Abstract
The utility model relates to a novel sliding bearing sealing device which comprises the labyrinth sealing between a bearing body and a shaft, and is characterized in that an oil thrower is fixedly connected on the shaft through a screw; the labyrinth sealing is fixedly connected with a bearing, and in labyrinth groove fit with the oil thrower; an outer-turning hook is arranged at the top end of the oil thrower; and the labyrinth sealing is provided with a groove which is opposite to the top end of the oil thrower. The sealing device has the advantage that oil can be prevented from leaking. Except for the labyrinth sealing, the oil thrower is arranged at the fit part of the bearing body and the shaft, and then the oil leakage phenomenon is solved.
Description
Technical field
The utility model relates to a kind of novel sliding bearing seal arrangement.
Background technique
Leakage of oil takes place in conventional bearing portion easily, this is because bearing support before is labyrinth sealing with an axle cooperation place, though intercepted the outflow with lubricant oil of entering of a part of dust like this, but some lubricant oil can overflow, so just waste lubricant oil greatly, and made bearing wear and tear easily.Therefore improve the seal arrangement of bearing portion, can increase the working life of bearing greatly.
Summary of the invention
The purpose of this utility model is the problem that the sliding bearing seal arrangement only depends on the outflow of the existing lubricant oil of labyrinth sealed in the solution prior art, and a kind of novel sliding bearing seal arrangement is provided.The utility model designs the improvement of novel sliding bearing sealing, comprise the labyrinth shape sealing of bearing support and between centers, it is characterized in that: on axle, connect a disc by screw, the labyrinth shape sealing is fixedlyed connected with bearing support, cooperate for maze trough between labyrinth shape sealing and disc, there is the hook that turns up on the top of disc, and it is relative with the hook that turns up on disc top to be sealed with a groove at labyrinth shape.The utility model has the advantages that: prevent leakage of oil.Bearing support and axle cooperation place add a disc again except that the labyrinth shape sealing, so just solved oil leakage phenomenon.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise the labyrinth shape sealing 3 of 2 on bearing support 1 and axle among the figure, it is characterized in that: by screw 4 fixedly connected discs 5, labyrinth shape sealing 3 is fixedlyed connected with bearing support 1 on axle 2, and labyrinth shape seals 3 and cooperates for maze trough 6 with 5 of discs.There is the hook 7 that turns up on the top of disc 5, and has a groove 8 relative with the hook 7 that turns up on disc 5 tops in labyrinth shape sealing 3.
When sliding bearing rotates, inner lubricant oil is along axle 2 past exosmosing, when running into disc 5 and climb up disc 5 edges, centrifugal force by disc 5 gets rid of down, inner lubricant oil can't near labyrinth shape seal 3 and disc 5 between, even having a spot of lubricant oil to cross disc 5 edges goes forward side by side into the groove 8 of labyrinth shape sealing 3, still can be sealed 3 groove 8 by labyrinth shape stops, the lubricant oil of minute quantity is stopped by the maze trough 6 of last labyrinth shape sealing 3 with 5 of discs again, like this with regard to dust-tight immersion and grease proofing outflow well.
Claims (2)
1, the improvement of novel sliding bearing sealing comprises the labyrinth shape sealing of bearing support and between centers, it is characterized in that: connect a disc by screw on axle, the labyrinth shape sealing is fixedlyed connected with bearing support, labyrinth shape seal with disc between cooperate for maze trough.
2, by the improvement of the described novel sliding bearing sealing of claim 1, it is characterized in that: there is the hook that turns up on the top of disc, and it is relative with the hook that turns up on disc top to be sealed with a groove at labyrinth shape.
