Description
Technical field
The present invention relates to technical field of bearings, more particularly to a kind of load sliding bearing.
Background technique
Sliding bearing, the bearing to work under sliding friction.Sliding bearing stable working, reliable, noiseless.Moisten in liquid
Under sliding condition, slidingsurface is separated by lubricating oil without directly contacting, and can also greatly reduce friction loss and surface mill
Damage, oil film also have certain vibration absorption ability.But starting friction resistance is larger.Axis is known as axle journal by the part that bearing supports, with
The part that axle journal matches is known as bearing shell.Sliding bearing application is generally under high speed light loading working condition.
In the operation of sliding bearing, rotor generates natural bow and since installation such as misaligns at the originals due to the gravity of itself
Cause is overlapped the center line of axle journal and bearing bush center line not, to cause bearing shell and axle journal to generate axial axially generating deflection
It touches mill and generates high temperature, touch time consuming one long, the service life of bearing shell and axle journal will substantially reduce.
Summary of the invention
In view of the above-mentioned state of the art, technical problem to be solved by the present invention lies in provide a kind of load sliding axle
It holds, is equipped with and carries component, make it at work, the center line and bearing bush center line of axle journal keep coincidence status, and the two is avoided to touch
Mill, extends the service life of sliding bearing.
The technical scheme of the invention to solve the technical problem is:
It is a kind of to carry sliding bearing, including bearing shell and axle journal, further include equal load components, load component include the first magnet and
Second magnet, axially both ends are correspondingly arranged on the first magnet to bearing shell, and axially both ends are correspondingly arranged on the second magnetic to axle journal
Iron, the first magnet are matched with the second magnet, and the first magnet and the second magnet position adjacent to each other are homopolarity position, in bearing shell
Anchor ring and axle journal outer ring surface are equipped with magnetic iron inhibitory coating.
Preferably, magnetic iron inhibitory coating and bearing shell are all made of nonmetallic materials and are made.
Preferably, the nonmetallic materials for making bearing shell are specially phenolic resin, nylon, polytetrafluoroethylene (PTFE), carbon graphite and pottery
One of porcelain.
Preferably, make magnetic iron inhibitory coating nonmetallic materials be specially in nylon, polyformaldehyde and polytetrafluoroethylene (PTFE) one
Kind.
Preferably, the shape of the first magnet and the second magnet is circular ring shape, the inner ring surface of the first magnet and the second magnet
Outer ring surface be homopolarity position.
Preferably, the first magnet and the second magnet are at least provided with 2.
Preferably, the first magnet and the second magnet are equipped with 2.
The utility model has the advantages that
First magnet can generate repulsion to the second magnet, and repulsion and deflecting force are contrary, therefore can offset deflecting force, axis
The center line of neck and the center line of bearing shell will be maintained at coincidence status, so that axle journal and bearing shell be avoided to touch mill, extend
The service life of sliding bearing；Magnetic iron inhibitory coating plays package protective effect to the first magnet and the second magnet, on the one hand anti-
Only magnet is fallen in bearing working, and the two directly contact is on the other hand avoided to generate abrasion.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 be intermediate bushing of the present invention, axle journal and load component side structure schematic diagram.
Wherein, bearing shell 1, axle journal 2, the first magnet 3, the second magnet 4, magnetic iron inhibitory coating 5.
Specific embodiment
, there are further understanding and understanding in the effect of to make to structure feature of the invention and being reached, to preferable
Examples and drawings cooperation detailed description, is described as follows:
As shown in Figure 1 to Figure 2, a kind of to carry sliding bearing, including bearing shell 1 and axle journal 2, as an improvement of the present invention, also
Including carrying component, load component includes the first magnet 3 and the second magnet 4, and axially both ends are correspondingly arranged on first to bearing shell 1
Magnet 3, axially both ends are correspondingly arranged on the second magnet 4 to axle journal 2, and the first magnet 3 is matched with the second magnet 4, the first magnetic
Iron 3 and the second magnet 4 position adjacent to each other are homopolarity position, and 1 inner ring surface of bearing shell and 2 outer ring surface of axle journal are equipped with magnet protection
Layer 5.
In use, the center line and 1 center line of bearing shell when axle journal 2 are not overlapped, when axially generating deflection, due to being mounted on
First magnet 3 of bearing shell 1 and the second magnet 4 being mounted on axle journal 2 position adjacent to each other are homopolarity position, therefore the first magnetic
Iron 3 can generate repulsion to the second close magnet 4, and repulsion and deflecting force are contrary, therefore can offset deflecting force, axle journal 2
The center line of center line and bearing shell 1 will be maintained at coincidence status, so that axle journal 2 and bearing shell 1 be avoided to touch mill, extend cunning
The service life of dynamic bearing, magnetic iron inhibitory coating 5 plays package protective effect to the first magnet 3 and the second magnet 4, on the one hand anti-
Only magnet is fallen in bearing working, and the two directly contact is on the other hand avoided to generate abrasion.
Magnetic iron inhibitory coating 5 and bearing shell 1 are all made of nonmetallic materials and are made, and nonmetallic materials will not attract 3 He of the first magnet
Second magnet 4, therefore ensure that the effect of load balancing mechanism for carrying component.
The nonmetallic materials for making bearing shell 1 are specially in phenolic resin, nylon, polytetrafluoroethylene (PTFE), carbon graphite and ceramics
One kind, phenolic resin, nylon, polytetrafluoroethylene (PTFE), carbon graphite and ceramics all have outstanding plasticity and higher hardness.
The nonmetallic materials for making magnetic iron inhibitory coating 5 are specially one of nylon, polyformaldehyde and polytetrafluoroethylene (PTFE), Buddhist nun
Dragon, polyformaldehyde and polytetrafluoroethylene (PTFE) all have outstanding low-friction coefficient and high-wear resistance, can 3 He of the first magnet of effective protection
Second magnet 4.
The shape of first magnet 3 and the second magnet 4 is circular ring shape, the inner ring surface of the first magnet 3 and the second magnet 4 it is outer
Anchor ring is homopolarity position, and when the direction of deflecting force changes, mill point is touched in the closest approach of axle journal 2 and bearing shell 1 can therewith
It changes, the repulsion contrary with deflecting force can be generated between the first magnet 3 and the second magnet 4 of circular ring shape at this time,
To offset deflecting force.
First magnet 3 and the second magnet 4 are at least provided with 2, to guarantee 1 both ends stress equalization of axle journal 2 and bearing shell.
First magnet 3 and the second magnet 4 are equipped with 2.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of skill in the art that it still can be right
Technical solution documented by previous embodiment is modified, or is replaced on an equal basis to part of technical characteristic；And these
