Abstract
The utility model is related to technical field of mechanical processing, more particularly to a kind of oil sealing sealing device is made of a moving ring assembly and a stationary ring；Moving ring assembly includes magnetic pole, rotating ring piece and rotating ring ring body, and magnetic pole slot is opened up in rotating ring ring body, and magnetic pole and rotating ring piece are inlayed in magnetic pole slot, forms Mounted moving ring；Stationary ring is monoblock type stationary ring；The magnetic pole uses permanent-magnet material；The material of stationary ring is chromium steel.The utility model structure is easy for installation, not only reduces the axially mounted size of moving ring assembly, and more make moving ring assembly follows that performance is more preferable, and compensation performance is more excellent.This structure is replaced commonly using the elastic force of spring or bellows by the magnetic force between magnetic pole and stationary ring, and the adhesive force of rotating ring and stationary ring is made to be guaranteed, and more closely, structure is reduced for fitting, while being not in that the generation for playing phenomenon is lost in spring or ripple pipe choking.
Description
Technical field
The utility model is related to technical field of mechanical processing, more particularly to a kind of oil sealing sealing device.
Background technology
Various rotating machinerys, such as：Bearing housing, gear-box, speed reducer lubricating oil block and dust-proof occasion in, tradition use
Outside framework oil seal and labyrinth seal carry out sealing lubricating oil.Because outside framework oil seal is made using rubber material substantially, intolerant to abrasion,
And it is generally interference fitted between outside framework oil seal and axis.Equipment is after operating after a period of time, between outside framework oil seal and axis
Radial clearance become larger, lead to oil leakage.Labyrinth seal also will appear a small amount of leak case because there is gap.Leakage
Lubricating oil is often thrown out of along rotary shaft, and injection is everywhere.It is leaked in air, causes serious environmental pollution, it is right
Whole scene forms prodigious security risk, and environmental requirement is more not achieved.
The former quality heterosis and reasonable cost become substitute outside framework oil seal, labyrinth seal ideal oil sealing.It closes
The designing of reason, good material, make it possess the service life longer than outside framework oil seal, 1.5 years projected lives.
Pump is a kind of appliance arrangement of trandfer fluid, transfer of highly viscous medium pump in petrochemical industry, such as wet crude, slag
The medium containing larger particles such as oil, slurry, sewage disposal.Present mechanical seal all by spring as medium in, equipment is passed through
After the operating of a period of time, because dielectric viscosity is larger or the reasons such as impurity is more make spring follow the string, sealing is caused to be let out
Leakage.The medium of leakage is often thrown out of along rotary shaft, and injection is everywhere.Especially have some mechanical seals occur leakage with
Afterwards, in dielectric leakage to air, serious environmental pollution is caused, great security risk is caused to whole scene, is more reached not
To environmental requirement.
Utility model content
In order to solve the above-mentioned technical problem, the utility model discloses a kind of oil sealing sealing devices.
Specific technical solution is as follows：
A kind of oil sealing sealing device, the oil sealing sealing device are made of a moving ring assembly and a stationary ring；It is described dynamic
Ring assemblies include magnetic pole, rotating ring piece and rotating ring ring body, and magnetic pole slot is opened up in the rotating ring ring body, and magnetic pole is inlayed in magnetic pole slot and is moved
Ring plate forms Mounted moving ring；The stationary ring is monoblock type stationary ring；The magnetic pole uses permanent-magnet material；
The material of the stationary ring is chromium steel.
Compared with prior art, the utility model has the advantages that：
The utility model magnetic pole uses the permanent-magnet material of global general-use, and magnetic force is stronger more longlasting, oil sealing rotating ring and stationary ring
Adhesive force is guaranteed, and more closely, the stationary ring of monoblock type designs minimal deformation when ensureing processing, the chrome steel of stationary ring for fitting
Material is more wear-resistant, and rubbing surface makes friction coefficient bottom out using grinding technics.Structure is easy for installation, not only reduces dynamic
The axially mounted size of ring assemblies, more make moving ring assembly follows that performance is more preferable, and compensation performance is more excellent.This structure by magnetic pole and
Magnetic force between stationary ring replaces commonly using the elastic force of spring or bellows, and the adhesive force of rotating ring and stationary ring is made to be guaranteed, and fitting is more
Closely, structure is reduced, while being not in that the generation for playing phenomenon is lost in spring or ripple pipe choking.
