Abstract

The invention discloses a vertical roll bearing device. The vertical roll bearing device comprises a vertical roll shell, a bush and a vertical roller. A fastening bolt is mounted in the center of thebottom end of the vertical roller. The outer wall of the top end of each socket head cap screw is provided with a spring washer. The top ends of the two sides of the bush are each provided with a sealing washer. An anti-loosening drill is arranged at one side of the bottom end of each locking nut. A vertical roll bearing is arranged at the inner side of the bush. The outer walls of the two sidesof the bush are each fixedly connected to the inner wall of the vertical roller through an O-shaped sealing ring. According to the vertical roll bearing device, the outer walls of the two sides of thebush are each fixedly connected to the inner wall of the vertical roller through the corresponding O-shaped sealing ring, and the sealing performance of the vertical roll bearing is improved; the effect that cooling liquid, oxide skin and other impurities are prevented from entering a shell and the bearing can be effectively achieved; and the vertical roll bearing device is easy to apply and popularize.

Description

technical field [0001] The patent of the invention relates to the technical field of steel rolling finishing in the iron and steel metallurgy industry, specifically a vertical roller bearing device. Background technique [0002] In recent years, with the rapid development of my country's industry, great changes have taken place in my country's steel product market, and the requirements for rolling mills have also increased accordingly. The vertical roller bearing is an important part of the rolling mill, and its performance is an important indicator to measure the performance of the rolling mill. The vertical roller bearings currently on the market generally use general-purpose tapered roller bearings. The inner sleeve of the double-row tapered roller bearing and the shaft have a clearance fit, which is not resistant to impact, and the inner sleeve is prone to destructive bursting. Secondly, due to its structural form, the addition of bearing lubricating oil is insufficient...
