Description
Technical Field
The utility model relates to a conticaster equipment field specifically is a continuous casting roller bearing frame.
Background
The continuous casting roller bearing seat is used for bearing billets formed by a continuous casting machine, the temperature of the billets reaches hundreds of degrees, and the distance between the bearing seat and the billets is only about 30mm, so the temperature of the bearing seat is very high, if effective cooling measures are not taken, a lubricating oil channel is easy to block due to high-temperature carbon deposition, and the bearing can be damaged quickly without lubrication.
Therefore, the bearing seat of the continuous casting billet roller adopts an inner water-cooling bearing seat and adopts oil-gas lubrication, namely, gas and lubricating oil are mixed in an oil-gas mixing device, the gas blows the lubricating oil to flow on the pipe wall, and an oil-gas pipeline is connected to the bearing seat, so that continuous oil supply of a lubricating point can be realized. The gas is the power for blowing the lubricating oil to flow along the pipe wall, can also take away the heat generated by the bearing, and simultaneously forms positive pressure in the bearing chamber, thereby avoiding the outside pollutants such as water, particle impurities and the like from entering the bearing, and ensuring the good running state of the bearing.
Among the prior art, the oil gas pipe of conticaster has generally been installed on the bearing frame, and the bearing that uses is double-row tapered roller bearing, and oil gas gets into the bearing from slot and three aperture in the middle of the bearing outer lane, because the slot size is less, and the size of three aperture is also very little, and the bearing receives the toasting of high temperature steel billet, and lubricating oil is the easy carbon that binds blocks up and blocks up slot and aperture, leads to oil gas to be blockked up and can not get into the bearing, and the bearing loses the lubrication and damages the locking soon.
To the problem in the above-mentioned background art, the utility model aims at providing a continuous casting roller bearing frame.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a continuous casting roller bearing frame to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a continuous casting roll chock, comprising: the bearing end cover is fixedly arranged at the upper end of the water-cooling bearing seat, and an oil gas inlet hole is formed in the outer side of the bearing end cover; a rotary oil seal is arranged in the bearing end cover, and a shaft is movably arranged in the rotary oil seal; the upper end of the bearing end cover is opposite to the nozzle, and one end of the nozzle is communicated with the spray cooling pipe; and the left side and the right side of the lower end of the water-cooling bearing seat are respectively provided with an inner water-cooling water outlet pipe joint and an inner water-cooling water inlet pipe joint.
Compared with the prior art, the beneficial effects of the utility model are that:
the bearing seat of the continuous casting roller changes the oil gas inlet from the upper surface of the bearing seat to the position of the side surface of the bearing seat aiming at the bearing roller, and oil gas is directly sprayed on the bearing roller, so that the mode that the oil gas enters the bearing through narrow and long passages such as a groove and a small hole of the outer ring of the bearing is avoided, and the possibility of blockage of the oil gas passage due to high-temperature carbon deposition is reduced;
in addition, an external spraying cooling water pipeline and a nozzle are arranged above the bearing seat, cooling water is directly sprayed to the outer surface of the bearing seat, the temperature of the bearing seat is reduced, and the condition that lubricating oil blocks a lubricating oil channel due to high-temperature carbon deposition is avoided. The double pipes are arranged simultaneously, so that the normal running state of the bearing is ensured, and the service life of the bearing is prolonged.
