission more steadily with safe and reliable, the quantity of described driven permanent magnet and initiatively permanent magnet is four pieces, and four pieces of driven permanent magnets are distributed in the exterior periphery of internal rotor, corresponding with driven permanent magnet in the connection chamber that initiatively permanent magnet is distributed on external rotor.
The conveniently installation of driven permanent magnet, described internal rotor exterior periphery aspect is provided with permanent magnet mounting groove in axial direction.
Beneficial effect: the present invention, by the driven permanent magnet that cooperatively interacts in inner and outer Rotator and initiatively permanent magnet, becomes contactless transmission by between driven shaft and driving shaft, driven shaft can be sealed in separation sleeve, thus zero leakage; Due to driving shaft and driven shaft separate, therefore safeguard get up also very convenient.
