A Combined Split Sliding Bearing Supporting a Rod Rotor

Abstract

The invention discloses a combined split sliding bearing for supporting a pull rod rotor, which comprises a bearing seat assembly, a bearing bush and a floating sealing ring; the bearing bush is arranged in the bearing seat assembly, and floating sealing rings are arranged at both ends of the bearing bush in the bearing seat assembly; The bearing seat assembly includes the outer body of the bearing seat and the inner body of the bearing seat. Both the outer body of the bearing seat and the inner body of the bearing seat are semi-circular. The openings of the inner bodies of the two bearing seats are arranged symmetrically to form the inner bearing seat. The outer bearing seat is set to form an outer bearing seat; the outer bearing seat is set outside the inner bearing seat; the bearing bush and the floating sealing ring are arranged inside the inner bearing seat; the present invention forms a closed oil groove through the close cooperation of the outer body of the bearing seat and the inner body of the bearing seat, Relying on the structure of the bearing seat itself, the lubrication method of single hole oil supply and lubrication on both sides can be realized. The design is ingenious and reasonable, the cold oil supply is sufficient, the lubrication performance is good, the oil returns quickly, and the installation is convenient.

Description

technical field [0001] The invention belongs to the field of sliding bearings, in particular to a combined split sliding bearing supporting a pull rod rotor. Background technique [0002] The sliding bearing works smoothly, reliably and without noise. When the sliding bearing is working, a thin oil film is required between the bearing bush and the rotating shaft for lubrication. The sliding surface is separated by the lubricating oil without direct contact, which can greatly reduce the friction loss. and surface wear, the oil film also has a certain ability to absorb vibration. When the bearing is directly lubricated, the cold oil can quickly enter the bearing bush, thereby reducing the temperature of the bearing bush and the journal. [0003] On the one hand, sliding bearings will generate friction due to the contact between the journal and the bearing bush during work. If the cold oil supply is insufficient, or the hot oil does not return quickly under the condition of ci...

Problems solved by technology

[0003] On the one hand, sliding bearings will generate friction due to the contact between the journal and the bearing bush during work. If the cold oil supply is insufficient, or the hot oil does not return quickly under the condition of circulating pressure oil supply, it will cause surface heating, wear and even "Seizure"; on the other hand, when the tie rod rotor rotates at high speed, the lubricating oil is adsorbed on the surface of the journal. In this state, the lubricating oil will splash inside the bearing and overflow to both ends of the bearing. When the positive pressure value is greater than the sealing positive pressure value of the oil seal, it will cause the oil seal to leak
