Description
Technical field
The utility model is related to mechanical engineering technical field of sealing technology, and in particular to a kind of railway truck bearing cylinder and circle
Bore mixed type coaxial-type magnetic sealing device.
Background technology
Magnetic seal is also known as magnetic coupling, it is to realize the non-contact of torque using the permanent magnet principle that there is a natural attraction between the sexes
Formula is transmitted, and metal separation sleeve may be implemented to be absolutely sealed, therefore magnetic seal has " zero leakage " and reduces vibration and noise etc.
Advantage.Magnetic seal mainly includes the structure of three kinds of forms：End-surface type magnetic seal, coaxial-type magnetic seal and parallel-axis type
Magnetic seal.The torque that coaxial-type magnetic seal transmits in three kinds of structures is maximum, but the torque transmitted is still smaller, still can not
Meets in transmission field the needs of to high torque (HT).
China railways have more than 50 ten thousand lorries and apply sealed double-row taper roll bearing, since lorry uses condition
Harsh and speed-raising operation requirement, bearing seal problem seem very prominent.According to the statistics before 10 years, in repair in shop lorry, bearing
It causes the roller scrapped to account for about always to scrap several 43% because the cleannes for sealing, lubricating are bad, outer ring is about 63%；Duan Xiu
In, bearing fault accounts for about the 72% of its total failare caused by poor sealing.The failure mode of China railways freight car bearing sealing
It is mainly shown as:Initial stage running-in temperature increases, seal closure loosens, oil sealing falls off, lip is seriously worn with aging, seal failure is early,
Service life is low etc., and bearing is caused to get rid of oil, permeability, and into sand-lime and water, lubricating grease is rotten or lacks, and bearing generates point, impression, rust
Erosion, discoloration and early stage stripping etc., this not only makes bearing be not achieved projected life, but also causes a lot of hot axis or even cut axis thing
Therefore jeopardize traffic safety.And the existing method for improving coaxial-type magnetic sealing device torque about railway axle seldom refers to.
Application publication number is that the patent of invention of " CN106122486A " discloses a kind of increase magnetic sealing device torque
Method applies the pyramid type coaxial-type magnetic sealing device such as lower structure：Including power rotor, driven rotor, separation sleeve, outer
Permanent magnet, interior permanent magnet are respectively equipped with axis hole in the middle part of the power rotor and driven rotor；The power rotor it is interior

Parallel with the inner wall of power rotor, there are gaps between power rotor, driven rotor and separation sleeve；The power rotor
Multiple annular groove I are arranged in interval on inner wall, and multiple annular groove II are arranged in interval on the outer wall of the driven rotor, described
Annular groove I and annular groove II correspond；The outer permanent magnet of installation, the annular groove in the annular groove I
Permanent magnet in installation in II；The each group of mutual corresponding outer permanent magnet is opposite with the magnetic line of force direction of interior permanent magnet.
Above-mentioned pyramid type coaxial-type magnetic sealing device separately designs power rotor and driven rotor for pyramidal structure,
And groove is opened up in the outer wall of the inner wall of power rotor and driven rotor respectively, permanent magnet is packed into groove, pyramidal structure can
To increase contact area, to improve magnetic torque, and the transmission efficiency of torque is improved；Increase permanent magnet in a circumferential direction
Logarithm accordingly increases the magnetic energy product in gap between the inner wall of power rotor and the outer wall of driven rotor, to enhance magnetic
The effect of power sealing, overcomes the small defect of existing magnetic sealing device torque, substantially increases the reliability of magnetic drives.But
The torque for being above-mentioned magnetic sealing device transmission may be still smaller, still cannot be satisfied the need to high torque (HT) in transmission field
It asks.
Therefore, to those skilled in the art, a kind of railway truck bearing cylinder how is provided to mix with circular cone
Type coaxial-type magnetic sealing device further increases the magnetic that the torque in magnetic seal is successfully applied to it high torque requirements
Power transmission field has great importance.
