Description
Technical field
It the utility model is related to shaft coupling, and in particular to a kind of high-accuracy magnetic shaft coupling of self-lubricating.
Background technology
In a variety of plant equipment, shaft coupling is generally indispensable parts, and traditional shaft coupling need to pass through actively
Axle and driven shaft are coupled to each other to transmit moment of torsion, and the shaft coupling of this kind of structure setting is complicated, and the accuracy of manufacture is high, easily mill
Damage, fault rate are higher.For the shaft coupling of traditional structure, in the market occurs utilizing the shaft coupling for being provided with permanent magnet, this kind
Although the shaft coupling of mechanism can overcome the subproblem present in traditional shaft coupling, exist volume it is larger, installation inconvenience
And service life it is short the problem of.Simultaneously for the lab space of some low-temperature high-vacuum high-purities, such as the detection of liquid xenon dark matter
Device, forbid adding lubricating oil during shaft coupling use, avoid the pollution of environment.
Utility model content
The problem of existing for prior art, the purpose of this utility model, which is to design, provides a kind of the high-accuracy of self-lubricating
Magnetic shaft coupling.
The high-accuracy magnetic shaft coupling of described self-lubricating, including the outer rotor that is arranged on driving shaft and be arranged on driven
Internal rotor on axle, seal isolation set is provided between the internal rotor and outer rotor, it is characterised in that the seal isolation set
Installation cavity is provided between outer rotor and internal rotor, first is provided with the installation cavity between seal isolation set and outer rotor
Bearing, the seal isolation, which is covered in the installation cavity between internal rotor, is provided with second bearing.
The high-accuracy magnetic shaft coupling of described self-lubricating, it is characterised in that the clutch shaft bearing and second bearing are respectively provided with
There are two.
The high-accuracy magnetic shaft coupling of described self-lubricating, it is characterised in that the clutch shaft bearing and second bearing be from
Lubricate PEEK plastic bearings.
The utility model is simple in construction, reasonable in design, by the clutch shaft bearing and second bearing of setting, convenient installation, from
And installation effectiveness is improved, while the setting of self-lubricating PEEK plastic bearings, it can effectively avoid magnetic transmission loss of efficiency, failure
Rate is low, service life length.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
In figure：1- outer rotors, 2- internal rotors, 3- seal isolation sets, 4- installation cavitys, 5- clutch shaft bearings, 6- second bearings.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in figure 1, the high-accuracy magnetic shaft coupling of the utility model self-lubricating, including outer turn be arranged on driving shaft
Son 1 and the internal rotor 2 being arranged on driven shaft, seal isolation set 3 is provided between internal rotor 2 and outer rotor 1, is installed to realize
It is convenient, installation cavity 4, seal isolation set 3 and outer rotor 1 are provided between seal isolation set 3 and outer rotor 1 and internal rotor 2
Between installation cavity 4 in be provided with clutch shaft bearing 5, is provided with second in the installation cavity 4 between seal isolation set 3 and internal rotor 2
Bearing 6, and clutch shaft bearing 5 and second bearing 6 are provided with two, to ensure the cleaning of lab space, by clutch shaft bearing 5 and
Two bearings 6 are disposed as self-lubricating PEEK plastic bearings, and the setting can effectively avoid pollution of the lubricating oil to vacuum space, simultaneously
Avoid magnetic transmission loss of efficiency.
Installation of the present utility model and the course of work：
The shaft coupling separation sleeve 3 using being fixed from flanged with cavity window flange bolt, between realize static seal.Examination
The inner chamber body and external cavity for testing cavity realize isolation.Wherein inner chamber body is high vacuum environment, and outer chamber is atmospheric environment, driving
Power is connected on unofficial biography 1.Internal rotor 2 links with actuator in cavity.Passed between internal rotor and outer rotor by magnetic couple
Lead torque and realize that synchronous axial system moves, and be isolated set isolation simultaneously.External contaminants can not be entered by separation sleeve 4 tests
Chamber.And between separation sleeve 4 and internal rotor it is the self-lubricating PEEK plastic bearings taken, avoid lubricating oil and other maintenances are brought
Pollution.
