An Intelligent Bearing Support Device with Adjustable Geometric Dimensions

Abstract

The invention discloses an intelligent bearing support device with adjustable geometric dimensions. The intelligent bearing support device comprises a slide bearing support mechanism with adjustable geometric dimensions, and a detection control system, wherein the slide bearing support mechanism with the adjustable geometric dimensions is divided into a slide bearing and a support structure, the support structure is divided into a support seat and a support cover which are oppositely installed, the bearing is installed in the support structure, the bearing is divided into an upper bushing and a lower bushing which are oppositely installed, the upper bushing is fixed, and the lower bushing slides in the support structure up and down; and in the detection control system, a displacement sensor is installed in the vicinity of the slide bearing and connected with a state monitoring controller, the controller controls a servo motor to rotate, the servo motor drives a lead screw to rotate, the lead screw drives tapered iron to move, and the lower bushing of the bearing slides up and down due to the movement of the tapered iron. The device is capable of monitoring the running condition of a rotor in real time, adjusting the up-down slide distance of the lower bushing of the bearing through the rotation of the servo motor, judging the changed working condition, and adjusting the geometric dimensions of the bearing to ensure the stable and safe running of a rotor bearing system.

Description

technical field [0001] The invention relates to the technical field of rotor bearing system testing machines, in particular to an intelligent sliding bearing support device with adjustable geometric dimensions, especially suitable for radial sliding support of rotor bearing systems under time-varying working conditions. Background technique [0002] The sliding bearing works smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear, and the oil film also has a certain ability to absorb vibration. Although in general working conditions, such as machine tools, gearbox cars, etc. are replaced by rolling bearings, they still play an important role in many important occasions, such as generator sets, steam turbines, rolling mills, and high-speed spindles. Sliding bearings can be divided into radial sliding bearings and th...
