Oil film bearing for intelligent rolling mill

Abstract

The invention relates to an oil film bearing of an intelligent rolling machine which comprises the oil film bearing of the rolling machine; the outer end of the oil film bearing of the rolling machine is radially provided with a small displacement sensor; the signal extension line of the displacement sensor extends to the outside of a bearing box holding the oil film bearing of the rolling machine, and is connected to a secondary meter by an externally arranged preamplifier. The invention can realize the online detection and monitoring of the oil film thickness of the rolling machine. If a supporting roller and a roller bearing are intelligently located and mounted in pairs, then the mounting concentricity of the two bearings of the roller is judged according to the data of the oil film thickness of the bearings at the two sides, thus being capable of realizing to detect the mounting precision of the bearing online and improving the quality of the rolled product. The oil film bearing of the intelligent rolling machine is combined with the theoretical arithmetic result of the oil film thickness of the oil film bearing of the rolling machine so that the service life of the oil film bearing of the rolling machine can be evaluated. The oil film bearing of the intelligent rolling machine leads the sensor to be protected, and leads a signal line to be easily led out of the bearing box. The sensor is arranged approaching to the end part of the bearing; the oil film pressure of the bearing at the location is smaller and is close to the pressure outside the end part of the bearing, thus being easy to seal. The oil film bearing of the intelligent rolling machine is suitable for the oil film bearing of the rolling machine with a wall thickness larger than 20mm.

Description

technical field [0001] The invention relates to an intelligent rolling mill oil film bearing, which is an intelligent rolling mill oil film bearing which intelligently transforms the original rolling mill oil film bearing, and ingeniously installs a displacement sensor at a special position to realize online detection of the oil film thickness of the bearing. It belongs to the field of heavy industry and iron and steel industry, and is mainly used in the rolling mill industry. Background technique [0002] Rolling mill oil film bearings are the main components of rolling mills in the iron and steel industry. The quality of rolling mill oil film bearings directly affects the life and service life of backup rolls, rolls and rolling mills. The change of the oil film thickness of rolling mill oil film bearing has a direct impact on the quality of rolling products. In the past, the oil film thickness of rolling mill oil film bearing could not be detected online. It is complicat...
