Intelligent support sliding bearing device with adjustable clearance and clearance adjustment method

Abstract

The invention discloses an intelligent support sliding bearing device with adjustable clearance and a clearance adjustment method. The intelligent support sliding bearing device comprises a support sliding bearing, an inclined block is arranged under the support sliding bearing, a guide rail is arranged under the inclined block, the bottom surface of the inclined block is matched with the guide rail in a sliding mode, the inclined block moves in the axial direction of the guide rail, the top surface of the inclined block is an inclined plane with a taper of 1 to 125, a pushing mechanism is arranged at one end of the inclined block, the other end of the inclined block is connected with a reset spring, and a vertical displacement sensor and a horizontal displacement sensor are respectively used for detecting the vertical radial displacement and the horizontal radial displacement of a rotor; the vertical displacement sensor and the horizontal displacement sensor are connected with the input end of a monitoring controller, and the output end of the controller is further connected with the control signal input end of a servo motor; when the rotor vibration is too large, signals collected by the sensors are sent to the controller, the controller controls the servo motor to make a certain action, and the clearance between the bearing and the shaft neck is changed, so that the elliptical bearing play a role, the rotor amplitude is reduced, and the whole system has a good effect of vibration reduction and suppression.

Description

technical field [0001] The invention belongs to the field of rotor bearing system dynamics test technology and design of rotating machinery, and in particular relates to an intelligent supporting sliding bearing device with adjustable clearance and a clearance adjustment method. Background technique [0002] In industrial production, sliding bearings work smoothly and reliably. In many important occasions, such as generator sets, steam turbine sets, rolling mills, high-speed spindles and other important fields occupy an important position. According to its load bearing mode, it can be divided into: thrust sliding bearing and radial sliding bearing, and radial sliding bearing can be divided into: round pad sliding bearing, three oil lobe sliding bearing, dislocation pad sliding bearing, tilting pad sliding bearing, elliptical plain bearings. When designing sliding bearings, they are often designed for a specific working condition, but in actual engineering applications, the...
