Intelligent variable elliptic sliding bearing assembly

Abstract

The invention discloses an intelligent variable elliptic sliding bearing assembly. The assembly comprising a variable elliptic sliding bearing and a detection control loop, wherein the variable elliptic sliding bearing is divided into an upper sliding bearing and a lower sliding bearing, the two sliding bearings are oppositely arranged, the upper sliding bearing is fixed, and the lower sliding bearing can swing around a pivot in certain range; in the detection control loop, a displacement transducer is arranged close to the elliptic sliding bearing and is connected with a controller, the controller is connected with a servo motor and an alarm, the servo motor is connected with an inclined slide block by virtue of a transmission screw, and the inclined slide block is connected with the lower sliding bearing. The assembly can change pivot angle direction and pivot angular dimension of the lower sliding bearing when rotating around the pivot by manually or automatically regulating the operating condition of the serve motor, thus flexibly adjusting the working condition of the sliding bearing and adapting to the requirement of different working conditions.

Description

technical field [0001] The invention belongs to the technical field of bearing devices, and relates to a sliding bearing device, in particular to an intelligent state-adjustable elliptical sliding bearing device, which is suitable for radial sliding support whose working conditions vary within a large range. Background technique [0002] Sliding bearings work smoothly, reliably, and without noise. If fluid lubrication can be ensured, friction and wear can be greatly reduced. 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 thrust sliding bearings according to the working load they bear, and radial bearings can be divided into ordinary round tiles (such as figure 1 a), elliptical tile (such as figure 1 b...

Problems solved by technology

Traditionally, these sliding bearings are designed based on one or several specific working conditions. However, in actual production and operation, the working conditions of sliding bearings may need to be changed frequently. Different, to adjust its working speed, in order to ensure the safe operation of the sliding bearing of the unit, it is necessary to ensure that the unit maintains a stable working state, which will cause a shortage of power resources during the peak period of power consumption, and cause a shortage of power resources during the low peak period of power consumption. Causes waste of power resources; similarly, in large-scale core key equipment that bears complex impact loads, such as crushers, rolling mills, and large motors, the working load may change drastically, and its working conditions may be within a wide range Sliding bearings with a specific parameter are often unable to meet frequently changing working conditions. Therefore, complex working conditions will cause wear and tear of sliding bearings and shorten bearing life. If these core equipment are damaged, the corresponding production line will be shut down, resulting in huge economic losses for related enterprises.
