Abstract
The utility model relates to a lubricating oil sealing device for a bearing, in particular to a magnetic mechanical oil seal. The utility model adopts the technical scheme as follows: the magnetic mechanical oil seal comprises a bearing cover, a moving ring and a stationary ring, wherein an O-shaped ring is sheathed on the stationary ring; the stationary ring is fixed on the bearing cover through a positioning pin; a magnet is arranged on the moving ring; a dynamic sealing part is embedded on the moving ring; an axial O-shaped ring is sheathed on the moving ring; the moving ring is sheathed on a shaft; and the bearing cover is buckled at one end of the shaft. The magnetic mechanical oil seal has the advantages of simple structure, convenience in use, low cost and long service life.
Description
Technical field
The utility model relates to a kind of bearing lubrication oil sealing device, is a kind of magnetic mechanic oil seal concretely.
Background technique
At present, most of machinery are at the seal aspect of bearing oil, use more be sealed into felt sealing, labyrinth seal etc., traditional felt sealing contacts with rotatingshaft owing to lip, can cause the sclerosis of lip limit after the long-time running, and then cause the wearing and tearing of axle, finally cause seal failure; Improved labyrinth seal owing to exist the gap, inevitably exists leakage when stopping operating, can not be used for vertical structure.Cause its leakiness big, working life is short, and the big shortcoming of maintenance workload.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of magnetic mechanic oil seal of simple in structure, good sealing effect is provided.
Its technological scheme is: it comprises bearing cap, rotating ring and stationary ring, be with round section joint ring on the stationary ring, stationary ring is fixed on the bearing cap by locating stud, rotating ring is provided with magnet, be inlaid with dynamic seal on the rotating ring, be with axial round section joint ring on the rotating ring, moving ring sleeve is contained on the axle, and bearing cap is fastened on an end of axle.
The utlity model has advantage simple in structure, easy to use, long service life with low cost.
Description of drawings
Accompanying drawing is a kind of embodiment's of the utility model a structural representation.
Among the figure, 1 is bearing cap, and 2 is rotating ring, and 3 is stationary ring, and 4 is round section joint ring, and 5 is locating stud, and 6 is magnet, and 7 is dynamic seal, and 8 is axial round section joint ring, and 9 is axle.
Embodiment
As shown in the figure, a kind of magnetic mechanic oil seal, comprise bearing cap 1, rotating ring 2 and stationary ring 3, be with round section joint ring 4 on the stationary ring 3, stationary ring 3 is fixed on the bearing cap 1 by locating stud 5, and rotating ring 2 is provided with magnet 6, be inlaid with dynamic seal 7 on the rotating ring 2, be with axial round section joint ring 8 on the rotating ring 2, rotating ring 2 is sleeved on the axle 9, and bearing cap 1 is fastened on an end of axle 9.
During work, rotating ring 2 is contained on the axle 9, leans on the sealing between round section joint ring 4 maintenances and the axle 9 and rotating ring 2 is rotated with axle 9, rotating ring 2 is pulled together by magnet 6 and stationary ring 3, and relatively rotate, the sealing between rotating ring 2 and the stationary ring 3 is abutted against and is touched friction and seal, and has long working life.
