Abstract
The utility model discloses a slewing bearing lip sealing device, including the sealing strip, the side of the horizontal part of sealing strip is provided with sealing convex block. The utility model provides a slewing bearing lip sealing device more, it can fill the sealing strip installation back and the bearing between the clearance, further improves the sealed effect of sealing strip.
Description
Technical Field
The utility model relates to a slewing bearing lip sealing device.
Background
At present, the slewing bearing sealing strip is widely used on a large-scale bearing, and is generally arranged outdoors, so that the maintenance cost after the fault occurs is high, and the requirement on protection is high. The existing situation is as follows: after the sealing device is installed, a larger or smaller gap exists in the area A shown in the figure, and the gap also exists during the bearing anticorrosion treatment in the early stage, so that the situation that the anticorrosion measures cannot meet the requirements appears in the area after sand blasting → zinc spraying → paint spraying, and then after the sealing device is installed and delivered, the gap is exposed to the natural environment, and the problem of early corrosion and the like can occur among the areas along with the prolonging of time, so that the service life of the whole machine is seriously influenced.
Disclosure of Invention
The utility model aims to solve the technical problem that, overcome prior art not enough, provide a slewing bearing lip sealing device, it can fill the sealing strip installation back and the bearing between the clearance, further improves the sealed effect of sealing strip.
In order to solve the technical problem, the technical scheme of the utility model is that:
a multi-lip sealing device of a slewing bearing comprises a sealing strip, wherein a sealing convex block is arranged on the side surface of the horizontal part of the sealing strip.
Further, the cross section of the sealing lug is triangular.
Further, the cross section of the sealing lug is square.
Having adopted above-mentioned technical scheme, the utility model discloses an increase a triangle-shaped or square little boss on the sealing strip, make this region clearance be in a confined state after the installation is accomplished, external rainwater, sand and dust, sunshine and air can not invade in this airtight region, reach the effect of extension whole bearing life.
