Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like figure 1 As shown, a gap-adjustable intelligent support sliding bearing device includes a support sliding bearing, a vertical displacement sensor 10, a horizontal displacement sensor 9, and a controller 15, and the support slide bearing is provided, and the slurry block 3 is provided below. The guide rail 2, the bottom surface of the oblique block 3 is slidably fitted, and the oblique block 3 moves axially along the guide rail 2, the top surface of the slope 3 is 1: 125 taper, slide on the guide rail, and the shaft watt can withstand heavy The load, and reliably operate, which can greatly reduce the implantive force required for the oblique block movement; one end of the oblique block 3 is provided, and the other end of the oblique block 3 is connected to the reset spring 4, the slope 3 is disposed in the support seat 1 The reset spring 4 is disposed between the ...

Abstract

The invention discloses an intelligent support sliding bearing device with adjustable gap and a gap adjustment method. The block moves along the axial direction of the guide rail. The top surface of the inclined block is a slope with a taper of 1:125. One end of the inclined block is provided with a pushing mechanism, and the other end of the inclined block is connected to a return spring. The vertical displacement sensor and the horizontal displacement sensor are used to detect the rotor respectively. The vertical radial displacement and horizontal radial displacement; the vertical displacement sensor and the horizontal displacement sensor are connected to the input terminal of the controller, and the output terminal of the controller is also connected to the input terminal of the servo motor control signal; when the rotor vibration is too large, the sensor collects The received signal is sent to the controller, the controller controls the servo motor to make a certain action, changes the gap between the bearing and the journal, makes the elliptical bearing play a role, reduces the rotor amplitude, and makes the whole system have a good vibration reduction and vibration suppression effect.

Description

Technical field [0001] The present invention belongs to the dynamic test technique of rotor bearing system, and the mechanical design areas, and more particularly to a gap-tunable intelligent support sliding bearing device and a gap adjustment method. Background technique [0002] In industrial production, the sliding bearing is smooth and reliable. In many important occasions, such as genetic sets, steam turbine, rolling mills, high-speed spindles, etc. have an important role. According to its loaded load, the thrust sliding bearing and radial sliding bearing, and the radial sliding bearing can be divided into: round watt slide bearing, three oil leaf sliding bearing, misaligning tile slip bearing, can drain the wad sliding bearing, ellipse Slide bearings. When designing the sliding bearing, it is often designed for a certain specific condition, but in the actual engineering application, the working condition of the sliding bearing will change as some factors change, so that the...
