Embodiment 1

[0039] Such as figure 1 Shown: In this embodiment, a sliding bearing 1 is respectively installed at both ends of the rotating shaft. The liquid inlet end of the filter 2 is connected with a coarse filter module, and the liquid inlet end of the coarse filter module is connected with the oil outlet holes of two sliding bearings 1 at the same time, and an oil supply tank is arranged between the filter 2 and the oil cutting device 4 3, so that lubricating oil can be provided, and when adding lubricating oil to the system, it can be added through the oil supply tank 3. The liquid outlet of the heat exchanger 6 is connected with a buffer tank 5, and the liquid outlet of the buffer tank 5 communicates with the oil inlet holes of the two sliding bearings 1 at the same time, thereby realizing the circulation oil supply lubrication.

[0040] Such as figure 2 As shown: the filter 2 includes a glass substrate 11 , a magnet on the lower side of the glass substrate 11 , a filter plate 36...

Embodiment 2

[0052] Such as Figure 9 As shown: the difference between embodiment 2 and embodiment 1 is: the upper part of the hose groove 16 is symmetrically provided with extrusion guide rails 1601 on both sides, and the right end of the extrusion guide rail 1601 is in the shape of an arc gradually upward from left to right. Extruding block 35 is installed in hose groove 16, and the left end of extruding block 35 is the inclined shape gradually upward from left to right. It is connected and drives the extruding block 35 to move to the right and separate from the extruding guide rail 1601 . When the wheel disc 17 drives the cutting and pressing head 18 to rotate, the cutting and pressing head 18 pushes the extrusion block 35 to move to the left, and under the action of the extrusion guide rail 1601, the extrusion block 35 moves downwards to squeeze the oil hose, squeezing The briquetting block 35 moves to the left at the same time, thereby conveying the lubricating oil and improving the ...

Abstract

The invention provides a self-adaptive circulating lubricating system for a sliding bearing and belongs to the technical field of bearing lubricating systems. The self-adaptive circulating lubricating system is characterized by comprising a filter (2), a pressure-cutting oil supply device (4) and a heat exchanger (6); the liquid outlet end of the filter (2) communicates with the liquid inlet end of the pressure-cutting oil supply device (4), and the liquid outlet end of the pressure-cutting oil supply device (4) communicates with the liquid inlet end of the heat exchanger (6); the sliding bearing (1) is provided with an oil inlet hole and an oil outlet hole, the liquid inlet end of the filter (2) communicates with the oil outlet hole of the sliding bearing (1), and the liquid outlet end of the heat exchanger (6) communicates with the oil inlet hole of the sliding bearing (1); and a rotary shaft for mounting the sliding bearing (1) is connected with the power input end of the pressure-cutting oil supply device (4). The self-adaptive circulating lubricating system for the sliding bearing has the beneficial effects that by simplifying an external circulating structure of the sliding bearing, lubricating oil is circulated by the adoption of the same power source, the capacity of a main drive device is fully utilized, the occupied area is saved, and the consumption of the electric energy is reduced.

Description

technical field [0001] An adaptive sliding bearing circulation lubrication system belongs to the technical field of bearing lubrication systems. Background technique [0002] Hydrodynamic sliding bearings are widely used in large high-speed rotating machines. With the increase in speed, capacity and size of rotating machinery, the stability and lubrication characteristics of the rotor-bearing system are constantly being challenged. For the stability, it is generally believed that the support stiffness and damping are one of the decisive reasons for the rotor stability margin, although different sliding bearing structures directly lead to changes in stiffness and damping. However, after the design and installation of the sliding bearing is completed, its working conditions, such as oil supply pressure, temperature rise, etc., become the main factors affecting the stability of the rotor-sliding bearing system. [0003] The lubrication characteristics are mainly determined by...
